Physical composition of broiler carcasses fed with fermented herbal medicine in commercial rations

The study aimed to determine the effect of fermented herbal medicine in commercial rations on the physical composition of broiler carcasses has been carried out for 35 days, using 80 broilers. The experimental design used was a completely randomized design (CRD) consisting of 4 treatments and 4 replicates. The treatment of giving fermented herbal medicine in broiler commercial rations are: A: without fermented herbal medicine; B: 2% fermented herbal medicine; C: 4% fermented herbal medicine; and D: 6% fermented herbal medicine. The observed variables were: slaughter weight, carcass weight, carcass percentage, meat percentage, bone percentage, and subcutan fat percentage including skin. The results showed that the percentage of meat in treatment B, C, and D was significantly (P<0.05) higher than that of the control by 3.74%, 7.38%, and 5.11% respectively, and the percentage of subcutaneous fat including skin was significantly (P<0,05) lower than that of the control by 16.10%, 29.98% and 31.99% respectively. The slaughter weight, carcass weight, carcass percentage, and bone percentage were not significant different. Based on the results of this study, it can be concluded that the administration of fermented herbal medicine by 2-6% can increase the percentage of meat and decrease the percentage of subcutaneous fat including skin, but have no effect on the sloughter weight, carcass weight, carcass percentage and bone percentage of carcass broiler aged 35 days.
