NEwS feedworks Coolum 2010 Nutrition workshop 1

By PETER BEDWELL The Feedworks Coolum 2010 Nutrition Workshop was held at the Hyatt Regency, Coolum on Septemer 8 to 10, 2010. The central theme of the event was ‘Waste Not Want Not – FCR, your productivity: our passion’. Keynote speaker was nutritionist Dr Rob Van Barneveld, who though a pig industry specialist, pointed out facts and events that were just as relevant to the poultry industry. Dr Van Barneveld in his paper, “Why FCR has become even more important,” firstly defined the increasingly complex demands of consumers and retailers. “FCR remains the primary measure of efficiency and driver of profitability in livestock production systems and with every addition ‘product credence value’ the importance of FCR increases,” he said. Dr Van Barneveld defined the concept of sustainable development as being, “the ability to meet the needs of the current generation without compromising future generations. “Population, currently at over six billion will peak at 8 to 10 billion before 2100 and we will need to manage for a peak population rather than a growing one. “Best on current estimates of approximately three billion more people globally by 2050 we will need to increase current food production by 100% and we will have to do this using current arable land and only 1% additional land globally.” We may also have to eat less, particularly in developed countries like Australia, Dr Van Barneveld warned. Food consumption Sydney for instance had risen on a per capita basis from .52 tonnes a year to 1.00 tonne – a 92% increase! “This phenomenon was attributable to food packaging, lifestyle and retailing practice rather than an increase in the appetite of individuals,” he said. “Our target in simple terms to meet global demand would be to double food production and more than double efficiency; focusing on FCR and global energy balance was a way to achieve these goals.” Quoting statistics from his own industry Dr Van Barneveld revealed that, “saving 32g feed/pig/day worldwide (the result of reducing FCR from 2.3 to 2.25) is equivalent to the energy requirements of 2.6 million people for 20 years.

“FCR is more important than ever and will play a major part in assisting producers to stay viable even when satisfying ever more demands from consumers,” he said. “We need twice as much food from the same arable land mass – FCR drives effeciencies to realise that aim.” “Even minor changes in livestock FCR have major impacts on the global energy balance,” he said. At the combined session on September 9, the keynote speaker was Steve Wilson pig and poultry diet specifications manager for the UK’s leasing feed supplier BOCM Pauls Ltd. In his paper ‘Future challenges for the European feed industry’, Mr Wilson reviewed issues of genetics and nutrition, raw materials, the power of the retailer and legislation and feed formulation (does one drive the other?). “Absolute growth rate of broilers is increasing but with the increase in feed intake (30gms/bird) water intake increases (54 gms additional per bird) leading to 5.4 tonnes of water in a 100,000 bird shed and posing obvious questions over litter condition. “There was a need to react to growth rate and adjust diet and management to the birds growth,” he said. “We need to increase diet density but ensure better diet digestibility through raw material selection, enzyme use (Phytase, NSP, Protease) and grist. On issues relating to raw material supply, Mr Wilson pointed to the OECD statistics forecasting a 15% (298 million tons) of extra feed grains being required in the 10 year period from 2005/6 to 2015/16. The change in compounder use of raw materials from 1983 to 2009 recorded a drop of cereals in livestock diets from 44% to 39% with a proportional increase in oilseed and vegetarian by products over the same period. “Ethanol production will account for approximately five million tonnes of a 14 million tonne wheat harvest in the UK,” he revealed. “There are some changes being made under EU legislation to the use of animal by products in livestock feeding but they are, as Mr Wilson demonstrated, complex and highly prescriptive. “Labelling laws are similarly complex,” he demonstrated.

CONTINUED FROM PAGE 4 On the subject of a change in approach to feed additives largely driven by need to find alternatives to AGP’s banned in the EU from 2006, Mr Wilson suggested that a key solution is likely to be related to gut health with management of both environment and diet using organic acids, enzymes, prebiotics, probiotics and betaine. “Food and feed safety were a major concern of food regulators with a focus on microbiological safety and cross contamination,” he said. Finally, in speaking on a topic that would be a significance to Australian growers given recent events concerning Coles recently announced welfare requirements, Mr Wilson spoke of the power of the retailer seeking differentiation in the meat products they offered to ever more demanding consumers. “Key retailer demands concerned welfare, product quality, sustainability, carbon footprint, fear of the media (as in recent UK cloning debates) and issues over GMO feeds,” he concluded. Following the combined session, papers that covered ‘Key Topics that improve FCR’ in the ‘Health’ session followed. Pierre Cronje is an R&D consultant who specialises in applying advances in biochemistry and physiology to develop solutions and products for intensive livestock industries. Apart from being an accomplished scientist, writer and speaker, Pierre Cronje has the happy knack of being able to deliver sometimes complex concepts in an understandable and entertaining manner. His overview address was ‘Foetal programming – the immune system – a double edged sword’. “Selection for high immune responsiveness could impair growth rate in poultry,” he said. Discussing research by Rauw,1998 into immune competence in poultry selected for high or low growth rates, broiler mortality at 42 days from high growth rate birds was 10% whereas it was only 2% for low growth rate birds, he revealed. The final presentation of the day in the session focused on Formulation Feeding to reduce FCR/costs was delivered by Doug Pearson from Feedworks Australia. ‘NIR On-Line – commercial case studies and how does this save money in a feed mill?’ was his topic. “Online application allows NIR to finally realise the truth of the information it has been generating for the last few

decades,” Mr Pearson stated. “The progression from the lab benchtop to at-line measurement when combined, with improved software and diode array technology was delivering far greater benefits through NIR to feed integrators. “To obtain the greatest benefit from any measurement taken, we need to be able to react quickly and efficiently to any detected changes which may effect quality and consistency. Online (Real Time) is the only way to achieve this,” he said. On September 10 in the Monogastric session, Dr Peter Selle from Sydney University in his paper ‘Living with Sorghum (A Moving-Target challenge for monogastric nutritionists and mill managers)’ reviewed recent research into digestibility problems with sorghum. “The variability of amino acid concentrations and amino acid digestibilities in sorghum is extreme,” he stated. “Sorghum has changed,” he said and supported this statement by quoting comparison data from 1995 and 2005 harvests. He then quoted the view of Alan Cruickshank, a plant breeder with the Queensland Department of Employment, Economic Development and Innovation (DEEDI). “Over the last 20 years or so the genetics of commercial hybrids haven’t changed much. “What has changed over that time is the growing environment – both through trends in climate and the movement of sorghum into more marginal environments. “Crops harvested in recent years would be characterised by much more end of season stress than in previous decades,” was Mr Cruickshank’s opinion. Dr Aaron Cowieson, a Scottish academic with a wide interest in poultry nutrition came to the University of Sydney in June 2010 as Associate Professor of Poultry Nutrition and Director of the Poultry Research Foundation at the Veterinary Science Faculty. His paper in the Monogastric session ‘Interactions between feed additives, digestibility, and the re- formulation of diets’, posed the question “Do we really understand what enzymes do and how to use them and, how do we best accommodate enzymes in diet design?” Dr Cowieson addressed the latter question in some detail including the issue of a caution in the removal of fat from poultry diets. “Fat has extra-calorific effects including CONTINUED ON PAGE 46 w

TJ Singh’s old stepped broiler sheds are now being converted to free range sheds.

