摘要: 单宁是一类广泛存在于植物中的多酚化合物,因其涩味降低反刍动物采食量,故通常被归类为饲料中的抗营养因子。近年来,研究发现单宁可与蛋白质结合,抑制蛋白质被瘤胃过度降解,增加了蛋白质在后肠道的消化吸收,提高了反刍动物对氮元素(N)的利用率。此外,研究表明单宁在调控瘤胃发酵和抑制甲烷排放方面表现出积极作用。本文主要综述了单宁对反刍动物生产性能、瘤胃发酵和微生物区系的影响,旨在为其应用于反刍动物健康养殖提供合理的理论参考依据。

Abstract: As a class of polyphenolic compounds, tannins are widely distributed in various plants, and were generally classified as anti-nutritional factors in ruminants' feed due to their astringency taste which reduce the feed intake of animals. In recent years, studies have found that tannins can bind to proteins, which prevent proteins from being excessively degraded in the rumen, and increase the digestion of proteins in the hindgut, further improves the utilization of nitrogen (N) in ruminants. In addition, studies have shown that tannins play active roles in regulating rumen fermentation, inhibiting methane emissions, and possess certain antimicrobial capabilities. In this paper, the effects of tannins on ruminant production performance, rumen fermentation and microflora were reviewed in order to provide theoretical reference for its rational use in ruminant healthy farming.

Key words: tannins, ruminant, production performance, rumen fermentation, microflora
