SYMPTOMS.—These may appear suddenly, but always soon after the animal has been feeding, generally on returning from the field; they may, however, occur in the stable. The animal ceases to eat or ruminate, is swollen or “blown” over the whole belly, but particularly at the flanks or left side, where the distended stomach lies. The rumen is enormously swollen, the pillars of the œsophagus are tightly closed, thus preventing the escape of gas; and the greater the distention the firmer is the closure of the œsophagus. The swelling yields when pressed by the finger, and gives forth a hollow sound, like that from a drum when it is struck. There are also sour and noisy belchings of wind; the cow does not move, moans, and is evidently in great distress. The distended rumen presses on the diaphragm and impedes the action of the heart and lungs, causing shortness and difficulty of breathing; the nostrils are widely dilated, and there is a threatening of suffocation. As the disease advances, the pulse becomes hard, full, and quicker than before; the eyes are bloodshot, glazed, fixed and prominent; the mouth is hot and full to dripping of frothy slaver; the tongue hangs out; the veins of the neck and chest are distended with blood; the poor beast crouches, with its back bent up; the legs are drawn under the body; the tail is curved upward; the anus, which is closed, protrudes. The body is now covered with cold sweat; the animal stands in one place, continually moans or grunts, trembles, totters, falls, struggles violently, ejects from mouth and nose sour fluid mixed with solid food, and at length sinks and dies, either from suffocation or rupture of the stomach. TREATMENT.—This is the same whether the distention is from gas or impacted food. F.F. may be given a dose every quarter or half hour. We give the method of puncturing, which, however, need never be resorted to if the F.F. be administered.
