In 1999, a study was initiated to improve the treatment and control of footrot and interdigital dermatitis in sheep flocks in England and Wales. In November 2000, a retrospective cross-sectional study was conducted in which 392 sheep farmers were asked to estimate the prevalence of footrot and interdigital dermatitis in their flock in the previous 12 months, whether they considered these diseases to be a problem, how they treated and controlled them and their opinion on the success of the treatment and control measures that they used; 209 of them provided usable responses. The farmers tended to be more concerned as the prevalence of the diseases increased; 91 per cent of the farmers with a prevalence of footrot of less than 5 per cent considered it a small or very small problem on their farm, but 51 per cent of the farmers with a prevalence of 5 per cent or more also considered it to be a small or very small problem. Approximately 60 per cent of the farmers who used parenteral antibiotics considered that they were good or excellent at treating footrot, and this treatment was associated with a prevalence of less than 5 per cent. A similar proportion of farmers also considered topical foot sprays and footbathing to be good or excellent for controlling footrot or interdigital dermatitis, but these treatments were not associated with a lower prevalence of footrot or interdigital dermatitis. Of the 29 farmers who used a footrot vaccine, 20 (69 per cent) considered it good to excellent and this was associated with a prevalence of footrot of less than 5 per cent in their flock; however, vaccination was not associated with lower levels of footrot across the whole sample. Farmers spent approximately 34 minutes per sheep per year treating and controlling footrot; 31 per cent were prepared to spend more money and more time to manage footrot, 27 per cent were prepared to spend more time, 19 per cent were prepared to spend more money and 23 per cent were not prepared to do either. The farmers who were willing to invest more money or more money and time had a higher prevalence of footrot.
1999年，一项旨在改善英格兰和威尔士羊群腐蹄病及趾间皮炎治疗与防控情况的研究启动。2000年11月，开展了一项回顾性横断面研究，研究要求392位养羊户估算其羊群在过去12个月里腐蹄病及趾间皮炎的患病率，他们是否认为这些疾病是个问题，他们如何治疗和控制这些疾病以及他们对所采用的治疗和控制措施的成效的看法；其中209位养羊户给出了有效回复。随着疾病患病率的上升，养殖户往往更加担忧；腐蹄病患病率低于5%的养殖户中，91%认为这在他们农场是个小问题或非常小的问题，但患病率为5%或更高的养殖户中，也有51%认为这是个小问题或非常小的问题。约60%使用注射用抗生素的养殖户认为这些抗生素治疗腐蹄病效果良好或极佳，采用这种治疗方法时，患病率低于5%。类似比例的养殖户也认为局部喷蹄剂和蹄浴对于控制腐蹄病或趾间皮炎效果良好或极佳，但这些治疗方法与腐蹄病或趾间皮炎患病率降低并无关联。在使用腐蹄病疫苗的29位养殖户中，20位（69%）认为其效果良好至极佳，且这与他们羊群中低于5%的腐蹄病患病率相关；然而，在整个样本中，接种疫苗与较低的腐蹄病发病率并无关联。养殖户每年为每只羊治疗和控制腐蹄病大约花费34分钟；31%的养殖户准备投入更多资金和时间来应对腐蹄病，27%的养殖户准备投入更多时间，19%的养殖户准备投入更多资金，23%的养殖户两者都不准备投入。愿意投入更多资金或更多资金和时间的养殖户，其羊群中腐蹄病的患病率更高。
