Abstract
SUMMARY: 1. Nitrogen balance studies were made on 8 Friesian steers given allconcentrate diets containing fish meal, soya bean meal, groundnut meal or cottonseed meal.2. There were no differences in nitrogen retention but voluntary feed intake was significantly lower on the fish meal diet.3. Adjustment of nitrogen retention to constant dry matter intake resulted in significantly higher values for the diets containing fish meal and cottonseed meal than for the others.4. Rumen pH, rumen ammonia and blood urea were all much lower on the fish meal diet.This publication has 8 references indexed in Scilit:
