Symptoms.—Redness of the skin and the animal rubs itself; is usually confined to a small area at first, but eventually spreads. Considerable inflammation is present, also eruptions of the skin which discharge white, serous, sticky fluid, terminating in scabs and thickness of the skin. Sometimes suppuration or formation of pustules containing pus are present. These symptoms do not always occur in regular succession; in some cases the serums oozing from the skin will be more prominent than in others.
Treatment.—Determine the cause and remove it. If due to poor food, improve the quality. Also feed laxative food, as hot bran mashes, steamed rolled oats. If the bowels do not act freely, administer Aloin, two drams, and Ginger, three drams. Place in gelatin capsule and give with capsule gun. An ointment made from the following is very effective as an application in this condition: Blue Ointment, one ounce; Zinc Oxide, three ounces. Mix well and apply two or three times a day. A tonic usually has a very good effect in the treatment of this disease, and I would recommend the use of the following: Pulv. Gentian Root, four ounces; Potassium Nitrate, four ounces; Ferri Sulphate, four ounces. Mix and make into twelve capsules and give one capsule two or three times a day with capsule gun.
ERGOT POISON.
(Ergotism)
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.
FLUKE.
(Liver and Lungs)
Cause.—This disease is contracted by cattle grazing on marshy lands. There are two different species of Fluke that affect the liver and lungs of cattle. They are both flat, leaf-like worms. The Common Liver Fluke is about one-half inch long, while the so-called American Fluke is somewhat larger. In their life history these Flukes depend on snails as intermediate hosts. At a certain stage of development the young Flukes live on snails. They become encysted on stalks and blades of grass which are finally swallowed by grazing cattle. This disease is most frequently seen in young cattle.
