Feedlot bloat

Perhaps the most serious thing that can go wrong with a ruminant on corn is feedlot bloat. The rumen is always producing copious amounts of gas, which is normally expelled by belching during rumination. But when the diet contains too much starch and too little roughage, rumination all but stops, and a layer of foamy slime that can trap gas forms in the rumen. The rumen inflates like a balloon, pressing against the animal’s lungs. Unless action is promptly taken to relieve the pressure (usually by forcing a hose down the animal’s esophagus), the cow suffocates.
