The Farmer's Veterinarian: A Practical Treatise on the Diseases of Farm Stock

The Bot-Fly of Sheep

is a very troublesome pest at times, and always causes trouble and annoyance to the flock when present, and occasionally causes considerable financial loss. The fly attacks sheep during the warm months, July and August generally being the worst. The presence of fly in the flock is easily told by the behavior of the sheep. The fly looks much like a house fly, only it is longer and it always attempts to lay its eggs just inside of the opening of the nose. As soon as the fly begins to get near the nostril the sheep will begin to run, will hold their noses close to the ground, and frequently huddle together as closely as possible for protection. When the fly does succeed in depositing the larvæ it begins immediately to work its way up the cavity of the nose and finally gets into the small cavities in the head, where development goes on. It is during this period of development in the head that most of the damage is done. As the grubs grow larger a discharge from the nostril is noticed, which may soon become very thick and sticky, gumming up the nostrils and making breathing difficult. The sheep will often carry their heads low, but will frequently raise their heads and point their noses straight up.

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.

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.

After the chill period is passed, small doses of tincture of aconite, say 10 to 15 drops, in a little water as a drench will assist in discharging the mucus. When the animal has become at ease, a mustard plaster applied to the lungs will help you somewhat. From now on the treatment should be good nursing and good food. Boiled flaxseed and gruel will be very helpful. A very helpful preparation may be made of the following: Nitrate of potash or saltpeter, tartar emetic, ground gentian root, equal parts. A half pound or pound in all should be mixed thoroughly, and then a teaspoonful given three times each day. When all danger is passed, continue the careful handling and allow two or three weeks’ complete rest.
