A registered 6-year-old Hereford cow entered Stange Memorial Clinic on Dec. 30, 1949 with a history of having been ill since Nov. 21. A tentative diagnosis of traumatic gastritis had been made in the field immediately after her illness was noted. Treatment given at this time by the attending veterinarian was 1 million O.U. of penicillin. The same dosage of penicillin was repeated on Nov. 22. The cow appeared much improved and her temperature returned to normal.
