摘要: 我国果渣、饼粕、糟糠等非常规饲料资源十分丰富,但较高的非淀粉多糖含量影响了其在动物生产中的应用,其中高达20%的果胶成分不仅利用率低,而且影响其他营养物质的消化吸收,被视为单胃动物营养中的抗营养因子。近年来,关于非淀粉多糖中的纤维素、半纤维素的研究较多,但关于饲料中果胶生物降解方面的研究却鲜有报道。本文综述了饲料中果胶的结构、分布、营养特性及其微生物降解研究进展,以期为玉米、豆粕的减量化替代提供新的思路与方法。

Abstract: The unconventional feed resources such as pomace, oilseed meal and bran are abundant in China, but the high non-starch polysaccharides content affects their application in animal production. The pectin component, which is as high as 20%, is not only poorly utilized but also affects the digestion and absorption of other nutrients, and is regarded as an anti-nutritional factor in feed of monogastric animals. In recent years, there have been more studies on the cellulose and hemicellulose components of non-starch polysaccharides, but little research has been reported on the biodegradation of pectin in feeds. This paper reviewed the structure, distribution and nutritional properties of pectin in feed and the progress of its microbial degradation in order to provide a new idea and method for reduction and substitution of corn and soybean meal.

Key words: pectin, pectinase, microorganism, biodegradation
