发酵棉籽蛋白的研究进展及在动物生产中的应用

Research progress of fermented cottonseed protein and its application in animal production

棉籽蛋白是一种优质蛋白质饲料,蛋白含量可达40%以上,但其中含有有害物质游离棉酚和多种抗营养因子,无法大量添加于动物饲料中。通过微生物发酵技术可有效地降低棉酚含量,还可提高发酵底物中益生菌、小分子肽、氨基酸等多种营养物质的含量,达到改善饲料品质和营养价值的作用。近年来,发酵棉籽蛋白部分代替豆粕在动物生产中的应用较为广泛,文章综述了发酵棉籽蛋白的研究进展及在动物生产中的应用,为相关生产应用及研究提供参考。

Cottonseed protein is a high-quality protein feed with a protein content of more than 40%,but it contains toxic substances free gossypol and various anti-nutritional factors,which cannot be added to animal feed in large quantities.Studies have shown that through microbial fermentation technology,it can effectively reduce the content of gossypol,and can also increase the content of probiotics,small molecular peptides,amino acids and other nutrients in the fermentation substrate,so as to improve the quality and nutritional value of feed.In recent years,fermented cottonseed protein has been widely used to partially replace soybean meal in animal production.The paper reviews the research progress of fermented cottonseed protein and its application in animal production.
