微生态制剂对动物肠道健康影响的研究进展

Advances in research about effects of microecologics on intestinal health of animals

动物肠道是进行消化和吸收营养物质的主要部位,肠道中有大量复杂多样的微生物通过或者定殖,对维持胃肠系统的动态平衡发挥着至关重要的作用,肠道微生物及其代谢对动物机体生理健康发挥着关键性影响和调控作用。微生态制剂是一种安全、高效的生物类饲料原料,通过调节宿主体内的微生态结构,从而增强动物机体免疫力,促进动物生长和提高饲料转化率等。综述了近几年微生态制剂对动物肠道健康影响等方面的研究概况,以期为微生态制剂在畜产业生产上的合理应用提供参考。

The intestinal tract of animals is the main site for digestion and absorption of nutrients.There are a large number of complex and diverse microorganisms in the intestine through or colonization,which plays an important role in maintaining the dynamic balance of gastrointestinal system.Intestinal microorganisms and their metabolism play a key role in the physiological health of animals.Microecological preparation is a safe and non-toxic biological feed additive.It has various functions such as promoting the growth and development of animals and improving the immunity of animals by regulate the microecological structure in the host.In this paper,the research about effects of microecological preparations on intestinal health of animals in recent years were reviewed in order to provide a reference for the rational application of microecological agents in livestock production to promote livestock health and improve production performance.
