- Abstract
Degradability and in vitro gas production of alternative energy sources in ruminant feed. The in vitro fermentation pattern of diets composed of corn meal, rice bran, parboiled rice bran and their associations was studied in different proportions in the concentrate portion in ruminants diets. Up to 12 hours of incubation, gas production was higher (p < 0.05) for the treatments with rice bran (FAI) and parboiled rice bran (FAP); however, after 96 hours, the treatment with 100% corn meal (FM) produced more (p < 0.05) gases (379.41 mL g DM-1). Total degradability of dry matter (DM) and organic matter (OM) were higher (p < 0.05) for treatments FAI and FAP up to 12 hours; however, after 96 hours of incubation the total degradability of DM and OM was higher (p < 0.05) for the FM treatment (90.46 and 91.08%, respectively). The nutritional potential of rice bran or parboiled rice bran was confirmed in the diet of ruminants, as it provides a higher fractional rate of in vitro gas production (12.39 and 13.17 mL h-1) and faster degradation of DM and OM in initial times.
