Fermentative profi le and losses in Sorghum bicolor silages from different cultivars.

Sorghum bicolor is a type of tall sorghum, higher than two meters, mainly characterized by having sweet and juicy stalk. For silage production, it has an easy cultivation, high yield, lower moisture demand and particularly good quality fermentation of the produced silage, achieved through adequate concentration of soluble carbohydrates, which are essential for lactic fermentation, without additives to stimulate fermentation, and nutritional value similar to corn silage (Goncalves and Borges, 1997). Inside this context, we aimed to evaluate the fermentative profi le and losses in Sorghum bicolor silages from different cultivars and two different periods of cultivation.
