Sugar in the ruminant diet Carbohydrates are the main source of energy for rumen microorganisms and consequently, are also indirectly the main source of energy for the host ruminant animal. Rumen microorganisms utilise carbohydrates and produce volatile fatty acids, which are then absorbed by the ruminant animal as a form of energy.

carbohydrate), sugar is used up much faster by microorganisms and hence disappears from the rumen at a much faster rate. About 90 percent of the dry matter in molasses (which is high in sugar) will be fermented in the first hour following consumption, compared to about 20 percent of the dry matter of wheat in the same timeframe.

Adding sugar, for example from molasses (65 percent of dry matter is sugar) or carrots (30 percent of dry matter is sugar) to a silage based total mixed ration can help to increase dry matter intake. Anything we can do to improve the functionality of rumen microorganisms will be beneficial in terms of production responses, due to improved efficiency of digestion. Sugar is present in pasture but in varying levels depending on the forage type and even the time of the day or season. Sugar levels rise in grass over the course of a day, due to increased photosynthetic activity of the plant during daylight hours. Similarly, grass tends to have a higher sugar content in spring compared to winter due to increased daylight hours and warmer weather increasing rates of photosynthesis. In a cold, wet spring or extended overcast periods, supplementing with sugar at that time will complement the low sugar grass

and may improve milk production and milk protein percentage, which could also have repercussions on fertility. Conserved feeds such as silage tend to have low sugar content, as the sugar that was in the forage at the time of harvesting has been used up by microorganisms during the ensiling process. Feeds such as molasses are high in sugar and can be useful to add to a ruminant’s diet if sugar is lacking, however they must be used with caution, as too much sugar entering the rumen at once can cause a decrease in rumen pH due to the rapidly fermenting nature of the sugar and acidosis can be a risk. Slug feeding of high sugar feeds is therefore not recommended and it is better to spread out supplementation of sugars over the course of a day to provide rumen microorganisms with a more levelled out supply of readily fermentable material. This is where starch can become important, as starchy feeds such as grain are naturally slower degrading feeds, so will provide fermentable energy to microorganisms in a more slow release way compared to sugar. Animals like sugar and they tend to select feeds higher in sugar if given the chance, due to the inherent drive to consume feeds that are higher in energy. By adding molasses to feeds, we can make them more appealing to animals. For further information, contact your Farmlands Technical Field Officer or the friendly team at your local Farmlands store.

My lifestyle block – Cheryl Ford and Geoff Chapman A productive 8 hectare block in Canterbury is allowing a couple of dairy cow enthusiasts to keep doing what they enjoy and generate some income. New Zealand Ayrshire show judge Cheryl Ford and her partner Geoff Chapman currently milk eight Ayrshire cows, including four first-time calvers but they still averaged 33 litres per cow at their peak in November last year. The Leeston herd is fully milk recorded with LIC – heifers are shown and sold at stud sales to farmers who value the breed’s milk production, temperament and ability to hold condition through the winter. Based on the milk recording, last season five cows averaged 7,025 litres each over 278 day lactations at 4.97 percent butterfat and 3.45 percent protein. This year their milk has helped raise 80 Friesian calves and 10 crossbred beefies. The cows are milked in the farm’s original 4-aside milking shed and calves are reared in what was

Having two very different feeds available allows Cheryl to respond to changing pasture quality and individual cow performance very quickly. Both soya bean meal and soy hulls contain low levels of starch, so levels can be adjusted rapidly when required without fear of acidosis. Pre-calving pellets have helped the cows through calving and helped them to go straight onto the milking ration. Cheryl and Geoff have made calf rearing work around their building and paddocks and are not afraid to do things differently to the norm. The Ayrshires continue to milk well into the autumn, which allows autumn born calves to be reared in addition to the main spring group. Calves are given hard feed through the winter – last winter they had soy hulls every day – to keep them growing on, so that beefies can be finished before their second winter and replacements are well grown.

