Mutant Corns in Young Pig Diets and Amino Acid Supplementation of Opaque-2 Corn¹

South Dakota State University, Brookings 57006

Abstract

Three experiments were conducted with young weaned pigs to evaluate opaque-2, double mutant (opaque-2, floury-2), waxy and normal corn in pig starter diets. Rate of gain and feed/gain were similar for pigs fed the various com types in diets adequate in protein content. Opaque-2 and double mutant corn contained higher lysine levels than waxy and normal corn. Feed/gain of pigs fed waxy corn in 16% protein diets Was significantly less than that of pigs fed normal or opaque-2 corn in 18% protein diets. However, pigs fed 16% protein diets containing double mutant com did not differ in feed/gain from those fed the above 18% protein diets. Successive additions of lysine, methionine, tryptophan, threonine and isoleucine to opaque-2 corn resulted in a significant improvement of feed/gain with lysine supplementation and a further significant improvement with threonine supplementation. Threonine also increased rate of gain significantly. No significant responses in rate of gain or feed/gain occurred with supplementary methionine, tryptophan or isoleucine additions to opaque-2 corn.
