'Kangaroo gait' in ewes: a peripheral neuropathy.

The clinical and pathological features of two lactating ewes with 'kangaroo gait', a locomotory disorder, are described, along with brief details of two further archival cases. Clinical neuropathological signs were consistent with a bilateral radial paresis and pathologically there was a polyneuropathy with preferential severe involvement of radial nerves. Flock incidence of the condition is low and previous experience suggests the clinical disorder is not progressive, recovery occurring at the end of lactation. The cause is unknown.
