The above must be well powdered and thoroughly mixed. Give one heaping teaspoonful to every one hundred pounds of hog weight. To small pigs, give doses in proportion to weight. Place it in their feed or slop twice a day. In addition to being a vermifuge, it is an alterative and tonic that should be given pigs and hogs which do not thrive properly. Best results are obtained in treatment of Pinworm when the principal food consists of vegetables, mashes and slops. PLEURISY. CAUSE.—Exposure to cold, damp, chilly weather, especially to drafts, or by a large number of hogs being allowed to pile up during cold nights, etc. SYMPTOMS.—Chilling, temperature elevated two or three degrees above normal; breathing fast. The hog will show great pain when pressed over the lungs by flinching, squealing or grunting; couching suppressed, ribs rigid; breathing mostly with the muscles of the flanks; appetite poor and eventually there will be fluids accumulate in the lung cavities. At this stage, the breathing is labored and difficult. If the ear is pressed over the lungs, the fluids can be heard, and in the first stage the sound will be similar to that of rubbing hair between the finger and thumb. TREATMENT.—Remove the cause. The treatment is satisfactory if applied in due time. Place in clean, comfortable shed, seeing that it is well ventilated, omit drafts; apply equal parts of Aqua Ammonia Fort., Turpentine and Sweet Oil over the lungs and give two or four ounces of Castor Oil in milk. Feed easily digested food, such as hot wheat bran mashes, containing hog regulator and tonic as prescribed on first page of this chapter. It is also well to feed vegetables. RHEUMATISM. CAUSE.—Exposure, as in cold, damp houses. Overfeeding also has a tendency to cause swellings of the joints and muscles. SYMPTOMS.—Lameness of one or more limbs, swelling of the joints about the legs and feet. The hog does not care to move, refusing its feed in most cases: temperature slightly elevated; breathing quick and short; he will drink water frequently if offered. TREATMENT.—I am of opinion that Rheumatism in hogs would be a very rare disease if they were properly provided with clean, dry quarters, with a liberal quantity of bedding. Do not allow hogs to pile up, as it is very injurious to them. MEDICAL TREATMENT.—Consists of feeding sloppy food to which add one-half dram of Sodium Salicylate two or three times a day in their feed. Vegetables and green grass are very beneficial in this disease, as they have a cooling effect on the blood. The hog tonic and regulator recommended on first page of this chapter is very beneficial when given with food of a sloppy nature. RICKETS. CAUSE.—Food deficient in mineral matter or lime; filth, lack of exercise, and crowded quarters, all tend to produce a softening of the bones and swelling of the joints.