Historic broiler sheds resurrected for free range production

By PETER BEDWELL

J Singh is a contract broiler farmer with long and well established experience in the Queensland poultry industry. ‘TJ’ as he is known, came out from Britain 25 years ago and acquired his first broiler farm in the Redlands area of Brisbane from Inghams Enterprises. Originally the farm, built in the 1950s, had been a breeder and then broiler

operation. When built, the curtain sided sheds were considered ‘state of the art’ and were believed to be some of the biggest broiler growing sheds anywhere in the world, one shed being 160m by 14.6m, according to Martin Simmons, Managing Director of OEC. Originally the farm consisted of 10 sheds built on two separate sites on the 170 acre property. Two of the sheds, one 100 metres x 14 metres and 60 metres by 14 metres, were built back to back and are ‘stepped’ in order to maintain level floors on slightly sloping terrain – the rear shed being a metre lower than the front one. Two more sheds are 156 metres x 14.6, big by today’s standards, and huge when constructed around 50 years ago. Not long after TJ started running the farm he contracted OEC to supply equipment for a new shed. That was more than 22 years ago and Martin recalls it was one of OEC’s first major contracts. Since that time TJ has acquired three more farms and OEC has grown to be a

major equipment supplier to the commercial poultry industry. Then a few years ago the state government SE Queensland Regional Plan came along and it looked as if Redlands, one of the last large areas of agricultural land close to Brisbane, would become yet another area of residential development as SE Queensland’s population continues to grow at a rapid pace. Many poultry farms in the area, including TJ’s Redlands farm, wound down operations in anticipation of redevelopment. But, as often happens in state and local government plans, conflicting interests collided with environmental and native wildlife concerned groups, putting major pressure on the government, developers and the poor farmers whose enterprises had for half a century helped to feed the growing population of SE Queensland and northern NSW. In the absence of any long term clear way forward, and in many cases after protracted legal battles, a compromise was reached with authorities, whereby existing w

v farming operations, like broiler and layer farms, were allowed to continue to operate. So TJ decided to refurbish his old sheds but transform them into free range broiler sheds for which purpose they are ideally suited. The sheds though old are large, well spaced out, with plenty of space for birds to ‘free range’ within extensive fenced-in areas. So more than 22 years since opening a conventional shed on the Redlands farm, Martin and OEC were back transforming the sheds for a new life and purpose. As Martin points out, the structure of the sheds has remained robust despite their age and if the birds are to be allowed frequent access to outside areas through open ‘pop hatches’, trying to maintain a typical tunnel ventilated environment would not be practical. “So it made sense to improve the existing shed design with modern equipment and electronic aids,” Martin said. When Poultry Digest visited the farm in late September, birds were about to be delivered in a few days and there was still a hell of a lot to do. Torrential rain in SE Queensland as the building crews were trying to restore the clay shed floors, didn’t help the process but progress was being made. The blend of new and old in these sheds is quite remarkable. Looking at the as yet unrenovated sheds, illustrates how labour intensive they were. Skid Steer Bob Cats hadn’t made it past doodle drawings on designers’ sketch pads when these sheds were built, but today anything that clutters a clear floor area means reduced efficiency. TJ therefore had replaced the internal roof support columns with modern steel purlins resulting in clear floor space without compromising building strength. Winches for feeders, drinkers and side curtains that were originally manually operated, are now all powered and modern OEC 1/2 hp 6 bladed, 10,000 CFM circulation fans plus foggers operating at 300 psi combine with new curtains to maintain optimum climate conditions. “New lights, IP 65 compliant, are dimmable and high pressure hose tolerant. LB White Gas heaters are winch mounted and can be lowered into warm areas to reheat warm air thus saving around 30% on energy,” Martin explained. All the critical shed management systems are linked to Rotem Smart 8 controllers, and in the case of the dimmable lighting system, the 2 Channel Rotem RLD 14 Wireless ‘back to base’ alarm/communication systems complete the 21st Century electronic aids to w

v broiler farming. While recycling the sheds, Martin was able to reclaim a number of his fibreglass 40 tonne silos, originally imported from Europe more than 10 years ago, and still sound despite a long working life. Martin points out that there is still potential in old sheds, especially if they are converted to alternative systems like TJ’s free range broiler operation and adding value through improving efficiency and labour saving equipment. “There is the potential, by renovating older sheds, to minimise friction with existing neighbours or future residential development. “As consumers create demand for free range product there is some evidence that residents living near ‘alternative’ farms are more tolerant of these farms than they are of intensive tunnel ventilated broiler sheds. “Though this prejudice is often irrational in basis, there is little doubt that the lack of big powerful exhaust fans in upgraded green curtain sided sheds as well as some strategic planting of vegetation has the potential to reduce neighbour hostility,” Martin suggested. The upgrade of TJ Singh’s Redlands farm is still very much a work in progress but when completed it will be a significant supplier of free range broiler birds to Ingham Enterprises. It is good to see that older farms like this, approached with a mixture of contract grower determination and innovation by suppliers like OEC, can still become valuable entities both to their owners and the ever changing food supply chain. Sadly in an age of ever increasing complexity in the way we are governed and go about our businesses, it is inevitable that their will be the clash of interests like those that have occurred between environmentalists and existing owners of land and commercial farms in the Redlands area. However, rather than be defeated by such challenges, TJ Singh has done the best he could with the cards he held and returned his old farm to production to suit a new era of consumer demand. There is some irony however in the fact that when it was first built around fifty years ago, this farm would have been at the forefront of poultry shed technology that transformed broiler growing from small scale outdoor production to intensive indoor rearing. With this change came the affordable chicken for everyday consumption by Australia’s then booming population. Now many consumers want not only affordable, safe and highly nutritious chicken meat, they want the birds to be reared with access to the outdoors. Farms like TJ Singh’s Redland property demonstrate that, through innovative renovation, the chicken meat industry can once again meet consumer expectation. Also throughout the farm’s long history, first as an Inghams owned production facility, then as a contract grower operation, and now in its third phase as a free range farm, it has throughout that time been linked to Inghams Enterprises. There are many reasons for recycling existing farms like the Singh Redlands operation. Obviously cost saving is a major concern, as is the ability to avoid the hassles and pitfalls that are inevitable in building new sheds in areas subject to environmental and potential residential developer interests. Martin Simmons points out the savings on a day to day operation basis of renovating and converting an old farm over building new sheds. “The Redlands farm overall will be 25% cheaper per bird based on 16 birds per square metre than tunnel sheds with similar

POULTRY DIGEST, October/November 2010

capacity,” Martin said. As for environmental concerns, the koalas living in the Redlands corridor have got along with commercial farming in the region for at least half a century so with a bit of consideration there is no reason why they can’t get along in the future.

