This study was undertaken to evaluate the carcass parameters of the Broiler chicks when fed with varying levels of the Rosemary leaf powder and Black Cumin seed powder in different treatment groups. The Broiler chicks were divided into ten dietary treatments groups and each dietary group was replicated to three sub-groups for uniform distribution. The T1 i.e. control group was fed on basal diet, while T2, T3 and T4 treatment groups were supplemented with 0.50%, 1.00% and 1.50%, of Rosemary in the basal Broiler starter and finisher ration, respectively. The T5, T6 and T7 groups were supplemented with 0.50%, 1.00% and 1.50% of Black Cumin in the basal Broiler starter and finisher ration. The T8, T9 and T10 treatment groups were supplemented with 0.25%, 0.50% and 0.75% in combination with Rosemary and Black Cumin in the basal Broiler starter and finisher ration, respectively. There highly significant effect was observed on dressing weight per cent, eviscerated weight per cent, while non- significant effect was observed on abdominal fat per cent, liver weight per cent, heart weight per cent, gizzard weight per cent, giblet per cent, blood loss per cent and feather loss per cent due to supplementation of rosemary and black cumin in diet of broilers. It can be inferred that supplementation of Black Cumin 1.00% alone and in combination 0.75 % of both herbs is quite effective and could be viable proposition for lucrative Broiler farming for carcass status.

Highlights

• Significant effect on dressing weight per cent, eviscerated weight per cent.
• Black cumin at 1% alone and in combination with 0.75% of both herbs is quite effective.
