| Abstract: | PEDV,TGEV and PoRV are the main pathogenies of porcine viral diarrhea that endanger the healthy development of swine industry,which are characterized by vomiting,severe diarrhea and dehydration, the morbidity and mortality of suckling piglets is higher,and the incidence of diarrhea is lower in replacement gilts,sows or fattening pigs. Especially since 2010, the prevalence of PEDV mutant strains has had a serious impact on the global swine industry,but the control measures can not been able to cope with the new epidemic situation. In recent years, many new techniques or methods have been applied to the control of swine viral diarrhea caused by PEDV, TGEV and PoRV. Based on the analysis of genetic variation and epidemic status of three kinds of viruses,this paper reviewed the prevention and control measures from the aspects of feeding management,immunization prevention, traditional Chinese medicine therapy,interference therapy,specific therapy and return therapy. |
