Features 18 SUBURBAN FARMING NEAR THE RUNWAY The Ahernes are the last farming family from the parish of Ballyphehane farming between Cork city and the 4* Cork International Airport Hotel. Milking 100 cows under one roof in a stress free environment.
20 MAKE GOOD DECISIONS EARLY TO INCREASE FUTURE PROFITABILITY It has been shown that 22 to 24 months is the most cost effective age for first calving, writes Cargill’s calf and heifer specialist, Bianca Theeruth.
A
s we approach spring and longer days we can look back at a winter that was kind to most farmers in terms of weather. The milk price is going in the right direction and nobody seems to know what Brexit really means. Until we hear something really negative we can only stay positive and watch the milk price. For this edition we visited the Aherne farm near Cork airport. Pat Aherne designed and built a shed layout which encompasses everything under one roof. The immediate positive is the ease of working and the ability to control all aspects of the operation from calving to computer systems in an accurate and stress free environment. Grass Rotation: Having better grass earlier in the spring might seem an obvious way to increase overall yield per cow. Michael Egan and Michael O Donovan set out the best way to manage grass rotation to achieve optimum yield at minimum cost. Spring nitrogen:We all know that the price of fertilizer has increased dramatically over the last six months. In this situation it is very important to use the correct type of fertilizer at the correct rate of application without wastage to get the best return. Calf management:As the average herd size increases and the calving window narrows, it is really critical to have a plan for calving and rearing of calves. More and more research is confirming that a good start is half the battle…this means high quality colostrum. Emer Kennedy gives us chapter and verse. Feeding Higher Yielding Cows:Valerie Hobson, the animal nutritionist with Quinns of Baltinglass, sets out a feeding plan for high yielding cows if say grass is poor or paddocks are wet. She explains that high energy levels need to be maintained or it may be difficult to recover if they drop too low. On Farm Investments: On some occasions it is difficult to establish if a farmer will get a positive return on a capital investment even if it is grant aided. Philip O’ Connor of IFAC gives a means of testing the investment plan for cash flow effects and overall return. Pathways: Tom Ryan gives the spec and the benefits.We hope it makes for interesting reading..

22 SPRING NITROGEN: A KEY INGREDIENT FOR GRASS IN SPRING One of the most important factors affecting spring grass growth on Irish dairy farms is the date and quantity of spring N fertiliser application, write Michael O’Donovan and Michael Egan of Teagasc, Moorepark.

Increased focus must be placed on utilising grass early in lactation to increase overall milk and herbage production. Michael Egan & Michael O’Donovan,Teagasc, Moorepark report.
32 GOOD CALF MANAGEMENT IN A CROWDED CALVING PERIOD Getting enough immunoglobulins from colostrum immediately after birth is the single most important factor in ensuring the health & productivity of the calf, writes Emer Kennedy,Teagasc, Moorepark.
36 OPTIMUM ON–FARM MILK STORAGE TEMPERATURE AND TIME PERIOD The initial quality standard of milk entering a bulk tank will directly influence the quality of that milk when collected by the milk processor. But the interim storage conditions of temperature and time period of storage also have a major impact on the quality, writes Dr. David Gleeson,Teagasc, Moorepark.

A recent Teagasc study estimated the cost of rearing replacement heifers in Ireland at approximately €1500. Inadequacies in management of calf health on many farms are adding to the already significant cost of heifer rearing as well as reducing the lifetime potential of those heifers, according to Joanne Cregg, MSD Animal Health,Technical advisor.
44 ON FARM CAPITAL INVESTMENTS – PRESSURE TEST RETURNS Poorly planned capital investments tie up valuable cash in the business which can reduce profitability, writes Philip O’ Connor, Agriculture Support Manager with IFAC.
46 FEEDING THE SPRING CALVING DAIRY COW A major drop in protein % and/or low milk protein can be an early warning that cows are underfed, writes Valerie Hobson, Animal Nutritionist, Quinns of Baltinglass Ltd.

NEWS GRASS QUALITY – THE MOST VALUABLE TRAIT As Teagasc highlight that each 1% increase in grass quality is worth 0.33 litres of milk per cow per day, this is a trait that is increasingly being recognised as critical when selecting grass varieties. Perennial ryegrass is an extremely digestible, high quality feed and will result in much greater animal performance in terms of milk production and liveweight gains when compared to old permanent pasture. So it is worth ensuring your swards contain a high proportion of perennial ryegrass. Other factors which will influence sward quality are soil pH and fertility status, grazing management, pre and post-grazing residuals, and good soil structure. It is important to note that there are large differences between varieties of perennial ryegrass with regard to digestibility. The Teagasc Pasture Profit Index (PPI), has highlighted these differences in economic values (€ per ha/year). The PPI quantifies the economic merit of individual perennial ryegrass varieties by determining the performance of varieties across a number of key traits; spring, summer and autumn DM yield, Silage, Persistency, and Quality. In the quality sub-indices of the PPI, the difference between the varieties with the highest quality value (AberGain) and the lowest quality value (Boyne) is €103 per ha/year for quality alone. This is highly significant in highlighting how each variety can contribute to animal performance; whether milk production or liveweight gains. AberGain is the highest ranked variety on the PPI for quality (+€64 per ha/year), and also the highest ranked late

heading tetraploid overall, with the total PPI value at €169 per ha/year. AberChoice is the top ranked late diploid on the PPI list for both quality (+€63 per ha/year) and total PPI value (€175 per ha/year). Ensuring your grass seed mixture contains varieties which excel in quality will result in a more palatable, higher quality sward which will increase animal performance compared to a low quality sward.

eNEWS TRUMP WORRIES US FARMERS After keeping the rural voters who put him in office on edge until the last moment, President Trump nominated Sonny Perdue, a former Georgia governor now heading a global agribusiness trading company – Perdue Partners LLC – to be his agricultural secretary. The night following Trump’s announcement, Perdue took the stage at the Bipartisan Inaugural Gala Celebrating American Agriculture and promised to “make American agriculture great again”. The good news is that Perdue clears a bar far too few Trump cabinet nominees seem to meet – he has experience in government and management, as well as knowledge about the department he’s been selected to lead. This is a relief, given the breadth of authority of the US Department of Agriculture (USDA), an agency of nearly 100,000 employees with an annual budget over $140m. The bad news is, Perdue also has a great deal in common with other cabinet nominees: a whole lot of money, close ties to big industry and a track record that bodes poorly for the interests of the broader constituency of the USDA: the American people. As Georgia governor from 2003-2011 (and 2009 Biotech Governor of the Year), he supported factory farm expansion, cracked down on immigration and opposed air quality regulation. He famously thought the best tactic for a state suffering from drought was a prayer vigil. And at a time when food systems contribute as much as 25% of global greenhouse gasses, Perdue joins the growing ranks of cabinet nominees who deny climate change science, calling it “a running joke” and a reason “liberals have lost all credibility”. A telling signal of what to expect from Perdue is the reaction to his
14
appointment from commodity associations, traders and brokers. The National Chicken Council called him “a welcomed choice from the ‘Broiler Belt,’” while The National Cattlemen’s Beef Association praised his “unique and expert understanding of both the business and scientific sides of agriculture”. The American Farm Bureau Federation celebrated the “outstanding nominee … a businessman who recognizes the impact immigration reform, trade agreements and regulation have on a farmer’s bottom line”. Missing here is a key clarification and something purposefully obscured by these voices: not all farmers have the same bottom line, so whose will Perdue prioritize? To be clear, we are not splitting hairs – agribusiness and its boosters intentionally portray their interests as the interests of “American agriculture”, as if that represented a homogenous block, implying that all farmers and ranchers benefit equally from policies that benefit Big Ag. There are indeed farmers who share interests with large scale corporate agribusiness – according to the USDA, over 80,000 farmers post sales over $1m annually. Yet these farmers make up less than 4% of the farming population, and there are over 2 million farmers with sales below this figure. Important to recognize are the roughly 700,000 growers – a third of American farmers – who earn between $10,000 and $250,000 annually, comprising arguably the agricultural equivalent of the middle class. It is these farmers, the rank and file of American agriculture, who are unlikely to be served by Perdue’s agenda. Full article originally published on www.theguardian.com

In the post antibiotic era Pat has one piece of advice for farmers, “to think outside the box” and not to be afraid to look at alternatives like homeopathy and herbal. With a comfortable office on the upper deck, CCTV, a good computer system, calving/ holding pens etc, he believes that he made the correct decision. It was tempting to go for a larger farm with 150/200 plus cows but he is comfortable with what he has. Pat believes that in future the focus will be on milk quality over milk quantity. Who knows?

