Hysterectomy and early weaning (with onsite and offsite farrowing) were used in four endemically infected case herds to obtain piglets free from porcine reproductive and respiratory syndrome virus (PRRSV). Both conventional and one-step polymerase chain reaction (PCR) procedures were used to monitor the PRRSV status of the piglets.
