Porcine Reproductive and Respiratory Syndrome (PRRS) is the most economically significant pig disease globally, and growing evidence shows that enrichment provision may influence disease susceptibility and resilience.
The intersection of PRRS management and environmental enrichment is an emerging area of research with significant practical implications. If enrichment provision demonstrably reduces PRRS susceptibility or severity through stress pathway modulation, the economic case for enrichment becomes compelling to even purely commercially motivated producers. Current evidence is suggestive rather than definitive, but the biological mechanisms linking chronic stress to immunosuppression are well established. Integrating enrichment provision into PRRS biosecurity and management protocols - framing it as a welfare and disease management tool simultaneously - may be an effective strategy for increasing uptake in commercial systems.