NEwS wPSA and DEEDI Top of the Class Awards presented On October 22, 2010 the Queensland Department of Employment, Economic Development and Innovation (DEEDI) and The World Poultry Science Association (WPSA) Queensland Branch, presented awards to the schools and their students who had participated in the Schools’ Poultry Education Competition Awards. The event took place at the DEEDI Redlands Research Station and were part of a poultry industry career presentation seminar at which key members of the Queensland poultry industry mapped out career paths and options in our growing industry. Tanya Nagle, the project coordinator and extension officer (poultry) explained the objectives of the project. “There is a clear need to provide accurate and balanced information to the community on poultry husbandry issues such as antibiotic use, welfare and current research,” she said. “We also aim to strengthen community and consumer confidence in the poultry industries and their products and promote the industry as a sound career opportunity for secondary school students.” Queensland WPSA President Adam Naylor welcomed industry participants and students. One of the key aims of the WPSA was, he said “to advance the knowledge and understanding of commercial poultry production with a focus on education, organisation and research”. The high school project was started 11 years ago in Queensland and Mr Naylor recognised the contribution of Paul Kent who, as a senior research and extension officer at Queensland DPI, put much effort into establishing and maintaining the project. “Thirty-six schools were involved in this year’s competition and it continues to grow,” Mr Naylor said.

nised the importance of the commercial poultry industry to the Queensland economy. “It was,” he said, “a comparative newcomer to the mix of agricultural activities in the state with just three million chickens processed a year in 1950 but over half a billion processed a year today.” Colleen Kleinschmidt, school to liaison officer – Agforce Qld, with her student audience clearly in mind, set about some myth busting. Her first point was that far from there being no jobs in agriculture and poultry in particular there are in fact more than 75000 peopel employed in the sector. And, she stated, “there are serious skill shortages. “There is also a perception that to work in agriculture you can’t live in a big city which just isn’t true,” she said. “Also there are opportunities to work overseas and in developing countries. “You don’t necessarily have to have entered an acemedic career to get a start in the poultry industry. There are all levels of pathways within the industry and often companies will provide the educational structure to further a career,” she said.

An Egg-ceptional combination - Kepnock School trial “Our Kepnock State High School trial is designed to investigate what type of feeds you should give to laying hens to enhance their eggs. This is primarily determined by yolk colour. Our trial involved using 18 laying hens. It enabled us to monitor closely the effect of different supplementary feeds with some accuracy. Our trial consists of six pens (1.8m x 1.27m). Each pen contains three hens in each. The hens are of the same age and each pen contains the same feeder, waterer, nest and a roost and all pens are fed laying pellets along with one of our selected variables. The extra foods we have chosen are: • Pumpkin (Pen 6) • Sweet potato (Pen 2) • Cracked corn (Pen 4) • Cabbage (Pen 1) • Wheat (Pen 3) • And/or grass and weeds (Pen 5)

Groups of year nine students were assigned to each pen to collect and monitor each pen’s progress, along with feeding the hens the assigned food. Each time the eggs were collected, results such as the amount of eggs laid, and when they were retrieved from the pen were recorded. During the trial each group measured and cracked open their eggs to determine the yolk colour for each pen. Each pen’s individual results will be compared with other pens for the overall trial results. As shown by our results and data, the feeding of pumpkin had a significant affect on the yolk colour of eggs – Roche colour fan – 12 to 14. Our other two yellow coloured foods, sweet potato and cracked corn also increased the yolk colour. The use of cabbage did not prove that green leafy vegetables will increase yolk colour. Although the hens being fed wheat had the highest production rate, their yolks were considered to be poor in colour –

Roche colour fan – 3. If we were able to isolate the carotene from the pumpkin we believe it would be a perfect additive for chook feed. Feed produce stores could sell it to egg production companies and it would become a popular feed for chickens. Farms would be able to sell their reject pumpkins instead of leaving them to rot in the fields or throwing them away. By doing this trial we have gained a greater understanding of poultry husbandry, the relationship between diet and egg production and the ability to alter yolk colour through diet.” Assignment written by Sunita Moss, Rachael Cox, Ashley McKinnon, Taylah Driscoll, Micaela Richter and Georgia Dickie, representing Year 9 Agriculture Studies, Kepnock State High School.

NEwS New fowl cholera vaccine registered in Australia Fowl cholera (FC) is an infectious bacterial disease of poultry that is characterised by sudden mortality and respiratory problems. Great variation in the severity of outbreaks of fowl cholera can occur between flocks, locations, and outbreaks in the same location at different times. Fowl cholera is caused by Pasteurella multocida. The incubation period is 1-10 days with rapid spread throughout the flock and farm. The Pasteurella multocida can be introduced by direct contact with infected wild or domestic birds, but rodents are usually the main vector in disease introduction to the farm and flock. Experience demonstrates that Pasteurella multocida is capable of surviving in dead carcasses of birds for weeks. Rodents are a particular risk because they feed on infected carcasses and continue to further carry and spread Pasteurella multocida. Once farm water or feed becomes contaminated, the disease spreads rapidly. Another way to introduce disease to a clean flock is the purchase and introduction of recovered birds from a flock affected with fowl cholera who are still carriers and therefore a source of disease Clinical signs may be: 1) Peracute – sudden death before any other signs of disease. 2) Acute – sudden death. Very short period with clinical signs of discharge from eyes and mouth due to respiratory infection, egg peritonitis and there may be watery green diarrhea present. 3) Chronic – often swollen wattle may be the only sign, lameness due to infections of joints, inflammation and swallowing around eyes and possible twisted neck (torticolis) due to middle ear infection. Egg production and egg recovery is affected. After acute infection some birds remain chronically infected and act as a source of infection for other birds Routine level 1 biosecurity measures should be used to prevent any infectious disease from entering a farm. This includes but is not limited to the provision of dedicated farm clothing/footwear, the use of footbaths prior to shed entrance, exclusion of wild birds from sheds, minimisation of rodents and appropriate rodent control program, drinking water sanitation and people movement from youngest to older

birds areas or from cleanest areas first. (Refer to National Farm Biosecurity Manual for Chicken Growers or similar.) Small farms should also be encouraged to adhere to the principles of isolation, separation of age groups and should also develop appropriate cleaning with disinfection methods and vaccination programs. One to two vaccinations with Pfizer Poulvac i Pabac IV Vaccine will usually stimulate immunity, but the level of immunity may vary due to bird management and conditions. Vaccination is normally carried out at six weeks of age or older and again four weeks later.

“The best way to control and eliminate fowl cholera is with biosecurity, rodent control, hygiene, dead bird elimination from the farm and vaccination.” The best way to control and eliminate fowl cholera is with biosecurity, rodent control, hygiene, dead bird elimination from the farm and vaccination. It is important to keep rodents and wild birds out. Treatment with antibiotics (tetracycline and sulphonamides) of the whole flock is often too expensive. Pasteurellosis is not a hatchery disease. Pfizer Animal Health is recognised throughout the world as one of the leading manufacturers of high quality, effective poultry vaccines. Drawing on its global expertise the company has expanded its vaccine range for the Australian poultry market with the addition of Poulvac iPabac IV fowl cholera vaccine which is a killed vaccine designed for the vaccination of chickens and turkeys as an aid in prevention of disease due to Pasteurella multocida (fowl cholera) type 1 infection in chickens and types 3, 4 and 3x4 in turkeys. Fowl cholera is poultry disease distributed and reported world wide. The disease has been reported in Australian poultry during surveys in broilers, broiler breeders and laying hens (Grimes, 1975; Jackson et al., 1972; Reid et al., 1984) and in all Australian States (Beveridge & Hart, 1985). One of the world’s largest outbreaks

