An experiment was conducted to study the effect of feeding different protein source on carcass characteristics in commercial broilers. A total of 150, one day old cobb chicks were distributed into five treatment groups with three replicates in each group and ten chicks in each replicate. Basal diet (T1) prepared following BIS (2007) standards and the experimental diets were prepared by incorporating blood meal at 5 per cent (T2), fish meal at 5 per cent (T3), silkworm pupae meal at 5 per cent (T4) and meat meal at 5 per cent (T5). The results revealed that blood meal and meat meal at 5 per cent resulted in significant improvement in body weight, feed intake and feed efficiency compared to control and other groups and no significant difference in survivability among all groups.

Highlights

• Conventional protein source like soyabean meal can be replaced with non-conventional feed source like blood meal and meat meal.
• Addition of protein source like blood meal and meat meal is economically feasible for feed production
