This study was carried on the effect of superliv feeding on commercial broiler. Superliv is an herbal product and useful growth promoter for the broiler due to its lever tonic. The experiment was conducted at the poultry farm of C. S. A. Univ. of Agri. & Tech., Kanpur. The experiment was carried out on 60 days old broiler chicks were divided randomly into four groups of 15 chicks in each group. The birds of group G1 were served as control while group G2, G3 and G4 were received 0.1, 0.2 and 0.3 per cent of Superliv, respectively. Feeding trials were conducted for 5 weeks. First three-week broiler was fed broiler starter and letter was fed broiler finisher ration. The weekly body weight (gms) per broiler chicks up to fifth week of age is weighed as 1036.66 +83.20, 1075.33+54.49, 1130.00 +67.11 and 11.43.33 + 46.54, respectively, body weight gain (gms) during I, II, III, IV, and V week of age were 992.58, 1028.11, 1089.25 and 1106.05 respectively, Weekly feed consumption (gms) per broiler chicks up to Vth week of age were 2314.58, 2326.78, 2329.40 and 2365.92 respectively, feed conversion efficiency up to Vth week of age were 2.15, 2.12, 2.05 and 2.03 respectively, higher profit per broiler chicks was found Rs.11.14, 12.49, 14.63 and 14.89 respectively, and benefit cost ratio was found 0.71, 0.72, 0.74 and 0.76 in group G1, G2, G3, and G4, respectively. Thus, it can be concluded that the superliv feed supplement at 0.3 per cent level or group G4 was beneficiary in broiler chick ration. It can help on the increase of growth rate, body weight gain, F.C.R. and benefit cost ratio