CALF NUTRITION. COMMERCIAL FEATURE
MAKE GOOD DECISIONS EARLY TO INCREASE FUTURE PROFITABILITY
P
It has been shown that 22 to 24 months is the most cost effective age for first calving, writes Cargill’s calf and heifer specialist, Bianca Theeruth. roducers are advised not to be tempted to cut corners in calf nutrition and management to save costs. “The consequences of this can be long lasting,” says Bianca Theeruth. “Maintaining target growth rates in calves and youngstock is like achieving high interest rates – it’s an investment for the future,” says Ms Theeruth. “Less expensive and lower-spec diets can look appealing for producers contemplating their cash flow, but it’s often a false economy. Lower growth rates can affect age at calving, and this can affect yields – both of which impact on lifetime productivity. “It’s been shown that 22 to 24 months is the most cost-effective age at first calving,” she said. “Research indicates that 55 % of Irish born dairy heifers calve between 22 to 26 months and 25 % fail to make it to calving”. There’s lost potential here. Calving older heifers increases rearing costs and reduces first lactation yields. Lifetime productivity is lower.
As a word of warning Ms Theeruth warns farmers not to let colostrum get contaminated.“This can happen so easily especially if it is collected and then left standing out in the open.The bacteria reproduce rapidly and the total count can double in 20 minutes in warm colostrum. It needs to be stored in sanitised containers, cooled quickly and stored in the fridge.” Simple improvements can often pay off. Ms Theeruth advises,“farmers should remember to feed extra milk replacer in low temperatures. Otherwise growth rates will drop as calves use more energy for maintenance – to keep warm – rather than for growth. “And I often see farmers getting confused with concentration rates. Milk replacer is usually made up to a litre and not added to a litre so for a concentration of 12.5 %, 125g of milk powder plus 875 ml of water is needed rather than 125g of milk powder plus 1000ml of water which would give 1.125litres and a concentration of 11.1 %.
“Maintaining target growth rates in calves and youngstock is like achieving high interest rates – it’s an investment for the future” According to Ms Theeruth, “cutting corners in dairy cow feeding “If the management isn’t right the milk replacer won’t do its job. and management manifest themselves fairly immediately, but slips “Even a top quality product won’t mask poor management or provide and getting into bad habits in calf rearing may not be seen for a while. an excuse for inadequate health, hygiene or housing.

FERTILISER APPLICATION
SPRING NITROGEN A KEY INGREDIENT FOR GRASS IN SPRING One of the most important factors affecting spring grass growth on Irish dairy farms is the date and quantity of spring N fertiliser application, write Michael O’Donovan and Michael Egan of Teagasc, Moorepark.
T
he application of N in early spring increases grass growth to allow the majority of the nutrient requirements of cows to be met from grazed grass. A number of experiments in Ireland have shown responses ≥10 kg DM/kg N applied in spring. McCarthy (1984) reported that the date in spring at which a given grass yield is obtained could be brought forward by three weeks when N fertiliser was applied at the correct time. Precise prediction of the appropriate N application date is difficult because of variation in soil and air temperatures from year to year. Date of N application will also depend on when grass is required and if it can be utilised as grazed grass. Murphy (1977) and O’Donovan et al., (2004) showed that there is considerable variation in the optimum time for applying N but concluded that the optimum date for the southern half of Ireland was usually in mid- to late-January while Stevens et al., (1989) found that earlyto mid-February was the optimum time for the midlands and north of Ireland. Van Burg (1968) reported that first N applications in late February result in lower DM production, especially when combined with an early harvest date. A three year study investigating the influence of N rate and timing of application on spring DM production at Moorepark. The results suggest that for the March 18th harvest N response were 15.7 kg DM/kg N from a January 12th application, 7.3 kg DM/kg N from a February 3rd application and 5.6 kg DM/kg N from a February 23rd application. For the April 8th harvest date the DM responses were 17.6 kg DM/kg N from a 12th January application; 11.4 kg DM/kg N from a February 3rd application
22
and 15.1 kg DM/kg N from a February 23rd application. It was shown that highest DM production was achieved from the January application of nitrogen fertiliser. The effects of “early Spring” application of fertiliser N are summarised in Table 1. This data shows that sizeable responses (>10 kg DM/kg N) to the application fertiliser N can be obtained in early spring from a series of experiments including Grange and Northern Ireland. Clearly, the application of N should be carried out as early as circumstances permit. Table 1.

The optimum level of N used for early grass will depend on grass demand (stocking rate). For most intensive dairy farms in Ireland the optimum level of N to apply is 30 kg N/ha (23 units/ acre) in mid–January to early-February and 56 kg N/ha (46 units/ acre) in March, a total of 85 kg N/ha (70 units/acre) by April 1st for early spring grass (Table 2). In 2016, Pasturebase Ireland (PBI) data found that the majority of farms were applying early spring N fertiliser, with 33 kg/ha (27 units/acre) applied by midFebruary, however there is still quite a large variation in quantity with a range of 0 to 65 kg/ha (0 to 52 units/acre). By April 1st PBI farms had on average 110 kg N/ha (88 units/acre) applied, however there was still a large variation between farms, with a range of 64 to 167 kg N/ha (51 to 134 units/acre). This variation can have a large impact on grass DM production in the spring period, farms who applied less than 100 kg N/ha (80 units/acre) grew 24% (275 kg DM/ha) less DM by April 10th, than farms who had applied 100 kg N/ha or more (80 units/acre).

whereas urea takes 2/4 days to convert to ammonia, provided moisture is present. Losses of N as volatilised ammonia from urea can occur in dry and warm weather conditions. Rainfall will ensure the urea will be washed into the soil, where nitrifying bacteria convert it to ammonium-N and the ammonium-N to nitrate, which is then available for uptake by the plant. At higher temperatures and at low levels of rainfall, large amounts of ammonia gas will be lost to the atmosphere. As a result, grass growth response to urea will be below that of CAN. In optimum conditions, the response to urea can significantly outperform CAN (+33%; see Table 3). Table 3: Relative response (%) of grass growth to application of urea N compared to CAN depending on rainfall and air temperature conditions (values above 100% indicates a grass growth advantage to urea N; values below 100% indicate a disadvantage to urea N) (Source; Grassland soils and fertiliser; digging out the answer, 2011)
Practically, February is a better month for N application at Ballyhaise, Co. Cavan as it is usually associated with lower rainfall and reduced nitrogen losses compared to March. For the past 10 years, rainfall at Moorepark from January to April was 106 mm in January, 53 mm in February, 80 mm in March and 56 mm in April, and for Ballyhaise the comparative figures were 109 mm in January, 80 mm in February, 85 mm in March and 66 mm in April. Annual rainfall for the last 10 years was 1018 mm at Ballyhaise and 1022 Best results from urea fertiliser will be obtained when application mm at Moorepark. is followed by approximately 10 mm of rainfall within three days.

More than 90% of world industrial production of urea is destined for use as a nitrogen-release fertiliser; urea is made up of 46% nitrogen, the form of N is Ammonium (NH4+). Urea is positively charged, while clay particles are negatively charged, and therefore urea is held by clay particles provided moisture is present. It is readily absorbed by plants, and is the dominant source of N for plant growth. Calcium ammonium nitrate is made up of 27% N, the form of N is 50% nitrate (NO3) and 50% ammonium.

Currently, urea is 20% cheaper per kg N than CAN. Therefore, because urea is cheaper than CAN in terms of €/kg N applied, and response rates are similar urea is the more cost-effective fertiliser to apply during the spring or as long as weather conditions allow.

