The treatment recommended in each disease is one I have used and found efficient in my many years of practice as a Veterinary Surgeon. If my readers will study the following chapter carefully, they will save much unnecessary loss to the swine industry and be of great value to the community in which they reside. CHARLES J. KORINEK, V. S. CHAPTER I. HOG REGULATOR AND TONIC. Nux Vomica, one pound; Hardwood Charcoal, two pounds; Sulphur, two pounds; Common Salt, three pounds; Sulphide of Antimony, one and one-half pounds; Glauber Salts, two pounds; Bicarbonate of Soda, four pounds; Hyposulphite of Soda, four pounds; Nitrate of Potash, one pound; Quassia, one-half pound; Gentian Root, one pound; Iron Sulphate, one pound; pulverize and mix well. To every one hundred pounds of hog weight, give one tablespoonful in feed or swill once or twice daily. For hogs weighing two hundred pounds, the dose would be two tablespoonfuls; for a hog weighing fifty pounds, one-half tablespoonful. Hogs, like other animals, require tonics, bowel regulators and worm expellers. For these purposes, I have prescribed under a number of the diseases of hogs, which I cover in this chapter, the above general tonic and regulator which I have used in my personal practice with marked success, especially serving the purpose of aiding hogs in the convalescence from debilitating diseases and in their recovery from a general run-down condition. Aside from its general tonic and regulative effect, this prescription contains nerve tonics, intestinal antiseptics, laxatives, worm expellers, and aids digestion, etc. If regularly given to hogs, and sanitary conditions are maintained, this tonic and regulator will largely fortify them against contagious diseases. ABORTION. CAUSE.—Sows may abort at any state of pregnancy by slipping, falling, receiving kicks, or by being caught while crawling through or under fences. Sows may also abort when allowed to crawl into quarters where there are other hogs. Contagious diseases, such as Cholera and Pleuropneumonia also produce abortion. There is also a contagious form of abortion in sows, but this is very uncommon, as the disease spreads very slowly. SYMPTOMS.—There is no warning given, as a rule; the sows expel their pigs before any signs of abortion are noticed. In other cases the sows refuse to eat, become uneasy, shivering and trembling of the muscles, and straining or labor pains are noticed. As a rule, when a sow aborts, she will not prepare a bed, as she would normally. TREATMENT.—Preventive is the only safe and sure treatment, although when the first signs of abortion appear, and there are no signs of the membranes coming away, remove the sow to quiet, warm, clean quarters by herself, and if straining, give one dram of Chloral-Hydrate in her drinking water every two or three hours.
