Abstract:
This study evaluated phytogenic growth promoters for broiler chickens. A total of 180 broiler chicks were distributed into four treatment groups 45 chicks: Control group T₁, without any supplementation, T₂ group was supplemented with Black cumin seed @ 300 g/ton of feed. T₃ and T₄ groups were added Black pepper and dry Tulsi leaves @ 300 g/ton of feed, respectively. The trial was conducted with three replicates of 15 in each group. The average body weight was found to be significant in all the six weeks. Weight gain was found to be highly significant in week I, II, III, IV and VI. The average feed consumption was found to be significant in all the weeks. The effect of Black cumin seed, Black pepper and dry Tulsi leaves on feed conversion efficiency were highly significant (P<0.01) at the starter (week I-III) at finisher stage (week IV-VI) and on cumulative feed conversion ratio (I-VI weeks).
