The effect of pandan leaf extract in drinking water on the physical carcass composition of broiler chickens

Productivity and health of broiler chickens are key aspects that can be improved through the use of feed additives, one of which is the utilization of pandan leaf extract. The objective of this study was to determine the physical composition of broiler carcasses when supplemented with pandan leaf extract in drinking water. Using four treatments and five replications and each replication consisting of five broiler chickens. The treatments applied in this study were as follows: Treatment PLE 1: drinking water without pandan leaf extract; treatment PLE 2: drinking water with 3% pandan leaf extract; treatment PLE 3: drinking water with 6% pandan leaf extract; and treatment PLE 4: drinking water with 9% pandan leaf extract. The results of the study showed that treatments PLE 2 and PLE 3 significantly (P<0.05) increased carcass weight (CW), slaughter weight (SW), meat percentage (MP), and carcass percentage (CP), while reducing fat percentage including skin (FS), compared to treatment PLE1. Meanwhile, treatments PLE 4 significantly (P<0.05) reduced SW and CW. Based on this study, it can be concluded that the addition of 3% and 6% pandan leaf extract in drinking water can increase slaughter weight (SW), carcass weight (CW), carcass percentage (CP), and meat percentage (MP), while reducing the percentage of fat and skin (FS) in broilers. However, the addition of 9% pandan leaf extract in drinking water decreased SW and CW compared to the control treatment.
