Evaluation of Lamtoro Leaf (Leucaena Leucocephala (Lam.) De Witt.) Supplementation in Feed on Nutritive Value and Digestibility in Lactation Period Peranakan Ettawa Goats in Vivo a) Lecturer of Faculty Animal Science, Brawijaya University, Malang 65145, Indonesia Abstract This study evaluated the effect of Leucaena leves (Laucaena laucochepala) supplementation on the digestibility of Ettawa crossbreed goats. Twelve Ettawa crossbreed goats during lactation period divided into 6 groups were allocated in a group randomized design with two treatments and six replicates (two goats per replicate). Treatments consisted of control (T0) in the form of 100% Leucaena leaves and (T1) 50% Leucaena and 50% concentrate. This study began with the preliminary stage, adaptation stage, data collection and analysis. Samples of feed given, the amount of feed given, the amount of leftover feed given and feces samples from each individual goat were recorded every day for data collection. Data from this study were tabulated using Microsoft Excel software program, then analyzed using T test analysis and Randomized Group Design. The results showed that the CFD (Crude fiber digestibility) value had a significantly different effect (P<0.05), Leucaena leaves high Crude Protein content can affect digestibility to be higher than T1 which is composed of 50% Leucaena + 50% concentrate. ADF digestibility value showed no significant difference (P>0.05). NDF digestibility showed no significant difference (P>0.05). Hemicellulose digestibility showed no significant difference (P>0.05). The digestibility of organic matter showed no significant difference (P<0.05). Dry matter digestibility showed significantly different effect (P<0.05). The digestibility value of crude protein showed a significantly different effect (P<0.05). The results of the study can be concluded that Leucaena leaves supplementation can increase the digestibility value.