of fowl cholera in chickens with severe mortality was reported here in Australia (Hungerford, 1968). The last reported fowl cholera outbreak occurred in free range chickens in Queensland as reported by Zhang et al., 2004. The disease is caused by Pasteurella multocida. Australian based studies found that the Australian population of avian Pasteurella multocida is very similar to the population seen in other countries and that there is no obvious difference between Australian and overseas poultry isolates of Pasteurella multocida isolates (Blackall et al., 1995 and Zhang et al., 2004). The first publication on the serological characterisation of Australian avian isolates of Pasteurella multocida was the work of Ireland et al. (1989) who reported that majority isolates were either serovar 1, 3 or 3 cross-reacting with 4. A later study by Blackall et al. (1998) reported presence of isolates 1, 3 and 4. This dominance of serovars 1, 3, 4 and serovar 3 cross-reacting with serovar 4 is recognized as being the common in many areas of the world. Poulvac iPabac IV is an inactivated Pasteurella multocida vaccine and contains avian isolates type 1, 3, 4 and 3x4. Poulvac iPabac IV vaccine has been proven to be very effective overseas against different strains of Pasteurella multocida. The vaccine will be very effective aid in protection against strong field challenges of Australian isolates of Pasteurella multocida. The vaccine is for vaccination of chickens and turkeys six weeks of age or older at initial vaccination. Repeat vaccination should be administered four weeks following initial vaccination. Dose for vaccination is 0.5mL by subcutaneous injection under the skin at the bottom of the neck, but not intramuscularly. Duration of immunity in chickens is at least 16 weeks post vaccination and in turkeys at least 6 weeks post vaccination. Birds should be in good health when vaccinated and not under any environmental, physical or social stress. Sick or weak birds will not develop adequate immunity. Local reaction in the form of palpable swellings may be observed at the injection site in all birds for at least four weeks after vaccination. These reactions do not require any particular treatment.

HEALTH fEATURE

Controlling Salmonella via the drinking water By JACO EISSEN and MAARTEN VAN DER HEIJDEN, Trouw Nutrition International, The Netherlands

New legislation by the European Union aims at reducing Salmonella – the major cause of food-borne outbreaks – on poultry farms. The application of organic acids via drinking water offers a strong and flexible contribution to reduce and maintain low levels of these bacteria. The use of organic acids in the drinking water makes dosing flexible and the product is easy to mix with all ingredients in crop, stomach and intestines.

almonellosis is one of the most common causes of foodborne disease worldwide. In humans, Salmonella food poisoning typically causes acute gastroenteritis, which is characterised by abdominal cramping, fever and symptoms such diarrhoea. In more serious cases, Salmonella can escape from the intestine and enter into the bloodstream and travel to other organs, leading to more severe consequences. Most Salmonella infections are zoonotic and are transmitted from healthy carrier animals to humans through contaminated food. The main sources of human Salmonella infections are animal-derived products, especially fresh meat products and eggs. The majority of salmonellosis infections are caused by poultry products (European Food Safety Authority, 2007).

EU legislation New EU legislation focuses on Salmonella control within the poultry production chain, and is aimed at the reduction of Salmonella-positive fl ocks and products. The main driver here is financially penalising poultry meat and egg producers who have high levels of Salmonella on the farm. As of January 1, 2009, egg products are required to be free of Salmonella. Egg producers may not deliver ‘table eggs’ from Salmonella-positive layer flocks, but need to be sold for industrial processing. A Salmonella-positive flock has a significant impact on the producer’s income as industrial eggs have a lower value then table eggs. This further emphasises the importance of Salmonella prevention.

POULTRY DIGEST, October/November 2010

To monitor the Salmonella status of the flocks, laying hen farmers have to analyse their birds (swabs or overshoes) every 15 weeks from 22 weeks of age. Beginning in January 2011, fresh poultry meat products are also required to be free from Salmonella (EC-2160/2003). Products not meeting this criterion may only be sold after treatment as processed food. Furthermore, Salmonella prevalence in broiler and layer flocks must be less than 1% contaminated flocks per country achieved in 2012. This may have a very serious eff ect on the market situation as national prevalence numbers may be used as an import regulating tool with countries having a high Salmonella prevalence being banned to export to countries with a lower prevalence. However, results of the 2007 European Food Safety Authority survey have shown that prevalence levels are above 20% for the EU average, both in broiler and layer flocks. This indicates that serious improvements are necessary in most EU countries in order to produce poultry meat and eggs in line with future legislation. Salmonella control Salmonella is a Gram-negative facultative rod-shaped bacterium in the same pro-teobacterial family as E. coli, the family Enterobacteriaceae. The Salmonella family includes over 2,300 serotypes of bacteria. These singlecelled organisms are too small to be seen without a microscope. Salmonella Enteritidis and Salmonella Typhimurium are the two most common types and account for the majority of all human infections (US Department of Agriculture, 2009). Salmonella bacteria may enter the bird via several routes like water, animal feed, farm personnel, the slaughtering process, litter, tranpsort, pests, housing and farm animals. This has further complications regarding complete control of the bacteria. All these routes, however, do have one w

HEALTH vthing in common – Salmonella enters the bird via the beak where infection may easily develop and spread through the intestinal tract. Once infected, animals may develop into seeder birds that excrete high numbers of Salmonella via the faeces, thereby infecting other birds. In a control program it is important to avoid this cycle of infection and re-infection. It is therefore necessary to pay attention to all the main routes, and to focus on good hygiene, bio-security and management practices.

Organic acids useful Organic acids have shown to successfully help in the fight against controlling Salmonella. After the ban on antibiotics in the EU, organic acids became popular and were used as one of the main replacements, also for the control of Salmonella. Short chain fatty acids are said to be particularly eff ective in killing gram negative bacteria such as Salmonella. Organic acids may be used for controlling Salmonella via the feed as well as via the drinking water. It has become a common practice to blend organic acids for maximum control. Each organic acid has its own physical and chemical characteristics, leading to a specific anti-microbial activity. By combining acids in blends, the product develops a broad spectrum of anti-Salmonella activity leading to more effective control at a lower dosage. Each serotype of the Salmonella family also has its own characteristics, which make it more or less sensitive to the effect organic acids. A blend of organic acids can effectively control the main Salmonella families, with the difference that S. Enteritis is less sensitive compared to S. Thyphimurium. Organic acids may be partially buffered, thereby forming salts in the product. This supports acids in working eff ectively, not only in the drinking water and feed, but also throughout the gastrointestinal tract since part of the acids become available in the latter part of the small intestine. In fact, buffered acid products are combi-products used for controlling Salmonella both in drinking water as well as inside the bird. The use of organic acids in the drinking water has additional advantages. Firstly, the flexibility in dosing means that it is easy to adjust the dosage when needed. Secondly, organic acids via the drinking water easily mix with all ingredients in feed, stomach and intestines. With a regular intake of water throughout the day, organic acids may also support the bird’s system in fighting Salmonella that may enter the bird via other routes. Broiler and layer trials The effect of organic acids via drinking water on Salmonella prevalence was tested in several experiments, with broilers as well as laying hens. All products used were blends of short chain fatty acids buffered with amoonium hydroxide, starting with the drinking water and continuing via the feed into the intestinal tract. Trials were done with laying hens with serious Salmonella problems over the whole farm. Sampling revealed that not only manure samples were Salmonella positive, but also dust samples (cages) and samples taken in ther feeding system. In such a farm, birds were constantly at risk to become infected, or re-infected with the bacteria. A laying hen operation has limited possibilities to reduce the routes of Salmonella as treating with antibiotics is not allowed, and cleaning and disinfecting is not enough to make the flock Salmonella-free. This empasises the importance of Salmonella prevention.

