Animal Nutrition Focus of Research Seminar

The Fats and Proteins Research Foundation (FPRF), the research arm of the rendering industry, held its Emerging Issues Seminar in conjunction with the National Renderers Association spring meeting in Cincinnati, OH. The only topic of discussion: animal nutrition.

Dr. Jeff Firman, University of Missouri, emphasized that quality and price are the two most important issues to feed formulators. He said nutritionists need to be trained in computer formulations for proper feed ingredient use, and that increasing the number of ingredients increases the number of possible solutions thus reducing cost. Firman noted that animal fats are generally well thought of among nutritionists in the United States and internationally, with overseas markets increasing their usage of fat. He encouraged renderers to emphasize replacement of fish meal in international markets.

Dr. Eric van Heugten, North Carolina State University, presented the pork industry’s perspective on the use of rendered products in swine diets. Swine producers said cost is the number one driver why a commodity is used in diets, followed by the consistency of the ingredient supply. Many swine producers are using poultry meal in swine diets but worry about contamination, specifically Salmonella, once the meal leaves the plant. Heugten said animal proteins are a good source of phosphorous but have competition from distillers dried grains with solubles (DDGS) and phytase. He urged the industry to ensure rendered products are included in nutrition guides such as the newly released National Swine Nutrition Guide, available at, or the National Research Council’s (NRC’s) Nutrient Requirements of Swine, which is currently going through an update.

Dr. Layi Adeola, Purdue University, focused on using meat and bone meal in swine and poultry diets, reiterating that pricing drives the use of a commodity. He commented that the U.S. Pork Center of Excellence used metabolizable energy information from studies funded by FPRF for the National Swine Nutrition Guide and he believes those same studies will be used by the NRC for its updated swine nutrient requirements. Adeola advised foundation members to revisit the value of meat and bone meal in broiler chicken diets since the current information is outdated.

Dr. Brian Kerr, U.S. Department of Agriculture, Agricultural Research Service, restated meat and bone meal’s competitiveness with DDGS and phytase, and told renderers to examine how good their lab is as results can vary.

Dr. Hans Stein, University of Illinois, wrapped up the nutrition seminar with ways to increase the use of animal proteins and fats in swine diets. He highlighted the data needed for feed formulators, which includes a clear definition of the ingredient, the concentration and digestibility of the nutrients and energy, and the limitations to inclusion rats for performance.

Stein said an excellent way of making this data available is through publications such as the NRC’s swine nutrient requirement guide. To be included in NRC’s updated guide, data must be available by February 1, 2011, with the new guide being published by the end of 2011.

Stein encouraged the foundation and rendering industry to create a “buzz” about using rendered proteins in animal diets by issuing press releases when new research data is available.
