One hundred and ninety two, day old chicks were randomly distributed in eight treatments of two replications in each and reared upto six weeks on standard managemental conditions. The powder of vitamin E and selenium was added to the basal diet @ 0, 20 mg and 40 mcg, 25 mg and 50 mcg, 30 mg and 60 mcg, 20 mg and 40 mcg, 25 mg and 50 mcg, 30 mg and 60 mcg, 0 in treatment groups T1 to T8 respectively. The birds of treatment groups T1, T2, T3 and T4 were immunized against RD and IBD disease while the birds of the groups T5, T6, T7 and T8 were not immunized against any disease. The average body weights at 6th week of age were 2054.58 29.99, 2060.41 57.99, 2049.08 43.88, 2063.61 34.92, 2054.79 62.24, 2111.54 47.81, 2143.91 44.14 and 1962.35 49.38 g in the treatment groups T1 to T8 respectively. The body weight gain and feed efficiency differed significantly (P<0.01) among all the treatment groups and it was better in vitamin E and selenium treated and non vaccinated groups than vaccinated and control groups. It was concluded that the supplementation of vitamin E and selenium in the diet has beneficial effect on body weight and feed efficiency of broilers.