SPRING GRASS ROTATION
WINNING THE SPRING GRAZING AND ROTATION CHALLENGE Increased focus must be placed on utilising grass early in lactation to increase overall milk and herbage production. Michael Egan and Michael O’Donovan,Teagasc, Moorepark report.
INTRODUCTION Milk production in Ireland is seasonal and grass based, with calving date targeted to coincide with the start of grass growth. Feed supply in the form of grazed grass matches or exceeds the demand for spring calving dairy cows from approximately midApril to mid-October. A significant quantity of milk is produced in the shoulder periods (spring and autumn) of the year and so it is important to exploit the potential of grazed-grass available during this period (Roche et al., 1996), because it is a low cost and high quality feed (Finneran et al., 2012). The availability of sufficient herbage for grazing in early spring is possible through appropriate autumn grazing management and through grass budgeting in spring (Murphy, 1977; O’Donovan et al., 2002; Kennedy et al., 2006). Increasing stocking rates (an additional 100,000 cows calved in spring 2016; ICBF, 2016) and compactness of calving (a reduction in mean calving date of five days and an improvement in six week calving rate of 6% - 2011-2015; ICBF, 2016) (Figure 1) has increased spring feed demand on dairy farms. Extra grass must be grown and utilised in this period to avoid increases in supplementary feed use. PastureBase Ireland (PBI) (Hanrahan et al., 2015) data shows that insufficient grass quantities on dairy farms at calving commencement and a large variation is spring grass growth (Figure 2), resulting in high supplementation levels. Figure 1: Trends for mean calving date and 6 week calving rate for cows In spring 2016 daily grass growth rates reduced by 40% from in the tops 10% (Broken red line) and national average (Solid blue line) EBI mid-March to early–April; this had a significant effect on grass Reference (ICBF 2016) availability in the second rotation and subsequently grass allocation per cow.

SPRING GRASS ROTATION early to mid-April. This varies from farm to farm and year to year but the most important aspect of grazing management is to make good use of spring grass. The period from calving to breeding is a critical time for both herd and grassland management. Cows should be turned out to grass as soon as possible post-calving (1 – 2 days). Profitability will increase as higher cost feeds such as grass silage and concentrate are reduced or eliminated from the diet. This paper will discuss spring grazing management, PBI findings, and will outline developments in spring grazing management on farm in six key areas, 1) spring rotation planner, 2) farm cover management, and 3) wet weather management.

SPRING GRAZING MANAGEMENT 1. SPRING ROTATION PLANNER Grazing management in the first two months after calving largely determines spring grass growth and how well fed the herd are at the onset of breeding. The spring rotation planner (SRP) is a tool to guide farmers in tracking the area of the farm grazed off at different time points in the spring. It divides the area of the farm into weekly portions and takes the guesswork out of grazing management over this critical period. The best way of managing grass in spring is to set out the area to graze weekly and implement the plan during the spring period. The SPR works off simple parameters; turnout date, grazing area and the targeted first rotation finish date. The SRP shows the proportion of the farm to be grazed by three key points in the early grazing season March 1st, March 17th and the desired end of the first grazing rotation (approximately April 1st –- 10th). The SRP, will not inform the farmer the quantity of grass available in the paddock at grazing, so farmers will have to monitor the quantity of grass in each paddock. Supplementation and what levels to be offered should be managed according to post-grazing residuals; post-grazing residual height should be maintained at 3.5 cm during the 1st rotation. If postgrazing height exceeds 3.5 cm based on the daily area allocation, demand per day must be increased by reducing/eliminating supplementation. If post-grazing residual height falls below 3.0 cm, supplementation must be increased. PastureBase Ireland data for 2016 (n= 65 farms) shows on a range of soil types that the average turnout date was February 8th with a range from January 16th to March 6th. Soil type has an impact on initial turnout date; a typical SRP can be seen in Table 2a. In general the dates by which a certain proportion of the farm should be grazed are 10 days later on heavy or slow-growing farms compared to dry farms (Table 2b). The targeted end date of the first rotation may need to be adjusted, given some of the weather challenges encountered during the spring period, so it is important to monitor spring farm cover during this period.

• To have 66% of the farm area grazed by March 17th, and to stretch the remaining 40% until early April (and later if growth rates are below normal). The effect of spring DM production on annual DM production has previously been shown (O’Donovan et al., 2015), with spring DM production accounting for 43% of the variation in annual grazing DM production. It’s clear Irish farms are not achieving the required targets set by the SRP and are finishing the first rotation too late.

AVERAGE FARM COVER AND FEED BUDGET on grazed swards compared to ungrazed swards at this time of A grazing management plan in place for spring is crucial, in year. Kennedy et al.

This results By grazing a certain area per week, a wedge shape grass supply is at first in a decline in average farm cover, a plan is required to control the rate of farm cover decline, otherwise farm covers will created. The importance of creating a wedge-shape grass supply is crucial to ensure enough grass is available in the second rotation. be run down too far. Higher stocking rate will place added pressure on available feed Data from PBI shows that in 2016 on average 21% (range 0 to 52%) of the grazing platform was grazed in February, which may resources on farms. The development of disciplined feed budgeting during spring will be among the greatest opportunities for Irish dairy have been accounted for by unfavorable weather conditions in spring 2016. In spring 2015, however, had similar results, with, on farmers to expand their businesses profitably while continuing to harness the benefits of a predominantly grass-based diet. Farm average, 22% (range 0 to 46%) of the grazing platform grazed in February. These figures are below the target of a minimum of 30% stocking rate and how you manage your pasture through autumn and spring will dictate how much purchased supplements you grazed by March 1st. The target is set to grow 1200 kg DM/ha from the 1st January to 10th April. PastureBase Ireland data (2015 will need during the 1st rotation. Opening spring farm cover has a large impact on impending spring herbage allocation to the & 2016) shows that for every 1% area grazed in February an additional 14 kg DM/ha is grown by April 10th, which equates to herd. Opening with a low average farm cover means there is less
“The development of disciplined feed budgeting during spring will be among the greatest opportunities for Irish dairy farmers to expand their businesses profitably while continuing to harness the benefits of a predominantly grass–based diet” an additional 125 kg DM/ha grown on farms when 30% of the grazing platform grazed in February compared to 21% grazed in February. In 2015 and 2016 farms who grazed ≥ 30%, grew, 133 kg DM/ha more than farms that grazed < 30% (1086 and 1220 kg DM/ha, respectively), an 11% increase in spring grass. On a 40 ha farm this means that there is an additional 5320 kg DM available to the grazing animals, which can substantially reduce the requirement for additional supplementation. If it is proving difficult to meet the target proportions grazed, low pre-grazing covers should be grazed first as this will increase area allocated per day, and allow the SRP planner targets be achieved. The 2015 & 2016 PBI data shows mean spring grass production from January 1st to April 10th was 1239 kg DM/ha on farms grazed by April 10th compared to 994 kg DM/ha for farms grazed after April 10th, 20% difference. The farms that had finished the first rotation by April 10th had 29% of the area grazed by March 1st. The February grazed area had an adequate regrowth interval to ensure availability of grass for the start of the second rotation. The main points of the SRP are: • To get freshly calved cows out grazing as soon as possible post-calving. Feed allowance increases steadily from calving until the breeding season • To graze a minimum of 30% of the farm area during February to stimulate regrowth for the second rotation, which will commence between April 1st and 10th depending on grass growth rates.

available grass available for grazing. In 2015, the autumn closing cover on 65 PBI farms was 782 kg DM/ha, (range 312 to 1153 kg DM/ha), the corresponding opening farm cover in 2016 was 998 kg DM/ha, (range 417 to 1307 kg DM/ha) which equated to an overwinter growth rate of approximately 3.5 kg DM/ha/day. Most farms at high stocking rates (>3 LU/ha) require a farm cover of approximately 900 – 1,000 kg DM/ha at the start of calving. The ideal average farm cover of >800 kg DM/ha on February 1st allows a farm operating at a SR of 2.5 to 2.9 LU/ha to turn freshly calved cows out full time to a predominantly grass diet and extend the 1st rotation to April 5th, and require less than 300 kg concentrate/cow. Figure 3 shows the target average farm cover during spring to allow a farm carry a stocking rate of 2.5 to 2.9 LU/ha to achieve a high proportion of grazed grass in the diet while reducing supplementation. A large variation in opening farm cover, such as that seen in spring 2016 has huge implications at farm level. McCarthy et al (2015) showed that a 260 kg DM/ha reduction in opening farm cover (Clonakility research farm) resulted in an additional 150 kg DM/cow of silage been fed. Previous research shows that higher opening farm covers result in greater early-spring growth rates, and greater cow intakes and milk production. The amount of feed on the farm at calving is strongly linked to the amount of milk produced from pasture before summer without supplements. O’Donovan et al (2015) reported that an additional 100 kg DM/ha opening far cover results in an extra six days grazing, while PBI data shows that every 100 kg DM/ha increase in opening farm cover, pasture

