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.
