据文献报道，猪繁殖与呼吸综合征病毒（PRRSv）爆发造成的经济损失相当高，但尚无最新数据。本研究的目的是量化荷兰母猪群中流行性 PRRSv 爆发的经济影响。根据已确认的猪群内 PRRSv 爆发情况，选择了 9 个母猪群。通过使用不同因素（生产数据、药物、诊断、劳动力等）比较疫情爆发前和疫情后的总体成本，估算了疫情爆发后前 18 周的经济影响。蓝耳病病毒的爆发导致每头母猪的出售生猪数量减少了 1.7 头。每 18 周爆发期间，一头母猪的经济损失在 (原文如此)59 和 (原文如此)379 之间。每次爆发每头母猪的平均损失为（原文如此）126。由于农民应对 PRRSv 疫情的方法不同，疫情爆发后，每头母猪的成本从 (原文如此)3 到 (原文如此)160 不等。本研究中计算的成本与荷兰最初爆发时每头母猪的成本 (原文如此)98 相关。
The economic losses due to porcine reproductive and respiratory syndrome virus (PRRSv) outbreaks are reported in the literature to be substantially high, but recent figures are not available. The aim of this study was to quantify the economic effects of epidemic PRRSv outbreaks in Dutch sow herds. Nine sow herds were selected based on a confirmed PRRSv outbreak within those populations. The economic impact during the first 18 weeks after the outbreak was estimated by comparing the overall costs between pre- and postoutbreak periods, using different factors (production data, medication, diagnostics, labour, etc.). An outbreak of PRRSv resulted in a reduced number of sold pigs per sow of 1.7. The economic loss varied between (sic)59 and (sic)379 for one sow per 18-week period outbreak. The mean loss per sow per outbreak was (sic)126. The costs after the outbreak varied significantly from (sic)3 to (sic)160 per sow, due to the different methods used by farmers to tackle PRRSv outbreaks. The calculated costs in this study correlate with the costs of the initial outbreak in The Netherlands of (sic)98 per sow.
