It is well recognised that broiler uniformity is beneficial for optimal performance on farm. With a better homogeneity the nutrient requirements for the individual birds are less variable and less safety margin is needed to meet the requirements of all birds.

NewS feedworks Coolum Conference 2012
Feedworks held its 2012 Animal Nutrition & Production Systems Conference at Coolum on Queensland’s Sunshine Coast on September 12 to 15. The theme for this popular event was ‘Be it Evolution or Revolution – The only thing that is Constant is Change’. On the evening of September 12, Malcolm Mottram, Managing Partner of Feedworks, welcomed guests and introduced the first speaker, Tony Edwards, BECAN consulting group. The topic ‘40+40 – How change has impacted us and will impact us in the future’ was addressed by Mr Edwards and then Dr Rob van Barneveld. The pair are probably better known as nutritionists for the pork sector but the issues they covered, including shifts in politics, animal welfare improving technology and changes in meat consumption patterns, apply to both the pig and poultry sectors. “In 40 years the population will increase to 9.2 billion and consumer demand will increase as developing countries become more wealthy. “There will be a need to increase food production by between 70 and 100%: demand is increasing by 2% a year but food production is only increasing by 1%,” Mr Edwards explained. Dr van Barneveld stated that without change the future for meat industries could be grim and that current livestock production is based on a philosophy of abundance which is wrong as competition for grain, not only for human consumption but for the folly of ethanol production increasingly squeezes supply. “In the future the more efficient livestock industries like poultry production would make more sense than rearing cattle as grain supply tightens,” he said. “We have to drive change in our industry to ensure livestock make a net contribution to food production,” he said. “We have the overall capacity to meet global food demands and livestock needs to ‘value add’ to food production by converting nutrients that cannot enter the human food chain into valuable protein and energy. “Livestock should not compete for high demand resources as part of the food chain,” Dr van Barneveld added.

“The role and scope of the nutritionist will significantly increase as part of the livestock production cycle,” he concluded. On the September 13 the first speaker was Dr Stuart Wilkinson from the University of Sydney who delivered a paper, ‘Animals eat protein not carbs’. This paper was prepared by Dr Wilkinson and Professor Aaron Cowieson, Director of the Poultry Research foundation at the University of Sydney. Given the current influence on Australia retailer policy by management with experience in the competitive UK market, Dr Partick Garland from UK based Premier Nutrition next delivered an overview of aspects of the UK poultry industry. His paper was entitled ‘Practical Nutrition in a changing environment – UK Perspective.’ “Pressures on UK feed raw material (RM) supply and selection included a 2.5-3 million tonne demand on wheat for ethanol production and retailer restriction on RM selection including nil animal fat, non GM soya (though this is changing), vegetable protein only based diets, reduction in antibiotic use, welfare directed broiler stocking density of 30 kg /m, and the latest initiative – diet formulation to carbon footprint,” Dr Garland revealed. “Major changes in the layer industry from 2010 to 2011 included a drop in free range production of around 12% and a big drop in colony and barn laid (which consumers had difficulty in understanding) of nearly 40%,” he said. “Free range, however retains a significant market presence (50%) where small producers, with typical flock size of 3000 birds, have a big presence in overall production. “Typical codes for free range layer farms are 2500 hens/HA under EU regulation and 2000 birds/HA under the British Lion Code. In 2011 the margin per bird for free range farmers was around seven UK pounds,” he added. “Despite regulation formulated in the EU to ban cage production, 23% of birds here are still housed in conventional cages whereas in the UK growers have abided by new regulation on cages,” Dr Garland said. “In broiler production shortage of available land for farm construction combined with feed pressures and compliance CONTINUED ON PAGE 8 w

NewS v CONTINUED FROM PAGE 4 with planning authority requirements meant that cost of production was going through the roof,” he said. Dr Dave Cadogan, in his paper ‘ The facts and myths of dietary fibre’ delivered a number of key take home messages including, “lignin is not a carbohydrate, pectin is high in fruit and lupin hulls are similar in net energy to wheat.” ‘Animal nutrition within Dupont – applying science to find solutions for some big challenges in the animal protein industry’ was the topic for Dr Andrew Harker, Business Unit Director at DuPont/Danisco Animal Nutrition. The opening statement by Dr Harker that “every day another 150,000 people joined humanity” focused attention on resources in both food and energy. “The big three challenges for his business were, he stated, “food, energy and independence from fossil based fuel”. “DuPont as a global organisation has a turnover of $38 billion and held a clear focus on keeping people and the environment safe in its quest to solve the problems of food and fuel. “Sugar is becoming the ‘new oil’ and corn based ethanol is just a stepping stone into an era of more sustainable biofuels,” he said. On specific products for the poultry industry in the pipeline, Dr Harker mentioned the new Axtra phytase that would help to deliver improved efficiency in poultry diets of a range of grain based diets and raw materials including DDGS. Dr Pierre Cronje is one of those speakers on scientific matters that goes way beyond just delivery of facts and propositions. He weaves a story around his subject and takes his audience on a journey of discovery. His paper was ‘Diabetes research reveals a new mode of action for betaine: implications for the prevention of fatty liver in the poultry and livestock industries.’ Without doubt this issue is of relevance to the poultry industry but also to human health. “Fatty liver is closely associated with diabetes and 1 in 5 of the population in western developed societies suffer from some degree of fatty liver resulting in a fair degree of morality,” he revealed. “In poultry, fatty liver depresses immune competence and is therefore of welfare and economic concern,” he said. In delivering his second paper of the day, ‘Omega 3 fatty acids and their impor-
8
tance in productivity,’ Dr Stuart Wilkinson spoke about the importance of Omega 3 fatty acids in not only intensive livestock production, but human health as well. He revealed that his research had covered some interesting physcological as well as nutritional aspects of fatty acid presence in diets and some possible consequences of the lack of it. In concluding his findings Dr Wilkinson suggested that proportions of n-6:n-3 polyunsaturated fatty acids (PUFA) should be considered, not just the PUFA: SFA (saturated fatty acids) ratio. “Prolonged exposure to diets with a high n-6:n-3 PUFA may be detrimental, and fatty acids have differing physcological roles,” he said. “No recommendations are currently available for either pigs or poultry,” he concluded. On the September 14 in the Monogastric session, Dr Gary Partridge (Technical Services Manager DuPont/ Danisco Animal Nutrition) and Dr Alex Peron (Aspac Technical Services Manager DuPont/Danisco Animal Nutrition) jointly covered their topic, ‘Back to the future in customer solutions from Danisco and DuPont’. They spoke about the new AXTRA product range and ‘the great Betaine debate’, a reference to organic and HCI product alternatives. Dr Peter Scott (Scolexia Pty Ltd) then spoke on ‘Why blending diets on a layer farm just makes ‘cents’. Dr Scott opened his presentation by posing the question, “Do producers realise that the differeence between a 95 gram and a 115 gram intake ration is between $40 to $60 ?” Describing the Feedlogic trial at a purpose built layer farm operated by Scolexia in which there were, “phased ration feeding intended to achieve various desired outcomes,” Dr Scott said. “Key factors revealed during the ‘Feedlogic’ trial included the production of some large eggs but moderately high recovery and medium sized eggs throughout the trial with high recovery levels (97.5%). Also minimal numbers or early lay ‘small eggs’ with overall production of a constant sized egg,” Dr Scott reported. “On the topic of costs saving achieved using the Feedlogic technology there was a 19 cents decrease in feed costs over the period of the study and a 33 cents saving over a full year.

