Abstract

Young chicks were fed crystalline amino acid diets made first limiting in nonessential nitrogen (i.e., glutamic acid). Addition of 3% L glutamic acid to this diet doubled growth rate. Urea supplementation stimulated growth, even in the presence of a high dietary level of chlortetracycline. Adenine at levels below 0.60% stimulated weight gain and protein retention. Growth was depressed by adenine levels greater than 0.80%, but a high level of chlortetracycline tended to ameliorate this effect. Uracil appeared to be a good source of nitrogen for nonessential amino acid synthesis but neither xanthine nor uric acid elicited a response when added to the nitrogen deficient diet.
