Abstract:
The aimed of this research is to determine the nutritional quality of bioconversion feed and productivity performance female kacang goats. This research used method a completely randomized design with 3 treatments and 5 replications. The treatments tried were P0 = Feed without the use of Lactobacillus casei (Lc); P1 = Use of 1 ml Lactobacillus casei (Lc)/kg feed; and P2 = Use of 1.5 ml Lactobacillus casei (Lc)/kg feed. The parameters observed included the quality of bio converted feed and goat productivity, including body weight gain, dry matter consumption, feed use efficiency, cutting weight, carcass weight, and carcass percentage. The composition of feed bio converted with Lactobacillus case is 15% corn cobs, 32% rice bran, 9% ground soybeans, 19% ground corn, 15% coconut meal, 4% cassava flour, 0.5% salt, 0.5% mineral mix, and 5% molasses. Based on the results of the analysis of variance, it was found that the treatment showed no significant effect (P > 0.05) on dry matter content (DM), feed organic matter, feed dry matter consumption, slaughter weight, and carcass weight, but had a significant effect (P <0.05) on crude fiber content, extract material without nitrogen, ash content, and efficiency of ration use; however, it had a very significant effect (P<0.01) on crude protein, crude fat, body weight gain, and carcass percentage. It can be concluded that feed bioconversion using Lactobacillus casei up to a level of 1.5 ml/kg feed can improve the feed quality and productivity performance female kacang goats.
