Losses in wilted Tifton 85 grass silage with different aditives.

Because the seasonality in forage production it is necessary to preserve roughage in the summer in order to use it during the dry season. Silage of wilted Tifton 85 grass may be used for this purpose, but its conservation is difficult. Secondary fermentation, high effluent production and aerobic deterioration can increase the dry matter loss from 7 to 40% (McDonald et al., 1991). The use of additives in tropical grass silages can overcome part of these limitations caused by the high moisture content, low soluble carbohydrate and the great buffering capacity. According to Woolford (1984), these factors inhibit the occurrence of an adequate fermentative process and impair a better quality silage production. In order to decrease these losses, several practices have been used, but they have to be evaluated. The use of citrus pulp and bacterial inoculants increases the lactic acid production, accelerate the pH drop, improve preservation and reduce losses (Pitt, 1990). The objective of this work was to determine the losses in wilted Tifton 85 silage with the addition of enzymatic bacterial inoculants and of citrus pulp
