Microbiological evaluation of aerobic stability of corn silage with increasing levels of glycerin.

Corn is considered the best forage to be ensiled due to its dry matter content, low buffering capacity and adequate levels of soluble carbohydrates for fermentation (McDonald et al., 1991). The use of crude glycerin as ingredient in ruminant concentrates has been studied in the last years (Gonçalves et al., 2006), but not as silage additive. When used as additive it can improve energy density and decrease total dry matter content. However there is no information about silage stability after silo opening. The objective of this work was to evaluate the changes occurring on microbial populations in corn silage containing different levels of glycerin after air exposition.
