Application and Outlook of Exogenous Enzymes in Ruminants
摘要
Abstract
Ruminants can convert forage 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 di-gestibility of plant cell walls. The digestibility of plant material is low at present. It is potential to improve plant fiber digestibility that supplementing ruminant diets with exogenous enzymes, and thus improve the efficiency of feed utilization. This review summarized the application status, modes of action, and development directions of exogenous enzymes. The effects of exogenous enzymes in ruminants had variability, which might be due to enzyme array, addition level, addition mode, substrate type and host productive level. Exogenous enzymes ac-ted in different environments, such as before feeding, in rumen and post-rumen, however, the exactly mecha-nism needed more investigation. In general, exogenous enzymes that used to enhance the feed digestibility would be one of the most important ruminant additives in the future, though they had variability at present.关键词
