Archive Case #22: Ovine Foot Rot

Clinical Clues

1. A ewe is presented for lameness affecting one hindlimb.
2. The farmer reports the problem has become more common after prolonged wet weather.
3. The hoof is malodorous and the interdigital skin is inflamed.
4. Separation of the horn from underlying tissue is visible on closer examination.
5. Several flock mates are beginning to show similar signs.
6. A contagious bacterial disease of the ovine foot causes underrunning hoof horn and foul-smelling lameness.

Diagnosis

Ovine Foot Rot

This case is most consistent with Ovine Foot Rot because the ewe has foul-smelling lameness, inflamed interdigital tissue, and underrunning hoof horn in wet conditions. The most important clues are the characteristic hoof lesions and flock spread, which make simple foot scald less likely.
