Lessons Learned from POMP – PRRSV Outbreak Management Program

June 15, 2022 — 

Porcine reproductive and respiratory syndrome continues to be one of the most important pathogens in the global swine industry. Findings from a recent cohort study, the PRRS Outbreak and Management Practices have shown that there is a large diversity of management practices across the U.S swine industry to deal with PRRS outbreaks in breeding herds. The findings and deliverables of POMP included a benchmarking platform to collect and analyze PRRS outbreak data. Results revealed a large diversity of management and immunological solution approaches implemented in breeding herds either to control or eliminate PRRSV.

The inconsistency in the implementation of standardized protocols and genetic evolution of PRRSV strains have shown an increase in time in weeks to achieve time-to-low-prevalence, time-to-baseline-productivity and total losses, when compared with a study conducted 10 years ago (Linhares et al., 2014). Table 1 shows the difference between the previous cohort and the POMP 2019-2021 cohort. The median time to low prevalence was nine weeks and the time to baseline production was six weeks longer, and the total losses increased by 1,303 piglets per 1,000 sows, respectively, compared with the 2011 study.
