Nonruminant Nutrition: Amino Acids.

This article presents abstracts of various papers related to nonruminant nutrition, that were presented during the symposium held on July 26, 2005, Cincinnati, Ohio, which was organized by the American Dairy Science Association, the American Society of Animal Science and the Canadian Society of Animal Science. One of the papers presented is "Evaluation of Gender and Lysine During the Nursery Period," by G.M. Hill, S.K. Baidoo and others. Split-gender feeding in the grow-finish period was an innovative technology of the last decade. However, due to various weaning strategies, it has not been adequately evaluated in the nursery. The results demonstrate that increasing lysine concentrations in nursery diets results in improved pig performance of both genders, and there appears to be no benefit in split-gender feeding during the nursery phase. Another paper discussed is "Effect of Replacing Fish Meal With Synthetic Amino Acids in Diets for 8 to 15 kg Pigs," by B.W. Ratliff, A.M. Gaines and others. At a commercial research site with pigs of high health status, three independent experiments were conducted to evaluate the effect of replacing fish meal with synthetic amino acids in diets for 8 to 15 kg pigs.
