Technical Abstract: Cellulase can decrease cell-wall concentration and subsequently increase the soluble and rapidly digestible portion of silage dry matter. This study determined the effects of cellulase alone or combined with bacterial inoculant or formic acid on intake and digestion of orchardgrass (Dactylis glomerata L.) and alfalfa (Medicago sativa L.) silages. Intake and in vivo digestibilities were determined on lambs and in situ digestion kinetics were determined on cows. Cellulase and formic acid increased dry-matter intake by 13% compared with control silage when averaged across species. Because of extensive cell-wall degradation by cellulase during ensiling, cellulose intake and digestibility were lower for treated than for control silages. Additionally, extent of cellulose digestion was 37% lower in cellulase and formic acid treated silage than in the control.
