_Symptoms._ The fæces are hard and firm, glazed on the surface, coated with mucus and sometimes stained with blood. They are passed in small quantity and with much effort and straining, and finally the bowels become completely blocked, nothing whatever being passed. Tympany of the rumen now appears, especially after feeding, appetite and rumination fail, there is much dullness, debility, and loss of flesh and unless relieved, the animal dies in marasmus. Pressure on the right side of the abdomen made suddenly and forcibly produces a sound of liquid splashing in an air space, derived apparently from the accumulation above the obstruction. The oiled hand introduced into the rectum may feel the solid impaction, but in any case causes pain and moaning when the seat of the impaction is pressed upon. _Treatment._ In the milder cases and earlier stages a change to sloppy food, green food, or boiled flaxseed, with plenty of salt, free access to water, and scruple doses of nux vomica may prove successful. In the more advanced conditions with complete obstruction, give ½ lb. to 1 lb. each of sodium chloride, and sodic sulphate, and ½ dr. nux vomica, inject hypodermically 3 grs. eserine or 7 grains barium chloride, give water _ad libitum_, and frequent and large injections of soapsuds. If these latter are given cold they will still further stimulate the missing peristalsis. In obstinate cases a second dose of the salts, or 1 quart of castor oil may be given with the addition of 20 drops of croton oil. When relief has been obtained, a laxative and nutritive diet and a course of bitters should follow. INDIGESTION WITH OBSTRUCTION OF THE COLON IN SWINE. Causes: green leguminosæ, dew, rain, dry indigestible food, lack of water or exercise, debility, torpid liver. Symptoms: firm, small, coated stools, obstruction, straining, tympany, rumbling, vomiting, anorexia, lies on belly, secludes himself, restless, grinding teeth, diarrhœa. Diagnosis from hog cholera. Treatment: laxatives, enemata, antiferments, rubbing, massage, mechanical unloading of rectum, puncture, dieting, bitters. _Causes._ The leguminosæ in their green state are liable to produce indigestion and flatulence in the pig. If covered by dew or rain this tendency is increased. Dry, fibrous or indigestible food with privation of water and of exercise tends to intestinal impaction. Debility from any cause, by weakening the contractility and secretory power of the bowel strongly predisposes to this condition. Torpid liver with diminished secretion of bile is another common factor.
