On Jan. 12, 1950, a 9-month-old female bovine of the Angus breed was admitted to Stange Memorial Clinic. Accompanying history stated that recently the animal showed weakness in the shoulders and had an enlargement in the area of the umbilicus. One year previously, two calves in the same herd exhibited similar symptoms. One of these two animals died; the other was slaughtered. No post mortem results on the slaughtered animal were obtained.
