Nutrient requirement of Kadaknath chicken during the finisher phase to optimize the growth and economic performance

Abstract

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
