The treatment may be either preventive or surgical. The first is within the reach of everyone owning sheep. Where only a few sheep are owned each individual should be caught and a mixture of tar and lard, or oil of tar and lard, applied to the nostril with a brush. This can be done in a short time and should be repeated every ten days or two weeks during the warm months. Narrow salt troughs may be made and the edges smeared with tar so that the sheep will get tar on their noses when they take salt. Turpentine may be applied high up in the nostril by means of a feather. Begin the preventive treatment early in the spring or whenever you know by the action of the sheep that the fly is bothering them, and you will have better success than to wait until the sheep are affected and undertake to cure them. =BOTS.=--See Bot Flies. =BROKEN WIND.=--See Heaves. =BRONCHITIS.=--A common disease of domestic animals attacking the bronchial tubes. It may be chronic, but is usually acute, and may affect one side or both. The most frequent causes of bronchial catarrh are colds. A sudden cooling of a heated body by drenching, by the breathing of cold damp air, may all bring on the disorder. Dust, smoke or gas, when inhaled, often produces the same trouble. Acute bronchitis usually sets in with a sudden rise of the temperature of the body, and the animal seems to have a chill. This may be quite violent at times. The cough is noticed very much as with people, being short, dry, and husky. Later on, as the disease progresses, a frothy mucus follows the cough. Associated with the disease is a loss of appetite, constipation, and pains in the chest and rattling in the chest and throat. A favorite position of the horse is standing and of other stock that of lying down. Good care is essential in the treatment. That means, with good treatment, dust, smoke, and bad air are to be severely avoided. Plenty of good ventilation, but no draft; and warm, well-lighted quarters are very desirable. The animal should be blanketed to be kept warm in the early stages and a compress placed over the chest, with blankets over the compress. Frequent changing of this compress is desirable, say a change every hour or two. When the animal is suffering from a chill, stimulants are excellent. A tablespoonful of whiskey in a pint of water and given as a drench every half hour or hour will be helpful.