development in mid September, 10 sheds of the first 12 shed unit were complete and occupied, and the final two sheds will be operational by October, according to ProTen CEO Daniel Bryant. About 800 metres away the second unit, also of 12 sheds will be complete by mid March 2013. The sheds, all built by R & DG Sanday, each hold 54,000 birds, are 17m x 160m in size with a floor area of 2720 square metres. They conform to well proven ‘clean skin’ shed design with no exposed trusses, columns or internal bracing. R & DG Sanday also built the 16 sheds for ProTen at its Henderson Farm near Serpentine south of Perth in WA and the combined expertise of both companies has resulted in a shed design that is well managed and delivers high levels of consistent efficiency.
POULTRY DIGEST, August/September 2012
“By using the best available technology and shed design, our Henderson property has been topping the pool for more than two years,” Daniel said. Ron Sanday described some of the other design features that help to deliver reliability and ease of use as well outright performance. “The ‘Dog Box’ area around the cool pads is fabricated from steel and aluminium, not only for strength but by avoiding the use of timber, which can become porous and biosecurity risk is reduced,” he explained. “A critical feature of the shed design is the floating system for mounting the cool cells that compensates for movement caused by expansion and contraction of the concrete shed base. We use air tight rubber enclosed telescopic footings in the support frames to achieve stability,” Ron explained. Both Daniel Bryant and Ron Sanday w

v agree on the importance of using a locally supplied and fabricated steel shed frame structure. “We believe that by using a locally produced steel frame structure we can ensure consistency of quality and reduce the risk of any hold up in delivery. “That’s very important when we have to finish a shed in less than two weeks in order to comply with our delivery schedule on the Rothdene farm,” Ron stated. “In fact our construction strategies and shed design have allowed us to finish sheds in as little as 10 days,” he added. Frame fabrication and cool pad areas along with the ‘clean skin’ shed interiors are the ‘big features’ of the R & DG Sanday shed but it is smaller detail that adds to the useability and efficiency of the sheds. All personnel access (PA) doors are sliding rather than hinged so the inevitable expansion and contraction of the shed structure doesn’t cause ‘sticky’ operation. “This is an important OH & S issue as a PA door jam would have to be seen as a safety issue,” Ron said. Daniel Bryant, when taking Poultry Digest on a tour of the finished sheds as well as those under construction, pointed to the mounting of the lights set up in a manner that reduces air flow disturbance from the wall mounted mini vents. “It’s a small detail but we rely on optimal performance from the minimum ventilation system, not only to keep the birds happy but also to reduce energy costs,” he said. In operation the sheds are designed for split sex housing and in typical production four to five pick ups are made to satisfy all market categories for broiler meat product. Sheds apart, the investment in supporting infrastructure on the farm is both considerable and comprehensive. Though water is available from the local authorities, a 100 megalitre dam has been constructed as a back up. Water is moved through a filtration and chlorination plant, then into huge supply tanks to be transmitted to the sheds themselves. A lot of effort has gone into landscaping the site and once complete, there will be more than 10,000 trees planted to improve the appearance of the overall farm as well as reducing wind and dust issues. “As well as supporting locally produced manufacturing in as far as is possible for the construction program, we are pleased to be able to offer employment opportunities for a local workforce,” Daniel said. Apart from the shed construction the supply of ancillary equipment is largely attributable to the Bigeni family-run Patarker company. w

NATURA Nova twin Modern realisation of the successful A-frame principle Natura Nova twin has been developed on the basis of the well-proven A-frame principle. The hens are able to act out their natural behaviour and move from higher to lower levels and back, thus distributing evenly throughout the entire system.
Rugged construction, ideal flock control Natura Nova Twin allows for optimum flock control with easy access to all areas. Management of both the birds and equipment is improved. Big Dutchman has in excess of 10 million bird places in aviary systems world wide.
High share of usable area and very good utilisation of the building Higher stocking densities are achieved in the house due to an additional 8.5m² per running meter of bird area available in the system.
Easy reliable production start By its integrated design it’s possible to shut the birds temporarily into the system during their initial housing. This helps to familiarize the birds with the 3 dimensional environment, thus reducing misplaced eggs and allowing the hens lower down the social order to find a comfort zone.

It supplied the Roxell grain silos and cross auger systems and pan feeders; drinkers are Roxell pipe with Lubing nipples/cups. Patarker also suppled the Hired Hand gas heaters, the rack and pinion systems for cool cell housing and the Fancom winch system for the mini vents: the mini vents themselves were supplied by Skov. Patarker was involved also in the installation and commissioning of all internal and external shed equipment, all electrical installations including internal electrical, mains supply, amenities blocks and managers residences. The company was also responsible for the design and installation the backup power systems, the design and installation of the alarm paging system and the training of staff.

The main Euromme fans, shed controllers and cool pads were supplied direct by Munters. Discussing the whole project and future of the broiler meat industry in Australia, Daniel Bryant said “to remain viable in a high volume low margin business we have to work with our integrator (which in the case of Rothdene, is Baiada) to help in containing operational costs. “Though Australia, given reasonable seasons is a highly competitive grain producer, pressures like the current drought in the US mean that feed costs are driven by factors over which we have little control. “By using the best available technology on our farms we have to strive to achieve w

v the best possible performance on a consistent basis,” he said. “Using high levels of automation we can also lower the disadvantages of high Australian labour costs. We will operate Rothdene with four on-site managers and six full time workers. “Always a consideration on broiler farms is biosecurity and we have applied strict protocols to minimise risk both by access to the site and in the design of the sheds which are easy to clean and keep biosecure. “The site itself, being remote from other poultry farms and population centres gives us a great start in our efforts to minimise risk of disease entering the property,” Daniel said. It is interesting to note that all of ProTen’s farms and proposed future developments at this stage concentrate purely on providing broiler meat from efficient intensive and contained shedding. “Obviously the integrators we supply, like Baiada, offer products from alternative production systems but our operations concentrate on intensive production using the best available technology. “It is noticeable that in Europe, where both organic and free range production systems were a significant part of the overall market, the alternative sector collapsed when economic conditions took a downturn. “ Though chicken continues to be popular with consumers, it has to be recognised that in the overall protein market, price sensitivity is a critical factor and we recognise that in our business model,” Daniel concluded.

