This paper gives the first estimate of the prevalence and distribution of foot lesions in finishing pigs in the south-west of England for 33 years. It was based on the examination of 4038 finishing pigs from 21 units. There were 3727 out of 3974 (93.8 per cent) pigs with at least one foot lesion. The prevalence of different lesions was: toe erosion (33.0 per cent), sole erosion (62.1 per cent), heel erosion (13.0 per cent), heel flaps (14.4 per cent), white line lesions (55.4 per cent), false sand cracks (23.9 per cent) and wall separation (11.5 per cent). The hind feet were more commonly affected than the front feet, and on each foot the lateral digits were significantly more frequently affected than the medial digits. Sole erosions, heel flaps, wall separation and false sand cracks were more frequently observed on the lateral than the medial digit. Digits with sole erosions were significantly more likely to have heel flaps, white line lesions or false sand cracks than those without sole erosions. Furthermore, there was a within digit association between overgrown hooves and toe erosion. The effects of weightbearing, gait and environment on the development of foot lesions is discussed.
本文首次对英格兰西南部育肥猪足部病变的患病率及分布情况进行了33年来的评估。该评估基于对来自21个猪场的4038头育肥猪的检查。在3974头猪中，有3727头（93.8%）至少有一处足部病变。不同病变的患病率分别为：趾部糜烂（33.0%）、蹄底糜烂（62.1%）、蹄跟糜烂（13.0%）、蹄跟皮瓣（14.4%）、白线病变（55.4%）、假性砂裂（23.9%）和蹄壁分离（11.5%）。后蹄比前蹄更易受影响，且每只蹄的外侧趾比内侧趾受影响的频率显著更高。蹄底糜烂、蹄跟皮瓣、蹄壁分离和假性砂裂在外侧趾比在内侧趾更常被观察到。有蹄底糜烂的趾比没有蹄底糜烂的趾更有可能出现蹄跟皮瓣、白线病变或假性砂裂。此外，蹄过度生长与趾部糜烂在同一趾内存在关联。文中还讨论了负重、步态和环境对足部病变发展的影响。
