Performance of Growing Goats Fed Panicum maximum and Leaves of Gliricidia sepium

Abstract
Thirty female goats of local breed (mature weight 28 kg), weighing 11 to 18 kg, were used in a growth experiment with the objectives to evaluate the effect of different levels of Gliricidia sepium leaves in a diet of Guinea grass (Panicum maximum) on feed intake, weight gain and apparent digestibility. The goats were allotted to five treatments, consisting of 5 levels, 0 (GL-0), 20 (GL-20), 30 (GL-30), 40 (GL-40) and 50% (GL-50) of Gliricidia sepium leaves in the diet based on the energy requirements of the goats. Another six female goats were used to study the digestibility of three dietary treatments, GL-0, GL-30 and GL-50, according to a double 3 3 Latin square arrangement. The crude protein (CP) content in Gliricidia was higher and the neutral detergent fibre (NDF) and acid detergent fibre (ADF) lower than in the Guinea grass. Increasing the amount of Gliricidia leaves resulted in similar intake of total dry matter (DM), organic matter (OM), NDF and ADF among treatments, but CP intake increased with increasing Gliricidia in the diet. The highest total DM intake was 3.0% of body weight in the GL-20 diet. The highest daily live weight gain was 43 g/day in the GL-30 diet. Inclusion of 30% of Gliricidia leaves improved the apparent DM, OM and CP digestibility compared to 0% or 50% inclusion. NDF and ADF digestibility declined with increasing levels of Gliricidia leaves in the diet.
