Extract

1. Nitrogen balance studies were conducted on 8 early-weaned calves fed on four diets containing respectively Peruvian fish meal, soya bean meal, groundnut meal and dried distillers grains as the major sources of protein.

2. Nitrogen retention differed significantly between diets, being highest on the fish meal diet, and lowest on the groundnut diet.
