This article discusses two strategies used in field trials to control the spread of porcine reproductive and respiratory syndrome (PRRS) virus in a breeding herd. In the first experiment, two breeding herds were closed to outside replacements and replacement males and females were raised on the farms. In the second experiment, replacement gilts were held in an off-site holding facility and the nursery was depopulated. None of the experimental farms showed evidence of PRRS spread by IFA serology for the 6 months of the experiment.
