Porcine Epidemic Diarrhoea Virus: Welfare Impacts

PEDV causes devastating diarrhoea in pig herds, particularly affecting neonatal piglets. This guide covers welfare impacts and biosecurity.

Key Facts

PEDV is a coronavirus causing profuse watery diarrhoea in pigs of all ages
Neonatal piglets under 10 days old have near 100% mortality without intervention
Surviving pigs dehydrate rapidly requiring intensive supportive care
The virus spreads easily through contaminated vehicles, equipment, and people
Biosecurity is the primary defence — once on a farm, eradication is very difficult
Feedback vaccination (intentional controlled exposure of sows) provides some protection

Welfare Considerations and Management

PEDV welfare management requires intensive nursing of affected pigs alongside strict biosecurity to prevent spread. Fluid therapy for dehydrated pigs is the cornerstone of treatment. Neonatal piglets may need stomach tubing with electrolytes. Maintaining warmth is critical as diarrhoea causes rapid chilling. Biosecurity interventions including vehicle disinfection, boot dips, and visitor restrictions prevent introduction. Feedback vaccination with controlled sow exposure provides passive immunity to suckling piglets.

What You Can Do

Implement strict biosecurity protocols to prevent PEDV introduction
Have rehydration fluids and stomach tubes available for neonatal piglet support
Ensure warm, dry environments to prevent chilling of affected piglets
Report suspected PEDV to your vet immediately for rapid diagnosis and response
