菌酶协同发酵菜籽粕在动物生产中的应用及存在问题

通过菌酶协同发酵技术提升菜籽粕类饲料质量和营养价值,改善适口性,降低饲料中植酸和硫苷含量,增加菜籽粕类饲料替换常规蛋白原料豆粕的比例,可在一定程度上缓解养殖业中大豆粕等蛋白饲料原料成本不断提高的问题。分析发酵菜籽粕处理常用方法——微生物发酵法和酶解法的优缺点,介绍制备菌酶协同发酵菜籽粕类饲料所需的菌种和酶制剂种类,综述菌酶协同发酵菜籽粕的功效,阐述其在动物生产中的应用现状及存在的问题,以期为菌酶协同发酵菜籽粕在畜禽生产中的科学应用提供参考。

Application of Fermented Rapeseed Meal by Bacteria Coupled with Enzymes in Animal Production and Existing Problems

Improving the quality, nutritional value, palatability and lowering the contents of phytic acid and thioglycoside of rapeseed meal feed through fermentation by bacteria coupled with enzymes, as well as increasing the proportion of rapeseed meal feed replacing conventional protein feedstuff help to alleviate the problem of rising costs of protein feed materials such as soybean meal in animal husbandry. In this paper, the benefits and drawbacks of the commonly used methods （microbial fermentation and enzymatic digestion） for preparing fermented rapeseed meal were analyzed, and the types of bacteria and enzymatic preparations used in fermentation of rapeseed meal feed by bacteria coupled with enzymes were introduced. In addition, the feeding value of fermented rapeseed meal by bacteria coupled with enzymes was reviewed, and its application status in animal production and existing problems were described, in hoping to provide a reference for the scientific application of fermented rapeseed meal by bacteria coupled with enzymes in livestock and poultry production.
