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
