Probiotic and acidifiers supplementation effect on carcass characteristics of broiler chicken

Abstract

The research was carried out to study probiotic and acidifiers supplementation effect on carcass characteristics of broiler chicken. A total number of 300 birds were reared for a period of forty two days with dietary treatments; T0 - control diet as per BIS (2007), T1 - control + sodium diformate @ 0.2%, T2 - control + sodium diformate @ 0.2 + probiotic @0.02%, T3 - control + blends of acidifiers @0.2%, T4 - control + blends of acidifiers @0.2% + probiotic @0.02%. Each treatment consist of sixty birds with four replicates containing fifteen birds per replicate. The values pertaining to dressing percentage, giblet percentage, boneless breast percentage and boneless leg percentage of all the treatment groups were found to be higher as compared to control with significant increase in dressing percentage, giblet percentage and boneless leg percentage.
