The aim of this study was to establish, for the first time, a systematic monitoring system for PRRS in Spanish sow farms to classify farms according the PRRS status using terminology currently adopted in the US swine industry. Furthermore, we investigated associations between PRRS status of PRRS-positive breeding herds, and selected production parameters, allowing the characterization, for the first time, of production and economic impact of PRRSV under Spanish field conditions.
