摘要：

This study examined the production of com silages with low or high lactic acid concentrations, provided by the addition of formic acid (0.5%), molasses (5%) or microbial inoculant (homofermentative lactic acid bacteria, 10 g/tonne). After the fermentation period, sheep were fed the silages to determine true and apparent digestibility of the organic matter and microbial protein synthesis. The experiment were carried out with four KivircikxMorkaraman sheep, 1.5 years old, fixed with cannula in their rumen and duodenum. Lactic acid concentrations were significantly higher in silages treated with enzyme or molasses compared to other specific treatments. Acetic acid concentration was highest in silage treated with formic acid, and lowest in silage treated with molasses (P < 0.05). The by-pass of crude protein was highest in silage treated with formic acid. (c) 2005 Elsevier B.V. All rights reserved.
