Two hundred, day old Anak-2000 broiler chicks were divided into four groups of 50 chicks each. Group I was kept as control, group II was fed with antibiotic STAFAC*20 @ 50g/100 kg of feed, group III was fed with Probiotic BIOVET*YC @ 50g/100 kg of feed and group IV was fed with a combination of antibiotic STAFAC*20 and probiotic BIOVET*YC @ 25g each/100 kg of feed. There was no significant difference among different groups with regard to feed intake, body weight gain and feed conversion efficiency. The total protein consumption and protein efficiency ratio was also similar in all the groups.
