Pig Trial Summary
In a commercial study, Prevacent PRRS-vaccinated pigs showed no reduction in growth performance or difference in body weight at day 50 or day 125.6
Prevacent did not shed through the air during the 28-day sampling period.

In pigs, Prevacent caused less viremia than an MLV competitor on days 14 to 35 post-vaccination.7

Whole Herd PRRS Control
- PRRS increases mortality and reduces growth performance of wean-to-finish pigs. PRRS may also cause an increase in the number of premature farrowings, late term abortions, stillborn piglets and mummified fetuses.9
- With no reduction in growth performance or an impact on farrowing as a result of vaccination, Prevacent is a safe and effective solution for PRRS control across production segments.3,8
