摘要
本文研宄了动物肠道菌群与生产性能的关系。总结了国内外大量研究成果后发现,饲用微生物添加剂对仔猪、内鸡、肥育牛有较好的促生长作用和抗病防病作用。其主要作用机制为:维持肠道菌群正常化;调节营养物质的消化吸收;产生非特异性免疫调节因子及防止产生有害物质等。最后指出了微生物添加剂研究与应用中存在的问题,并提出了建议。
The paper studied the relationship of intestinal microbial flora to animal performance. In conclution with a lot of research papers, it was found that supplementation of microbial feed additive could gain better production performance of piglet, broiler and feedlot cattle, and prevent disease occurrence. It has been suggested that the benefieal actions of microbial feed additive include, normalizing the intestinal microbial flora, improving digestion and absorption of nutrients, producing non-specific immunomodulators and preventing the production of toxic substances. The suggestion and existing problems of studing and feeding microbial feed additive were also discussed in the paper.
