Digestibility of Complete Feed with Addition of Vitamin E in Female Bligon Goat
Twelve female Bligon goats, age 18 m and with body weight of 18.75 ± 2.51 kg, were used in this experiment to determine the effect of vitamin E addition on complete feed digestibility. The animals were placed in individual metabolism cage and divided into three groups, namely, R0, diet without addition of vitamin E as a control (basal diet); R1, basal diet +0.75 g (17 IU) dl-α-tocopherol acetate (vitamin E); and R2, basal diet +1.125 g (20 IU) dl-α-tocopherol acetate (vitamin E). This experiment was performed for 6 weeks of diet adaptation and 12 d of collection period. During collection period, the amount of feed offered, refusal feed, feces, and urine excreted were recorded, and samples were taken for nitrogen analysis. Nitrogen intake, fecal nitrogen excreted, and urinary nitrogen excretion were calculated. The data obtained were analyzed by analysis of variance using one-way completely randomized design followed by Duncan’s multiple range test (DMRT). The result showed that addition of vitamin E increased dry matter (DM), organic matter (OM), ether extract (EE), crude fiber (CF), and nitrogen-free extract (NFE) intake significantly. There were no significant differences of digestibility of dry matter, organic matter, crude fiber, and nitrogen-free extract as an effect of vitamin E addition, while crude protein digestibility increased significantly. It could be concluded that addition of vitamin E to the diets of female Bligon goat at the level of 17 IU was recommended.
