Abstract

Three trials were conducted to study the effect of protein-energy relationship as well l as calorie-protein ratio on the performance of broiler chickens from 5th to 10th weeks. lt was observed that diets with 20 to 22% crude protein and 3,000 to 3,200 Kcal/kg metabolizable energy produced significant improvement in both body weight gain and feed conversion efficiency (p<0.05). whereas calorie-protein ratio played only an insignificant role on the two parameters.
