Accomplishments
A. Initiated and completed the following studies:
1. Evaluation of gender and lysine during the nursery period.
2. Supplemental B-vitamins in diets for growing-finishing pigs
3. Validation of the NCR-42 Vitamin-Trace Mineral Mix
4. Influence of dietary P-concentration of P-digestibility
5. 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.
B. Met jointly with the Southern Regional Sow Nutrition Committee (S-1012) in 2004 and 2005 to discuss research topics of common interest. To avoid overlapping research activities, it was decided that applied sow nutrition experiments will be conducted by the S-1012 committee whereas the NRC-42 committee in the future will conduct more basic work in this area.
C. A representative from the feed industry was invited to participate in the 2004 and 2005 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. Invited a representative from NRCS/USDA to participate in the 2005-meeting to present current research priorities in NRCS and to discuss projects that may most effectively be conducted on a regional basis.
E. Wrote two manuscripts based on research conducted at multiple research stations following a common protocol. These two manuscripts were submitted to the Journal of Animal Science and accepted for publication.
Impacts
- Coordinated research studies among participating stations using common protocols.
- Met in 2004 and in 2005 to exchange information and ideas. Met jointly in both years with members of the S-1012 committee and exchanged ideas and information with this committee.
- Submitted research articles based on joint research to the Journal of Animal Science.
- Invited the Chair of the American Feed Industry Association Nutrition Council to participate in the meetings in 2004 and 2005 to discuss research and improve interactive relations between participating research stations and the swine feed industry.
- Invited a representative from NRCS/USDA to participate in the 2005 meeting to discuss research priorities in NRCS and to discuss how participating stations can more effectively cooperate with NRCS in the future.
Publications
Published the following manuscripts that resulted from joint research projects conducted at multiple research stations following a common research protocol.
