摘要:

单宁又称单宁酸、丹宁、鞣酸,是天然、无毒的一类大分子多酚类物质,其化学性质活泼,具有多种生物学活性。日粮中添加适量单宁能提高牛羊生产性能,减少机体甲烷排放,减少尿素氮含量,降低瘤胃蛋白降解率,调节瘤胃微生物区系,改善肉品质,在反刍动物养殖领域的应用前景十分广阔。介绍了单宁的理化特性,综述了单宁对牛羊生产性能、氮代谢、瘤胃微生物区系及其代谢产物影响方面的研究进展,以期为单宁在畜牧生产中的应用研究提供参考。

Abstract:

Tannin, also known as tannic acid, is a natural, non-toxic group of macromolecular polyphenols with active chemical properties and a range of biological activities. Dietary supplementation of suitable level of tannin can improve the production performance, reduce methane emissions, decrease urea nitrogen content, lower rumen protein degradation rate, regulate rumen microbial flora, and improve meat quality of cattle and sheep. In the area of ruminants farming, it has a wide range of potential applications. In this paper, the physical and chemical properties of tannin are introduced, and the research progress of the effects of tannin on production performance, nitrogen metabolism as well as rumen microbial flora and their metabolites in cattle and sheep are reviewed, in hoping to provide references for the application of tannin in livestock production.

Key words: tannin, cattle and sheep, production performance, microbial flora, methane emission
