Assessment of supplementation of oregano oil and probiotic on carcass yields of broiler chicken

Abstract

To assess the effect of essential oils and probiotics on carcass yields of broiler, this study was carried out on day-old broiler chicks of Ven-Cobb 400Y strain (n=240) for forty-two days. These broiler chicks were randomly divided into four equal treatment groups with T0 (Control), T1, T2 and T3 with 60 birds in each group having 4 replicates of 15 birds in each group. The treatments were T0 (Control, Standard broiler chicken diet as per BIS, 2007), T1 (Standard broiler chicken diet as per BIS, 2007 + oregano essential oil @ 0.15 gm/kg diet), T2 (Standard broiler chicken diet as per BIS, 2007 + probiotic (encapsulated Saccharomyces cerevisiae) @ 200 gm/ tonnes) and T3 (Standard broiler chicken diet as per BIS, 2007 + oregano essential oil @ 0.15 gm/kg diet + probiotic (encapsulated Saccharomyces cerevisiae) @ 200 gm/ tonnes). Their dressing percentage was significant (P0.05) differences among all treatment groups. So the supplementation of probiotics and essential oils in broiler chicken diet improve the carcass yield by increasing the dressing percentage.
