A five year-old bull moose (Alces alces) was culled due to chronic hoof overgrowth that required frequent intervention. Radiographic examination revealed changes in phalangeal bone structure usually considered indicative for laminitis in domestic cattle; similar changes were absent in the hooves of a free-ranging moose of similar age. The captive animal had been maintained in exhibits whose flooring were much harder than the soil in natural moose habitat, and on a diet with a high proportion of easily fermentable carbohydrates. These findings indicate that chronic laminitis should be considered as a potential underlying factor for hoof overgrowth, and that measures aimed at reducing the incidence of laminitis in domestic cattle, such as the use of softer flooring and diets with a higher proportion of fibre, might have prophylactic potential in captive wild ruminants.
