Definition. Susceptible Genera. Causes; gastric paresis, overloading, cold, fear, exhaustion, poisons, fermentescible food,—new grain, leguminosæ, frosted vegetables, ruminitis, foreign bodies in rumen, microbian ferments. Symptoms, abdominal, general. Gases formed under different aliments—carbon dioxide, marsh gas, hydrogen sulphide, nitrogen, oxygen. Lesions, rupture of rumen or diaphragm, compression or rupture of liver or spleen, petechiæ, congestion of lungs and right heart, of cutaneous and cerebral vessels. Prevention, avoid indigestible and fermentescible aliments, correct adynamic conditions, tonics, avoid injurious ferments, make alimentary transitions slowly. Treatment, exercise, bath or douche of cold water, rubbing and kneading, rope round abdomen spirally, gag in mouth, dragging on tongue, movement of a rope in fauces, probang, stimulants, antiseptics, alkalies, ammonia, oil of turpentine, oil of peppermint, alcohol, ether, pepper, ginger, soda, potash, lime, muriatic acid, carbolic acid, creosote, creoline, sulphites, kerosene, chloride of lime, chlorine, tar, common salt, hypochlorite of soda, magnesia, eserine, pilocarpin, barium chloride, colchicum, lard, trochar, Epsom salts, rumenotomy. Treatment of diseased gullet, mediastinal glands, stomach or intestines. _Definition._ The condition is a combination of paresis of the rumen and gaseous fermentation of its contents. The initial step may be the paresis or in the more acute forms the fermentation. _Genera susceptible._ While all ruminating animals are subject to this disorder, it is much more frequent in cattle and sheep than in goats.
