The word "dysentery," as it is commonly used in relation to the diseases of animals, signifies a severe form of diarrhea.

Causes.—Diarrhea is a symptom of irritation of the intestines, resulting in increased secretion or increased muscular contractions, or both. The irritation is sometimes the result of chilling from exposure, improper feeding, irritant feeds, indigestion, organic diseases of the intestines, or parasites.

Symptoms.—Passages from the bowels are frequent, at first consisting of thin dung, but as the disease continues they become watery and offensive smelling, and may be even streaked with blood. At first the animal shows no constitutional disturbance, but later it becomes weak and may exhibit evidence of abdominal pain by looking around to the side, drawing the feet together, lying down, or moving restlessly. Sometimes this malady is accompanied with fever, great depression, loss of strength, rapid loss of flesh, and it may terminate in death.

Treatment.—When the disease depends on irritating properties of the feed which has been supplied to the animal, it is advisable to give a mild purgative, such as a pint of castor or linseed oil. When the secretions of the bowels are irritating, an ounce of carbonate of magnesia and half an ounce of tincture of opium should be shaken up in a quart of linseed tea and given to the animal three times a day until the passages present a natural appearance. When there is debility, want of appetite, no fever, but a continuance of the watery discharges from the bowels, then an astringent may be given. For such cases the following is serviceable: Tannic acid, 1 ounce; powdered gentian, 2 ounces; mix and divide into 12 powders, one powder to be given three times a day until the passages present a natural appearance. Each powder may be mixed with a pint and a half of water. Tannopin is a new remedy that is most useful in such cases. The dose is from 30 grains to 2 drams. Useful household remedies are raw eggs, strong coffee, parched rye flour, or decoction of oak bark. In all cases the food must be given sparingly, and it should be carefully selected to insure good quality. Complete rest in a box stall is desirable. When diarrhea is a symptom of a malady characterized by the presence of a blood poison, the treatment appropriate to such disease must be applied.