PDOctNov2010:PDFEBMAR09 16/11/10 4:42 PM Page 29

HEALTH In the trial, manure samples were taken right at the beginning before the trial began and at the end of both test periods. Results show that the number of positive Salmonella samples decreased with the use of organic acids during a running laying hen operation, cutting short a main cycle of infection and re-infection. An integrated approach was applied as application of organic acids via the drinking water (Selko-pH) was combined with management measures (HACCP). These broiler farms were followed over cycles, showing a clear decrease in the number of farms that tested positive for Salmonella. Organic acids via the drinking water may also be used for an end-of-pipe solution at Salmonella-positive broiler farms. By applying organic acids in the last period before slaughter, Salmonella presence in the crop may be tackled adequately. This will reduce the spreading of Salmonella in the slaughterhouse and consequently the number of contaminated carcasses (due to crosscontamination). Conclusion These studies demonstrate that organic acids via the drinking water offers a strong contribution to reduce and maintain low levels of Salmonella at broiler and laying hen farms. Due to its flexibility in dosing, application is relevant for prevention of Salmonella as well as reducing Salmonella prevalence in a running (laying hen) operation. * References, tables and figures are available on request.

ACCC cracks down on wA egg wholesalers over free range claims The Australian Competition and Consumer Commission (ACCC) has instituted proceedings in the Perth Federal Court against Western Australian egg wholesaler, C.I. & Co Pty Ltd, and Antonio Pisano and Anna Pisano who have traded under the business name C I & Company (C I & Co), for alleged contraventions of the Trade Practices Act 1974. The ACCC alleges that, by engaging in egg substitution, the wholesaler has breached sections 52, 53(a) and 55 of the Act. The ACCC seeks declarations, injunctions and orders for costs against all parties, corrective notices by Antonio Pisano and Anna Pisano, and an order imposing a civil pecuniary penalty on Antonio Pisano. Egg industry across Australia have suffered from rumours and innuendo concerning the practice of egg substitution, particularly in the free-range sector. This uncertainty has led to consumer scepticism flourishing resulting in a level of community distrust in egg producers and the industry. This investigation demonstrates the consequences for egg businesses who may believe that they can profit from devious practices. AECL anticipates that this action will act as a warning to any egg business considering such deception, and will help to reassure consumers that this is not acceptable practice within the Australian egg industry.

Special tribute to Ivy Inwod It is with great sadness that the Australian Egg Corporation Limited (AECL) has reported the passing of a well known identity of the Australian egg industry. Ivy Inwood of Oakey Queensland passed away suddenly in Brisbane on September 26, 2010 at the age of 68. Ivy was a foundation Board member of AECL, an active participant on AECL committees and a tireless worker for the egg industry. She was characterised by her commitment, passion and dedication to the egg industry which was testament of her character. This led her to being awarded the Lindsay Bell Award in 2008 for services to the egg industry. Ivy’s first priority was the welfare of her birds. In the 1960s she fought the Queensland Egg Board to get the term ‘free-range’, recognised as a specific category of egg. She also fought hard for ‘truth in labelling’. Ivy will be sadly missed by all.

NEwS Australian Poultry welfare Research Seminar The Animal Welfare Science Centre (AWSC) recently presented a seminar at the DPI Victoria facilities at Attwood which looked at aspects of recent Australian Poultry Welfare Research. The AWSC comprises four collaborating partners, the Department of Primary Industries Victoria, The University of Melbourne, Monash University and The Ohio State University and conducts research into:• Welfare methodology to develop and validate appropriate strategies to measure animal welfare • Housing and husbandry effects on animal welfare • Attitudinal effects, notably the effects of the attitudes of animal handlers and owners on the welfare of their animals and also the effects of community attitudes on consumer and community behaviour • Tertiary, post-graduate and industry training. Through these programs, the AWSC aims to inform government and industry in the development of animal welfare policy and appropriate management procedures. Paul Hemsworth, Director of the AWSC, University of Melbourne opened the seminar and defined the aims of the event. Phil Glatz, Senior Research Scientist with the South Australian Research and

Development Institute gave an update on beak trimming research and alternatives to the practice. The infrared method of beak trimming developed in the USA is an innovative procedure and results in lower mortality, however further refinement of the infrared method is required to reduce the incidence of neuromas in the beak stump. Dr Glatz also discussed a range of different products that might be used as repellents in poultry to suppress feather pecking. Joanna Engel, a PhD Student with AWSC, University of Melbourne gave a very informative presentation which considered non-invasive measures of stress in poultry. Blood sampling of laying hens using the most common procedure, venipuncture of the brachial vein, is invasive and can potentially cause a rapid corticosteroid response if the sample is not collected quickly enough. Joanna went on to discuss non-invasive alternatives to measure corticosterone in both the egg and faeces. Greg Cronin, from the University of Sydney gave a very considered round-up of Australian research into nest boxes for laying hens and their effects on hen behaviour and stress physiology. Results from a large experiment suggested that while the nest box was used by the majority of hens as their preferred

Joanna Engel, PhD student from Melbourne University. egg laying site, the choice to not lay in the nest box did not seem deleterious to hen welfare. Indeed, the results suggested that the relationship between pre-laying behaviour and hen welfare is not well understood. For example, increased pre-laying activity seemed to be indicative of reduced stress in laying hens in cages, rather than the intuitive relationship of being indicative of poor welfare. The AWSC is a world leader in the study of human – animal relationships and Lauren Edwards from the AWSC, University of Melbourne looked at opportunities to improve this important relationship in poultry. Lauren detailed research that has shown has shown that reducing fear of humans in laying hens reduces the escape responses these birds exhibit and may lead to welfare improvements during both production and depopulation. Peter Groves, a researcher from the University of Sydney was the final speaker for the day and gave a thorough run-down on the issue of lameness in meat chickens. Peter discussed the complex aetiologies of leg weakness and lameness in the modern broiler chicken, including factors relating to genetics, nutrition, infection, management and environment. He went on to discuss a novel, objective and simple method to assess leg weakness, the Latency To Lie test, which uses the chickens natural aversion to water as a means of assessing it leg comfort or pain. The seminar was attended by a diverse range of delegates, including participants from industry, government, welfare advocacy groups, research providers and the retailing sector.

