Several types of enzymes have been used as silage additives to improve the nutritive value of corn silage. One of them are proteases, which accelerate the fermentation process. The addition of exogenous protease enzymes at corn harvesting can increase starch degradability in the rumen by acting on the prolamin–starch matrix. However, it has been reported that high level of proteases may stimulate the growth of yeasts in corn silage.
