Lesions of the sole, ranging in severity from discolouration to ulceration of the sole and undermining of the horn of the wall and sole, are common in heifers under the conditions prevailing in the Netherlands. In view of the similarity of these lesions in the two lateral claws of the hind-feet of the same animal, both as regards the localization on the sole and the severity of the lesions as well as the time of onset, these lesions cannot be solely attributed to mechanical injury. Also in view of the fact that they are associated with the time of calving, they may be regarded as symptoms of chromic laminitis. Housing (loose housing versus trying stalls) and the season of calving (housing period versus grazing period) are factors in the incidence of lesions of the sole.
在荷兰普遍存在的条件下，母牛的蹄底病变很常见，严重程度从蹄底变色到溃疡，以及蹄壁和蹄底角质层被侵蚀不等。鉴于同一动物后蹄两只侧爪上这些病变的相似性，无论是在蹄底的定位、病变的严重程度还是发病时间方面，这些病变不能仅仅归因于机械损伤。此外，鉴于它们与产犊时间相关，它们可能被视为慢性蹄叶炎的症状。饲养方式（散养与栓养）和产犊季节（舍饲期与放牧期）是蹄底病变发生率的影响因素。
