A study was conducted to evaluate the effect of supplementation of Vitamin E and Selenium in broiler diets on growth performance and biochemical indices. A total of 252- day old commercial broilers chicks were divided into nine treatments (two replicates in each) with 14 chicks per replicate. They were fed ad libitum basal diet T0 (control). The supplementation in different groups viz. T1 (Se 0.1 mg/kg), T2 (Se 0.2 mg/kg), T3 (Vitamin E 100 IU/kg), T4 (Se 0.1 mg/kg and Vitamin E 100 IU/ kg), T5 (Se 0.2 mg/kg and Vitamin E 100 IU/kg), T6 (Vitamin E 200 IU/ kg), T7 (Se 0.1 mg/kg and Vitamin E 200 IU/kg) and T8 (Se 0.2 mg/kg and Vitamin E 200 IU/kg). Weekly body weights, daily feed consumption and mortality were recorded. At the end of experiment, blood samples of two chicks from each replicate were taken. The results indicated that supplementation of Vitamin E or Selenium or both in different combinations helped in improving the body weight gains. The biochemical indices indicated decrease in total protein levels in birds receiving only Selenium as compared to control but there was no significant change in albumin levels. With supplementation of combination of Vitamin E and Selenium there was improvement in total protein levels indicating a synergistic effect of Vitamin E and Selenium in protein synthesis by liver. The results of present study suggested that the supplementation of Vitamin E and Selenium is beneficial for overall growth performance of broilers.
