This research aimedto evaluate the effects of burning and the use of dry additive on the sugarcane silage fermentative pattern. Six treatments were tested: natural or burnedsugarcane, associated to three supplementation levels: 0, 50 or 100 g/kg ofdehydrated corn grain, cob, and straw (CGCS) based on forage fresh mater. Thefollowing response variables were determined in the forage: DM, CP, acid detergentinsoluble nitrogen (ADIN), NDF, ADF, cellulose, hemicellulose and lignin concentrations.Considering the fermentative traits, soluble carbohydrate levels, bufferingcapacity, pH, ammonia nitrogen and ethanol levels were measured. The CGCS inclusionincreased DM concentration and slightly reduced ethanol and N-NH3levels in silages, but did not affect pH or yeast growth. Burning reduced DMand N-NH3 concentration, as well as increased ethanol levels andyeast growth. Ethanol production in sugarcane silage was not controlled by usingdry additive or burning.
