European PRRSpective 2023 session 1 Improving health in endemic infected Sow farm
Gilts should be in a biosecure facility (i.e., quarantine), avoiding unexpected infections before introduction to sow farms, to avoid the disease outbreaks in sows and offspring. Relying solely on natural immunization does not result in even (homogeneous) and consistent immunity. If the gilts are housed in a continuous flow system before entering the sow herd, they can carry PRRS virus from recently placed animals to the sow breeding unit.