importance of flock uniformity – how can we improve it in broilers? By torBeN G. MADSeN, evonik industries, Health & Nutrition feed additives, Singapore and JACoB r PeDerSeN, Lantmaennen Danpo A/S Denmark
I
t is well recognised that broiler uniformity is beneficial for optimal performance on farm. With a better homogeneity the nutrient requirements for the individual birds are less variable and less safety margin is needed to meet the requirements of all birds. Therefore, feed cost can be saved and performance improved. However, it is not only on farm level that less variation in bird weight improves efficiency. Today, a large part of broiler meat is purchased by retailers and fast food chains. These customers have rather tight specifications for their purchase and failing to meet these specifications impairs the value of the output from the processing plant. As discussed by Cosgrift (2008), the lower value is related to several stages in the slaughtering and processing of the broilers. It is estimated that the value of carcasses out of spec decreases by more than 40 %. Thus, poor broiler uniformity can be a very costly matter. In this article some of the reasons for broiler variation will be discussed and recommendations will be given to reduce the impact of feed on broiler flock homogeneity. Additionally the actual measurement of homogeneity will be discussed as it is important to be able to detect when homogeneity on farm level is less good in order to actively improve it. Factors affecting broiler uniformity The main reasons for flock variation are related to the breed, sex of the bird and farm management. For years, one of the major breeding goals has been to improve uniformity by selection of pure lines. This practice has led to much higher homogeneity in
20
POULTRY DIGEST, August/September 2012
genetic potential of today’s broilers. Regarding the sex induced variation it can of course be eliminated by sexing the birds but this practice is quite laborious and costly. With modern broiler breeds the difference in growth pattern of female and male birds up to a certain age has been reduced to a level where most broilers farmers operate with ‘as-hatched’ grow out programs in whole-bird production systems. The main reason for poor uniformity today is related to the very broad term ‘management’. One of the major factors within management is of course feeding practice and in the following we will discuss how that can have an impact on flock uniformity. Effect of feed homogeneity on flock uniformity As genetic potential sets the upper limit for performance, the expected variation will decrease when actual performance gets closer to this limit and the further away the actual performance is from the genetic potential the higher the variation can be expected. Thus, all nutrients should be present in sufficient quantities to cover requirements for optimal growth. As variation in nutrient intake can occur due to inconsistent feed composition caused by poor dosing accuracy or incomplete mixing of feed ingredients, it is likely that these two factors affect performance of broilers. However, there are not many studies exploring this effect of feed homogeneity on broiler performance and flock homogeneity, but the few studies that have been conducted clearly show an effect of poor feed homogeneity on performance. Ciftci and Ercan (2003) showed how improved feed homogeneity reduced the variation of slaughter weight in female and male broilers (Figure 1), and Duncan (1989) reported lower performance in broiler starters when feed homogeneity was decreased (Table 1). w

NutritioN feAture It has been argued that poor feed v homogeneity mainly affects early life growth as it was shown by Duncan (1989) where feed intake per chick is relatively low and that broilers to a large extent can compensate impaired finisher phase. However, with the constant reduction in days to slaughter the starter period in modern broilers will account for a higher share of total lifespan. This makes the period for compensatory growth shorter and shorter over time and it has been shown in a number of studies that impaired broiler performance in the starter period due to lower amino acid content will affect overall performance. Thus, impaired performance in the starter period is likely to have a negative effect on final weight, i.e. poor homogeneity at end of the starter period can be expected to persist until slaughter. Dosing and mixing of dry amino acids is favorable for feed homogeneity Flock uniformity is not only determined by the nutrient specifications used for feed formulation but also by how evenly the nutrients are distributed in the feed mix. The question is therefore how we make sure that feed is homogenous and that the amino acids are evenly distributed in the feed mix. The following diagrams (Figure 3) illustrate the results of AMINOBatch tests which determine the coefficient of variation in feed mixtures, comparing the performance of dry versus liquid amino acid additions. Compared under equal production conditions in the field, almost 40% of all CVs applying dry additives were good (CV <
5%) and almost 80% were good or fair (CV < 10%). On the other hand, just 22% of all results for liquid applications were good and almost 50% were poor (CV > 10%). Thus, using liquid products for amino acid supplementation in feed production can be regarded as a risk factor for proper feed homogeneity. Effect of essential nutrient supplementation levels As mentioned it is well documented that deficient levels of essential amino acids will have a negative effect on performance in broilers. This effect will be most pronounced for methionine or sulphur containing amino acids as they are regarded as first limiting. Basically, the response in animal performance to methionine concentration in feed follows the law of diminishing returns, which means that increasing levels of methionine in feed will yield ever smaller increments in performance until reaching a maximum which is determined by the genetic potential of the animal and the prevailing environment and management conditions. Using the respective response curves the optimum dietary amino acid levels for maximising weight gain or breast meat yield or for minimising feed conversion can be derived. However, these calculations are normally based on the dietary effects on average performance of a flock but not considering the effects of dietary amino acid imbalance on uniformity of the broiler flock. A trial was therefore conducted where we looked at the effect of graded levels of dietary methionine on variability (CV) for body weight and breast meat yield as a
22 POULTRY DIGEST, August/September 2012
measure for uniformity (Table 2). As the results show there were strong effects on average performance of live weight and breast meat and interestingly the flock uniformity was also strongly improved by the supplementation of DLMethionine. In addition, the body weight distribution curve was calculated for the four levels of DL-Methionine supplementation. As shown in Figure 2, only a very small fraction of the birds was actually within the target range of 1700 to 1900 g when they received feed without DL-Methionine supplementation. In contrast, the fraction within the target range improved considerably at the highest methionine supplementation level. As mentioned above the improvement in flock uniformity will have a huge impact on the value of the broilers when processed to the final product. Although everybody can agree that uniformity is important it has been difficult to measure and consequently differentiate between farmers that produce broilers with good flock homogeneity and those with less good results. When flock homogeneity is not considered in the payment schemes the experience tells us that it is very difficult to improve. This has and still is a major hurdle to overcome. However, there are now some promising experiences from the Danish broiler industry with photometric imaging of broiler carcasses showing that it is possible to assess carcass size and composition for individual birds at the slaughter house (Pedersen, 2009). The system is based on equations that CONTINUED ON PAGE 26 w

Currently the robustness of the system is being evaluated, but according to the project manager Jacob R. Pedersen the results have so far been promising. A full implementation of this system will allow to pay farmers based on actual flock uniformity, upon which it is believed that all partners involved in the process chain will focus more on improving homogeneity. The additional value that can be captured through that is to the benefit of all partners in the broiler production chain. Conclusion Poor flock uniformity in broilers can have a huge effect on profitability. Improving feed homogeneity and increasing nutrient levels in the feed as well as using easily mixable nutrient sources can improve broiler uniformity. In this context, monitoring carcass uniformity using a photometric system to determine broiler carcass conformation in the slaughtering process has shown promising results.

why check selenomethionine levels in selenium yeast? By PAUL PERUCCHIETTI and WILBERT LITJENS, Selko Feed Additives, The Netherlands
Figure 1
Q
A departments of Trouw Nutrition International and Selko Feed Additives performed a laboratory analysis of selenised yeast product samples sourced in the EU and USA. Results show large differences between product samples on selenomethionine (SeMet) levels, the most effective and active compound in selenised yeast. Selenium is one of the most examined and fascinating trace elements in life. Currently, selenium can be included in animal feed in two forms; as inorganic selenite or as organic selenium yeast.

