Brief Summary of Minutes of Annual Meeting

Accomplishments Accomplishment since last approval: A. Completed and initiated the following studies: 1. Completed: Supplemental B-vitamins in diets for growing-finishing pigs 2. Completed: Validation of the NCR-42 Vitamin-Trace Mineral Mix 3. Completed: Influence of dietary P-concentration of P-digestibility 4. Completed: Efficacy of inorganic and organic Se fed to grower-finisher pigs in various regions of the U.S. on resulting tissue concentrations and serum GSH-Px activity 5. Initiated: Ca digestibility in in calcium carbonate, monocalcium phosphate, and dicalcium phosphate (Coordinated by Dr. Stein) 6. Initiated: DDGS (Coordinated by Dr. Cromwell) 7. Initiated: Diet Acidification (Coordinated by Dr. Pettigrew) B. Met jointly with the Southern Regional Sow Nutrition Committee (S-1012) in 2006 and 2007 to discuss research topics of common interest. C. A representative from the feed industry was invited to participate in the 2006 and 2007 meetings to highlight research priorities in the feed industry. This resulted in a healthy exchange of information and ideas between the industry representative and the committee members. D. One manuscript on evaluation of gender and lysine during the nursery period based on research conducted at multiple research stations following a common protocol accepted for publication in the Journal of Animal Science. Three manuscripts based on research conducted at multiple research stations following a common protocol being prepared for submission to the Journal of Animal Science. E. Took steps to initiate a revision of the NRC publication on Nutrient Requirements of Swine. Drafted letters seeking support from the National Pork Board, American Feed Industry Association, United Soybean Board, Canadian Feed Industry Association, Canadian Pork Council, and Distillers Grain Council for the effort to revise the NRC Swine Publication Impacts A. Coordinated research studies among participating stations using common protocols. B. Met in 2006 and 2007 to exchange information and ideas. Met jointly in those years with members of the S-1012 committee and exchanged ideas and information with this committee. C. Submitted research article based on joint research to the Journal of Animal Science. D. Invited the Nutrition Committee Chair of the American Feed Industry Association to participate in the meetings in 2006 and 2007 to discuss research and improve interactive relations between participating research stations and the swine feed industry. E. Took steps to initiate a revision of the NRC publication on Nutrient Requirements of Swine. Publications The following manuscripts that resulted from joint research projects conducted at multiple research stations following a common research protocol are being prepared for submission to the Journal of Animal Science: 1.
