CAUSE.—Investigations lead us to believe that it is due to protozoa. So far, the true micro-organism has not been discovered. This disease is very contagious and is transmitted by direct communication but not through the air. Perhaps the most common way of transmitting the disease is by the hands of the milker. SYMPTOMS.—A slight rise in the temperature, especially that of the udder and teats. They are red, swollen and tender and after three or four days small pimples or pustules will appear on the teats, about the size of a pea. The pimples or pustules become larger and within a few days may attain the size of one-half inch in diameter. At the end of the second week the pimples or pustules burst and discharge an amber colored fluid leaving raw sores, which cause the animal to suffer intensely when being milked. The supply of milk is also markedly decreased in this condition. PREVENTION.—A person should not milk both healthy and diseased cows unless the hands are thoroughly washed in a Carbolated Solution; the clothes that are likely to come in contact with the udder, coat sleeves, etc., changed. TREATMENT.—It is advisable to give a physic as it has a very good effect on the blood, such as Aloin, two drams, and Ginger, two drams, which is easily prepared and administered by placing in capsule and giving with capsule gun. Also, the application of Zinc Ointment two or three times a day affords immediate relief and causes the sores to heal rapidly. Good results are also obtained by feeding food that is easily digested, as bran mashes, steamed rolled oats and vegetables. DIARRHOEA. CAUSE.—Giving rich succulent foods after being fed on stimulating diets for some time, and such a case may be a benefit to the animal instead of an injury. Turnips, carrots, etc., especially if frozen slightly, are apt to produce it. Also impure and stagnant water which acts as a poison or some irritant in the food, as sand, clay, etc., or it may result from excitement, as driving cattle or shipping cattle in cars when not accustomed to it. Or, it may be the result of an overdose of irritating medicines. Diarrhoea as a rule is not fatal. It is often an effort of nature to relieve the system of some disease, as poison in the blood. The easiest way to get rid of it is by way of the bowels. SYMPTOMS.—It is easily detected. An animal has frequent passages which are of a liquid nature. At first the pulse is but little affected, but after a day or two it becomes weak and slightly increased. If it continues for a few days the pulse increases, the ears and legs get colder than normal, there are slight gripping pains in some cases due to slight irritation or perhaps to slight spasm of the intestines. These pains may increase and result in inflammation of the bowels, especially if the cause is due to stagnant water or irritating drugs.
