On Dec. 21, 1953, a three-year-old Holstein cow was admitted to the clinic with the history of having passed only scanty amounts of watery fecal material for ten days. Upon further questioning of the owner, it was learned that she had been off feed for about five days and that at the onset of the condition the first thing he noted was her discomfort while urinating.
