Efficient Isolation, Expression and Improvement Technique System for Feed Enzymes in China

Supplementation of hydrolytic enzymes in feed can decrease the effect of anti‐nutritional factors and increase feed conversion rate by 5‐10%. Consequently, this practice can improve the efficiency of livestock production and reduce environmental contamination. The authors have developed a highly efficient platform to enrich the genetic resources of several enzymes, characterize and assess their application potentials, and achieve high‐yield production. These works make the production of novel enzymes cost‐effective and commercially valuable.
