An outbreak of foot lameness in a dairy herd of 170 goats is described. The herd, that was kept mostly indoors, was attended between December 2006 and November 2007. During this period, 15% of the goats showed lameness with foot lesions and 24% of the goats showed lameness without foot lesions. The foot lesions consisted of cracks and erosions on the horn of the bulbs of the heel that in most cases extended along the internal side of the axial hoof wall. The clinical diagnosis was interdigital dermatitis. Annual milk production was lower in lame goats compared to those that were not lame (P<0.05). Furthermore, annual milk yield was significantly affected by the type of foot disease present and was significantly lower in cases with foot lesions than in the animals that were not lame (P<0.05) and also in the lame goats without foot lesions (P<0.05).
描述了一个拥有170只山羊的奶牛群中发生的蹄部跛行疫情。该牛群大多饲养在室内，在2006年12月至2007年11月期间接受观察。在此期间，15%的山羊出现伴有蹄部病变的跛行，24%的山羊出现无蹄部病变的跛行。蹄部病变包括足跟球部角质层的裂缝和糜烂，在大多数情况下，这些病变沿着轴蹄壁的内侧延伸。临床诊断为指间皮炎。与非跛行山羊相比，跛行山羊的年奶产量较低（P<0.05）。此外，年奶产量受现存蹄部疾病类型的显著影响，有蹄部病变的病例的年奶产量显著低于非跛行动物（P<0.05），也低于无蹄部病变的跛行山羊（P<0.05）。
