Could something as seemingly simple as air quality management cut your PRRS outbreak risk in half? The latest research suggests exactly that – and it's changing how producers think about biosecurity investments.
A groundbreaking study from the University of Minnesota has revealed that properly implemented air filtration systems reduce PRRS outbreak risks by 51-58% compared to non-filtered farms. This comprehensive research analyzed data from the Morrison Swine Health Monitoring Project, representing about 60% of US breeding herds over a 15+ year period. What makes this study particularly valuable is its consideration of both positive and negative pressure filtration systems, along wi...