NEwS Three special themes for VIV Asia 2011 If the current stream of exhibitors confirming their participation or requesting larger stand space is any indication, then VIV Asia 2011 seems set to surpass all previous editions. The Feed to Meat event in Bangkok forms the preferred meeting place for visitors. And not only from Asia – key decision-makers from Europe, Russia, Africa and the Middle East are planning to attend VIV Asia 2011. This is very good news for many exhibitors who were also present at VIV Europe 2010. It appears that VIV Asia is well on the way to making up for the significant numbers of visitors who were unable to travel to Utrecht due to the airport closures in April 2010. With still another five months before the opening, this leading trade show for the Asia-Pacific animal production and processing industries already has a larger surface area (nearly 14,000 m2) than the previous edition in 2009 (12,800 m2) with an even more diversified range of exhibitors. Up until early November almost 500 exhibitors had registered to take part. This is considerably more than two years ago in the same period. The VIV Asia 2011 dates are March 9 to 11, 2011, at the Bangkok International Trade & Exhibition Centre BITEC. VIV Asia has been enhanced with the addition of three special themes; Feedtech-Croptech Asia, LAB@VIV Asia and ChinaVisions. In addition, the new trade show Aquatic Asia will be staged in co-location with VIV Asia. VIV Asia presents the entire Feed to Meat supply chain. The conference program will provide detailed coverage of all the sectors of the trade exhibition concept and the special events. VNU Exhibitions Europe,

the Netherlands, is staging the event in cooperation with NCC Exhibition Organizer NEO, Thailand. The organizers are targeting visitor groups throughout Asia-Pacific, the Middle East and South Africa. Ruwan Berculo, Project Manager AsiaPacific at VNU Exhibitions Europe said VIV is well-known for being the most

international B2B event for the worldwide industries for animal production and processing. “VIV Asia and VIV Europe are part of the Champions League for international events in our industries. With VIV Russia, VIV China and VIV India we have gained clear market positions, resulting in attracting key buyers to these events. At the forthcoming VIV Asia we expect a total of 20,000 visitors from 95 countries. Pre-registration closes on March 11.” For more information: www.viv.net

“Simons is backed by world leading manufacturers of green energy equipment: our core business is in the delivery of sustainable, energy efficient technologies. “The installation of our products will qualify for renewable energy credits and rebates (Federal and State), subject to meeting certain criteria,” he said. “In contrast to fossil energy sources, renewable and low carbon energies rely on inexhaustible sources and they can be used for power, heating and cooling generation. “Specifically, we provide products and solutions for cogeneration, trigeneration, waste heat power generation, then we have solar power generation and hot water options as well as solar desalination and high efficiency hot water boilers. “In looking at the industries that could best make use of our technologies it came to our notice that the growing poultry sector has high energy requirements and produces significant volumes of waste product thus making it an ideal candidate for our energy solutions. “We also realise that farms, particularly in the broiler sector are getting larger, or numbers of independent farms are clumping in areas where local governments favour development of intensive livestock operations. “This creates the economy of scale where large farms or groups of smaller farms could benefit from waste powered cogeneration power plants,” Mr Simons suggested. Henryk Silwa is the Business Manager for Simons Green Energy and has an extensive knowledge of the specific equipment available to his customers and the best combinations to achieve cost effective long term answers to power and waste problems. “Seva Energie AG is a German based company specialising in the manufacture of packaged cogeneration systems and offers a range of electrical power and heating options from 50kWe to 3000kWe,” Mr Silwa explained. “The internal combustion power units of the Seva Energie units can operate on a range of fuel sources including natural gas, biogas, vegetable oil, landfill and mining gas. “The Gas combustion engines have been specifically developed for gas operation and using high grade combustible gases such as methane (CH4) produces a high degree of efficiency through clean combustion and a good CO2 balance,” he said.

COMPANy PROfILE Potters: Easy to manage welfare friendly egg laying systems In recent times we have seen a big move towards eggs from non caged systems. This includes free range and barn production. This has been pioneered in Europe and very specifically in the UK. It has been led by consumer preference for eggs produced from more welfare friendly systems. This is now happening in many countries around the globe and in Australia we see the increased demand for eggs produced from non-caged systems. Potters Poultry is based in the UK and has been manufacturing poultry equipment for more than 40 years. It is a family farming business currently run by the second generation of the family. Along with its manufacturing facilities the company has many rearing farms, producing in excess of one million pullets a year specifically for the free range market. This back ground has helped in the development of all the systems made, which are based on sound knowledge and experience, specifically looking at welfare and ease of use for the bird along with strength, durability and ease of management for the farm worker. With many other countries following Europe this family farming background is used to offer experience and knowledge to the expanding free range and cage free market around the World. Potters now only specialises in non-caged systems for breeders and egg production consisting of aviary/free range rearing equipment. Strong automatic nests and multi tiered aviary systems for

maximising building space and numbers while giving the bird all its natural requirements such as perching, dust bathing, stretching its wings and freedom of movement and allowing the bird to lay its eggs in strong comfy nests. With the market moving rapidly towards cage free egg production there are many areas to look at and potential problems to be avoided. This is where Potters helps its customers and distributors from the rearing of the birds to the housing and management of the pullets in the laying systems. The success of the company has been built on by not only producing high quality equipment but friendly sound advice from its family farming background to producers all over the world. Rearing It is very important when producing pullets for the non-caged systems to ensure they have been specifically reared for this purpose. If caged reared birds are used then many problems will occur, in lack of movement, higher mortality and potentially large numbers of floor eggs. The birds must be trained from an early age to be able to walk around a building and be used to jumping between different levels and finding food and water at different levels. This will produce a strong active bird ready for housing in its laying quarters. The Avirear system produced by Potters allows the birds to explore different levels of the rearing system from an early age and is suited for birds going into aviary systems. For rearing free range birds going into nests and slats it is also important to have staging in the house to encourage the birds to go between levels. Potters also produce a simple rearing system suitable for existing rearing houses, which can also be easily moved between houses and different flocks for the economic use of rearing space. Nests The success of a free range nesting system is not to think cages. Many people in the early days housed birds at high stocking densities and with a cage management mentality. It has been well proven that working on lower stocking densities will give production levels comparable to any cage system. The nests and slats produced by Potters are designed for strength and easy management of the birds. They are constructed of 18mm coated ply in all areas with no hidden parts where red mite can breed and harbour muck and dust. The thickness of the walls offers good insulation in the nest for both hot and cold conditions. The strong rack and pinion lifting floors ensures all birds are expelled from the nests with maximum ease and the nest floor stays clean for the reduction of dirty eggs. It

PDOctNov2010:PDFEBMAR09 16/11/10 4:42 PM Page 39

has also been shown that the lifting floor system will reduce the incidence of broody hens. The eggs roll onto a self adjusting, single 500mm wide egg belt which is strong and easy to manage. There are internal lights in the system designed for the training of the birds to the nests. In designing the houses it has to be easy for the birds to get from one side of the house into the nest with no obstacles. To this end the feeding systems is designed to be either on the slats with a small A frame support or fixed in a perch frame. The drinkers are sited near the nests so the bird goes to eat drink and lay. The slats produced by Potters are to their own design and manufacture and are probably the strongest slat on the market. So being easy for the bird to walk on and keep clean especially if entering the house from outside in wet muddy conditions. They are also very strong and easy for the farm manager to walk on. These slats form an effective pit for the manure and can either be used in 2/3rd of the house giving a scratch area of 1/3 or totally slatted, which is a popular system for Australia where it is not a requirement to provide the scratch area. These are easily removed on clean out. These systems are suitable for new houses, conversations and mobile houses. Nests can be made to many specifications. Either single or double tier and also mounted on the wall. This enables the producer to decide on the best system to suit the house, maximising the layout whether it is in a new building or converting old caged houses or broiler houses. Aviary Another area which has expanded rapidly in recent years is the use of multi tiered aviary systems. These allow for maximising floor space and stocking levels in a house and is suitable for house conversions from cages as well and new purpose built houses. The avitier system manufactured by Potters is designed for all houses. It is a modular system so can be adapted to suit different lengths and widths of buildings old and new. The system is very open and welfare friendly and the birds can move easily between tiers and to the nests. It is built on a single leg to minimise hindrance for the birds and allow for 100 % usage of the floor area. All tiers are clearly visible from the floor by the farm staff allowing easy catching and handling of the birds and for good welfare management. With the open system it is also easy to maintain good bio security on clean out. The nests are built in

a single line allowing the birds to migrate from the multitier system to the nests. The eggs then all go to one single collection point in the front of the house. Aviary systems need good effective lighting systems. This is to minimise the incidence of floor eggs and to help the birds go to the nests to lay the eggs. The Avitier system has lights on all levels. This allows for good illumination of the building and in conjunction with the house lights is used to draw the birds into the house and up on to each level of

perching area. The nest system has built in a low level centre light system this is used to train the birds to the nests and to make the right environment for the bird to lays her egg. With flexible systems it is possible to convert all suitable building for the production of free range or barn eggs. When converting from cages or old broiler houses to building new. The best systems are designed to suit the needs and capital costs of the farm involved and to maximise bird numbers.

