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
