Ruminant can convert plant biomass that human can’t use directly to high quality protein-meat and milk, which is important to agriculture and human society. However, the conversion efficiency is dependent on digestibility of plant cell walls. The conversion efficiency is low as well as the digestibility of plant material at present. The enzyme application method can vary in a wide range from applying to forage at harvesting, at ensiling, at feeding and the portion of feed which is mixed with enzyme may also vary from to forage to concentrate to a part of totally mixed rations. The positive effects of exogenous enzymes enzymes on growth production of dairy cattle have been demonstrated definitively, but the information required to improve the consistency and increase the magnitude of these responses is unfortunately still lacking. Comparisons between experiments are exceedingly difficult, because many enzyme products are poorly defined. Further, several studies have shown that over-application of enzyme is possible, such that increased application costs are not recovered by corresponding improvements in animal performance. In general, exogenous enzymes that used to enhance the feed digestibility will be one of most important ruminant additives in future, though they have variability at present.