Both forms have different metabolic routes and effects. Selenium yeast is regarded as a more effective way of supplementing selenium. As more producers of selenised yeast enter the market, benchmarking on quality becomes increasingly relevant. Selenised yeast predominantly consists of selenomethionine (SeMet), which can be converted into selenocysteine (SeCys) by natural turn-over from methionine into cysteine. SeMet is recognised by the animal as normal methionine and absorbed and metabolised following the methionine pathway. When selenised yeast is fed, tissues will be enriched with the selenium from SeMet. If selenium is required, it is rapidly available from SeMet turning into SeCys (Figure 1). This saves valuable time and ensures a fast and effective reaction in case of

Selenium is a nonmetal with properties that are intermediate between those of its periodic table column-adjacent chalogen elements, sulphur and telluridm. It rarely occurs in its elemental state in nature or as pure ore compounds. Selenium (from Greek sefene meaning ‘Moon’) was discovered in 1817 by Jons Jakob Berzelius. Selenium salts are toxic in large amounts, but trace amounts are necessary for cellular function in many organisms, including all animals. Selenium is a component of the antioxidant enzymes glutathione peroxidase and thioredoxin reductase which indirectly reduce certain oxidised molecules in animals and some plants.

stress or a disease. Benchmark To evaluate the nutritional value of different selenised yeast products, a sample benchmark analysis was performed at the University of Pau, CNRS (France). This research lab is known as professional and repeatable for organic selenium species determination. Total selenium, SeMet, SeCys and inorganic selenium values were determined. Eleven samples from each different batch of five different producers were sourced from the market. Samples were randomly numbered and sent to the lab for analyses by HPLC ICP-MS. Results are shown in Table 1. Most interesting are differences in levels of SeMet. As displayed in the table, some samples contain half the level of SeMet of other samples (range from 24.8% to 69.7%). SeCys levels are, as expected, marginally present at all equal levels. Surprisingly, Sample 6 contained a relative large amount of inorganic selenium (13.3%). Need for selenomethionine Yeast can be enriched with selenium through growing it in a medium with a shortage of sulphur and a controlled amount of selenium. This forces the yeast, in order to grow and reproduce, to produce methionine with selenium incorporated. The more methionine is produced as SeMet, the more effective the yeast will be as an organic selenium source for the animal. Looking at all data from literature and published trials, it is generally accepted that SeMet is the most effective and active compound in selenised yeast. The level of SeMet of total Se in yeast is a proper parameter for the effectiveness and bioavailability of the selenium in the yeast.

NutritioN feAture v total selenium level gives a clear estimate of the quality of the selenium enrichment process. Most selenised yeast products contain 97-99% organic selenium of total selenium. The dominant organic selenium is SeMet, which can be accurately (< 5% variation) determined. SeCys is present at fixed, low levels (2-5%) and of minor importance. The remainders are SeMet precursors and SeCys/SeMet intermediate amino acids. These are individually present at very low levels in yeast and most of these compounds are less or not valuable to the animal. Guaranteed high quality Selko Feed Additives markets its own premium quality selenised yeast; Optimin SeY. Besides total selenium, every batch is also checked for selenomethionine content. This must be above 63% selenium of total selenium for the batch to be released for customers. This high guaranteed quality will ensure that animals will get the most out of the selenium yeast (Figure 2). A selenised yeast product with a consistent and higher level of SeMet presents several advantages: first, in feed formulation lower inclusion levels may be needed to meet requirements to save costs without compromising animal performance. Second, when selenised yeast as part of animal feed is used for selenium enrichment of human foods like meat, eggs or
milk, consistent and high selenomethionine content are essential to make health claims on these foods. Conclusion Among all Se yeast products sourced on the market there are large differences in quality and consequently nutritional value of different products. It makes sense to compare producers on SeMet levels and subsequent pricing. Choosing a product which guarantees selenomethionine is the best choice. It gives maximum benefits to animals, enriches animal products and lowers the cost of feed formula.

odour emissions and nutrient accumulation on free range meat chicken farms in Queensland By E. GALLAGHER & G. BROWN, Dept of Agriculture, Fisheries and Forestry
T
he free range chicken meat industry at present accounts for around 15% of total chicken meat production in Australia, but it is a growing industry expanding at approximately 15% per annum (Australian Chicken Meat Federation Inc, 2007). At this time there is little information available regarding the environmental impact of free range meat chicken farming. To support continued growth of the free range sector, improved information and understanding of odour emissions, nutrient accumulation and transport will be required to support local government planning decisions. Recent research (Dunlop et al., 2011) has generated substantial information regarding odour emissions from Australian conventional meat chicken farming, however, this information may not be representative of free range farms if used for planning purposes due to lower stocking density and deposition of manure in the sheds and range areas. There is potential that using data for conventional farms may disadvantage expansion of the free range sector. There is little information in the public domain surrounding the sustainability of free range poultry production. Compared with conventional meat chicken farms, free range farms need to correctly manage the range areas to remain sustainable. Numerous studies have investigated the environmental impact of the land application of litter (Eldridge et al., 2009, Felton et al., 2007, Haynes and Judge, 2008, Smith et al., 2007), however little information is available for range areas. There is one line of thought that nutrient accumulation may limit the life span of the range area and increase the potential for nutrient loss in leaching and
runoff. By characterising runoff from the ranging area, accurate information will be available on the true impacts of free range production. Quantification of nutrient loss/accumulation may help to identify impact mitigation strategies (such as planting vegetation that heavily utilises a particular problem nutrient). This project was split into three sections â&#x20AC;&#x201C; odour assessment, nutrient runoff and soil nutrient accumulation. Odour assessment The aims of the odour section of the project were to determine if range areas contributed to the overall emission of the farm, and to determine if the shed emissions differed greatly from conventional sheds. The project team decided (afterconsultation with industry representatives) to concentrate on farms that used tunnel ventilation. The majority of recent literature is based on tunnel ventilated production, which would allow for more rigorous comparison with conventional production. One farm, however, did operate in natural ventilation mode during a winter batch. Methods Odour samples were collected from two farms in South East Queensland over summer and winter batches. Samples were collected over one day at three specific times during each batch: 1) Before birds were released from the shed; typically day 15-20 2) Day prior to first pickup; typically day 30-35 3) Day prior to final pickup; typically day 42-46 Different areas of the range were targeted on each day: 1) Open sunny area

