A month-old calf was admitted to the Iowa State College Veterinary Clinic on Jan. 20, 1941. The calf would drink milk sparingly, and the abdominal cavity appeared to be distended with gas. The owner reported that as long as the calf was nursing the cow it appeared normal, but when "pail-fed" again, it promptly bloated. The owner had given the calf a cathartic a few days previous to its entry into the clinic, but reported negative results. The calf's visible mucous membranes were "muddy," which was evidence of a possible toxemia, but otherwise it appeared to be in fair condition.
