Effect of fermented leucaena (Leucaena leucocephala) leaf water extract supplementation in drinking water on broiler carcass characteristics

This study aimed to determine the broiler carcass yield from the addition of fermented lamtoro (Leucaena leucocephala) leaf extract to drinking water. The study used a Completely Randomized Design (CRD) consisting of 4 treatments and 5 replications, each replication consisting of 4 broiler chickens. The treatments in the study were drinking water without fermented lamtoro leaf water extract (P0), 2% fermented lamtoro leaf water extract in drinking water (P1), 4% fermented lamtoro leaf water extract in drinking water (P2), and 6% fermented lamtoro leaf water extract in drinking water (P3).  The variables observed were carcass, commercial carcass cuts, and physical composition of broiler breast. The results showed that the slaughter weight and carcass weight of broilers in treatments P1, P2, and P3 were higher (P<0.05) than treatment P0. The carcass percentage was not significantly different (P>0.05) between treatments. Commercial cuts of broiler carcasses in treatments P1, P2, and P3 were better (P<0.05) than treatment P0. The percentage of meat and fat from broiler breasts in treatments P1, P2, and P3 was higher (P<0.05) while the percentage of broiler breastbone was lower (P<0.05) than treatment P0. It can be concluded that treatments P1, P2, and P3 produced better carcasses, commercial carcass cuts, and physical composition of broiler breasts than treatment P0.