2) Under shade sail 3) Under trees used by the birds 4) At the shed pop-holes Odour samples were collected using the Australian/New Zealand Standard AS/NZS 4323.4 flux chamber method (Standards Australia, 2009). A flux chamber (stainless steel and plastic dome) was placed over each target area. Odourless cylinder air was pumped into the chamber, from which an air sample was collected over 40 minutes. Samples were then transported to the laboratory and analysed using the Australian/ New Zealand Standard AS/NZS 4323.3 dynamic olfactometry method (Standards Australia, 2001). As olfactometry is a detection method, meaning that the offensiveness of the odour is not taken into consideration during the testing, control odour samples were collected from a similarly grassed area nearby the ranges. Collecting the control samples helped determine whether the grassed ranges were any more odorous than a grassed area with no chickens present. Shed emissions were collected before the first and final pickups. Samples were collected directly from an operating tunnel ventilation fan, or from within the shed during natural ventilation. Odour emissions were calculated on an area basis (odour units per m2) for the range emissions to assess the overall odour emission from the range. Shed emissions were calculated by taking into consideration shed ventilation rate. Results and conclusions Odour emissions from the range area were found to be considerably lower than emissions measured from the sheds. When considering whole-of-range w

MANAGeMeNt feAture v emissions, the day of highest range emissions produced values of 0.85% the average odour emission rate measured from the shed. When compared to the odour emission rate from the control grassed area, the only time when range odour emissions were higher (and statistically significantly different) was during summer, just before final pickup. However, while the range odour emissions were statistically different to the grassed control area, the range was still a minor contributor to overall farm odour emissions. Even though these results indicate that range odour emissions are minimal compared to emissions expected from the sheds, it is worthwhile identifying areas that may cause elevated odour generation. In particular, the areas in close proximity to the shed pop-holes were identified as a location of increased odour production potential. Where birds spend a reasonable amount of time under the shed eaves, manure may accumulate and not dry out during the wetter months of the year.
Discouraging birds from residing under the eaves would reduce manure accumulation in these damp areas, thereby minimising the odour generation potential. On the other hand, compared to the overall size of the range, the areas near the pop-holes represent such a small portion of the whole area that odour generation may not be an issue. It would be worthwhile for producers to keep an eye on the size and condition of these damp areas and take action if required. When shed emissions were compared to Australian conventional tunnel ventilation emission rates (Dunlop et al., 2011), the free range sheds did not display noticeably lower emission rates (odour units per second) for either summer or winter seasons. It is however worth noting that batches during the summer of 2010 and winter of 2011 were used for this work. Rainfall during these seasons was above average, which impacted litter moisture content during summer in particular. In summary, the results indicate that the range as a whole is a minor odour source and only produced odour that was
significantly different than an ordinary patch of lawn during summer, just before the final pickup. Emissions from free range sheds appear to be comparable to emissions measured from conventional tunnel ventilated sheds. Nutrient runoff Nutrient loss from range areas during heavy or prolonged rainfall was monitored at two Queensland farms. Two runoff channelling and measurement devices (flumes) were installed on each farm; a control device to collect runoff from a similarly grassed area with no manure deposition, and a device to collect runoff from the range area of one shed allowing for total nutrient loss to be calculated. Methods In order to channel and measure the runoff â&#x20AC;&#x2DC;Hâ&#x20AC;&#x2122; flumes, as developed by the US Department of Agriculture and described by ISCOÂŽ (2008), were constructed and installed at each site.

small flows, and have been used in the past for measurement of runoff from feedlots (ISCOÂŽ, 2008). Automatic weather stations were set up at both farms to record ambient weather conditions including rainfall over approximately 12 months. Integrated within the weather stations was the ability to report when the sample collection pump at either the control or range sites was triggered by a runoff event. Runoff samples were collected promptly from the farms and stored in food grade high density polyethylene (HDPE) bottles. The samples were then transported either directly for analysis or frozen and transported at a later date. After each rainfall and runoff event, the Bureau of Meteorologyâ&#x20AC;&#x2122;s Rainfall Intensity Frequency Duration program was used to determine how often each event would normally occur. Using this information would help explain how often nutrient loss events could impact on the environment. Samples were analysed for concentration of the following compounds: 5) total nitrogen as N 6) total phosphorus as P 7) ammonia 8) nitrite 9) nitrate 10) nitrite+nitrate 11) orthophosphorus With the data collected from the flow rate through the flume and the reported sampling frequency the total runoff flow for each event could be calculated. This number was then used to determine the total concentration of nutrients (mg/L) present in the runoff event. Results and conclusions As this component of the project is still underway, exact nutrient runoff concentrations are to be determined for the range and control areas at both farms. However, several rainfall and subsequent runoff events have been recorded so far, with some 25 and 10-20 year frequency rainfall events being observed. Soil sampling Also included in this project is a soil nutrient assessment of free range chicken farms in both Queensland and Victoria, with nine free range farms in Queensland and five in Victoria to be assessed. Each farm will have soil samples taken both on and off the range area for analysis of nitrogen and phosphorus content. This sampling aims to provide insight into potential nutrient accumulation on the range area of a free range farm. It should be noted that this aspect of the project has not yet been investigated. This project is ongoing, with completion of field work and final data analysis still to be undertaken.

We would also like to express our appreciation to the poultry producers who continue to allow access to their farms for this research.

NewS training session at Sydney university Camden campus for new elanco Health tracking Scheme staff On August 1, 2012 Tugrul Durali DVM, Technical Service Manager for Red Lea Poultry Sydney, hosted a training session for Elanco and Red Lea technical staff working on the Elanco Tracking Scheme at the University of Sydney Camden Campus where Tugrul is a PhD candidate whose project is comparative digestive physiology and health of free range broiler and conventional broiler. Working in the fast growing Turkish broiler sector after completing his veterinary qualifications, Tugrul acquired plenty of experience in the post mortem examination of birds in commercial flocks. “We organized this training for new Elanco and Red Lea technical staff based on the Elanco Health Tracking Scheme,” he explained. “Elanco has a broad disease database incorporating industry data spanning the past 12 years. “It is based on the post-mortems performed on healthy, normal birds from the national flock and a wide variety of diseases are recorded and tracked in this system, a core component in the latest version being the new intestinal integrity I2 score. “This unique feature is based on a score of 0–100; the higher the score, the better the I2 of the broilers concerned. “It incorporates a number of parameters that are weighted according to the impact each one may have on intestinal integrity. “When a post-mortem is performed on a broiler, all the parameters captured are entered into the system. “The system then calculates the I2 score for the data entered and this is what their system is all about,” Tugrul said. After the post mortem training session was complete Dr Gigoy Tayao Elanco’s Poultry Brand Manager Asia Pacific Rim explained the significance of his company’s Health Tracking Scheme and its history to other members of the Sydney University based Poultry Science Unit including Poultry Research Foundation Director Dr Aaron Cowieson and recent PhD graduate Dr Stuart Wilkinson.

