摘要:The aim of the present study was to compare the efficacy of commercial herbal products on performance and immune response of broiler. One hundred twenty chicks were randomly divided into 12 experimental units (replicates) having ten chicks each. These experimental units were allotted to four treatment groups (T1, T2, T3 and T4) such that each treatment has three replicates. Group T1 was without supplementation of any commercial herbal product and served as control while the birds in group T2, T3 and T4 were supplemented with commercial herbal products i.e. Livol, Livotal, and Hepato promoter @ 1 ml per 2 liter water, 1 ml per 4 liter water, 1 ml per 4 liter water respectively. Supplementation of different commercial herbal products by water during 2-5 weeks of age significantly (P<0.05), improved weight gain (6.36-12.37%), consumed less feed (2.62-3.09%) improved feed conversion ratio (9.53-14.29%) and lowest mortality rate (3.33%). Supplementation of different commercial herbal products exhibited non-significant effect on dressed weight, relative weight of heart, liver, spleen, gizzard, pancreas and intestine of broiler. However, ND and IBD antibody titer was improved significantly (p<0.05) (T1). The birds using water supplemented with Hepatopromoter fetched the highest profit.
