Abstract

This study was conducted at the Institute of Agriculture and Animal Science (IAAS), Rampur, Chitwan for evaluating performance and carcass characteristics of broilers fed with two grades of diets varying in nutrient densities; high amino acid density (HG) diet and medium amino acid density (MG) diet. Two hundred and eighty straight run unsexed Cobb 500 broiler chicks were randomly assigned to two treatment groups with seven pens per treatment such that each pen consisted of 20 chicks. Control birds received MG diet in three phase feeding system viz. pre-starter: 1-15 days, starter: 16-25 days, and grower: 26-38 days. Treatment birds received HG diet in two phase feeding system viz. starter: 1-15 days, and grower: 16-38 days. The birds were provided with diets in crumbled form. At 38 days, with HG diet, feed conversion ratio (FCR) decreased (p<0.05) by 13.72%; body weight, carcass yield, and breast meat increased (p<0.05) by 15.45%, 2.92% and 10.46% respectively. Total feed intake and incidence of mortality among two treatments remained unaffected. At day 38, HG diet produced net profit of NRs. 20.97 per bird. It is suggested that HG diets give better performance with respect to weight gain, FCR, carcass yield and net profit compared to MG diets.
