Myopathy and myoglobinuria in feedlot cattle.
Myopathy and myoglobinuria occurred in a group of feedlot cattle in Alberta following transportation. The condition was associated with a deficiency of selenium (Se) in grain and hay fed to these animals on their premises of origin. Clinical findings in affected animals were characterized by a normal body temperature, stiffness, sternal recumbency and the passage of red or coffee-colored urine. Treatment with injectable Se-vitamin E was followed by the recovery of most affected animals within two weeks.
