摘要
木聚糖酶是一组能够将木聚糖中β-1,4-D-木糖苷键水解并生成低聚木糖或木糖的水解酶。研究表明,木聚糖酶可通过消除细胞壁"笼蔽效应"、降低食糜黏度、减少内源损失以及改善肠道菌群结构来改善畜禽的生产性能及养分和能量利用率。文章主要对木聚糖酶在畜禽饲料中的应用效果及其作用机制相关研究进行综述。
Xylanases are hydrolytic enzymes which can cleave β-1, 4-D-xylosidic linkages in xylan, leading to the formation of xylo-oligosaccharides and free xylose. Previous studies documented that xylanase could improve animals＇ growth performance and nutrient and energy digestibility by reducing the cage effect of cell wall, digesta viscosity and endogenous losses and improving intestinal microflora. This paper mainly reviews the application effects and mechanisms of action of xylanase in animal feed.
