【摘要】：饲用蛋白酶因其节约蛋白的作用而备受关注。本文就饲用蛋白酶的分类、酶学特性评价体系以及饲用蛋白酶的作用特征和应用作一综述,着重阐述了饲用蛋白酶的作用特征,即动物种属与年龄依赖性、原料依赖性、蛋白节约效应、与其他酶制剂的协同效应以及额外营养生理效应;具体阐述了在改良饲料原料品质、提高动物生产性能、节约饲料成本、减少N、P排放等方面的应用。饲用蛋白酶的应用要根据动物种属、年龄和生理阶段以及日粮和环境因素进行调整,尤其要利用好蛋白酶的协同效应与其他酶制剂进行复配,以及不同饲用阶段酶制剂的作用与延续性,本文为蛋白酶在饲料生产中更好的应用提供参考。
[Abstract]:Feed protease has attracted much attention because of its protein-saving effect. This article reviews the classification of feed protease, the evaluation system of enzyme characteristics, and the action characteristics and application of feed protease. The functional characteristics of feed protease, namely, species and age dependence, material dependence, protein saving effect, synergistic effect with other enzyme preparations and additional nutritional physiological effects, were emphasized. The application of feed protease in improving feed raw material quality, improving animal production performance, saving feed cost and reducing Nu P emission were described in detail. The application of feed protease should be based on the species of animals. Age, physiological stage, dietary and environmental factors should be adjusted, in particular, the synergistic effect of good protease should be combined with other enzyme preparations, as well as the effect and continuity of enzyme preparation in different feeding stages. This paper provides a reference for the better application of protease in feed production.
