This disease results from the presence of a foreign body. This condition is not rare in cattle, because these animals have the habit of swallowing their feed without careful chewing, and so nails, screws, hairpins, ends of wire, and other metal objects may be swallowed unconsciously. Such objects gravitate to the second stomach, where they may be caught in the folds of the lining mucous membrane, and in some instances the wall of this organ is perforated. From this accident, chronic indigestion results. The symptoms, more or less characteristic, are pain when getting up or lying down; grunting and pain upon sudden motion, especially downhill; coughing; pain on pressure over the second stomach, which lies immediately above the cartilaginous prolongation of the sternum. If the presence of such a foreign body is recognized, it may be removed by a difficult surgical operation, or, as is usually most economical, the animal may be killed for beef, if there is no fever.
