How to do pig epidemic diarrhea?
1. Strengthen feeding and management:
Pay attention to the disinfection of the enclosure and the heat preservation of the delivery room. Once there are sick pigs in the enclosure, they should be isolated or eliminated immediately. In the pig farm where the disease is occurring, the virus content can be reduced by intramuscular injection of interferon in pregnant sows and continuous intramuscular injection of interferon in postnatal piglets to establish a passive protective barrier. Strengthening the biosafety of pig farms, improving the immune efficacy of existing vaccines and raising the maternal antibody level of sows are the top priorities for the prevention and control of porcine epidemic diarrhea. Inappropriate, excessive and frequent re-feeding can not control the epidemic disease, but will only cause the disease to occur repeatedly in the field, so we must carefully consider re-feeding.
2. Strengthen vaccine prevention.
The epidemic of epidemic diarrhea can be effectively prevented and controlled by reasonably adjusting the immunization procedure with the existing vaccine, appropriately increasing the immunization times and dose, and strengthening the comprehensive management. It is worth pointing out that the classical vaccine strain has a certain cross-protective effect on the epidemic strain. Even if epidemic diarrhea occurs in the epidemic prevention pig farm, the severity of the disease and the loss will be greatly reduced, while in the unimmunized pig farm, once the epidemic diarrhea outbreak occurs, it will cause very serious economic losses.
