Capture myopathy in a captive Black-bellied Whistling Duck

Abstract

A female captive-raised Black-bellied Whistling Duck exhibited signs of capture myopathy within 24 hours after a strenuous capture. Serum creatine kinase activity 48 hrs after capture was 23,680 IU/L and aspartate aminotransferase activity was 898 IU/L. Postmortem lesions included large, pale areas of muscle tissue in the hind limbs and heart. Histologic lesions of skeletal muscle included severe myofiber degeneration and necrosis with mineralization, interstitial hypercellularity, and occasional areas of dense fibrous connective tissue scarring.
