Porcine Reproductive and Respiratory Syndrome (PRRS) causes severe disease and welfare impacts in affected herds. Prevention and control protect pig welfare significantly.
Pigs affected by PRRS experience direct respiratory disease, immune suppression predisposing to multiple secondary infections, and in sows, reproductive failure. The disease causes significant cumulative welfare harm in affected herds. Biosecurity that prevents introduction and vaccination that reduces severity protect pig welfare from one of the most welfare-impacting diseases in the industry.
