Abstract:
Four hundred eighty day old mediocre broiler chicks were reared in D₁ (500 cm²/bird), D₂ (700 cm²/bird) and D₃ (900 cm²/bird) densities. Two protein levels i.e. P₁ (21% cp), P₂ (23% cp) with isocaloric energy (2800 - 3000 Kcal ME/kg) was utilized to prepare rations. Each ration was supplemented with amla fruit powder (AFP) at A₁ level (1 kg 100 kg ration) and A₀ level (without AFP). Experiment was conducted in factorial design. Broiler in D₃ P₂ A₁ treatment attained higher body weight with significantly superior feed efficiency than all other treatments. Irrespective of protein and AFP, D₁ density broilers has poor performance respect to all traits measured. Similarly main effect showed that D₁ density broilers has inferior body wt. FE, carcass yield and high percentage of moisture and nitrogen in litter with increase incidences of foot pad lesions. P₂ protein has significantly higher body wt. and FE whereas A₁ AFP revealed significantly improved FE. Effect of protein and AFP on % litter moisture, nitrogen, foot pad lesions and carcass yield was non significant.
