Evaluating Aptimmune Vaccine in PRRS Viremic Pigs

Carrie Muehling

At the 2018 Aptimmune Scientific Symposium, Dr. Andy Kryzer of Fairmont Veterinary Clinic in Fairmont, Minn., shared an evaluation of the Aptimmune vaccine in Porcine Reproductive and Respiratory Syndrome (PRRS) viremic piglets.

Kryzer said the study trialed the vaccine at weaning only versus weaning and two weeks post weaning to see if the approaches were equally effective at reducing PRRS viremia and improving average daily gains through the nursery phase.

“Ultimately, the result is we saw fewer light weight pigs in the vaccinate groups versus the control, however we weren’t able to continue the trial through the finishing phase so ultimately would like to do that work to see how does this vaccine perform on the pigs through the finishing,” said Kryzer. “Does the difference that we see at the end of the nursery actually hit the first cut out of the barn?”

Kryzer noted that in this project there was a fairly low prevalence of PRRS – less than 20 percent of these pigs were positive.
