The present experiment was carried out after completion of an earlier experiment of nutrient requirement of Kadaknath chicken during starter phase (0-6 weeks) was continued for finisher phase (7-14 weeks) to optimize the growth and economic performance. The 270 Kadaknath chickens were distributed into five treatment groups having three replicates containing 18 birds in each. The different dietary treatment groups were viz., control group A: birds fed diet CP- 18%, ME- 2700 kcal/kg, Methionine- 0.38%, Lysine- 0.85%; B: birds fed diet CP- 17%, ME- 2900 kcal/kg, Methionine- 0.45%, Lysine- 0.95%; C: birds fed diet CP- 18%, ME- 3000 kcal/kg, Methionine- 0.45%, Lysine- 0.90%; D: birds fed diet CP 19%, ME- 3100 kcal/kg, Methionine- 0.40%, Lysine- 1.00%; E: birds fed diet CP- 20%, ME- 3200 kcal/kg, Methionine- 0.38%, Lysine- 1.10%. The live body weight and weight gain in treatment groups C, D and E were significantly (P<0.01) higher as compared to control group at the 14th week. The feed intake and feed conversion ratio showed non-significant differences among all treatment groups. The treatment group D was recorded highest live body weights and lowest cost of production rupees per kg live body weights as compared to other treatment groups. The results of the present experiment suggested that Kadaknath birds fed with finisher diet containing a CP-19%, ME- 3100 kcal/kg, Methionine- 0.40%, Lysine- 1.00% from 7th to 14th week of age recorded better growth performance and lowest cost of production of Kadaknath chicken.
