本研究的目的是评估农民识别和报告跛行的准确性，在他们的羊群相比，研究人员观察到的跛行的患病率。参观了35个养羊场。农民被要求估计2008年跛行的流行率，在羊群和一组羊，研究人员在同一天检查。然后将这些估计值与研究人员对跛行的估计值进行比较。所有的农民都能够识别跛脚羊，但与研究人员的估计相比，他们在选择进行检查的组中报告的跛脚患病率略低。低估的比例随着该组跛行患病率的增加而增加。农民对这一天的估计与研究人员对跛行患病率的估计一致、密切和显著相关。我们的结论是，农民估计患病率的羊跛行是一个足够准确和可靠的工具，风险因素的研究。在全国范围内，绵羊跛行的患病率可能比目前估计的10%高出2- 3%。
The aim of this study was to assess the accuracy of farmer recognition and reporting of lameness in their sheep flock when compared with the prevalence of lameness observed by a researcher. Thirty-five sheep farms were visited. Farmers were asked for estimates of the prevalence of lameness in 2008, in the flock and in one group of sheep that was inspected by the researcher the same day. These estimates were then compared with the researcher's estimate of lameness. All farmers were able to recognise lame sheep but they slightly under reported the prevalence of lameness in the group selected for examination when compared with the researcher's estimate. The proportion underestimated increased as the prevalence of lameness in the group increased. Farmer estimates on the day were consistently, closely and significantly correlated to that of the researcher's estimate of prevalence of lameness. We conclude that farmer estimates of prevalence of lameness in sheep are a sufficiently accurate and reliable tool for risk factor studies. The prevalence of lameness in sheep, nationally, is probably higher than the current estimate of 10% by 2-3%.