Increasing muscle and topline in performance horses Topline is a common term among most performance horse owners and riders – it refers to the degree of muscle definition along the horse’s neck, back and hind end. Depending on the discipline, the amount of topline holds varying degrees of importance, however achieving topline in all competing horses is one of the main goals. Nutrition and work are the two most important contributing factors to building topline and the numerous aspects of feeding and exercise management need to be considered carefully in order to achieve improvements in muscle definition in this area. Often poor muscle definition can simply mean the horse is lacking in overall condition and requires more calories to gain weight. Increasing forage through additional hay or fibre products can help and lucerne hays or chaff products generally contain higher energy levels than grass or meadow forage types. Increasing hard feed and grain, or selecting a higher energy feed type can also assist in providing the additional calories required for weight gain. Fat in the form of oil or stabilised rice bran such as NRM Equi-Jewel plays an important role in conditioning and are great options for horses that have low tolerances to grains and can become hyperactive or experience muscle problems when excess grain is consumed. Arguably the most important nutrient for muscle development is protein. Amino acids, which make up proteins, are the basic building blocks of muscle. Horses must consume at least nine

THE FARMLANDER

essential amino acids in their diets and the remainder they can make on their own. Deficiencies in protein and certain amino acids can lead to a dull coat, brittle hooves and a rapid decline in muscle definition. The National Research Council recommends that minimum protein requirements for an average 500kg horse in moderate work are 768g per day, which can generally be met easily

High fat supplements such as NRM Equi-Jewel are often more successful in improving condition and topline, especially when combined with work.

through feeding a diet of high quality forage and the correct amount of a balanced feed formulated for the work the horse is doing. Additional protein can be included in the diet through feeding a more concentrated feed if extra calories are needed as well, or topping up levels with a high-protein supplement like a balancer pellet, which is fed in small amounts and adds very little calories to the diet. While it is essential to meet protein requirements on a daily basis, it is important to consider that excess protein will not be utilised in the production of more muscle. Any protein not utilised is excreted through urine and providing protein in excess of requirements for an extended time period can increase water consumption and cause a smell of ammonia in the horse’s urine as the protein is excreted. When attempting to build topline, it is important to be cautious of the various nutritional supplements making claims regarding muscle building properties. Many will contain high levels of protein, which may not be necessary if the horse’s current diet contains sufficient amounts.

Balanced nutrient intakes support animal health and welfare Although there are some differences in the ingredients humans and animals consume, ensuring nutrient intake is balanced is just as important for animals as it is for humans. And in the same way that the nutrient requirements of an adult woman differ from those of a teenage boy or an energetic toddler, the nutrient requirements of poultry vary depending on their age, breed, sex and stage of their productive cycle. Like children, who should be given treats in moderation, it is particularly important that young growing poultry consume a balanced diet that provides sufficient protein, energy, vitamins and minerals to support rapid early growth. A specially designed Chick Starter Crumble is ideal for this purpose. In the same way a pregnant woman requires a balanced diet with good quality protein to support the growth of her baby, a laying hen requires good quality protein to support egg production. When properly balanced, vegetable protein sources such as soybean and canola meal provide an excellent source of high quality protein, which can be used for egg production. One of the key differences between laying hens, pregnant women and most other poultry is their high requirement for calcium, which is used in the production of egg shells. Grains, oilseed meals and other plant material is generally too low in calcium to meet the demands of a

Weed control options to increase productivity of autumn sown pasture In today’s farming environment, the short timeframe between pasture spray-out and drilling gives weeds the maximum opportunity to germinate and compete in new pasture. If this weed burden is not managed early, the time to first grazing can be delayed, compromising quality and quantity, along with the potential longevity of pasture. New pasture often presents a wide spectrum of weeds, so more than one herbicide may offer the best results. With a proven track record over many years, Dow AgroSciences’ herbicides play an important role in successful new pasture establishment. Preside™ herbicide controls many of the common weeds encountered in newly sown young pasture, including spurrey, shepherd’s purse, black nightshade, amaranthus, fathen, buttercup, sorrel, oxeye daisy, stinking mayweed and field chickweed (a smothering weed that can quickly choke clovers and grasses in autumn). If thistles are present, Select™ herbicide can be added to Preside to broaden the spectrum of weeds controlled. Preside and Select herbicides are equally safe to both grass and clovers, so there is no check to rapid pasture establishment, even when they are used in combination. Uptake™ crop oil must always be added to Preside applications, even when tank-mixing with Select. Timing with both of the above herbicides is critical to achieve maximum results. Monitor newly sown

