Abstract
Rice bran (RB) and deoiled rice bran (DORB) is a by product of rice-milling industry which is cheap and using as animal feed throughout the world. Considering limitation like higher content of fiber and lower availability of few micronutrients including phosphorus they were fermented anaerobically using inoculum from rumen of a sheep to get fermented value added feed ingredient. Initially they were fermented for 12 hours at 390C giving 10, 20, 30, 40, 50 and 60% moisture and addition of 10% rumen innoculum. Then DORB was fermented for 24, 48 and 72 hours at 390C and giving 10% innoculate but different moisture level (10, 20, 30, 40, 50 and 60%). Before and after fermentation they were analysed for proximate components, NDF, total-P, inorganic-P and phytate-P. Fermentation of RB and DORB for a period of 12 hours decreased pH, CF, NDF and phytate-P, but increased inorganic-P content (p<0.05). Further fermentation of DORB also showed similar result for lowering pH, CF, NDF and phytate-P, but increased inorganic-P (p<0.05). So, innoculation of rumen microbes reduce phytate-P and fiber content (CF and NDF) of RB as well as DORB. Further research is needed for confirmation and bioavailability in nonruminant animals
