On December 14, 1944, an 8-month-old Hereford steer was presented at the Stange Memorial Clinic with the following history. The steer had been noticed about five or six days previously showing difficulty in urination. The patient could urinate some but only slightly. There was no blood noticed in the urine and there was considerable straining during micturation. Rumination had stopped two days before he was brought to the clinic. The owner of this calf has had several cases similar to this in this feeder calves every year.
