Encyclopedia Britannica


disorder of ruminant animals involving distention of the rumen, the first of the four divisions of the stomach, with gas of fermentation. Bloated cattle are restless and noticeably uncomfortable and have distended left flanks. Bloat often occurs in cattle that have grazed young, lush legumes such as clover or ingested large amounts of concentrate rations. Though deaths have occurred, economic losses from bloat usually derive from reduction in milk production and weight-gain rate. Treatment involves administration of antifoaming agents and relief of pressure by passage of a stomach tube via the esophagus.
