Cinética de fermentação ruminal in vitro, composição química e perfil de ácidos graxos da silagem de bagaço de laranja com fubá de milho In vitro rumen fermentation kinetics, chemical and fatty acids composition of orange peel silage with corn meal

The objective of this study was to evaluate the effects of corn meal in silage orange peel in natura. The experiment has adopted a completely randomized, with four treatments (corn meal levels) and four replications. There were used experimental silos made of bucket of 12 L. Silos were opened at 90 days after ensiling, and evaluated the gases and effluent losses, pH, chemical composition, volatile fatty acids (acetic, propionic, butyric, valeric, isovaleric), and in vitro gas production. The dry matter (DM), ether extract (EE), non-fiber carbohydrates (NFC), and organic matter showed a linear increase with the inclusion of corn meal. The contents of neutral detergent fiber (NDF), acid detergent fiber (ADF) and crude protein (CP) decreased with increasing proportion of corn meal. Regarding the rumen
