Forages produced on some high northwestern ranges were analyzed for selenium concentration to determine the hazard of white muscle disease (WMD) in calves and lambs. The selenium concentration in 94 forage samples ranged from 0.01 to 0.78 ppm, of which 20 samples contained more than 0.10 ppm. The remaining 74 samples contained less than 0.10 ppm and 59 of those contained Less than 0.05 ppm. Approximately 90% of the summer ranges studied produce forage containing less than 0.10 ppm selenium. Thus, the hazard of WMD on these northwestern ranges may be high. Ranchers should work individually and in groups to ascertain losses from the disease and minimize them by injecting the animals with selenium.
