Milk lactose, specific gravity and mineral of etawa dairy goat fed with palm kernel cake based concentrate, tithonia (Tithonia diversifolia), sweet potato leaves (Ipomoea batatas L) and gamal (Gliricidia sepium)

Abstract

This study aims to evaluate the milk lactose, specific gravity, and mineral of Etawa Crossbreed Dairy Goat (ECDG) fed with palm kernel cake-based concentrate (PKCC), tithonia (Tithonia diversifolia), sweet potato leaves, (Ipomoea batatas L.), and Gamal (Gliricidia sepium) as a source of roughage. The design of the experiment used was a completely randomized design (CRD) with four treatment rations and four replications. Treatment formulations are as follow A). 100% basal ration (BR); B). 50% BR + 50% Concentrate Based Palm Kernel Cake (CPKC) + tithonia; C). 50% BR+ % CPKCC + sweet potato leaves; D).50% BR + 50% CPKC + Gamal (Gliricidia sepium). The ratio of concentrate and roughage is 50:50. The concentrate ratio consists of 30% palm kernel cake, 40% tofu waste, 20% rice bran, 9 % corn, and 1% mineral. The parameters were milk lactose, specific gravity, and mineral of milk. Data were analysed by Analysis of Varian (ANOVA) and DMRT (Duncans Multiple Range Test) according to Steel and Torrie (2002). The results showed that the treatment had no significant effect (P> 0.05) on lactose, specific gravity, and mineral of milk. From this study, it can be concluded that the use of PKC, titonia, sweet potato, and gamal can replace basal ration without affecting the quality of milk (lactose, specific grafity and mineral)
