Pathogenic Mechanisms and Advances in Nutritional Regulation in Porcine Enteric Virus Infections
Diarrhea is a global challenge in the pig farming industry,especially when it comes to piglet diarrhe-a caused by porcine enteric viruses.The relationship between nutrition and animal health is extremely close,and nutritional intervention has become a crucial measure in preventing and controlling enteric virus infections.The theoretical foundation of nutritional intervention lies in understanding the pathogenic mechanisms of the vi-rus and the regulatory role of nutrition in the virus,its infection,and the animal recovery process.This article,while briefly describing the main characteristics of porcine enteric viruses,focuses on summarizing research progress in the pathogenic mechanisms of the virus and the regulatory effects of nutrition on aspects such as im-mune,cell fate and intestinal microbiota.The aim is to provide a reference for a deeper understanding and re-search on the relationship between nutrition and porcine enteric viruses,and to develop nutritional technologies for intestinal health and disease resistance.[Chinese Journal of Animal Nutrition,2024,36(4):2041-2056]
