Abstract

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.
