植物活性多糖的生理功效及其在反刍动物生产中的应用研究进展

植物活性多糖作为饲料添加剂，因具有来源广泛、安全高效、无毒副作用、生物活性作用效果突出的特点，而备受关注。它不仅可以增强机体免疫力、抗氧化、抗肿瘤、抗病毒、降血脂的功能，还可以提高反刍动物的生长性能、改善瘤胃发酵模式、维持肠道微生态平衡、提高精液保存效果、增强疫苗免疫活性、缓解机体免疫应激。本文主要阐述了植物活性多糖的生物学功能及其作用机制，综述了近些年其在反刍动物安全生产中的应用，并对其应用前景进行展望，以期为植物活性多糖在反刍动物安全生产方面的理论研究及其进一步应用提供参考。

Physiological function of plant active polysaccharides and research progress on its application in ruminant production

Plant active polysaccharides, as feed additives, have attracted much attention because of their extensive sources, safety, high efficiency, non-toxic side effects and outstanding biological activity effect. It can not only enhance the body immunity, anti-oxidation, anti-tumor, anti-virus, lowering blood lipid functions, but also improve the growth performance of ruminants, ameliorate the rumen fermentation mode, maintain the intestinal microecological balance, improve semen preservation effect, enhance the immune activity of vaccine, relieve the immune stress of the body. In this paper, the biological function and mechanism of plant active polysaccharides were expounded, and the application of plant active polysaccharides in ruminant production safety in recent years was reviewed, and its application prospect was prospected, in order to provide reference for theoretical research and further application of plant active polysaccharides in ruminant production safety.