SPRING GRASS ROTATION grass with an appetite, they then graze continuously for a fixed period of time, when animals finish grazing and lie down or walk, they are brought back to a stand-off area or shed. On/off grazing takes advantage of the animal’s natural grazing pattern, letting them graze when they choose to graze, i.e. directly after milking. Kennedy et al., (2009) concluded that if access time to pasture is restricted, then the total access time should be 6 hours and that it needs to be split into 2 distinct periods. Kennedy et al., (2009) reported that animals with access to pasture for 6 hours/day divided into 2 × 3 hour intervals after morning and afternoon milking, had similar milk production to animals with full access to pasture. Likewise, animals with 2 × 3 hour access time had 95% of the daily DM intake of animals with full access to pasture. There was no reduction in milk production or loss of body condition score. This minimises soil damage but ensures that grass is being well utilised. Kennedy et al., (2011) reported that when supplementation (access to silage when housed) during on/off grazing is practiced there was no benefit in terms of milk production compared to no access to silage when housed. Sward utilization, however, was reduced from 82% to 67% by adding silage into the animal’s diet and grass DM intake was reduced from 12.2 to 9.6 kg/cow/day on 2 × 3 hour with no silage and 2 × 3 hour with access to silage, respectively. If there is sufficient grass available, there is no need to supplement cows with silage when they return indoors. Early spring grazing and grazing during difficult weather conditions is also facilitated by correct infrastructure such as a Figure 3: Recommended average farm cover (Average Farm Cover; kg good network of farm roadways and multiple access points to DM/ha) for a farm stocked at 2.5 to 2.9 LU/ha. paddocks to avoid trampling over the same area multiple times and a good water trough layout to allow the implementation of back fencing/strip grazing. Strip grazing and back fencing are as important during periods of wet weather in autumn as spring. Wet weather management: On/off grazing should be practiced during wet weather to reduce poaching damage growth rate was increased by 3 kg DM/ha/day in early March (Figure 4). A spring feed budget is essential to make the best decisions around managing feed requirements at this time of year. Feed budgets incorporate feed supply and demand, facilitating decision making around feeding cows and maintaining average farm cover. They assist the farmer to predict forward and forecast the amount of feed available and supplementation requirement. Regrowth rates on the grazed ground and average farm cover, must to be monitored particularly from early March, and average farm cover should not be allowed to drop below 450 kg DM/ha at the beginning of April prior to the start of the second rotation (Figure 3).
CONCLUSION The importance of spring grass in the diet of early lactation animals and its impact on subsequent sward production has previously been shown, and management rules have been developed to assist farmers manage spring grass.There needs to be a renewed focus by farmers on early spring grazing. Spring rotation plan targets are not being met by many farmers, and as a result spring DM production on those farms is below that of farms that Figure 4: March grass growth increased by 3kg DM/day for every are reaching the SRP targets. 100kg DM/ha increase in average opening farm cover on Irish dairy Increased focus must be placed on utilising grass early in farms (Pasturebase, 2015). lactation and trying to stimulate high farm grass growth rates earlier (late February/March).

Given the increase in calf numbers over the past number of years, issues such as overcrowding in houses can arise. A few simple steps can help alleviate problems which could potentially occur. Colostrum management is perhaps the most important. Without adequate immunological protection, the newborn calf is more vulnerable to infection, more likely to develop disease and die in the pre–weaning and post-weaning period, have a slower growth rate and for heifer calves a reduced milk production during the first and second lactation. Getting enough immunoglobulins from colostrum immediately after birth is the single most important factor in ensuring the health and productivity of the calf. The most recent results available from the regional vet labs reported that almost 2,500 ZST (zinc sulphate turbidity) tests were completed in 2014 to determine if calves were achieving adequate passive transfer (APT), an indicator of colostrum management. 50% of the samples tested showed failure of passive transfer, i.e. when calves do not absorb enough antibodies. Failure of passive transfer occurs when: i) Colostrum quality is poor (below 50 g/L) ii) Colostrum is fed too late iii) Calves do not receive enough colostrum
T
he 2017 spring calving season is upon us and now is the time to reflect on how last year’s calving season went and what changes need to be made for the coming season. A quick run through the calving/calf shed to make sure you have all the necessary equipment is time well spent. For example, do you need to replace teats on feeders, do you need new ropes for the calving jack, and do you have a rapid test kit for testing the cause of scour outbreaks? Calf rearing on Irish dairy farms is becoming a lot more concentrated. In the past 10 years there has been a 35% increase in the number of calves born to a dairy sire. Add to this that almost 50% of the total numbers of dairy sired calves born in the country are born in February. This results in a lot of calves being born in a short period of time and an increased demand on labour. However, that said dairy farmers have a responsibility to ensure that all calves born on their farms are given the same treatment and the welfare of all animals is considered. Even if you are selling bull calves or heifers that are surplus to requirements it is very important that all calves receive proper colostrum management and are well fed and healthy. Animals which

The simplest way to remember how much colostrum to feed and when to feed it is to follow Animal Health Irelands Colostrum 1, 2, 3 rule. 1. Feed 1st milking only 2. Feed within the first 2 hours of birth 3. Feed 3 litres
HOW TO ENSURE HIGH QUALITY COLOSTRUM Colostrum (biestings) is only the first milk the cow produces after calving; milkings 2 – 6 are called transition milk. When it comes to colostrum management there are a lot of things you can control such as the time after birth when you feed the calf and how much colostrum you feed the calf. Once these guidelines are adhered to the only one unknown in terms of achieving APT is colostrum quality. Colostrum quality is determined by the amount of immunoglobulins, specifically IgG, or antibodies that it contains.The threshold to determine high quality colostrum is 50 mg/ml. A good investment is a Brix refractometer; this simple device allows the quality of colostrum to be determined. A few drops of colostrum are placed on the refractometer, when the eyepiece is viewed by pointing towards natural light the scale is visible. Colostrum which is of high enough quality (>50 mg/ml) to feed to a calf for its first feed is above 22%. If it is below this value it should not be used for a calf’s first feed, it can be fed as a second feed instead. When excess colostrum from healthy cows is available it should be frozen so that it will be available in cases where a cow’s colostrum quality is poor (below 22%) and cannot be fed to a calf as a first feed.

EARLY CALF MANAGEMENT Figure 1. How to use a Brix refractometer to test your colostrum quality
FACTORS WHICH CAN AFFECT COLOSTRUM ARE: • Lactation number – Generally colostrum quality increases with lactation number • Time interval from calving – Colostrum quality decreases as the interval between calving and the collection of colostrum increases. Once collected within 9 hours from calving quality should remain high • Month of calving – Later calving cows can have poorer quality colostrum • Volume of colostrum - As volume increases colostrum quality decreases; this is partly due to a dilution effect.
ENSURING THE CALF GETS ENOUGH COLOSTRUM Calves may not receive enough colostrum for a number of reasons but one of the main contributory factors is leaving the calf with the cow. It is impossible to know how much colostrum the calf has
feeding calves transition milk for at least 2 days after their colostrum feed reduced their odds of being assigned a worse eye/ear and nasal score when they were continually health scored.
FEEDING MILK OR MILK REPLACER Good nutrition is fundamental to animal health, welfare and productivity. Traditional milk feeding systems for dairy calves have been based on daily feeding rates of 8 to 10% of body weight (~4 litres/ day). These ‘restricted’ feeding systems were intended to encourage the calf to eat a greater quantity of concentrate feed from an earlier age; however they seriously limit growth potential as they only allow 20-30% of biologically normal growth and are detrimental to calf health and welfare. A higher plane of nutrition facilitates physiologically appropriate growth rates, better immune function, and lower incidences of disease and mortality. In a recent Moorepark experiment calves were fed 4 litres (~10% of birth bodyweight) or 6 litres (~15% of birth bodyweight) of milk. Calves fed 4 litres of milk were lighter at five weeks of age than those fed 6 litres.At five weeks of age the reticulorumen is still underdeveloped and calves fed a restricted quantity of milk are not capable of increasing intake of starter
“When excess colostrum from healthy cows is available it should be frozen so that it will be available in cases where a cow’s colostrum quality is poor (below 22%) and cannot be fed to a calf as a first feed.” consumed if it is left with the cow. Furthermore, as the calf has no developed immune system it is more susceptible to diseases being shed by the cow. Feeding the calf 8.5% of its birth bodyweight in good quality colostrum (3 litres for a 35 kg calf) within two hours of birth will enable the calf to achieve APT. After 2 hours the ability of the calf to absorb antibodies from colostrum begins to reduce rapidly and ceases completely after 24 hours.
FEEDING TRANSITION MILK No further transport of IgG into the circulation is possible 24 hours after birth. Nonetheless, transition milk (milkings two to six postcalving) fed subsequent to colostrum may have beneficial effects, as it contains a greater concentration of IgG than whole milk and antibodies remaining in the lumen may provide local immunity against enteric pathogens. A Teagasc Moorepark study found that
concentrate and forage to a degree that they can fully compensate for the lower supply of energy from milk. Feeding calves a greater volume of milk tends to reduce the number of days taken to reach a target weaning weight. Furthermore, there was no difference in incidences of diarrhoea between calves fed 4 litres or 6 litres of milk. Weaning calves earlier is desirable from the farmer’s point of view as this saves labour, time and feed costs.
ONCE–A–DAY MILK FEEDING Once daily feeding before calves are four weeks old can create health concerns by overloading the abomasum. In a recent Moorepark experiment calves fed 15% of their birth weight (6 litres) in milk replacer from 4 weeks of age, either once daily or in two equally divided feeds, did not have an increased likelihood of developing diarrhoea. No differences in calf performance or health were observed between calves fed once or twice a day. This provides valuable

