ERGOTISM.
—A parasitic fungus that grows on different species of grass and produces in one stage of its development black or purple enlarged spurs causes ergotism. The disastrous effect of ergot seems to appear in the late fall and winter, when hay or straw infected with ergot are continuously fed. The animals will be troubled with irritation of the bowels and a sloughing off of the extremities. Frequently the animals lose parts of their tails or ears or hoofs. In others, gangrenous sores appear. In the early stages of the poisoning the symptoms are not clearly marked. The best treatment is secured by an entire change of food, so as to remove the cause, and then to follow with good laxative food. Of course, medicinal treatment will not be satisfactory if an important part of the animal like the hoof were to be destroyed. So much expense would be connected with keeping the animal until a new hoof had been formed that it is better at the beginning to destroy the animal unless very valuable. Where sores only manifest themselves such treatment as given an ordinary wound will be efficacious, provided food absolutely free of ergot is supplied.
ERYSIPELAS.
—An inflammation of the skin and tissues beneath. Owing to a blood poison, it is characterized by a swelling and hardness of the affected parts which has a tendency to spread and form abscesses. In horses and cattle, erysipelas is nearly always the result of wounds and generally of those in the legs of animals weakened by hard work and poor food, or else in young animals whose blood is vitiated by the poison of glanders or some other animal contamination. The disturbance is noticed on the third or fourth day after the injury in the immediate neighborhood of the wound. The skin is swollen, smooth, hot, tender, and painful. The swelling gradually extends around it, sometimes deep into the muscles. The surface is hard and tense, but often when the finger is firmly pressed upon it and withdrawn a depression is left. In severe cases chills occur, the pulse is weak and quick, the breathing hurried, the bowels constipated and the urine scanty and highly colored. There is considerable thirst, but no appetite. A brisk purge is the first step in treating. Follow the purge with tincture of chloride of iron, 4 teaspoonfuls in a pint of water. Give this every three or four hours. At the same time give internally 4 tablespoonfuls of hyposulphite of soda in a pint of water three times a day. Externally bathe the wound with the following mixture: Tincture of chloride of iron, 4 tablespoonfuls, and alcohol one pint. Another good ointment is sugar of lead 4 tablespoonfuls in a pint of water. This should be applied with a wet cloth to the diseased parts.
