Energy and amino acid digestibility in animal protein sources fed to weanling pigs

Oscar Rojas is a Ph.D. candidate in the Stein Monogastric Nutrition Lab. He discusses the results of two experiments to determine the concentration of digestible and metabolizable energy and the digestibility of amino acids in chicken meal, poultry by-product meal, Ultrapro, AV-E Digest, and conventional soybean meal fed to weanling pigs.