THE FARMLANDER

paddocks regularly. Application should be considered as soon as clovers are at the two true leaf stage and there is 50 percent ground cover (from foliage of pasture plants and weeds together). By this time seedling weeds will be readily identifiable, enabling you to choose the best herbicide or herbicide combination to use. As young seedlings, weeds will be at the ideal stage for maximum control and will be controlled before they compete with the new pasture. Preside is available in two pack options – the 256g pack of Preside contains 16 convenient water soluble sachets that are easy to mix and measure into the spray tank. A 256g pack will treat between 4 and 8.5 hectares, depending on rates required. A larger 500g pack is also available for contractors and larger users, which is loose packed and comes with a convenient measuring cylinder. Select is available in convenient 20L packs, which will treat 5 hectares.

Don’t leave your weed control measures to chance – when you weigh up the total cost of pasture renewal, early effective weed control is cheap and effective insurance.

Proven, productive and persistent ryegrass Fit for purpose and value are all important parameters for pastures in today’s modern farming environment. Together, they are key considerations when it comes to growing grass and feeding animals. In today’s farming system we expect a lot from our pastures. With increased stocking rates, improved genetic merit in the national dairy herd and an increasing reliance on home grown feed, it’s no surprise that our pastures need to be robust feeding platforms. The ryegrass/white clover relationship needs to be carefully integrated and advice from your local Farmlands Technical Field Officer about endophyte and genetic choice is paramount. Logan Quinn, who contract milks 215 cows on a spring calving platform not far from Paeroa on the Hauraki Plains, has been fast to adopt new technology and a large part of his 78 hectare platform is now made up of ONE50 perennial ryegrass.

That financial advantage between ONE50 with AR1 or AR37 could be as much as $402.00/hectare (Upper North Island). ONE50 is a diploid cultivar made up of a cross of elite genetics including north-west Spanish material and plants screened in Northland and has very good persistence and tolerance to dry and hot summers. With a late heading date (+20 days), ONE50 AR37 is ideal for farm systems where high production and improved late spring feed quality are important, providing excellent spring production and summer leafiness. It also has a high tolerance to rust, which is important in regions prone to ryegrass rust. ONE50 AR37 is the late-heading ryegrass and endophyte of choice for many farmers.

Milking 960 cows through a rotary shed, they know the importance of home grown feed and do all they can to maximise it. Since the drought of 2008, Andrew and Rebecca have done a lot of pasture renewal and have used a number of different species and ryegrass options. When they were planting perennial ryegrass alone on lighter soils, the plants just struggled in the dry and never produced enough dry matter when they needed the feed.

Effective removal of persistent weeds in the pasture renewal cycle Annual ryegrass in the pasture renewal cycle creates a great opportunity for farmers to clean up dirty paddocks where deep rooted perennial weeds have become seemingly impossible to control. A proven strategy for astute farmers is to build a cropping programme around pasture renewal. The decision to renew a pasture is triggered when pasture production drops significantly, usually as a result of heavy infestations of deep rooted perennial weeds that have been unsuccessfully controlled by “clover friendly” herbicides. The economic benefit of spraying out underperforming pastures and replacing them with new, high performing varieties is usually far greater than the decision to persist with an old, underperforming pasture. The cropping phase of a pasture renewal programme creates a rare opportunity to achieve long-term control of hard to kill weeds such as Californian thistle, dock and in more recent years, oxeye daisy – which are often not well controlled by “clover safe” pasture herbicides, so it’s a great opportunity to get on top of them. However, until recently there have been limited options to gain reliable control of these deep rooted perennial weeds

While glyphosate is very effective against grasses, broadleaf weeds are not so well controlled by glyphosate alone. Various broadleaf herbicides and adjuvants are often added to glyphosate to improve broadleaf weed control but deep rooted perennial broadleaf weeds such as docks, Californian thistle and oxeye daisy often re-grow because their root systems are not totally killed. As a consequence while control might look good 2 or 3 weeks after a spray application, a short time later these weeds re-emerge having re-grown from live root remnants. If these deep rooted perennial broadleaf weeds are not well controlled in the cropping phase of the pasture renewal cycle they quickly become an issue and very little is gained.

