发酵豆粕技术及其在单胃动物和水产动物上应用的研究进展

Soybean meal fermentation technology and its application in monogastric animals and aquaculture

豆粕是一种重要的饲料原料,但因其含有胰蛋白酶抑制因子、大豆抗原蛋白、寡糖等营养抑制因子,从而限制了豆粕的应用。通过微生物发酵技术可以缓解这一问题。细菌和真菌均可通过发酵降低豆粕中的抗营养因子,提高小肽含量,改善必需氨基酸和非必需氨基酸的含量。发酵豆粕品质与添加的菌株种类密切相关,菌株种类不同,则发酵豆粕营养成分含量也有所差异。饲喂发酵豆粕可以提高单胃动物的日增重,改善生产性能,对提高蛋白利用率等具有明显的改善作用;可降低水产动物的饲料成本。发酵豆粕在未来的动物生产上具有较好的应用前景。

Soybean meal is an important protein source for animal feed, but it contains many kinds of anti-nutritional factors, such as trypsin inhibitor, soybean antigen, staehyose and so on, which limits its application. Fermentation using microorganism could alleviate this problem. Bacteria and fungi re- sult the concentration of anti-nutritional factors, improve the concentration of peptides and amino ac- ids by fermentation. The fermentation quality varies from difterent strains. Fermented soybean meal eouhl improve the performance and product quality of monogastric animals, reduce the feed cost in aquaculture. In future, fermented soybean meal would be used widely in animal breeding.