information to farmers as it means labour input per calf may be reduced by utilizing a once a day feeding regime in the knowledge that it has no unfavourable repercussions on the growth and health of calves. However, if feeding milk once a day calves still need to be checked thoroughly twice a day.
IS OUTDOOR REARING AN OPTION FOR PRE–WEANED CALVES?
were showing signs of ill-thrift outdoors they were brought back in and treated, they were returned outdoors post recovery. Daily weight gain from birth to weaning was higher for the group of calves reared outdoors (0.54 kg/calf/day) compared to those reared indoors (0.48 kg/calf/day). Number of treatments administered was lowest in the shelter treatment (1 treatment) compared with the indoors and straw treatments (11% and 6%, respectively). Interestingly, it was clear from this experiment that pre-weaning treatment affected post-weaning weight gain: weight of the outdoor reared calves tended to be higher (+9 kg) 72 days after mean weaning date.
Expanding dairy herds often overlook the provision of additional infrastructure for calf rearing during the expansion process.The same is true for farmers with more compact calving patterns. Building new calf houses can be expensive, especially as they are limited to use during the months of calf rearing. Consequently alternative options CONCLUSION have been investigated at Teagasc Moorepark. Giving sufficient attention to detail during the pre-weaning period The experiments completed determined that calves turned out at 4-5 is of paramount importance for all calves.

BULK MILK STORAGE
OPTIMUM ON–FARM MILK STORAGE TEMPERATURE AND TIME PERIOD The initial quality standard of milk entering a bulk tank will directly influence the quality of that milk when collected by the milk processor. But the interim storage conditions of temperature and time period of storage also have a major impact on the quality, writes Dr. David Gleeson, Teagasc, Moorepark.
INTRODUCTION Approximately 85% of milk produced in Ireland is exported as dairy products. The success of this export industry is reliant on the production of high quality milk. Much research work has focused on the quality of milk before it enters the bulk tank, but quality can also be influenced by storage conditions on-farm. The two most relevant parameters are temperature of storage and duration of storage. European Union legislation specifies that milk produced and stored on–farm must be cooled to at least 6°C. In Ireland, milk is usually collected at 48-h intervals, but in spring and winter, the collection interval is often extended to 96 h. Milk processors request that milk be cooled to 2 to 4°C within 2 to 3 h of milking. Milk cooling is responsible for the largest electrical energy consumption on Irish dairy farms. Thus, there may be an economic incentive for farmers to cool and store milk at higher temperatures (e.g., at 6°C compared with 2°C), especially if milk is being stored for an extended duration. However, cooling milk to higher temperatures, in conjunction with longer on–farm storage intervals, may have implications for milk quality, with possible deleterious effects on milk functionality at milk processing facilities. At processor level microbial tests such as the total bacteria count (TBC) and psychrotrophic bacterial count (PBC) are used to characterize raw milk quality, while heat coagulation time (HCT) and rennet coagulation time (RCT) are measurements used to determine milk functionality.

BULK MILK STORAGE
COOLING TEMPERATURES AND STORAGE TIME COMPARED A study was undertaken to investigate the effects of storage temperature and duration on the microbial quality of bulk tank milk when fresh milk is added to the bulk tank twice daily. Previous international studies on milk storage time and temperature have been undertaken at laboratory level, this is the first (to our knowledge) such study undertaken at farm level. Milk was harvested from spring-calving dairy cows after a complete pre-milking teat preparation procedure was undertaken (teats washed, pre-milking teat disinfectant applied, followed by drying with paper towels). Clusters were flushed with water and disinfected with peracetic acid between individual cow milking’s and a recommended equipment cleaning protocol was implemented. The milk from the parlour was diverted three ways through three single-stage plate coolers (milk cooled to 14.5°C before entering the bulk milk tank) and then to three identical bulk milk tanks (Swiftcool, Dairymaster). Each tank had a separate 5.5hp condenser unit. Tanks were set at each of 3 temperatures (2°C, 4°C, and 6°C) on

The two sampling periods were selected to establish if there was a season effect on milk quality when storage period was extended and storage temperature was altered. Bulk tank milk was sampled at 24-h intervals during storage periods of 0 to 96 h at each temperature setting. Milk samples were analysed for a range of microbial tests including total bacterial count (TBC), psychrotrophic bacterial count (PBC),
laboratory pasteurization count (LPC), presumptive Bacillus cereus, and sulfite-reducing Clostridia (SRC). To establish if the functional properties of bulk tank milk were affected by storage conditions a range of milk compositional parameters were measured, including gross composition and quantification of nitrogen compounds, casein fractions, free amino acids, and Ca and P contents. The HCT, titratable acidity, and RCT of bulk tank milk samples were also assessed.

Likewise, there was no higher at 6°C than at 2°C. During 96 h of storage, the concentrations difference in TBC of milk stored at 4°C between 0 (2,512 cfu/mL) of some free amino acids (glutamic acid, lysine, and arginine) and 96 h (4,786 cfu/mL).Therefore the average TBC of bulk tank increased, which may indicate proteolytic activity during storage. milk was less than 5,000 cfu/mL when milk was stored at either Thus, this study suggests that blended milk can be stored for up 2°C or 4°C for up to 96 h. to 96 h at temperatures between 2°C and 6°C with little effect The European Union imposes a regulatory limit on bulk tank milk of <100,000 TBC cfu/mL (geometric average), whereas some on its composition or functional properties.

In bulk tank milk samples, a greater incidence of SRC was observed in the autumn (20%) compared with the summer (3%), corresponding with cows being partially housed indoors. Thus, it is suggested that bulk tank milk with frequent additions of fresh milk with minimal bacterial contamination can be stored for up to 96 h at temperatures ≤4°C without considerable increases in TBC or psychrotrophic bacteria.
FUNCTIONAL PROPERTIES OF MILK Between 0 and 96 h, minimal deterioration was observed in functional properties (rennet coagulation time, curd firmness, and heat stability), which was most likely due to the dissociation of βcasein from the casein micelle, which can be reversed upon pasteurization.

This change in product type used for bulk tank cleaning is a further step to minimize potential residues from chlorine in milk.

An additional manual rinse may be necessary in these situations. (v) Particularly, with older tanks water solenoids and drain valves need to be checked regularly as poor functioning during wash cycles can result in insufficient amounts of detergent or water being used, resulting in inadequate cleaning and likelihood of increased bacterial levels.

(vii) Maintaining a clean milk outlet is also an important as all milk passes through this point at collection time. (viii) Regular visual inspection of tank surfaces for any biofilm or milk stains should be carried out after cleaning is completed, using a torch.
FUTURE RESEARCH ON MILK COOLING Research trials are on-going investigating the effect of cooling rates on the microbial quality of milk and the energy requirements to achieve top quality milk. Different pre-cooling protocols such as the use of single or double stage cooling and storage temperature setting can also impact on the farm energy consumption and is being investigated.
KEY MESSAGE: It is important to emphasize the importance of maintaining clean milking equipment and good hygiene during milking to minimize bacterial contamination of milk entering the bulk tank milk. The results of this study indicate that when the initial TBC of milk was low and milk was stored at temperatures ≤4°C, TBC levels less than 5,000 cfu/mL were achievable in milk up to 96 h and the functional properties of milk were maintained.