NewS AeCL defines ‘free-range’ Farmers, politicians and animal rights activists have had their feathers ruffled over the Australian egg body’s free-range definition announced recently, with claims it harms ethical producers and puts the industry’s legitimacy in to question. The Australian Egg Corporation (AECL) defined the term free-range as allowing as many as 20,000 chickens per hectare – for the very first time in draft standards sent to producers. The AECL want this definition to be legally enforceable, as compared to the current standard – 1500 chickens per hectare – which is not. The NSW Greens have already put forward a bill to Premier Barry O’Farrell, stating that the definition ‘is making a mockery’ of the term free-range. “They are increasing stocking densities to a level that no consumer purchasing free range eggs for ethical reasons would find reasonable,” said John Kaye, Greens NSW MP. He said it is correct that a legal standard needs to be enforced, but that “the standards they have proposed will destroy genuine free range farmers by allowing large factory farm producers to use the term for eggs that are not by any reasonable definition freerange”. While reports are circulating in the mainstream press, there’s evidence that the AECL has been planning to raise the threshold to 20,000 for quite some time, with the Humane Society International speaking out on the issue as early as June last year. “The changes proposed by the Australian Egg Corporation will allow large producers to charge customers a premium for branding their eggs as ‘free range’ without incurring the additional costs of genuine free range production methods,” a press release from the society read in June 2010. “The proposed AECL stocking density would be a totally unsustainable land use and have serious animal welfare implication.” Various free-range farmers and organic producers agreed with these claims. MP Kaye’s bill is set to be debated in a parliament and says that egg farmers must not have more than 750 hens per hectare to be considered free-range. It also states that there must be shade, shelter and vegetation and no beak trimming.

waitrose raises prices to egg producers in the uK Waitrose has underlined its commitment to British farming by announcing a further increase in the prices it pays to its 119 Columbian Blacktail egg producers. This latest move will help the free range and organic producers cope with increasing volatility in the feed market caused by rising soya and wheat prices. It is also heralds another stage in the development of the producer group model pioneered by the supermarket. Heather Jenkins, Waitrose Director of Agricultural Strategy, said: “We believe that it’s vital to pay producers prices that bolster the sustainability of their businesses as they face rising costs. “We pioneered the producer group model under which we work very closely with our farmers, ensuring the prices we pay take into account costs of production. After a great deal of hard work, this as a further development of that model for our egg producers.”

NewS Aviagen improves ross and maintains its commitment to the Australian industry Aviagen and the Ross 308 have more than 20 years of experience in the supply of breeding stock to the Australian broiler industry. The investment in production and distribution has increased dramatically since 2008 with the acquisition of Bartter Enterprises quarantine farm, grandparent and great grandparent facilities. This was followed by the ongoing investment to upgrade facilities and now the recent commitment to acquire from Inghams the land and buildings on two large farms near Goulburn and Bowral in NSW to increase future domestic grandparent production capacity. At the centre of the business is the Ross 308 breeder and broiler package offering balanced incremental genetic performance each year to the Australian market. The company invests 10% of its gross annual revenue in the continued development of the Ross 308 to ensure that improved production performance and bird health attributes are available for the customer. “Aviagen has the most innovative and unique selection program in the global breeding industry,” said Peter Hanna, General Manager Aviagen Australia. “It has since 2004, utilised multiple selection environments of the first class pedigree facilities together with more challenging conditions to better identify the most efficient and robust families as the source of future commercial stock. “This combination of two selection environments along with another first, the
investment and implementation over seven years ago of a new technology called life time feed conversion monitoring is providing the selection conditions and performance data to ensure the Ross 308 is increasing at a faster rate than competitors, keeping the Ross brand in the lead in the Australian industry,” he said. “Aviagen supplies the rapidly improving Ross 308 through the largest supply network with 14 separate locations and 24 hatcheries around the world. “This commitment to building global production and distribution capacity highlights the company’s long term strategy to serve its customer base with shorter day old chick delivery times, promote chick quality and provide a reliable supply of breeding stock. “The emphasis on a local or regional presence is not only production and distribution. Ross customers and distributors are fully supported by experienced regional
commercial and technical service teams located in the same markets and who understand and experience the conditions faced by customers and distributors. “The team is comprised of experienced poultry people with diverse range of skills and backgrounds to support and grow the business. “These teams can engage specialists for ventilation, hatchery, nutrition, veterinary, production management and processing from within the company or as consultants, to add a further layer of expertise and support. The combined effect of a well resourced, progressive research and development organization continually striving to use innovation and technology to improve performance together with an extensive supply network to optimise delivery times and a committed regional commercial and technical presence is an advantage for customers. “Poultry genetics well supported through R&D and an operating strategy of global presence and local participation has been an integral part of the company and its commitment to remain the supplier of choice for the industry,” Mr Hanna said.

NewS Processing waste adds value Even with the advances in modern poultry production methodology, up to 5% of all broiler flocks perish prior to reaching processing age. This represents a significant amount of material that must be managed. Until now much of this waste material has been buried in landfill or on farm sites, with potential for detrimental leaching into the local environment. This once cheap and unsophisticated method of disposal is becoming increasingly costly and problematic, with EPA and Local Councils increasingly resistant to such practices. With the right treatment however, these waste streams could instead have their value recovered, saving this significant loss of raw materials in the poultry production process. A pilot project being undertaken by Active Research Pty Ltd (AR) and the Poultry CRC proposes an operational trial of the disposal of poultry waste by Anaerobic Digestion (AD). Waste includes poultry carcasses with feathers intact (mortality birds), unseparated eggs and yolks (hatchery waste) and poultry processing sludge.
Layer farm equipment sale Dino Salvatore of Wallan Egg Farm, Wallan, Victoria has decided with regret to call it a day and, as such has a comprehensive list of layer farm equipment for sale. The major item is a Facco 49,950 bird capacity 6 tier Compatta system with intermediate floor – complete with shed. The farm has its own 10 tonne per hour feed mill and all key items of equipment in the mill are for sale including a 2 tonne ribbon mixer, a roller mill, hammer mill, 30 tonne weighbridge complete with bins, silos and augers. There is a 1980 model Staalkat EC 120 Grader- 43,000 eggs per hour- 9 lanes, and a 2000 model KUHL SB 150-12s Egg Washer, 12 row, which Dino describes as being ‘as new’. Though it is sad to see an experienced layer farmer departing, this sale presents a great opportunity for someone else to enter the industry. Call Dino on 0419 565 680 for prices or email dino@ssc.net.au
Utilising AR’s existing mobile pilot digester, the effectiveness of the digestion process will be assessed for hatchery waste, daily mortalities, processing sludge and a mix of these in various proportions. Pre-treatment, digestion and postdigestion processes will be tested and refined in order to best transform these streams of poultry waste. The products of the digestion process
will be high-quality soil nutrient and biogas, which can be used to generate heat and/or electricity. AR’s semi-commercial scale system used in this field trial is sufficiently realistic that it can then be confidently scaled up to a commercial farming and processing size. The outcome of this project will be the development of a best practice template not only for the broiler industry but the poultry industry as a whole, with knock-on benefits to other agricultural and environmental interests.

