inconnu. A study was carried out to assess the effect of dietary crude protein on growth performance and carcass characteristics of Kadaknath chicken up to 12th weeks of age. A total of 240-day old Kadaknath chicks were purchased from the College of Poultry Production and Management, TANUVAS, Hosur and wing banded, weighed individually and distributed randomly into four experimental groups with three replicates of 20 chicks each. Four experimental diets were formulated with four levels of crude protein viz., 14, 16, 18 and 20 per cent with 2800 kcal/kg ME. Growth performance and carcass characteristics were studied. All the data generated were statistically analysed and interpreted. The Kadaknath chicken fed with 20 per cent crude protein with 2800 kcal /kg ME had highest 12th week body weight (1018.66± 55.19 g ) when compared to other treatment groups. The carcass characteristics of Kadaknath chicken showed significant difference (P ≤ 0.05) among treatment groups for eviscerated carcass weight, eviscerated carcass yield, ready-to-cook weight, ready-to-cook yield and per cent giblets. The per cent cut–up parts of Kadaknath chicken at 12 th week of age did not show significant difference among treatment groups. The present study concluded that Kadaknath chicken fed with higher crude protein (20 % CP) resulted in significantly higher 12th week body weight, eviscerated carcass and ready-to-cook yield.
