On September 25, 1959, a Holstein bull calf was presented at the Stange Memorial Clinic. The history given by the client pointed out that the calf had been sold at a sales barn at four days of age because it could not successfully nurse its dam. Milk would run out of the nostrils while it attempted to nurse.
