摘要
植物单宁是一种酚类次生化合物,广泛存在于植物体内。由于其活泼的化学性质及特殊的分子结构,导致单宁会对反刍动物产生抗营养作用,因此,单宁长期被贴以抗营养物质的标签。然而近些年的研究表明,日粮中添加一定比例的单宁会使反刍动物具有过瘤胃蛋白保护、提高产奶量、抑制瘤胃膨胀病、抑制寄生虫病等作用,这表明单宁对反刍动物的作用取决于饲料中单宁的含量。本综述分析了单宁对反刍动物的不利和有利影响,阐述了单宁的应用情况,旨在为合理利用植物单宁提供理论依据和技术参考。
Plant tannin is a kind of phenolic secondary compound,which is widely found in plants.Due to its active chemical properties and special molecular structure,tannins can produce anti-nutrition effects on ruminants,therefore,tannins have long been labeled as anti-nutritional substances.However,recent studies have shown that adding a certain proportion of tannin to ruminant diet can protect rumen protein,increase milk yield,prevent ruminal bloat,inhibit parasitic diseases and so on,which suggest that the effect of tannins on ruminants depend on the content of tannins in the diet.This paper summarizes the adverse and beneficial effects of tannin,and the application of tannin as well,on ruminants to provide theoretical basis and technical reference for rational utilization of plant tannin.
