MANGE.
Cause.—There are four different parasites which produce Mange or Scabies in cattle. However, three of these parasites are rarely seen. The Symbotis Communis is the parasite commonly seen in American cattle. These parasites multiply very rapidly and are conveyed from diseased animals to healthy ones by their bodies coming in contact with one another and by healthy animals rubbing against fences, walls, posts, etc., where mangy cattle have previously rubbed.
Symptoms.—Scabs, loss of hair, intense itching, the animals are constantly rubbing or licking themselves. The parts showing the first signs of Mange are those about the croup, or the root of the tail, the neck and withers, but as the disease progresses and no attempts are offered for its eradication, it finally spreads and covers the entire body. The scabs become ulcerated, the animal becomes weakened, emaciated and eventually dies.
Treatment.—Dipping in wood or concrete vats is the most satisfactory method of treating Mange. The regular lime and sulphur dip as recommended by the United States Bureau of Animal Industry is inexpensive and effective.
