Abstract

1. The effects of adding to a basal ration, protein concentrates from animal and vegetable sources were studied by means of growth and body-analysis experiments. 2. There was a small increase in the nitrogen content of the chicks fed the animal protein concentrate, but no differences appeared between lots with respect to their content of calcium and phosphorus. 3. The percentage rate of gain and the gain per gram of nitrogen fed were greater in the lot fed the animal protein concentrate. 4. The lot fed the animal protein concentrate retained more of the nitrogen fed, but less of the calcium and phosphorus fed than did the lot fed vegetable protein concentrate.
