I want to make sure that all breeding stock joining the herd will not suffer PRRS disease. Can I vaccinate them and at what age should I do it?
Ideally, gilts should be vaccinated before they join the breeding herd. Porcilis PRRS can be given from 2 weeks of age. There should be at least 4 weeks between vaccination and joining the herd. However gilts coming from a PRRSV negative farm should not be vaccinated at the farm of origin. Vaccination in a quarantine facility before entering the breeding farm would be a good option.
