Abstract

Rice bran is potential farm byproduct which can be used for poultry feed because of its abundance in Indonesia. In other side, rice bran contains high crude fiber and easy to rancid which can be solved by fermentation. The aims of study are to prove the potency of Actinobacillus sp. ML-08 in decreasing crude fiber and increasing nitrogen free extract (NFE) content of fermented rice bran. The research design used complete randomized design. There were six treatments: P0: rice bran only as negative control, P1: rice bran and molasses 2% as positive control, P2, P3, P4, P5 also rice bran and molasses 2% with addition of Actinobacillus sp. ML-08 as fermentation starter doses 5%, 10%, 15%, and 20%. Proximate Analysis was done after 7 days of facultative anaerobes fermentation. Research result showed significant different (p<0.05). The lowest concentration of crude fiber content was 17.58% in P2 decrease from originally (P0) 22.17% and the highest concentration of nitrogen free extract (NFE) showed 42.57% in P2 from originally (P0) 34.97%. The conclusion of this research is Actinobacillus sp. ML-08 can decrease crude fiber and increase nitrogen free axtract (NFE) in rice bran so it can be used to make quality poultry feed effeciently.
