Basilisk silage in laboratory bags. Entirely random lining was used, with five treatments: 0; 10; 20; 30 and 40g/kg rice meal, based on natural grass matter. The values of losses by gas and effluents were reduced linearly in 0.11 and 0.39g/kg DM, while recovery of dry matter increased linearly in 0.32g/kg DM. There was quadratic behavior for pH values and linear decrease for the values of N-ammoniacal and buffering power estimated in 1.1 and 5g/kg DM. Concentrations of acetic, butyric and propionic acids were reduced linearly in 0.1; 0.008 and 0.006g/kg DM, while lactic acid increased linearly in 0.5g/kg DM. Each 1g/kg rice meal promoted linear increase of 4.3; 1.8; 7.1 and 7.0g/kg dry matter levels, crude protein, ethereal extract and total digestible nutrients and linear decrease of 6.9; 4.3 and 2.6g/kg DM of fiber in neutral detergent, fiber in acidic detergent and hemicellulose levels. Inclusion of 10g/kg rice meal already ensures lowering losses by gas and effluents, increase in dry matter recovery, allowing improvements on the fermentative profile and the chemical composition of silage.</p><p></p> 2018-12-26 03:54:15 byproduct effluent fermentation nutrition value
