半纤维素酶在畜禽饲料中的应用及研究进展

摘要

半纤维素主要由木聚糖和甘露聚糖组成，是饲料中的关键抗营养因子，可阻碍营养成分消化，降低动物生长性能。半纤维素酶为复合酶系，主要包括木聚糖酶和甘露聚糖酶，其功能是降解半纤维素，消除抗营养性。主要介绍了饲用半纤维素酶中的木聚糖酶和甘露聚糖酶，并对其来源及在饲料工业中的应用进行了综述。%Hemicelluloses which mainly consist of xylan and mannan are key anti-nutritional factors in animal feed and cause decrease of animal growth performance and digestibility. Hemicellulases including xylanase and mannanase are multienzyme systems and can degrade hemicelluloses and eliminate their anti-nutritional effect in animal feed. This paper introduced the origin and application status of hemicellulases in feed industry with emphasis on xylanase and mannanase.