Egg shell quality and structure and food safety in the industry

By JULIE ROBERTS, Animal Science, School of Environmental & Rural Science, UNE

new project is just commencing in my laboratory at the University of New England, funded by the Poultry CRC. This project is titled â&#x20AC;&#x2DC;Eggshell quality and risks of food borne pathogensâ&#x20AC;&#x2122; and commenced in mid September. The project aims to identify to what extent defects in shell quality and structure

increase the risk that bacteria on the outside of the egg shell can enter the egg. My co-workers on this project are Dr Kapil Chousalkar of Charles Sturt University, Wagga Wagga and Mr Rowly Horn of Rowly Horn Services. An Industry Steering Committee will oversee the project to ensure that it is as relevant as possible to the Australian egg industry. The project will also liaise with Drs Margaret Sexton and Andreas Kiermier of SARDI in Adelaide. A Master of Rural Science student, Samialluh from Pakistan, based at the University of New England, will also be working on aspects of this project. Essentially, the Australian Egg Industry produces a very safe product. Australia is fortunate in not having a problem with Salmonella Enteriditis in its layer flocks as is the case in North America and Europe. However, Salmonella Typhimurium causes problems with food-borne illness from time to time and some of these occurrences have been traced to the consumption of eggs. For this reason, the Australian Egg Industry needs to be vigilant in monitoring the impact of food

Select Doser

The structure of the eggshell borne pathogens such as Salmonella in eggs and egg products. The table egg possesses many properties that contribute to its safeness as a food source. The role of the egg in nature is as an incubation chamber for a developing chick. Because of this, the egg possesses an impressive arsenal of anti-microbial features which also serve to make the egg contents safe for consumers. The outermost layer of the egg shell, the cuticle, presents an important barrier. The cuticle covers the surface of the egg and partially blocks the pores in the egg. Next there is the egg shell itself which provides a mechanical barrier as well as having an organic matrix which contains anti-microbial factors. The outer and inner shell membranes also have anti-microbial properties as does the egg albumen (see drawing of transverse section through eggshell). The way in which the foundation of the egg shell is laid down, particularly its attachment to the shell membranes is very important in determining the strength of the egg shell and how effectively it prevents bacteria from entering the egg. The fine structure or ultrastructure of the egg shell may be examined by carefully removing the inner shell membrane from pieces of shell that have been soaked in water and then drying the shell pieces before removing the outer shell membrane using a special machine called a plasma asher (or etcher) which oxidizes away the membrane at a relatively low temperature using ionized oxygen gas.

PDOctNov2010:PDFEBMAR09 16/11/10 4:42 PM Page 43

PRATU SPEAK The pieces of shell are then coated with a very thin layer of gold before being viewed under a scanning electron microscope. The University of New England has just purchased a Neoscope benchtop scanning electron microscope which is easier to use than the large machines. The project will investigate the incidence and significance of minor defects in the ultrastructure of the egg shell such as ‘translucency’ which is where lighter colour spots are observed when an egg is candled over a light source (see photograph of translucent egg being candled). These spots appear when moisture from the egg albumen seeps into spaces within the fine structure of the egg shell. They are difficult to detect in very fresh eggs. There is some evidence that translucent regions of the egg shell 5:10 are more easily IghamAdYrbk 1/17/08 PM penetrated by bacteria than areas which are not translucent. Another feature of egg shells that will be investigated is ‘micro cracks’ which are very small, fine cracks that are not visible to the naked eye and which can be difficult to detect by candling, particularly in very fresh eggs.

Micro cracks have the potential to facilitate the entry of bacteria into the egg. The research project aims to address this industry issue by achieving the following: • Elucidating the correlation between egg shell translucency, shell strength and product safety in laying hens. • Determining the relationship between egg shell translucency and the occurrence of microcracks in the eggs of commercial laying hens. • Determining the effect of egg shell translucency, the presence of microcracks, the quality of the shell cuticle and egg shell thickness on the ability of bacteria such as Salmonella and E. coli to penetrate the egg shell • Determining the correlation between strain of hen, stage of lay and bacterial load Page 1 on the eggshell surface and in the egg contents • Sampling flocks for the presence of foodborne pathogens, where problems are identified in eggs from these flocks • Determining the role of egg washing in bacterial penetration of eggs.

PRODUCT NEwS feedworks to distribute Novartis products Feedworks has recently concluded an agreement with Novartis Animal Health Australasia to distribute its range of fly control products inAustralia to the poultry and animal production sectors. This includes the well known brands of Larvadex, Neporex and Agita. Larvadex is a registered in-feed product for poultry that is a very effective management tool for producers. Flies are not just a nuisance; they carry diseases which pose a serious health hazard to people and animals. Globally, they cause livestock and poultry production losses estimated in the billions of dollars. Non-biting flies feed on secretions from the eyes, nose and any small wounds. This distracts animals from grazing, causing a reduction in growth and productivity. Non-biting flies are not key vectors of any specific disease organisms, but because of their feeding and reproduction habits, and the structure of their feet and mouthparts, they can act as mechanical vectors for a whole range of pathogens, from viruses to helminthes. They are known to be involved in the transmission of more than 65 diseases to humans alone, including typhoid fever, dysentery, cholera, poliomyelitis, yaws, anthrax, tularemia, leprosy and tuberculosis

Biting flies can cause even greater irritation to domestic animals, and they too are vectors for disease transmission. However, because they feed on blood, they can also cause anemia and hypersensitivity. The growth and performance of nearly all farmed animals are adversely affected by flies, especially when they are present in high numbers. Infested animals become harassed and feed intake is drastically reduced. The result: significant reductions of meat, milk and egg production and serious economic losses. Whenever fly populations reach plague proportions in locations close to human habitation, they represent a serious health and environmental hazard, not just to the farmer, but to neighbors and local communities. This has long been one of the major challenges to intensive live stock production in areas adjacent to urban areas. The major diseases transmitted by flies to humans and domestic animals are enteric diseases and eye infections. Happily, help is at hand via this new range of fly control products with application either In-feed or within the housing environment. Further information about the major diseases carried by flies is available by contacting Feedworks on 03 5429 6458.

