abstract
An experiment was conducted with one hundred eighty numbers of day-old broiler chicks (Vencobb-400) to assess the effect of dietary antioxidants supplementation on broiler performance. The chicks were divided into T₀, T₁, T₂, T₃ and T₄ having 3 replicates of 12 chicks in each group. Chicks in group T₀ were given basal diet without antioxidant supplementation and T₁, T₂, T₃ and T₄ were supplied with antioxidants into drinking water as vitamin E@100mg/l and Selenium@ 0.2 mg/l, vitamin E@200 mg/l and Selenium@ 0.3 mg/l, vitamin E@100 mg/l and vitamin C@100mg/l and vitamin E@200 mg/l and vitamin C @200 mg/l respectively. Better performance was observed in antioxidant supplemented groups in terms of body weight gain, feed intake and feed conversion ratio, livability, gross profit and physico-chemical profile of breast muscle excluding shear force value while the carcass traits and proximate composition of breast muscle except for crude protein percentage were not affected.
