Resumen
Descripción
The silage is based on spontaneous lactic fermentation, where under anaerobic conditions the soluble carbohydrates are fermented with lactic acid production and rapid decrease in pH. Corn is considered the best forage to be ensiled due to its high dry matter productivity, low buffer 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; França et. al. 2012). The objective of this work was to evaluate the changes on concentrations of organic acids in corn silage occurring during the use of crude glycerin.
