Widespread skeletal myodegeneration in cattle was associated with a disease syndrome characterized by an afebrile course, abnormally dark red urine, incoordination, recumbency, and death. The plants Cassia occidentalis or Cassia obtusifolia grew in the pastures and has been grazed by affected cattle, and appeared to have caused the disease.
