Perhaps the greatest damage brought about with cattle afflicted with the chronic form of abortion is the shortage of milk. Animals afflicted with accidental abortion show very few marked symptoms before they abort. Animals afflicted with contagious abortion have a number of marked symptoms, namely, little red patches of infection on the lining of the vulva, and there may also be present a catarrhal discharge. The sheath of the herd bull in the acute form of the disease has a catarrhal discharge, while the symptoms of calves is a swelling of the glands of the throat from ear to ear. These last named symptoms do not appear in accidental abortion. Owing to the fact that the germs of contagious abortion are found in the mothers’ blood, in the genital organs of the cow and the bull, and in the stables wherein they are housed, it has been positively decided that the only reliable and effectual treatment for contagious abortion is the hypodermic treatment, which destroys the germ in the mother’s blood. The genital organs of the cow and bull should be washed out with the antiseptic solution made of 1 pint of corrosive sublimate to 1,000 parts of water, and the germs contained in the stables wherein afflicted animals are housed should be destroyed by disinfectants. In this way the disease is met at every turn, and it is impossible for the disease of contagious abortion to exist when thus handled. =ABSCESS.=--A collection of pus in a new-formed cavity in the body. It has a well-defined wall surrounding it. An abscess is the result of entrance of micro-organisms into the body. They may have entered through wounds or into the hair follicles, or abscesses may result from infectious diseases, as strangles or distemper in the horse. At the seat of the abscess formation swelling occurs, the part feels warmer than the surrounding tissue, is painful to touch, and hard. These conditions are due to the inflammation of the part. Later it becomes soft, less sensitive, and fluctuates, which shows that it is coming to a head, or that the pus is collecting. If the skin is white it will show a yellow color in the center, which is usually raised above the surface, and the hair falls out. This soon breaks and discharges pus. It is advisable to hasten the ripening of the abscess by hot applications in form of poultices, or a large pack of cotton saturated with hot bichloride of mercury 1 part to 1,000 parts of water, or use some one of the coal tar dips 1 part to 50 parts of water. The application of a light blister will often hasten ripening. When the pus has collected or the abscess has come to a head, it should be opened at the lowest part in order to give free drainage to the pus contained within.
