LUNG WORMS.
Cause.—By thread-like worms varying in length from one-half to one and one-half inches and of brownish-white color. They are found in the windpipe and tubes leading into the lungs. The adult worms in the lungs produce large quantities of eggs, which are coughed up with mucus and become scattered over premises where other hogs are permitted to walk. The hogs inhale the dust containing the eggs into their lungs, where the eggs find moisture sufficient for their development.
Symptoms.—Severe coughing spells. Large quantities of mucus will escape from the nose and mouth. The hog becomes stunted, although he may eat fairly well, but if not relieved, the worms collect in the Bronchi and produce sudden death due to suffocation. The worms may set up an inflammation of the lining membranes of the lungs, which is sometimes taken for Swine Plague, or Cholera. This disease is not uncommon, especially in old, filthy, poorly drained hog houses and pastures.
Treatment.—Confine the affected hogs to a shed; close the windows and doors and any large cracks, then compel the hogs to inhale steam from the following mixture: Turpentine, eight ounces; Pine Tar, one pint; Water, two gallons. Place in tin receptacle in center of the shed and heat the above solution by adding hot bricks or stones to the mixture occasionally. Compel them to inhale this steam for at least thirty minutes twice a day. Feed wholesome food to which add hog tonic as prescribed on first page of this chapter. A strong, vigorous hog may have worms, but it retains its vitality so long as it is well fed.