NewS research alliance puts roseworthy at forefront South Australia’s role in promoting sustainable livestock production systems and best practice in animal health and welfare came to the fore recently at Roseworthy Campus, north of Adelaide. The Southern Star Poultry Alliance was announced on Thursday, September 20, 2012, cementing the education, research, development and extension collaborations between the University of Adelaide and the South Australian Research and Development Institute (SARDI). Professor Iain Reid, Executive Dean of
the University of Adelaide’s Roseworthy Campus, said the establishment of the School of Veterinary and Animal Sciences at Roseworthy has opened many education and research opportunities for South Australia, including this new Alliance. “The Southern Star Poultry Alliance will further enhance the research capability at the Roseworthy Campus, which is already well known for animal science and now veterinary sciences,” Professor Reid said. “The application of our research will have direct benefits to the poultry industry
in the State and the nation as we address a range of key issues, such as poultry health, production, welfare, food safety and nutrition. This will also broaden the student experience at the Roseworthy Campus at undergraduate and postgraduate levels.” Australians consume more poultry than any other meat (44kg per person per annum), and 213 eggs per annum. By 2050 the poultry industry will require 500 million more meat chickens and 15 million more laying hens per year. The challenge facing poultry research scientists and educators is to help the State and national poultry industries achieve sustainable and welfare friendly poultry production as the population increases with a commensurate increase in demand for affordable, high-quality food, the Poultry CRC said. Professor Alan Tilbrook, SARDI’s Research Chief of Livestock and Farming Systems, said SA had been identified by the Primary Industries Standing Committee to take the lead in R&D in the chicken, egg and pig industries. “SARDI and the University, with its expertise, research and education faculties and facilities at the Roseworthy Campus, has an opportunity to lead poultry and other intensive livestock systems R&D in Australia. “SARDI has long been involved in

NewS ensuring poultry, pig and other farming enterprises meet farmer and consumer expectations for sustainable livestock production,â&#x20AC;? Professor Tilbrook said. â&#x20AC;&#x153;Already, we have strong ties with the national Poultry and Pig Cooperative Research Centres (CRCs), with the need for new environmental and production solutions ever present. â&#x20AC;&#x153;We also look forward to increasing our affiliations with industry and the University of Adelaideâ&#x20AC;&#x2122;s School of Animal and Veterinary Sciences.â&#x20AC;&#x153; Chief Executive Officer of the Poultry CRC, Professor Mingan Choct, said South Australia is a â&#x20AC;&#x153;very important State for the Australian poultry industry. â&#x20AC;&#x153;Much of the growth and expansion in the industry is occurring in South Australia,â&#x20AC;? Professor Choct said. â&#x20AC;&#x153;The formation of the Southern Star Poultry Alliance is an important step in the future sustainability of the industry as it helps build capacity in terms of research and extension.â&#x20AC;? South Australia is a net exporter of poultry products to the thriving national market, with thousands of jobs directly and indirectly tied up in production. Production of chicken meat in SA has doubled since 2004, with about 80 million birds or 130,000 tonnes of poultry meat produced every year. SA produces about 7,000 dozen eggs from about 330,000 layers. The Poultry Industry Day at Roseworthy gave local chicken meat and egg producers an insight in to some of the R&D and education activities coming together under the new poultry alliance. The poultry alliance brings together the resources of the new vet school with PIRSA-SARDIâ&#x20AC;&#x2122;s expertise in animal health and welfare, product quality and safety,

NewS CONTINUED FROM PAGE 4 â&#x20AC;&#x153;A 9% improvement in egg shell thickness emerged and the birds fed on the Feedlogic system had half the number of cracks compared with the control flock â&#x20AC;&#x201C; a saving of 22 cents a bird. In summing up the trial Dr Scott stated that â&#x20AC;&#x153;Optimising the layers nurtrient intake to be more closely aligned to the birds net nutrient requirements resulted in overall improved commercial returnsâ&#x20AC;?. â&#x20AC;&#x153;The Feddlogic system can achieve these desirable outcomes in a controlled and automated manner,â&#x20AC;? he said. â&#x20AC;&#x153;The Feedlogic system can allow for feeding (net nutrient) allocations that immediately meet the birds requirements: it can help in dealing with changes to ambient conditions and respond to new seasons grains, disease, market demands. â&#x20AC;&#x153;It will assist in dealing with cost fluctuations in specific raw materials and help to avoid transient (sometimes permanent production and flock behaviour problems) associated with abrupt ration changes,â&#x20AC;? Dr Scott concluded. Dr Peter Selle, University of Sydney, has for a prolonged period been deeply involved with research on Phytate and Phytase and the topic of his paper was a personal perspective of that journey, â&#x20AC;&#x2DC;Past present and futureâ&#x20AC;&#x2122;. He traced the history of Phytase in research and commercial production since its introduction into livestock diets in the v
Netherlands in 1999, and its subsequent overall acceptance in poultry nutrition globally since then. Dr Jonathon Broomhead, Manager Poultry Research and Technical Support, Diamond V Mills USA, presented the data that lead to the title of his paper, â&#x20AC;&#x2DC;Why does 35% (and growing) of the US layer industry use Diamond V XPC?â&#x20AC;&#x2122; Sonia Y Liu, a PhD graduate student from Sydney University, had a novel approach to her subject when she spoke of â&#x20AC;&#x2DC;The Tai Chi of starch and protein digestion dynamics in poultry.â&#x20AC;&#x2122; â&#x20AC;&#x153;Tai Chi, the Yin and Yang in the dynamic changes of protein and starch are of significant factors in poultry nutrition,â&#x20AC;? Ms Liu stated. â&#x20AC;&#x153;Digestion in balance is important for net protein deposition and growth in broilers and starch is digested 50% faster than protein,â&#x20AC;? she added. In identifying future opportunities for further research, Ms Liu stated that â&#x20AC;&#x153;there are extremely few studies on the effects of feed enzymes on starch and protein digestion kinetics which may be more relevant to efficiency of feed conversion than ileal digestibility. â&#x20AC;&#x153;Digestion of protein and absorbtion of amino acids vary and amino acids compete with each other for adsorbtion from the lumen. â&#x20AC;&#x153;Itâ&#x20AC;&#x2122;s necessary to understand the dynamics of the intestinal uptake of amino