If sowing a straight annual ryegrass this autumn, T-Max herbicide mixed with glyphosate at spray-out is the most effective way to break the perennial broadleaf weed cycle and get high level control of these hard to kill weeds prior to sowing. While ryegrass can be sown straight after T-Max in a spray-out application, it is recommended to wait at least 6 months before re-establishing clover. Tank mixing T-Max with glyphosate prior to sowing annual grass in autumn provides a perfect buffer to ensure good clover establishment the following season.

Two ways to improve your autumn spray-out The stage is set for autumn pasture sowing but many farmers still don’t get the best results and you might be one of them. The good news? It’s easy to fix this situation by adopting some agronomically sound principles. That’s the advice from veteran pastoral farming specialist Graeme Dale, who says preventing two mistakes commonly made on-farm at this time of year can quickly pay off. “The first thing is to check if you need a companion herbicide with your glyphosate for spraying out prior to sowing. The second is to use the right rates of glyphosate. If you tick those boxes, you will have avoided two very typical pitfalls in autumn sowing.” Graeme, the Waikato, King Country and Taranaki Territory Manager for Nufarm, says tank mixing companion herbicides like Nail® EC with WeedMaster® TS540 provides control of more weeds before sowing new pasture than if they use glyphosate alone. “There are some weeds that the glyphosate molecule does not control, which you definitely do not want in your new grass. They’re not always present but if you miss them now, you miss your last chance to get rid of them.” This is more important where farmers don’t cultivate before sowing. “Cultivation will hide a multitude of sins!

THE FARMLANDER

In no-till situations there isn’t a set of discs or a plough to hide behind. You’re totally reliant on the spray programme to get rid of all the weeds. Whatever is green in that paddock after sprayout is a weed and it will compete with whatever you plant, so the spray-out has to be 100 percent effective.” Graeme says ex-summer crop paddocks need special attention. Sometimes when these are established in spring, there has been a less than ideal spray-out because of plant back and soil residue considerations. “These paddocks are usually full of weeds in the first place, which is why they were cropped and they may have come through summer with many of those weeds still present, because a lot of them weren’t actively growing when they were sprayed out in the spring.

enough, particularly creeping mallow, seedling storksbill and nettles. Sero™ WG is also useful. In all cases, using the right rate of WeedMaster TS540 is critical, Graeme says. “If the label rate is 3-4L/ha, in a no-till situation always use the maximum rate. Pulse Penetrant is also a must.” For further information, contact your Farmlands Technical Field Officer or the friendly team at your local Farmlands store. Article supplied by Nufarm.

“In autumn, however, you can use a number of companion herbicide options that you can’t use in spring and you can deal with those weeds in a big way.” Graeme says farmers should make no assumptions about paddocks that are going into autumn planted perennial pasture until they’ve checked to identify different weed species. Then it’s a case of selecting the right companion herbicide, if required. Nail EC, for example, provides control of some broadleaf weed species for which glyphosate alone is not always

Remove tough broadleaf weeds before you sow this autumn Good weed control before you sow your autumn pasture is essential to maximise yield and persistency. Unfortunately many opportunities are missed when spraying out old paddocks, as the common thought is “glyphosate will control all the weeds in that paddock”. This is not always true – and the last thing you want to see coming through in your new grass is unwanted weeds. It is important to take the opportunity to remove these difficult weeds before sowing new pasture, as the extra investment is negligible compared to the cost of controlling difficult weeds post-emergence and the subsequent loss of production. So this autumn before establishing new pastures, ensure you add DuPont Granstar® 75DF or Harmony® 50SG to your glyphosate (and penetrant) to

improve the control of unwanted weeds such as old man docks, buttercup, yarrow, thistles, clover and many other broadleaf weeds. To improve broadleaf weed control, it is important to note the following: • Let the paddock freshen up after grazing and ensure there is good leaf area and actively growing plants to maximise uptake. • Leave the paddock for 3 (Granstar) to 7 (Harmony) days after spraying before grazing or cultivation. • Ensure you leave a plant back period of 14 days between spraying out and sowing your new pasture.

Lose less heat, gain more feed energy Maize silage contains a high concentration of starch and sugars. This makes it more prone to heating when the stack or bunker is opened at feed-out time. When silage heats it loses valuable nutrients, which could have been used by the cow to produce milk.

