MANGE.
(Scabies)
Cause.—Mange is a contagious disease, produced by the presence of a small parasite that varies in length from a fiftieth to a hundredth of an inch, according to the species, of which there are three: Sarcoptes, which generally affects the withers; Symbiotes Communis, affecting the legs, and the Psoroptes Communis, which affects horses about the root of the tail and mane. The latter is one most commonly found affecting horses. They multiply rapidly and are spread from diseased to healthy horses by their bodies coming in contact with one another, or by corrals, stables, railroad cars, etc., recently occupied by mangy horses.
Symptoms.—The mange mite attacks the skin and produces a thickness of its outer surface, covering it with crusts and scabs, with a consequent loss of hair. Intense itching accompanies the disease, and affected horses continually bite and rub themselves.
Psoroptic Mange commences at the root of the tail, or at the roots of the mane on the neck or withers, and gradually spreads over the back, up to the head, over the sides, and finally affects the entire body. In cases of long standing the skin becomes ulcerated, the animal becomes greatly weakened, emaciated and finally dies.
Treatment.—When a large number of horses are affected (in one locality) it is best to prepare a vat and dip them, under the supervision of the United States Bureau of Animal Industry. When just a few horses become affected, the following has proven very effective: Sulphur, eight ounces; Oil of Tar, eight ounces; Sweet Oil, two quarts. Mix and apply liberally to the parts affected. A few applications are generally sufficient to eradicate the disease.
