Abstract

This study evaluated the effect of Leucaena leaves (Leucaena laucochepala) supplementation on the digestibility of Ettawa Crossbred goats. Twelve Ettawa Crossbred goats during the lactation period divided into six groups were allocated in a group randomized design with two treatments and six replicates (two goats per replicate). Treatments consisted of T1 in the form of 100% Leucaena leaves and T2 in the form of 50% Leucaena leaves and 50% concentrate. This study began with the preliminary stage, adaptation stage, data collection and analysis. Data from this study were tabulated using Microsoft Excel program, then analyzed using double T-test analysis with Randomized Group Design. The results showed that the 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 leaves + 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 effects (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 feed digestibility value.