In feed application 250 to 425 ppm had delivered consistent results, but if mortality levels rose, 75 to 100 ppm /1000 litres of water had shown instant results in lowering mortality levels,â&#x20AC;? Dr Cadogan explained. The final paper in the monogastric session was delivered by Feedworkâ&#x20AC;&#x2122;s Doug Pearson â&#x20AC;&#x201C; with a little help from friends! â&#x20AC;&#x2DC;FeedLogic, FeedMeter, Nedap & NIR â&#x20AC;&#x201C; On-Line system case studies in pigs and poultry in Australiaâ&#x20AC;&#x2122;, was his topic. The new FeedMeter was of particular interest and in speaking about the â&#x20AC;&#x2DC;payback and value equationâ&#x20AC;&#x2122;, Mr Pearson reviewed the benefits of investing in a FeedMeter. â&#x20AC;&#x153;FeedMeter tracks total feed consumption and can calculate growth rates. You can predict more closely when the birds are ready for their next diet,â&#x20AC;? he said. â&#x20AC;&#x153;The information obviously makes feed scheduling and running feed mills much more effective, saving costs and overall management. â&#x20AC;&#x153;Also, the FeedMeter can alert production managers to bridging or empty feed bins minimising costly production losses with birds being out of feed,â&#x20AC;? he concluded. The 2012 Feedworks Animal Nutrition & Production Systems Conference was a great success with a happy combination of good science, commercially valuable information and the opportunity to relax with friends, colleagues and family. The Coolum venue provides lots of benefits be they golf, the pool and beach as well as good food. The papers were excellent and it is great to see a new generation of scientists like Dr Stuart Wilkinson and Sonia Y Liu join the many long established experts in the conference sessions.

NewS New technology fingerprints 37 different mycotoxins in feed By NIGEL MEADS, Corporate Accounts Manager, Alltech NZ In light of the changing climatic patterns and adverse weather in the world, producers are experiencing more difficulties with mycotoxin contamination in raw materials. In view of this and the changing volumes of grain and commodities traded internationally, mycotoxins are front of mind with many producers in Australasia. There are more than 500 identified mycotoxins, yet until recently, the ability to test for mycotoxins has been limited to relatively few mycotoxins, and the accuracy of some tests is considered by many to be only semi-quantitative at best. Mycotoxins can have negative consequences on the profitability of animal production operations. With recent poor harvest conditions throughout Australia and New Zealand, it is clear that there is a need for a wide ranging assessment technology to assist producers make decisions in the face of threat. Recently in Sydney, representatives
from the poultry industries in both Australia and New Zealand were given an insight into the latest establishment of new technologies that will equip them with accurate assessments of mycotoxins in their feedstuffs. Traditional methodology has used either enzyme linked immune-suppression assays (ELISA) or thin layer chromatography (TLC). Both these technologies have had their limitations, potentially leading to an underestimation of toxicity in feed. A new technology has been developed by Alltech, a company that is well poised to deliver breakthroughs in the area of mycotoxins. Having supported the research thesis of 16 PhD and 19 Masters students, the company has over 60 peer reviewed articles published utilising both in vitro and in vivo models. Following on from a research program at their US bioscience centre,

Alltech developed exclusive methodologies to analyse the presence of mycotoxins through the use of liquid chromatography double mass spectrometry (LC-MS/MS) to fingerprint mycotoxins both in raw materials and in feed. Termed 37+, this new approach confers several advantages over other technologies; â&#x20AC;˘ up to 37 toxins are both identified and quantified in a single test. â&#x20AC;˘ the 37+ program helps detect â&#x20AC;&#x2DC;masked mycotoxinsâ&#x20AC;&#x2122;, mycotoxins joined to sugar molecules that are otherwise missed by traditional methodology. This exposes a more accurate picture of the true toxicity of the feed. â&#x20AC;˘ rapid analysis, needing only a 16 minute run time of the equipment, which means results are relevant. â&#x20AC;˘ Accurate to parts per billion, meaning no second guessing is required on the margins of error. â&#x20AC;˘ 37+ can be done on complete feed. Traditional tests lose accuracy when testing a compound feed, now producers have w

NewS v more flexibility in monitoring. The 37+ program allows for the identification of the so called â&#x20AC;&#x2DC;silageâ&#x20AC;&#x2122; mycotoxin group. This is only the second testing facility in the world with this capacity, the other being a research laboratory in Scandinavia. The silage mycotoxins are unfortunately mis-named. They appear in all feed types, not just silage. In fact, in a recent survey of North American feeds and raw materials, 25 from 72 samples had the silage mycotoxin group present, and of those, 21 samples were not silage. To date, survey work completed in South Asia, North America and Europe has turned up the presence of multiple toxins. In fact, over 60% of samples in North America contained between two and 10 toxins in a single sample. At the time of writing, current survey work has been commissioned and is underway on the 2012 harvest of Australian grains. Work on the 37+ program continues, by constantly researching the future expansion of testing beyond 37 mycotoxins, and with more facilities being established throughout the Asia Pacific region. The 37+ program forms one part of a four
pronged approach that collectively makes the Alltech Mycotoxin Management program. The presentation in Sydney of the 37+ program generated discussion on a topic that is relevant to all animal producers. Different regional surveys conducted by
Alltech show that mycotoxins are an unavoidable risk in animal production. The 37+ program offers an exciting new level of quantification that will help the producers make the best decisions in the face of challenge.
Koozii: new roxell community nest Koozii is Roxellâ&#x20AC;&#x2122;s new automatic nest for broiler breeders and commercial layers. Koozii is especially developed for the production of super quality hatching or table eggs. The community nest was therefore built around the optimised comfort and welfare of the hens. The nest boxes are spacious and oxygen rich while a special positioning of the slats at the entrance avoids accumulation of manure in front of the nest. A wood protection on the entrance board excludes leg and breast injuries. The expulsion of the birds happens extremely gentlly. For broiler breeders this is done through a movable back, while for layers the farmers can choose between a movable

back or a tilting floor. The transportation of the hatching or table eggs to the collection table is done with the greatest care. The AstroTurf pads in the nest prevent hair cracks and soiled eggs. The perforated egg belt not only optimises the climate in the egg channel it also holds the eggs in place so that they donâ&#x20AC;&#x2122;t bump into each other. The eggs reach the collecting table through a smooth and open transition where dirt, feathers and soft shell eggs are removed. Koozii has a wide roof lid for easy control and maintenance. The nest fronts can be opened simultaneously per row by automatic or manual winching for an optimal and fast inspection.