Manage velvetleaf before it becomes a serious problem Farmers are reminded to be vigilant and deal to velvetleaf this summer before it takes a hold. Velvetleaf is an aggressive weed that, within a few years, can completely overrun an area if left uncontrolled. The pest weed entered New Zealand in contaminated fodder beet seed in 2015 and since plants were found in early 2016, the Ministry for Primary Industries (MPI), regional councils and primary sector industry partners, including Farmlands, have been working to help farmers control it. Velvetleaf is a serious cropping weed, potentially affecting many arable crops by competing for nutrients, space and water. MPI’s Response Incident Controller David Yard says the concerning thing about the weed is its potential for spread. “What can be a small problem of a few plants in the first season quickly becomes a much bigger problem in subsequent seasons.

Don’t take chances with autumn pasture establishment Farmlands Senior Technical Field Officer, Bruce Hemingway, has a simple philosophy about seed treatment – “I wouldn’t sell any seed without it”. Based in South Waikato and looking after clients from Tirau down to Taupo, the seasoned Technical Field Officer says no matter what the situation, he never sells bare pasture seed. “I might get one guy a year who says do I really need it? But when you explain it to them, there’s no argument. They don’t want to take a risk they can avoid and enough of them have been stung by insects or other problems in the past to know it can happen.” Bruce says that the cost of seed treatment is minor in the overall scheme of things. “For a start, you’ve got to look at the price of a kg of grass seed over the lifetime of the pasture. It’s pretty cheap for what you get. Seed treatment is just a small percentage of that price. And it costs just the same in paddock

preparation and inputs to sow treated vs untreated seed, so you might as well do it properly.” Bruce says there’s another good reason to use seed treatment – “the more you can do to help the plant, the better for pasture persistence and that includes from underground to emergence to above ground.” Agricote Grass seed treatment includes fungicide and insecticide to protect grass seedlings during the critical phase of early establishment. It is particularly critical in four situations – where pasture renewal is being undertaken via grass to grass sowing, when new pasture seed is being undersown into a run-out pasture, where there is a known history of insect pressure or fungal disease and where conditions can become dry postsowing, because this means seedlings are slow to grow and thus are small and susceptible to attack for a long period. On farms where black beetle and

Argentine stem weevil are known to be a problem, Agricote Grass is an essential precaution. Even if ryegrass seed contains endophyte, such as NEA2, this does not offer full protection until spring, when the grass plants are more mature.

“

Grass seedlings containing endophyte can still be attacked and killed by pests at establishment. Grass seedlings containing endophyte can still be attacked and killed by pests at establishment and Agriseeds, the company behind Agricote, says its field staff sees instances of this every season when seed treatment is not used. Agricote Clover is also recommended for autumn sown pastures.

application for any particular crop.

Soil tests and fertiliser recommendations from your Farmlands Horticulture Technical Advisor are important. Ground spread fertiliser applications should be completed by fruit set.

It is important to monitor bud break

As crops near harvest, it may be useful to consider how management practices might have influenced crops and what post-harvest practices should be considered.

Natural leaf drop is preferential for plant nutrient retention. The energy for new emerging shoots initially comes from reserves stored in winter buds (until leaves develop and commence photosynthesis).

High water content and excessive nitrate levels are the enemy of fruit dry matter. The challenge is to find the balance between crop loading (tray production), canopy vigour and nutrition to maximise returns. Growers should aim for a medium to low vigour canopy with well selected medium sized cane. The canopy should be even and open, allowing good sunlight penetration. Weather and geographical location also play an important part. Fruit dry matter seems to be maximised in seasons with warm springs, moderate rainfall and summers with long sunshine hours. A large leaf area facilitates carbohydrate production. If excessive vegetative growth is minimised, and vines are cropped moderately, fruit taste and dry matter can be maximised. The following is a recently updated summary of management practices related to optimising dry matter in G3 crops: Heavily cropped vines should receive post-harvest foliars, as maintaining leaf quality will support next season’s buds. Post-harvest Psa protection sprays should take precedence, as it’s critical

