Nitrogen Balance of Dogs Fed Lime‐Treated Corn Supplemented with Proteins and Amino Acids a, b

SUMMARY The effect on the nitrogen balance of young dogs of supplementing lime‐treated corn with small amounts of black bean flour, skim milk, fish flour, and torula yeast was investigated. Although the diets were kept isonitrogenous, all supplements increased nitrogen retention significantly, as did supplementing with lysine and tryptophan. The gain was most marked for skim milk, fish flour, and torula yeast plus lysine, and of sufficient magnitude to be of practical significance for human feeding. The better the protein quality of the supplement, the greater the decrease in nitrogen retention after its removal.
