You should really do them before farrowing as this would have given the piglets immunity too but do as HH suggests. We use Ery-P.
Amounts to be administered and administration route
The dose is 2 ml per pig, given by deep intramuscular injection behind the ear.
Allow vaccine to reach room temperature (15° - 25°C) before use.
Vaccination programme
Gilts should be vaccinated against
E. rhusiopathiae and porcine parvo virus (PPV) before first mating. A single injection, not less than 2 weeks before mating is sufficient to protect the following pregnancy from damage due to PPV. For the induction of protection against erysipelas, an initial course of two vaccinations is recommended. This can be achieved with the single component erysipelas vaccine given either 4 weeks before, or 4 weeks after the administration of Porcilis Ery+Parvo.
Sows should be revaccinated against erysipelas during each lactation period (i.e. at no more than 6 month intervals) and against parvovirus annually.
