Enzymes as silage additive. Effect on fermentation quality, digestibility in sheep, degradability in sacco and performance in growing cattle

Fungal glucose oxidase and cellulase were used as silage additives in laboratory (25 l), pilot (3 m3) and farm scale (250 t) silos. In 3 m3 scale silos, pH and the concentration of acetic acid were lower and the concentrations of lactic acid and sugars were higher in the enzyme treated than in untre...
