Protein needs and amino acid requirements are of major interest in the swine industry today. A considerable amount of research has been conducted on these subjects and more is sure to follow. Amino acid content and balance are now being recognized as more important factors in swine nutrition than total protein alone. Recently, the development of opaque-2 corn with higher amounts of lysine and tryptophan than normal corn has stimulated interest in its presence in simplified diets to supply the amino acid needs of swine. Performance of pigs fed opaque-2 corn has generally been superior to that of pigs fed normal corn. Although opaque-2 corn is inadequate as the only source of amino acids in a growing pig diet, it may, with proper supplementation, prove to be a practical and economical base for swine diets. Data suggest that pigs require less supplemental protein when fed opaque-2 corn than when fed normal corn. The purpose of the research presented herein was to study the adequacy of the essential amino acids lysine, methionine, tryptophan, threonine, and isoleucine in opaque-2 corn diets for young pigs. Rate of gain, feed efficiency, and plasma amino acid levels were criteria used to evaluate the diets.
