Abstract

Summary Various cellulolytic preparations were used to produce changes in fermentation and cellulose content of ensiled forages. Alfalfa, barley, or bagasse was mixed with enzyme preparations and ensiled in fruit jars in three trials. All silages had a characteristic color, odor, and pH of good-quality silage. Apparent cellulose hydrolysis occurred in the enzyme-treated silages (maximum of 29%) compared to the control silages, with a concomitant increase in titratable acidity and reducing substances. Cellulolytic activity was relatively stable in the silage. The effect of these enzyme preparations on ensiled forage needs to be evaluated by animal performance before their full potential can be determined.