ANIMAL HEALTH
BOVINE RESPIRATORY DISEASE IN DAIRY HEIFERS A recent Teagasc study estimated the cost of rearing replacement heifers in Ireland at approximately €1500. Inadequacies in management of calf health on many farms are adding to the already significant cost of heifer rearing as well as reducing the lifetime potential of those heifers, according to Joanne Cregg, MSD Animal Health, Technical advisor.
A
ccording to data released from the Department of Agriculture, Food and the Marine (DAFM) veterinary laboratories and AFBI in 2014, bovine respiratory disease (BRD) remains the most common cause of ill health and mortality in young calves from 1–6 months of age (1). BRD is a multifactorial disease, resulting from infection with various viruses, bacteria and parasites. Outbreaks of BRD in dairy heifers are typically initiated by an environmental stressor/s resulting in a weakening of immune mechanisms and allowing colonization of the lung by pathogens. Disease caused by primary pathogens, including viruses such as Bovine Respiratory Syncytial Virus (BRSV) and Parainfluenza- 3 virus (PI–3) and bacteria Table 1. The relative frequency of detection of pathogens in post such as Mannheimia haemolytica or Mycoplasma bovis are common mortem cases diagnosed as respiratory infections of calves of 1 to 5 findings (see Table 1). months of age during 2012 (1).

ANIMAL HEALTH rate that persisted through to first calving. This study also revealed that animals requiring multiple treatments for pneumonia during early life subsequently experienced reductions in milk yield during the first and even the second lactation (a reduction of 5 and 10 % of milk yield in lactation 1 and 2 respectively). Milk fat and protein percentages were also negatively affected in animals with persistent calfhood pneumonia (5). This study illustrates the critical importance of selecting treatments that will minimise the relapse rate for pneumonia in clinically affected calves. Veterinary practitioners should assist farmers in the prompt recognition of clinical signs and educate on the importance of immediate isolation of affected stock in a separate airspace, as well as advising on appropriate treatment protocols for affected stock.
TREATMENT PROTOCOLS Antibiotic therapy is indicated if bacterial infection has been diagnosed or is strongly suspected by the attending veterinary practitioner. Suitable therapeutic classes include cephalosporins, fluoroquinolones, phenicols, tetracyclines and macrolides. Restrictions are already in place on many of these antimicrobial classes in other parts of Europe and Scandinavia. Upcoming EU legislation to combat antimicrobial resistance may lead to further restrictions in this region. With this legislation in place, disease prevention programmes including good management practices and vaccination regimes will become even more vital in the control of BRD. Appropriate use of anti-inflammatories is important to protect the welfare of the animal and to maintain lung health during the course of infection. Anti-inflammatories of the non-steroidal antiinflammatory drug class (NSAID’s), such as flunixin, ketoprofen and meloxicam are most suitable. Specific problems identified on individual farms such as parasite burdens or mineral deficiencies must also be corrected.
CONTROL OF RESPIRATORY DISEASE Due to the multifactorial nature of BRD, reduction of the incidence of disease and associated economic impact is based on a number of control measures. Some important aspects of control are as follows:
The Importance of Colostrum intake Adequate colostrum intake shortly after birth is one of the major factors influencing calf health, survival and even subsequent milk production when the calf reaches adulthood. Failure of passive transfer in new–born heifers is associated with an increased risk of BRD (3). One study has even demonstrated a link between colostrum feeding volumes and subsequent milk yield; calves that received four litres, rather than two litres, of colostrum in the first hour of birth, had approximately a 10% higher milk yield in the first lactation and a 15% higher milk yield in the second lactation (5). It is also suggested that clinical signs of BRD and the number of treatment days required are increased in animals with inadequate colostral immunoglobulins (3). Although significant improvements in colostrum management have occurred in recent years, there are still a large number of calves that do not receive adequate colostrum. According to the 2012 All–island Animal Disease Surveillance Report, approximately 70% of calves sampled did not receive adequate colostrum (1). As the immunity from passive transfer wanes quite quickly for some pathogenic respiratory agents, particularly antibodies against certain bacterial agents like Mannheimia (Pasteurella) spp, it would be prudent to consider vaccination of calves at this
stage to stimulate active immunity.As mixed infections occur frequently, vaccination with a multivalent vaccine, to induce immunity to both common bacterial and viral agents, should be considered on high risk farms.
Housing hygiene and ventilation Adequate ventilation of calf housing can reduce humidity levels and can reduce the build–up of noxious gases, dust and bacterial content in the environment. Control of noxious gases, particularly ammonia, requires the provision of dry bedding and adequate ventilation. If natural ventilation is inadequate then mechanical ventilation should be considered. Assessment of ventilation should be performed in the pens at calf level and not in feed passages where conditions are likely to be different. While air movement is considered vital, excessive air movement or draughts can be detrimental to the health of young stock. Air speeds of greater than 1 m/second should be avoided in calves less than 100kg. Shelter belts, canopies or hutches are often used successfully to create microenvironments for young calves where draughts are an issue. Inappropriate stocking density has also been shown to be a significant contributor to the development of respiratory outbreaks. The minimum recommendations on air space for calves are as follows: 6 m3 up to 6 weeks and 10 m3 up to 12 weeks of age (6). The housing of adult animals in the same airspace should also be avoided as older animals may act as reservoirs of infection for young stock. In housed, young stock provision of dry bedding and adequate drainage away from the pens is important in order to minimise humidity. High humidity is a facilitator in the spread of infectious respiratory agents as it prolongs their life-span in the environment as well as negatively impacting on the thermal capacity of the young animal.
Vaccination The significant morbidity and mortality in dairy heifer calves, particularly in the first six months of life, illustrates the importance of utilising an appropriate vaccination regime to provide sustained protection over the period of risk. Advice regarding vaccination should be tailored to suit individual herds and regions. However, given the current RVL data, consideration should be given to incorporate vaccination against M. haemolytica. Bovipast® RSP

can be used in calves from as early as two weeks of age and provides protection against BRSV, PI–3 as well as M. haemolytica serotypes A1 and A6. There has been an increased interest in the use of vaccination as an aid in the control of IBR on Irish farms. Live BoHV–1 vaccines have been shown to induce early immunity against infection. Protection in seronegative animals, for example, can be induced as early as 4 days after intranasal administration and 14 days after intramuscular administration of Bovilis® IBR marker live. Intranasal
Many Irish dairy farms have increased animal numbers in recent years. As herd sizes increase, the continuous influx of susceptible or carrier animals promote the on-going circulation of IBR virus. BoHV–1 vaccination of young-stock should therefore be considered. In order to make an informed decision on the most suitable control measures and the feasibility of such control measures it is important that producers are made aware of the far reaching effects of this disease complex for dairy heifers. To maintain and improve production and profitability, a greater focus on disease
“Adequate colostrum intake shortly after birth is one of the major factors influencing calf health, survival and even subsequent milk production when the calf reaches adulthood. Failure of passive transfer in new–born heifers is associated with an increased risk of BRD” vaccination with Bovilis® IBR Marker Live can be administered to calves from 2 weeks of age or can be administered on the same day as Bovipast® RSP in calves over 3 weeks of age. Revaccination occurring at 3–4 months can be administered either intranasally or intramuscularly and continued at six monthly intervals as required.
prevention and management in calf rearing enterprises is warranted, particularly if certain classes or modalities of antibiotic use become restricted. Without doubt, heifer rearing is complex and challenging. However, efforts to minimise disease and calf losses can be rewarding for both the producer and the veterinary practitioner. 1.

TAX PLANNING ISSUES: You require considering the following taxes when planning capital expenditure on buildings: 1. Value Added Tax(VAT) 2. Income Tax, 3. Relevant Contracts Tax 4. Capital Repayment Trap
VALUE ADDED TAX (VAT) Vat Registered Farmers If you are a VAT Registered Farmer you can reclaim any VAT payable by you on capital work in the normal way on your VAT return which will either reduce the VAT you owe for that period or entitle you to a refund for the period. Recommendations Claim the VAT as it is being invoiced to you rather than waiting for the job to be finished. This will help your cash flow and also avoid delays arising from Revenue queries that commonly arise if a relatively large claim is made. Remember, it is the invoice date that determines the VAT taxable period in which a refund can be claimed, not the date you pay the Building Contractor/Supplier.
Example:
Cost of Building VAT @ 13.5% Amount Invoiced By Contractor
€50,000 €6,750 €56,750
DEDUCT: VAT Refund Grant(60%) Total Deduction
€6,750 €30,000 (€36,750)
Capital Allowances Claimable

This will be claimed as follows: €3,000 for first 6 years and €2,000 in year 7.The value of these allowances by way of actual tax saved depends on the marginal tax rate of the individual farmer.

