The clinical protection provided by the combined administration of ERYSENG® PARVO and UNISTRAIN® PRRS against the Porcine Reproductive Respiratory Syndrome (PRRS) in gilts was assessed in this study. Reproductive performance after a heterologous challenge was the main efficacy parameter.

The combined administration of ERYSENG® PARVO and UNISTRAIN® PRRS significantly reduced the number of weak piglets and the presence of mummies in vaccinated gilts after a heterologous PRRSV challenge. So the use of the vaccine mixture clinically protected gilts from a heterologous PRRSV infection. The results obtained allow the conclusion to be drawn, that efficacy in terms of clinical protection after a PRRS challenge with the combined use of the two vaccines is comparable to that of UNISTRAIN® PRRS administered alone.
