Abstract The aim of this experiment was to study the effect of optimization of energy and protein requirements in Rajasri grower birds from 9-18 weeks of age on growth and carcass parameters. 360 Rajasri female birds at the age of 9 weeks were randomly allotted to 9 treatments with 8 replicates each replicate consists of 5 birds which are reared in cages upto 18 weeks of age. Nine experimental diets constituted with three levels of energy (2500 kcal, 2600 kcal, 2700 kcal/kg ME) each with three levels of protein (15%, 16%, 17% CP).The results shown that the group of birds supplemented with ME 2700 kcal/kg with 17% CP shown significantly (P<0.05) improved body weights, feed conversion ratio (FCR) dressing percentage, weight of liver, heart and gizzard when compared to the remaining. However, ME 2500 kcal/kg with 15%CP fed group shown lowest body weight and higher feed conversion ratio. The mean feed intake of Rajasri grower birds fed with diet containing 2500 kcal/kg ME and 15%CP recorded significantly (P<0.05) highest feed consumption while lowest feed intake was observed in birds fed with 2700 kcal/kg ME and 17% CP. Based on the overall results, it was concluded that supplementation of 2700 kcal ME /kg diet with 15% CP diet is optimum for growth performance of Rajasri grower birds.
