Two hundred and sixteen 10 weeks of age hilly chickens were used to determine the effects of dietary energy and protein level on growth performance, carcass characteristics and meat quality. The chicks were randomly allotted in to 3×3 factorial in a completely randomize design. Three levels of energy (2600, 2700 and 2800 ME kcal/kg) and three levels of dietary proteins (16, 17 and 18% CP) were offered ad libitum to the chicks from 10-16 weeks of age. There were no significant interaction effect between dietary protein and energy levels in the diets. At 10-16 weeks of age hilly chickens fed with the medium protein diet (17% CP) showed shortened feed intake (p 0.05). Dietary energy and protein level did not significantly (p>0.05) affect the drip loss, cooking loss and pH of breast meat between the treatments. Based on the data of growth performance, carcass characteristics and meat quality, the optimal dietary ME requirement of hilly chicken from 10-16 weeks of age is 2800 ME kcal/kg and the CP requirement is 16%.
