在2005年，3000份问卷被发送到一个随机样本的英国牧羊人从英国牛肉和羊肉执行（EBLEX）保存的名单，调查农民是否可以正确地命名六个常见的足部病变的羊从一个特征图片和书面描述。这些病变包括趾间皮炎（ID）、蹄癣（FR）、接触传染性绵羊趾皮炎（CODD）、剥蹄、足脓肿和趾肉芽肿。此外，农民被要求报告2004年他们羊群中跛脚羊的总百分比，以及上述六种病变中每一种所占的跛脚百分比。总体回答率为44%，可用回答率为32%。262名回答所有6个问题的农民中有59名（23%）正确命名了所有6种病变。这比预期的偶然性要大。在专家绵羊顾问（主要是兽医）的会议上提出了六种病变的相同问卷，37/47（79%）的应答者正确地命名了所有六种病变。从上面列出的六种病变中，农民正确命名的百分比约为83%，85%，36%，28%，65%和43%，错误归因于另一种病变的百分比为5%，47%、10%、13%、35%和7%。最常用的错误名称是FR，农民倾向于将任何蹄角病变命名为FR。将正确命名的病变与错误命名为FR的相同病变的羊跛足分布进行比较，表明农民认识到病变，但没有正确命名它们;跛行的分布符合正确命名的病变的模式，而不是归因于FR的跛行模式。所有跛行的平均患病率为10.4%，其中ID、FR、CODD、剥蹄、足脓肿和脚趾肉芽肿的患病率分别为6.9%、3.7%、2.4%、1.9%、0.9%和0.8%。虽然ID和FR是大多数鸡群中最常见的跛行原因，但在高达17%的鸡群中，跛行的主要原因可能是不同的病变。(C)2007 Elsevier B.

In 2005, 3000 questionnaires were sent to a random sample of English sheep farmers from a list kept by the English Beef and Lamb Executive (EBLEX) to investigate whether farmers could correctly name six common foot lesions in sheep from a characteristic picture and a written description. The lesions were interdigital dermatitis (ID), footrot (FR), contagious ovine digital dermatitis (CODD), shelly hoof, foot abscess and toe granuloma. In addition, farmers were asked to report the total percent of lame sheep in their flock in 2004 and the percent of this lameness attributable to each of the six lesions listed above. The overall response percentage was 44 with a useable response of 32%.Fifty-nine farmers out of 262 (23%) who answered all six questions named all six lesions correctly. This was greater than expected by chance. The same questionnaire of six lesions was presented at a meeting of specialist sheep advisors, primarily veterinarians, 37/47 (79%) responders named all six lesions correctly.From the six lesions listed above, the percent correctly named by farmers was approximately 83%, 85%, 36%, 28%, 65% and 43% and the percent incorrectly attributed to another lesion was 5%, 47%, 10%, 13%, 35% and 7%, respectively. The most commonly used incorrect name was FR, with farmers tending to name any hoof horn lesion as FR. A comparison of the distribution of sheep lame by a lesion correctly named compared with the same lesion incorrectly named as FR suggested that farmers recognised lesions but did not name them correctly; the distribution of lameness fitted the pattern for the correctly named lesion rather than the pattern of lameness attributed to FR. The results were validated with farm visits and a repeatability study of the questionnaire.The mean farm er-estimated prevalence for all lameness was 10.4%; with 6.9%, 3.7%, 2.4%, 1.9%, 0.9% and 0.8% of the sheep lame with ID, FR, CODD, shelly hoof, foot abscess and toe granuloma respectively from respondents who correctly named these lesions. Whilst ID and FR were the most prevalent causes of lameness in most flocks it is possible that in up to 17% flocks the primary cause of lameness was a different lesion. (C) 2007 Elsevier B.V.
