Ireland’s largest producer of pig semen is investigating how porcine reproductive and respiratory syndrome virus  (PRRSV) infected its boars, where the air entering the facility is filtered. As a precaution, p ig semen is now being imported from Britain.  

Hermitage Genetics in Kilkenny, confirmed that three of its boars were found to have PRRSV. The disease was detected in the pigs at its quarantined artificial insemination station in Callan following testing. It is the first time blue ear has been found in the Hermitage’s pigs.  Some commercial pig farms are implicated too.