Update on Aviagen In more than 120 countries, Aviagen works to meet the ever-expanding needs of the commercial broiler industry by developing pedigree lines for the production of commercial broilers under the Arbor Acres, Ross, and Lohmann Indian River (LIR) brands, according to the company. “With industry experience dating back to 1935, Aviagen selects the best genetics for the broiler industry. This results in breeding stock products that deliver the highest economic performance, ensure optimum health and well-being, and address the complete range of market needs. “Two strategic parts of that global supply network are Aviagen Australia and Aviagen New Zealand (AANZ), whose production facilities have been operating for more than two and a half years. Aviagen NZ was established in December 2007, and Aviagen Australia in April 2008. AANZ sells Ross broiler breeders in Australia and NZ, with sales of all company brands in Asia and Papua New Guinea. “These two organizations are crucial parts of an infrastructure that ensures the global customer base can receive a consistent supply of top quality breeding stock. As Asia is one of the key growth regions of the world, we are committed to continually investing in both facilities to better serve the expanding customer base there, and to meet increasing domestic and export demand,” the compnay says. “By continuing to invest in these facilities, Aviagen is ensuring that the birds are of the highest possible standard. In addition, production operation and employees follow strict biosecurity protocols to protect breeder flocks from potential disease risks. “Aviagen has also established a local customer support team to better service customers in the region. “Demand remains strong for Aviagen products domestically and throughout the Asia region, signaling the need for further investment in facilities and people. “Customer requirements are changing in the region, as well, and these shifts may someday lead us to offer other poultry lines or strains from the Aviagen portfolio . “As this region shows itself to be one of the most dynamic in the world, the investments Aviagen has made in Aviagen AANZ are paying dividends, enabling this vital arm of Aviagen’s global supply network to serve customers with the highest performing products in the poultry industry.”

PRODUCT NEWS Mini Data Projectors add new dimension to presentations Barry Shuttleworth who runs Hots Communications has developed a speciality of transforming business presentation and communication with the best and most convenient technology on offer. Recently his company has developed a range of mini data projectors and ancillaries that ideally suit one to one, or small group presentations. “Though computer equipment has miniaturised and evolved, data projectors have remained large, heavy and in comparison to most communication equipment, expensive,” he said. “At Hots we offer a range of mini projectors and supporting equipment like folding screens and speakers that match the portability of small laptops, iPads and even smart phones that can be used in conjunction with our projectors. “These mini data projectors are ideal for presentations to small groups and require little space to set up. They link to a laptop or DVD player and we stock stand

alone models with up to 4GB of on-board memory. “Miniature doesn’t mean poor quality either – depending on specific needs our range of projectors go from 15 lumens to 100 lumens light output. “Screen image size can range from 5 inch to 80 inch depending upon individual projector type. “Our vibration speakers when placed on a conventional table surface or cupboard deliver tremendous sound quality.” For most however, it will be the size, weight and easy portability that is the key attraction, apart from affordability. “The baby of the range (Visimax) weighs 120 grams, is 90 x 58 x 27 mm in size, has a 30-40 minutes battery life (internal rechargeable); projects an image size of 12 to 60 inches, and costs just $360 plus GST and delivery cost. “Even the top of the range 100 lumens output model is only 136 x 120 x 54mm, weighs 640 gms, has remote control

capability and costs $800 plus GST and delivery costs. Having started to market its mini projectors, HOTS is constantly sourcing new equipment to complement the expanding projector range. The website www.miniprojector.com.au has all relevant information or email sales@hots.com.au

NEwS v CONTINUED FROM PAGE 8 slowing gastric emptying and improving mineral, CHO and protein digestion. “Removal should be done with care, especially in the neonate,” he said. “There is money in improving fat digestion – emulsifiers, fat digestion and research with Bredol to improve FCR over the last 12 months’, was the title of Dr David Cadogan’s (Feedworks) paper. “By utilising emulsifiers like Bredol in feed an increase of 10 to 25% of milling output is possible as well as reduced power costs. “Expect to retain 1 to 2% extra feed moisture, improve bird performance, as well as product quality and to restrict moulds,” Dr Cadogan said. On the question of using Bredol 683 or Bredol 688 Dr Cadogan pointed out that ‘683’ was the great all rounder for feed (and water/liquid), processing/milling and for nutritional benefit. “Bredol 688 produces a greater protein solubility/dispersion, and probably is the better on intestinal fat digestion. “Bredol 688 is a powder and 683 a liquid. The cost of ‘688’ is approximately 25% higher,” he concluded. Dr Marnie Mellencamp, Director of Immunology at Ralco Animal Health, in her paper, ‘Regano when used as an antimicrobial/coccidiostat and what we’ve seen’, said “Containing oregano essential oil, Regano promotes anti-microbial, anti-fungal, and anti oxidant activity in numerous livestock species including broilers.

“Poultry industries in many markets are investigating feed additives that improve gut health and help to reduce antibiotic use, as regulatory pressure for the removal of anti biotics from commercial livestock production increases. “Regano is a pharmaceutical grade product steam distilled to assure purity using cultivated oregano plants. “It is standardised for active ingredients and contains no synthetic phenols,” Dr Mellencamp stated. “The product contains 34 components of which Thymol and Carvacrol are significant for anti microbial activity. “They are effective against bacteria such as E.coli, Salmonella and other gram negative enteritic bacteria. “The detrimental effects of fungi such as Aspergillus, fusarium, Penicillium, Cladisporium and Candida can also be reduced by Carvacrol and Thymol,” she said. “Unlike antibiotics the development of resistance is unlikely,” she added. In describing trials conducted on broiler farms internationally, Dr Mellencamp stated that Regano had been effective in Coccidosis and Enteritis control and delivered improved performance. In concluding her paper Dr Mellencamp suggested that apart from just substituting the function of antibiotics, Regano could be used to ‘spell’ antibiotic treatment to reduce likelihood of resistance developing.

generation farmer based near Tenterfield in NSW, has long experience in domesic poultry rearing and issues of sustainability. His consultancy ‘PoultryWorks’ specialises in free range and organic production methods. His paper ‘Alternative health strategies for organic and free-range poultry’ drew attention to pressure from supermarkets to provide meat products from ‘ethical sources’ and the pressures that this development will place on growers, livestock and the environment. Such is the interest in alternative production systems that Poultry Digest plans to run this paper at length in a future issue of the publication. Finally in the Monogastric session, Dr Gary Partridge, Global Technical Services Director, Danisco Animal Nutrition gave his paper ‘Recent experiences with existing and brand new Danisco products’. He revealed trials that demonstrated Phyzme XP shows higher bioefficacy than Naturphos in broiler diets. Next was Danisco’s Phytate raw material survey featuring data on wheat and sorghum based diets then reports on research into xylanase responses in more fibrous diets. He explained benefits of protease in addition to xylanase and amylase in broiler diets. He also introduced new probiotic product lines and spoke about trials using the ‘Direct Fed Microbial’ (DFM) product for healthy nutrition solutions in broilers and turkeys. “Enviva Pro product lines have been successfully introduced into the US poultry industry with current market share of 35% of total turkey sector and significant sales in natural broiler and layer sector production,” he said. In concluding Dr Partridge talked about the new Danisco Genencor Division – a joint venture with DuPont to develop second generation cellulosic ethanol from non feed plant material. A lot of information was delivered during The Coolum 2010 Nutrition Workshop, and apart from good science there was a great social program for delegates and their families. For those who missed the conference or would like more information on the papers delivered, Feedworks will provide a ‘thumb drive’ (or CD) with more detail, including trial material.
