Corn kernel chemical and physical traits vary among corn hybrids and could influence growth and production performance in livestock. An experiment was performed to analyze the effects of feeding 6 different corn hybrids on the performance of broiler chickens, laying hens, and pigs. Diets were formulated to be slightly deficient in essential nutrients to increase the likelihood of detecting performance differences, and each hybrid was substituted equally into the diets to obtain 6 dietary treatments. Corn hybrid elicited performance differences, and individual kernel characteristics were significantly correlated with the performance differences. In the case of younger animals, physical traits elicited performance changes more frequently, while in older animals, chemical nutritive content of the kernels elicited performance changes more frequently. While the correlations with performance were significant, they were not sufficiently large enough to cause selection of corn grain for animal diets based on any one chemical or physical trait.
