本研究的目的是估计和比较施马伦贝格病毒（SBV）的经济影响，在不同的绵羊生产持有部分预算和毛利率分析结合生产模型。考虑的绵羊生产类型是英国的低地春季产羔、高地春季产羔和早期产羔群，法国中部和西部的草羔羊群，法国的大规模产羔群和奶绵羊群。两种疾病的情况下，不同的输入参数与生殖问题进行了审议：低和高的影响。对最不确定的输入参数进行了敏感性分析，并使用所有最低和最高值运行模型，以估计疾病影响的范围。英国每年和母羊的估计SBV疾病净成本为19.65- 20.85英镑（高影响情景）和6.40- 6.58英镑（低影响情景）。不同生产类型之间未观察到重大差异。在法国，高影响情景下，肉羊饲养每年和母羊的SBV疾病净成本为15.59- 17.20英镑，低影响情景下为4.75- 5.26英镑。对于奶牛，高影响情景下每年和母羊的成本为29.81英镑，低影响情景下为10.34英镑。该模型是一个有用的决策支持工具，农民和兽医谁面临的决定，疾病控制措施。它们允许估计疾病对农场的影响，说明不同的生产做法，这为干预战略的成本效益分析创造了必要的基础，如疫苗接种。
The present study aimed to estimate and compare the economic impact of Schmallenberg virus (SBV) in different sheep production holdings using partial budget and gross margin analyses in combination with production models. The sheep production types considered were lowland spring lambing, upland spring lambing and early lambing flocks in the UK, and grass lamb flocks of the Centre and West of France, extensive lambing flocks and dairy sheep flocks in France. Two disease scenarios with distinct input parameters associated with reproductive problems were considered: low and high impact. Sensitivity analyses were performed for the most uncertain input parameters, and the models were run with all of the lowest and highest values to estimate the range of disease impact. The estimated net SBV disease cost per year and ewe for the UK was £19.65–£20.85 for the high impact scenario and £6.40–£6.58 for the low impact scenario. No major differences were observed between the different production types. For France, the net SBV disease cost per year and ewe for the meat sheep holdings was £15.59–£17.20 for the high impact scenario and £4.75–£5.26 for the low impact scenario. For the dairy sheep, the costs per year and ewe were £29.81 for the high impact scenario and £10.34 for the low impact scenario. The models represent a useful decision support tool for farmers and veterinarians who are facing decisions regarding disease control measures. They allow estimating disease impact on a farm accounting for differing production practices, which creates the necessary basis for cost effectiveness analysis of intervention strategies, such as vaccination.
