Enzyme assisted ensiling of alfalfa with enzymes by solid substrate fermentation.

A crude enzyme preparation, obtained by solid substrate fermentation (SSF) with a Gliocladium spp. and added at the 5% level to wilted or non-wilted alfalfa, improved the fermentation characteristics and stability of alfalfa silages as effectively as commercial preparations, Novo-Nordisk Celluclast 1.5 L and Viscozyme 120 L, applied at the 0.025% level. The effective dose of the crude enzyme costs about one-fourth of the cost of the commercial enzymes.
