Bradycardia, altered thermographic patterns, and dysphonia associated with cervical laxity in an Ankole-Watusi bull.
A native African bull was examined for ataxia of 10 days' duration. Clinical signs included bradycardia, ataxia, hypermetria, and dysphonia. Cerebrospinal creatine kinase activity was high. Thermographic evidence of bilateral accessory nerve dysfunction was observed. This finding was supported by electromyographic studies. Survey and positive contrast radiographs were nondiagnostic. Clinical signs exacerbated after radiographic examination. Treatment included dexamethasone and flunixin meglumine administered IV.