THE FARMLANDER

Winter canopy pruning should focus on selecting medium sized, evenly spaced cane. Wood selection is very important. An optimum bud count is 25-30 per square metre. Excessive cane tying should be avoided, otherwise later vine management and spring fruit thinning will be required. Ideal cane spacing is 40-45 cm. While growers have the ability to drive high yields, caution is required if yields surpass 15-18,000te/ha, as this may result in higher proportions of small fruit. Conversely, under-cropping may result in lower numbers of large fruit, a limiting of returns and excessive vegetative canopy growth. Hydrogen cyanimide should be applied approximately 20 to 30 days before natural bud break. This provides more uniform bud break, flowering and crop maturity. The timing of hydrogen cyanimide application is important and is influenced by winter chilling hours. Farmlands’ recent introduction of the BreakNSure test kit will better enable determination of winter chill hours and therefore the optimum timing of

and flower bud density. High densities should be thinned before and again after pollination. Pollination is obviously critical to fruit production, so adequate bee numbers and sufficient male flowers are essential. Insufficient male flowers makes artificial pollination essential. Generally, large fruit will have higher dry matter, small fruit will have lower dry matter. A reasonable target is 60 fruit per square metre. Most canopy management should be conducted early to minimise fruit marking and excessive vegetative growth. Significant fruit dry matter can be lost to unnecessary vegetative growth. Three to four rounds of early crush tipping will assist growth containment. It is essential that leaves are kept healthy – they are the carbon collectors. Once again, ensure that canopies aren’t too dense and ensure that light is getting through the canopy. Grass growth in the sward is a good visual indicator of light penetration. Vine growth can be regulated to achieve good dry matter production in several other ways. Nitrogen can be applied in spring, however excessive fertiliser applications should be avoided. Leaf testing should be employed to monitor nutrient status. Foliar products will be of particular assistance in cooler temperatures, or if smaller leaf sizes

are prevalent. A Farmlands Horticulture Technical Advisor can advise on appropriate options. Good levels of leaf calcium are important through pollination, and monitoring through leaf sampling is essential. Healthy calcium levels assist in developing strong cell walls in the fruit.

Eliminate overflowing or empty troughs Garry Beckett, owner of Farm Water Services in Waipawa, primarily installs water systems for sheep and beef farms. In the past he has had trouble with valves not operating properly because they couldn’t handle the pressure, which caused either overflowing or empty troughs – a disaster for any farmer. Garry needed a trough valve he could trust to ensure his customers’ troughs were supplied with the right amount of water at the right time. Thirsty cows and overflowing troughs were not an option. Getting the right balance of pressure and flow was important to Garry and his customers alike, so he was pleased when he came across the Hansen Fastflo trough valve, which could guarantee the balance he was looking for. The Fastflo completely solved the “stuck valve syndrome” problem. “I am very happy with Hansen Fastflo. It’s an excellent ‘go-to’ valve because of its combined ability to adapt to such a wide range of applications in either high or low pressure, long or short arm, top or side entry and with a large range of long or short thread inlet adaptor options to boot,” Garry says.

Troughs – how big, how many? Unrestricted stock access to the correct volumes of clean drinking water is essential in maximising production outcomes. There are a number of factors involved in getting the right volume of water to your stock. These include: • Being able to supply the daily water demand for the farm – is tank storage required? • Delivering the peak flow demand to the troughs – outcome of a welldesigned reticulation system. • Size, shape and number of troughs per paddock. Just as considerable thought and expertise is brought to bear in regard to providing enough stock water, so should the selection of the correct trough/s. Round troughs provide the greatest circumference, enabling the most stock to drink at the trough at any one time. Oblong troughs are suitable for lower peak water demands, i.e. sheep, calves/weaners and can be positioned to suit the paddock’s shape or through a fenceline to supply two paddocks. Troughs shouldn’t be selected upon

the volume of water they can contain. Think of a trough as being a drinking utensil, not a storage device. It’s the job of the well-designed water reticulation system to provide enough water to meet peak demand, not the size of the trough. Using troughs for water storage can adversely affect water quality and palatability, with issues including warm water, algae growth, soil, faecal and fertiliser contamination. Stock will respond better to fresh, clean water every time.

Stock do not drink evenly over a 24 hour period, so reticulation systems are designed around peak demand. For example – a lactating dairy cow requires 70 litres of water per day, in a herd size of 200 plus, a fifth of them drink at any one time, which is 14 litres per hour, per cow.

This behaviour somewhat negates the benefit of having multiple troughs in a paddock, as they will then compete for water at that one trough they have just moved to.
