[Laminitis with a high degree of osteitis rarefaciens of the distal phalanx in a Fleckvieh bull].

Chronic laminitis with severe rarefactive osteitis was diagnosed in a nine month old Simmental fattening bull. The condition was observed in all eight weight bearing digits. Clinical, radiological and pathomorphological examinations revealed osteolysis and downward rotation of all the distal phalanges. The condition appears to resemble the several cases of laminitis in Jersey cattle, which have been attributed to hereditary factors. In this case, however, the genetic background was unavailable for evaluation.
