摘要：Antibiotics have been used in poultry to improve growth performance but due to their side effects European Union has banned use of antibiotic as growth promoters in animal feed in 2006. Such situations has resulted in search for natural and safe alternatives, therefore, this study was undertaken to compare the efficacy of commercial herbal growth promoter as dietary inclusion on performance, minor body parts weight and immune response in broiler. A total of 120 healthy day old Hubbard chicks of uniform body weight were divided into 12 experimental units of 10 chicks each. These experimental units were further allotted to 4 treatment groups (T1, T2, T3 and T4) such that each treatment received 3 replicates. Group A was fed ration without supplementation of commercial herbal products i.e. control whereas group B, C and D were fed ration supplemented with commercial herbal products i.e. Bio-Mix, Respecine and A one Formula respectively each @ 100 g/ 50 kg of commercial feed. Each experimental unit of the chicks was reared in a separate pen. The birds were kept under similar managerial conditions. Feed intake, weight gain and FCR was better in group C fed respecine supplemented diet (P<0.05) whilst immune response against ND and IBD was higher in group B fed diet supplemented with Bio-mix (P<0.05) whereas dressing percentage, liver weight, heart weight, gizzard weight, spleen weight, pancrease weight and intestinal weight were not significantly affected by commercial herbal growth promotors (P>0.05). Use of various commercial herbal growth promoters in the ration exhibited an increase in the profit margin of broilers. Broilers reared on respecine fetched maximum profit as compared to other groups.
