摘要
纳豆芽孢杆菌是一种需氧型益生菌，属于枯草芽孢杆菌的一个亚种，具有良好的耐胃酸、耐饲料制粒高温和耐储存性能，进入动物肠道后能够迅速萌发并消耗肠道内的游离氧营造厌氧环境，代谢产生多种消化酶、纳豆激酶和抑菌物质。在动物饲料中添加纳豆芽孢杆菌。可以调节动物肠道功能紊乱。维持肠道菌群平衡，提高机体免疫力，降低肠炎和腹泻发生率，促进动物生长，提高饲料利用率，改善动物生产性能，是一种应用价值较高的微生物饲料添加剂。
Bacillus natto is an aerobic probiotic for one subspecies of Bacillus subtilis, which has good acid resistance, high temperature resistance in feed pelleting process and storage stablili- ty. It can germinate quickly and consume the free oxygen in the intestine to create an anaerobic environment after entering the intestines of animals, metabolizing a variety of digestive enzymes, nattokinase and bacteriostat.Addition of Bacillus natto in feed can regulate animal intestinal dysfunction, maintain the balance of intestinal flora, improve the immunity, reduce the incidence of enteritis and diarrhea, promote animal growth, increase feed conversion rate, improve animal pro- duction performance.Thus, Bacillus natto is a highly valuable microbial feed additive.