VAT Unregistered Farmers are entitled to reclaim This tax will not apply to many farmers but where it does apply VAT incurred on building and land improvements and also on the farmer is obliged to comply with the rules and in most cases deduct certain items of fixed plant such as Bulk Tanks, Milking Facilities, tax from payments to the building contractor. etc, subject to a time limit of 4 years.

DAIRY COW NUTRITION
FEEDING THE SPRING CALVING DAIRY COW A major drop in protein % and/or low milk protein can be an early warning that cows are underfed, writes Valerie Hobson, Animal Nutritionist, Quinns of Baltinglass Ltd.
U
ndoubtedly grazed grass is our most cost effective feed on Irish farms and it should be maximised, however it must be recognized that grazing grass diets will only support approximately 19 – 20 litres of milk.Therefore, in higher yielding herds grazed grass must be supplemented to avoid a negative energy balance in the dairy herd which carries huge herd issues long-term. The main objective in feeding cows is to meet the energy requirements of the cow as efficiently as possible. If total energy intake is reduced at any stage during lactation milk proteins drops. A major drop in protein % and/or low milk protein can be an early warning that cows are underfed and corrective action should be taken quickly to avoid subsequent fertility issues.
conditions are poor, is necessary and cost effective in the long run.As well as an increase in milk yield it is a guaranteed way of supplying magnesium in the diet and other essential mineral and vitamins that are essential for herd health and fertility.A simple rule of thumb when deciding on concentrate supplementation should be (Milk yield – 20) x 0.50 = Kg concentrate fed Recommended concentrate feeding level for spring calving herds peaking at 28Litres (2Kgs Solids)
THERE ARE A NUMBER OF POTENTIAL REASONS WHY COWS MAY BE UNDERFED IN EARLY LACTATION INCLUDING: • Feeding poor quality silage which has a low DMD value and poor UFL value • Overestimation of Grass intakes in early lactation – poor grass growth or perhaps poor grazing conditions (wet paddocks) contribute to over estimation • Concentrate supplementation can be reduced too quickly in spring due to over-estimation of grass It’s important to maintain concentrate feeding levels to match grass When it comes to feeding high producing dairy cows at grass the growth.

DAIRY COW NUTRITION
EARLY LACTATION NUTRITION ENERGY Underfeeding cows is unfortunately an issue post calving especially spring calved cows and as previously mentioned, cows quickly go in to what’s known as negative energy balance. What are the main reasons for excessive negative energy balance? 1) Over conditioned cows at calving – these cows tend to have poor feed intakes post calving 2) Under–Feeding compared to energy output a. Heat stress reduces feed intakes b. Management – adequate feed space, grass allocation, fresh water etc. c. Diet Quality d. Climatic conditions 3) Animals Health – general poor health reduces feed intakes, issues can include a. Lameness b. Ruminal acidosis c. Metritis The most important energy value of ruminant feed is the UFL value, 1 UFL is equivalent of 1kg of air dried barley. Energy is required for: • Maintenance • Milk production • Body weight gain • Pregnancy
PROTEIN Energy is the main cornerstone in nutrition; however protein does have a major part to play but it tends not to be underfed as much as energy.When we look at balancing protein in the diet now we look at the PDI system (Protein digested in the Intestine) high quality perennial ryegrass-based swards are likely to contain a high crude protein and PDIN con¬centration, which will increase blood urea nitrogen levels. Furthermore high protein diets would seem to partition nutrients towards milk production at the expense of energy balance. Recent research carried out at Lyons Estate demonstrated that concentrate type had a significant positive impact on metabolic status in early lactation dairy cows at grass. In this study, grazing cows fed 6kg of a 14% pro¬tein compound based on maize grain had significantly reduced blood urea nitrogen and beta hydroxy butyrate in comparison to cows fed 6kg of an 18% protein compound based on barley.
“Energy is the golden ticket to a successful grazing season – so make sure your cows are being fed enough to avoid energy deficits which can lead to a string of problems long term” WITHOUT GETTING INTO TOO MANY CALCULATIONS AND TO INSTEAD DO A SIMPLE SUMMARY:
A 14% Crude protein concentrate should be sufficient when cows are fully out at grass and when working on CP basis it’s ideal to aim for the overall crude protein of the diet to be a maximum of 15% of DM.

FARM DESIGN
THE IMPORTANCE OF WELL-DESIGNED FARM ROADWAYS The milking process really starts when the cows leave the paddock. The benefits of a well–built and properly maintained farm roadway system are numerous, by Tom Ryan, Teagasc.
Don't place water troughs at gateways as cows will slow up and be distracted. This is not the shortest distance to water in the paddock, so more soil damage and grass smearing will occur while going to and fro for water. Water troughs should be level. The pipe size here appears inadequate too. The gateway surface is good.
A
well–designed, carefully built and properly maintained farm roadway system has many benefits, including, less lameness, less mastitis and better general animal health, faster and easier stock movement, cleaner cows and milk, less roadway maintenance and more efficient paddock access.
COW BEHAVIOR
Cows like to walk with their heads down so they can see where to put their front feet.The hind foot is also placed on ground that the cow has seen.When cows cannot place their feet safely they will slow down. It could be because the roadway surface is poor or because they are being forced to move on from behind. If forced to move on from behind ASSESSING ROADWAY CONDITION cows become bunched and they lift up their heads and shorten their stride. Take a quick look at the condition of your farm roadways for Now they cannot see where to put their front feet and they lose control defects that may be causing problems. These defects can include, of where to place their hind feet. Given time a cow that is left to move potholes, a roadway that is level or almost level, wheel track along quietly will seldom misplace a foot, even on a poor surface. depressions, a raised hump of soil under the fence at either side Cows have an average walking speed of 2–3 km per hour (0.6 and cow tracks made between the fence and the roadway or on to 0.8 m per second). On a good farm roadway they can walk at speeds over 4 km per hour (up to 1.2m per second). the roadway. There is a social hierarchy and dominance within the herd. Cows Problems are caused by; pebbles and loose stones on the surface, a bumpy surface with secure stones, lodged/trapped water on the like to stick to their social groups as they walk along to the parlour. surface, very dirty section near the farmyard, and a roadway level Furthermore cows don’t like too much physical contact with other with or lower than the field. The reasons for these defects are many cows as they walk along. When dominant cows slow or stop, the but may be due to flawed construction methods, unsuitable materials rest of the herd will do likewise.

FARM DESIGN
ROADWAY WIDTH The width of roadways depends on the number of cows in the herd. Typical widths of 3.7m to 5m are suggested for herds up to 150 cows with wider roadways needed for bigger herds. A rule of thumb is an extra 0.5m wide for each extra 100 cows in the herd. The fence should be positioned about 0.5m (20 inches) from the edge of the roadway. This will allow cows to utilise the full width of the roadway while at the same time prevent them from walking along the grass margin. A cow track in the grass margin usually means that the fence is too far out and the surface of the roadway is likely to be poor also. The length of the roadway required will depend on the size and general layout of the farm. On farms with heavy soils a more intensive roadway system makes grazing management easier. The intensity or land area devoted to farm roadways ranges from 1–2% of the grazing area. Most paddock systems aim to have a roadway intensity of between 1.2–1.5% of the grazing area.
LAMENESS The surface of the roadway has a big influence on the level of lameness in the herd. The surface needs to be smooth, fine and strong enough to support animals but with a little give in it also. Ideally, the footprints from the cows should be visible across the roadway, but not so much to damage the surface when the weather is wet. Rough surfaces with protruding stones, loose gravel or pebbles (either sharp or round) lying on the surface are a major lameness factor. Moorepark research on 14 commercial dairy farms found that on average between 12 and 16 cows per 100 became lame in a six month period (either Jan–Jun or July–December). On individual farms the figure could be as high as 31 cows per 100 during any six month period. White line disease was the most common cause of lameness followed by sole ulceration. Poor maintenance of roads with little use of top dressing with fine material increased the incidence of lameness. Thus, prevention of lameness at pasture must entail maintaining roads in good condition. The presence of concrete roadways on farms increased the incidence of lameness. Therefore, if concrete roads are used for cows, care must be taken to ensure; that the junction between the concrete and the roadway is maintained in good condition, that the concrete is kept free of small stones, and run–off from the concrete should be diverted away from the roadway. A kerb or nib wall, close to the end of the concrete where it meets the roadway may be useful. If the kerb is a bit back from the edge of the concrete (about

from the collecting yard. Suitable arrangements must be made for collecting effluent/washings from the soiled yards and the drainage away of rainfall from the roadway. Deepening the fine surface layer and ensuring good drainage in the stretch of roadway near the collecting yard will mean cleaner cows, less lameness and lower cell counts.
ROADWAY CONSTRUCTION New farm roadways must be laid in good weather when soil conditions are dry. This is primarily to ensure that the roadway material does not mix or get pressed into soft soil. Ideally remove a thin layer of topsoil before placing the roadway material. Topsoil contains pores, organic matter, is generally weak and is likely to deflect and shear under load. Be careful not to remove too much topsoil as the depth of the roadway will have to be

