In terms of the application of plant extracts, it co-established an engineering technology center for the development and utilization of plant extracts with the Animal Nutrition Institute of Sichuan Agricultural University, which revealed the nutritional regulation rules and mechanisms of animal health on the basis of many years of profound research in the field of nutrition and health. Currently, it is committed to analyzing the active ingredients in plant extraction monomers and formulations and their efficacy development and verification, and innovatively proposes the application of natural plant active ingredients in animal production to replace traditional feeding antibiotics, improve animal health, ensure the safety of animal products, and establish a reference database of functional ingredients in plant extraction raw materials. In addition, through the construction of in vivo and in vitro stress and pathological models, the mitigation effect of plant active ingredients on stress and disease was discussed, and the potential value of plant extracts in animal anti-stress and disease was played to ensure animal health, reduce disease, reduce drug use, and achieve safe and efficient production of animal products.
