Efficacy of Porcilis PRRS - Protection versus reproductive signs

A trial to show how vaccination can reduce transplacental virus transmission and increase the numbers of pigs born alive per litter.

Trial

Two groups of PRRS-naïve gilts were used in this trial:

• Group 1: Vaccinated with Porcilis PRRS 2 weeks before mating
• Group 2: Unvaccinated controls

Both groups were challenged with a field PRRSV at 88 days of gestation.

Results

Results are show in the graphs below.

Conclusion

Vaccination with Porcilis PRRS reduced transplacental virus transmission and increased the numbers of pigs born alive per litter
