Cause.—Ergotism is produced by cattle eating fungoid growths which attack kernels and seeds of rye and blue grass, etc. These kernels or seeds grow dark in color and become abnormally large and curved in shape. The infected grass or hay when eaten by cattle contract the arteries, especially those of the legs, just above the feet, although all the arteries in the body are contracted to a certain extent. This disease is frequently seen in Spring and Summer.

Symptoms.—Ergot is prescribed in cases of bleeding, because of its contracting effect upon the arteries (closing or stopping the flow of blood) where the blood supply is the weakest, as in the extremities. It is cut off and this, of course, causes the skin just above the hoofs to break or crack as though it were cut with a knife. This shuts off the entire supply of blood to the foot, which mummifies, and the lower portion becomes gangrenous and eventually sloughs off. One of the first effects of Ergot Poison in pregnant cattle is abortion, due to the blood supply to the womb being shut off by its contracting effect on the arteries. Cattle are particularly susceptible to Ergotism.

Treatment.—When Ergotism is so advanced as to produce sloughing of the feet it is best to destroy the animal. If other animals are affected slightly, find out the cause and remove it. Look to the hay or pasture as the producer. Administer one-half ounce of Chloral Hydrate, two or three times a day in their drinking water or mix it with sufficient quantity of Flaxseed meal to fill an ounce gelatin capsule and give with capsule gun. If the skin is slightly broken above the foot, wash with five per cent solution of Carbolic Acid. Where the feet have become gangrenous amputation of the foot or feet is necessary, which is not advisable unless the animal is very valuable.