Typical widths of 3.7m to 5m are suggested for herds up to 150 cows with wider roadways needed for bigger herds” 0.5m), there will be less wear and tear on the roadway where the two meet. Regular brushing/cleaning of the concrete is required. Holding cows for long periods on concrete before and after milking should be avoided. A kerb is also recommended between the roadway and the entrance to the collecting yard. This will force cows to lift their feet dropping off stones before the entrance. The kerb also prevents soiled water from the collecting yard running onto the roadway or rainfall run–off from the roadway flowing onto the collecting yard. The gradients in this area could be in four different directions depending on the lie of the land, the way it was planned or built, etc. The collecting yard could be sloping to or away from the parlour and the farm roadway could be sloping to or away
increased to bring the roadway surface above field level. If too much soil is removed the finished roadway may end up being too low. The finished level of the roadway must be above the level of the field, otherwise drainage will be onto the roadway instead of off it. A wide variety of locally sourced materials may be used as the main road material. If this material is available on the farm, so much the better. However, the cost of using it should be weighed up against the cost purchased material. Compact with a vibrating road roller before the surface layer is spread. Compaction interlocks the material to give a stronger roadway and helps prevent loose stones from mixing with the surface layer.

A geotextile suitable for farm roadways costs about 75 cent per SURFACE LAYER The roadway should be completed with about 50–75m (2–3 square metre. inches) of a fine material on the surface.

strict control over the depth and width of the roadway, in line with needs and good construction practice, is essential. Farm roadway costs range between €4 and €7.5 per square metre. Calculate costs in advance and monitor progress. This will avoid surprises and cost overruns. VAT is refundable on new farm roadways but not on repairs.
COW TRACKS Cow tracks can be installed as extra roadways, as spur roadways off normal wider roadways or at the end of the main farm roadway. Water trapped on the roadway lodges at low points. The photograph shows the most vulnerable first 100m of this farm roadway. The cows are following tracks due to a less than perfect surface.

They are generally only suitable for short runs. They are useful for getting access to out of the way paddocks, to silage ground and making grazing management easier early and late in the season. A depth of about 150mm of material is laid on the surface of the ground. This should be compacted and topped off with a fine surface layer and the surface layer should be compacted also. The width can range between 1.8m and 2.5m; the wider width is preferable. Costs range from €8 – €11 per metre run.
SOME KEY POINTS • Put in two gateways to paddocks to reduce gateway wear and tear • Do not site water troughs on farm roadways or near paddock gateways • Carry out regular roadway repairs. Aim to maintain the surface layer • Avoid sharp bends; have swept bends at corners and T junctions • Critically watch the cow movement and remove restrictions and distractions to cow–flow • Consider removing trees that shade the roadway causing dirty wet surfaces • Get cows to enter collecting yards towards the rear. This lines–up the cows for milking makes it easier for them to adjust their social order for milking • Keep pebbles and stones off concrete yards/roadways • If stones on the collecting yard are a problem consider installing a kerb at the roadway yard junction and an extra depth of fine surface material on the lead–in roadway • Allow cows to move along roadways at their own pace to minimise lameness. This also keeps the cows calm • Slow down with farm machinery and keep tractor and heavy machinery use on roadways to a minimum • If cows slow down on a farm roadway they do so for a reason • If the surface is poor cows will take longer to walk along it • Repair potholes in good time and with fine material

C
alor is one of Ireland’s longest established energy providers supplying energy solutions to thousands of agriculture and business customers nationwide. 2017 is a significant landmark for Calor as they celebrate 80 years of supplying gas in Ireland. This milestone is being marked with the roll–out of a new design for the Calor brand and later this year Calor will launch their new renewable energy, Calor BioLPG. Over the last few years Calor has been working with many dairy farmers around Ireland to design systems that reduce costs and work for the farm enterprise.As one of the most important considerations on a dairy farm is hygiene, large quantities of boiling water are required each day to wash milk lines and bulk milk storage tanks, ensuring hygiene and controlling the Total Bacteria Count (TBC) of milk. Calor LPG-powered instant water heaters provide an ideal solution to meet this need for dairy farmers.They produce a reliable, instant and infinite hot water supply on demand, and minimise the need for chemical detergent use on dairy farms.The Calor system in particular is unique in that it can meet a need on some farms for instant hot water at 85°C. Andrew Claxton converted his farm in Stradbally to Calor Gas water heaters a couple of years ago and more recently has installed the same system in a dairy farm in New Ross; “The Calor instant water heaters have been a great benefit to our dairy business. It’s a much more efficient system for us to heat the water we need for plant and bulk tank washing. We have all the hot water we

need at any time, day or night and importantly it’s at the right temperature to ensure we maintain the hygiene level we need. We’ve definitely made savings since changing to gas.” Origin Green and the Sustainable Dairy Scheme are placing ever greater focus on improving the environmental performance of Irish farms. The Calor LPG solution also delivers in terms of environmental sustainability. As water is heated only when required, hot water storage costs are eliminated. Calor’s telemetry system also ensures that you will never run short on gas, as a gauge continuously monitors gas levels. When you need a top-up, a transmitter sends a signal via GSM technology, and your local Calor depot will schedule a fuel delivery at a time convenient for you. Calor Gas is part of SHV Energy - the largest dedicated global LPG distributor. Further information on Calor is available at www.calorgas.ie.

ipetane uniquely equalises and stabilises the carbon chains in all standard fuel. This enables all of the incoming 21 Units of Oxygen in the air, to attach and burn the carbon chains, thereby enabling more complete combustion. Dipetane is a unique product. It is the only pre-combustion fuel treatment world-wide that significantly reduces the Green House Gas problems associated with all standard fuels. Dipetane reduces fuel usage by up to 10%. Dipetane reduces NOx by up to 30%. Dipetane reduces CO2 by up to 15%. Dipetane protects Injectors against Low Sulphur Fuels due to greater lubricity. Dipetane keeps EGR’s, DPF’s and Catalytic Converters clean due to more complete combustion of Carbon. Dipetane helps to burn the lower Carbon Bio-Fuels more completely. Dipetane has a Cold Pour Point of Minus -34c°. Dipetane is 100% Hydro-Carbon. There is nothing in Dipetane that is not already in your fuel. It cannot change the spec of your fuel which remains within the EN590 Fuel Specification. Therefore all warranties for your vehicle remain intact. Dipetane is not a ‘Fuel Additive’. Fuel Additives poorly address the problem of un-burnt carbon after combustion. Additives do very little to help the initial burning of the expensive Carbon. You will notice the lists of toxic and hazardous ingredients in these fuel additives. Dipetane contains no additives whatsoever. Dipetane is a single product suitable for use in all fuels, engines and boilers. Dipetane is used at a ratio of 1:200 in all fuels. 1 Litre of Dipetane treats 200 litres of Fuel.

Over the last 10 years 2007 to 2016, the vast majority of these fatal accidents involved Tractor and Machinery use (48%), followed by Livestock 13% and Falls from Height & Falling Objects both leading to 10% of deaths in agriculture. These figures which all represent dreadful personal tragedies tell us where we must focus our efforts. The HSA will run 3 campaigns this year, in March on Livestock Safety, May on Tractors and Machinery and November on Falls from Height & Falling Objects.

normally quiet cows can become aggressive in and around the time of calving. The casual approach by many farmers of entering pens with freshly calved cows without any means of protection or escape must cease. No chances or shortcuts should be taken with the calving cow, stay alert, have an escape plan and carry a stick. Calving gates which have an openable inner gate can reduce risks particularly during a delivery by caesarean. The recent farm safety scheme offered by the Department of Agriculture (specification S138) sets out the Minimum Specification for Grant–aided Calving Gates and Mobile Cattle Crushes. A strong light source, good underfoot conditions and keeping dogs away are also important. For more information and safety resources click on the following website www.hsa.ie
