Effect of the addition of fermented Lamtoro leaf water extract (Leucaena Leucocephala) in drinking water on the performance and histology of the broiler intestine

This study aims to determine the productivity of broilers fed with water extract of lamtoro leaves (Leucaena leucocephala) fermented through drinking water. This study used a Complete Random Design (RAL) consisting of 4 treatments and 5 replicates, each replicate consisted of 3 broiler chickens. The treatment provided was 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 the performance and histoology of the broiler intestine. The results of the broiler study that was given fermented lamtoro leaf water extract at doses of 2%, 4%, and 6% had a real effect (P<0.05) on the final weight, body weight gain, villi height, and small intestine crypta depth. However, there was no significant difference (P>0.05) in ration consumption, drinking water consumption, and FCR. It can be concluded that the addition of fermented lamtoro leaf water extract in broiler drinking water can improve the performance and histology of broiler small intestine.
