摘  要:
单宁是一种结构较为复杂的植物次生代谢产物,其种类繁多且广泛存在于自然界的植物中。大量研究表明,饲粮中添加适量的单宁可降低反刍动物瘤胃甲烷排放,增加过瘤胃蛋白及酶的合成,从而提高动物生产性能,同时在替代抗生素饲料添加剂及调节机体免疫等方面有着巨大的潜力。然而,饲粮中单宁的有效添加剂量及相关作用机理尚不明晰,因此,本文在综述单宁种类和生物学功能的基础上,重点论述了单宁对反刍动物瘤胃微生物和免疫功能的影响,以期为单宁作为植物提取物在动物营养及抗生素减量化应用方面的深入研究提供理论参考。

摘  要:
Tannin is a secondary metabolite with a complex structure,it has a wide variety and in nature it is widely found in plants. A large number of studies have found that adding low concentrations of tannin into animal diets can reduced methane emissions,increase rumen-bypass protein and enzyme synthesis,thus improve the animal performance,and have great potential in replacing antibiotic feed additives and regulate body immunity. However,the effective dosage of tannin in feed and its related regulation mechanism are not clear. Therefore,based on a review of the types and biological functions of tannins,this article focused on the effects of tannins on the rumen microorganisms and immune function of ruminants,and to provide a theoretical reference for the application of tannin used as a plant extract in animal nutrition and antibiotic reduction.[Chinese Journal of Animal Nutrition,2020,32(11):5059-5068]
