Locoweed (Oxytropis sericea) poisoning and congestive heart failure in cattle.
Locoweed (Oxytropis sericea), when fed to calves at high elevations, increased the prevalence and severity of congestive heart failure. Forced exercise did not increase the prevalence of congestive heart failure, but it did increase severity. Calves consuming locoweed at high elevations developed signs and gross lesions of congestive heart failure and microscopic lesions of congestive heart failure and locoweed poisoning. Calves fed locoweed at low elevations developed only signs and lesions of locoweed poisoning.
