蛋白酶在饲料工程中的应用进展
Advances in Application of Proteases in Feed Engineering
摘要
Abstract
Feed engineering is a critical technological field ensuring the efficiency and sustainable develop-ment of livestock,poultry,and aquaculture industries.In recent years,against the backdrop of frequent fluc-tuations in protein raw material prices,the phase-out of antibiotics,and increasing demands for green farm-ing,higher requirements have been placed on the application of functional feed additives.Within this con-text,proteases,as important feed enzyme preparations,significantly improve feed quality and breeding effi-ciency through mechanisms such as compensating for insufficient endogenous enzyme secretion in animals,degrading antinutritional factors in feed,and enhancing the digestibility and utilization of protein and amino acids.Currently,protease enzyme preparations account for 60%of the total global enzyme market value,demonstrating broad application prospects.The article systematically reviews the classification and bio-chemical characteristics of feed proteases,with a focus on four main application areas in feed engineering:improving the digestibility and utilization of protein and amino acids;enhancing the application value of unconventional protein raw materials;reducing nitrogen emissions to achieve environmentally friendly farm-ing;and regulating intestinal health to enhance disease resistance in animals.Furthermore,the article dis-cusses the reasons for differences in protease application effects based on key factors such as animal species and growth stages,feed ingredient composition,and enzyme properties.Using the example of high-protein corn enzymatic hydroly-sis,targeted application strategies are proposed,providing theoretical and practical references for promoting the precision and large-scale application of pro-teases in feed engineering.关键词
