High Lysine Corn Fed Free-Choice to Growing-Finishing Swine

Analyses of opaque-2 corn have indicated a higher content of lysine and tryptophane than found in normal corn. Since these two amino acids are the most limiting amino acids in most practical swine diets, opaque-2 corn should permit a reduction in the need for supplementary protein. Experiments conducted at the South Dakota Agricultural Experiment Station and at other Experiment Stations have shown this to be true, with less protein supplement needed in swine rations containing opaque-2 corn than in rations containing normal corn
