Capture myopathy in Wild Horses-

Capture myopathy is a complex, often fatal, stress- and exertion-induced degenerative muscle condition that affects wild animals, including wild horses and burros . For advocates dedicated to protecting wild horses during roundups, holding, and adoption, understanding this condition is crucial. It is not an infectious disease, but rather a catastrophic physiological failure triggered by the extreme stress and physical exertion associated with pursuit, capture, restraint, and transportation.

Capture myopathy—also known as exertional rhabdomyolysis, capture stress, or white muscle disease—is a non-infectious metabolic syndrome characterized by severe muscle damage (rhabdomyolysis) and systemic organ failure .

Wild horses are prey animals. Their evolutionary survival relies on the "fight-or-flight" response. When subjected to prolonged pursuit by helicopters, separation from their family bands, and confinement in trap pens, their natural stress response is pushed beyond physiological limits . This overwhelming stress, combined with intense physical exertion, initiates a cascade of metabolic failures that can lead to death within minutes, days, or even weeks after the initial capture event .

And importantly, prevention is far more effective than treatment. Once obvious clinical signs appear, the prognosis can be poor
