Accomplishments

A. Completed and initiated the following studies: 1. Completed: Mycotoxin (Vomitoxin) problem with swine (Coordinated by Dr. Mahan) 2. Completed: Effect of dietary P concentration on Ca digestibility (Coordinated by Dr. Stein) 3. Completed: DDGS withdrawal and belly firmness and iodine value of carcasses of growing-finishing pigs (Coordinated by Dr. Cromwell) 4. Terminated: Impact of piglet birth weights on subsequent growth performance (Coordinated by Dr. Shannon) 5. Initiated: Dietary fat sources and levels for weanling pigs (Coordinated by Dr. Mahan) 6. Initiated: Evaluation of digestibility methods (Coordinated by Drs. Kerr and Crenshaw) 7. Initiated: Effect of phasing of distillers dried grains with soluble on growout performance and carcass quality (Coordinated by Dr. Cromwell) B. Met jointly with the Southern Regional Sow Nutrition Committee (S-1044) starting in to discuss research topics of common interest. C. A representative from the American Feed Industry Association (AFIA) has been invited every year since 2006 to propose and discuss research priorities in the feed industry. This led to exchange of ideas between the industry representative and the committee members. D. One manuscript on calcium digestibility based on research conducted at multiple research stations following a common protocol has been accepted for publication after minor revisions. Another manuscript on the use of corn distillers dried grains with solubles based on research conducted at multiple research stations following a common protocol has been accepted for publication after minor revisions. E. A committee has been established to revise the NRC-Swine Nutrient Requirement. Seven members of the 10-member committee are members of the NCCC-42 and S-1044 committees. Various organizations (USDA-NRC, National Pork Board, American Feed Industry Association, Institute for Feed Education and Research, United Soybean Board, Canadian Feed Industry Association, Canadian Pork Council, IL Corn Board, MN Corn Board, NE Corn Board) have provided financial support for the revision. The committee is well advanced in their deliberations on the new requirements, and the final document is expected to be released in 2012.

Impacts

Coordinated research studies among participating stations using common protocols.
Provided essential opportunity for communication and co-ordination among swine nutritionists at Land Grant Universities, leading not only to joint NCCC-042 projects, but other collaborations as well.
Met annually since 2006 to exchange information and ideas. Met jointly with S-1044 committee during this same period.
Published research articles based on joint research in the Journal of Animal Science and submitted information the key extension and industry publications such as the National Hog Farmer to ensure dissemination of research results to a broad audience.
Invited the National Program Leader Animal Production Systems USDA National Institute of Food and Agriculture (USDA-NIFA) in 2010 to provide an update and discuss the current research, education and extension priorities.
Invited Dr. Victoria Siegel, Office of the Indiana State Chemist, Purdue University, to discuss the AAFCO Collaborative Sample Check Program and methods of enhancing the quality of laboratory assays.
Majority of the 10-member NAS-NRC Swine Nutrient Committee are members of NCCC-042 committee.
Members are active in American Society of Animal Science Editorial Board (Division, Section Editors and Board Members) and in regional and national meetings as speakers and coordinators.
