Description: When footrot is endemic in a flock and lesions have been present in the hoof epithelium for months to years, a wide range of signs associated with disordered keratin production can occur. The most obvious sign is misshapen digits and overgrowth of hard horn of one or both digits of affected feet. Inflammation of interdigital skin and underrunning may not be obvious unless pasture conditions are conducive to expression of active footrot lesions.

Figure 2. Chronic lesion. The outcome of severe chronic footrot in a weaner lamb. Inflammation of the interdigital skin has subsided and underrunning of the horn is no longer obvious. The sheep has been maintained on soft ground, which has contributed to misshapen and overgrown hooves. Photo: Om Dhungyel
