It is customary with some people to examine the teeth of hogs, and if one tooth is found darker colored than the others, it is supposed to be the cause of the hog not doing well, if he is in poor condition, and the tooth is hammered off flush with the jaw, leaving the broken roots, lacerated gums and nerves to increase the hog’s suffering. If the hog recovers, it is often concluded that this was a case of Black Tooth. My advice is, if you are determined to have the tooth out, extract it properly. Do not break it off. When your hogs are not thriving, give them the regulator and tonic prescribed on the first page of this chapter. BLOOD POISONING. (_Pyemia Septicemia_) CAUSE.—Due to the toxic substance produced by germs that invade wounds, bruises, abscesses, or womb following farrowing, if lacerated. SYMPTOMS.—The seat of injury becomes swollen, pus may adhere to the hair, temperature elevated, appetite poor, hog moves about very slowly, becomes separated from the rest of the drove, lies around in some cool, quiet place, eventually becomes very weak and poor and dies, if good attention is not given. TREATMENT.—Separate from the other hogs and remove to a clean, comfortable place and wash the seat of injury with some good disinfectant, as a five per cent Carbolic Acid solution. In cases of abscess, open it low so as to assure good drainage. Keep clean, cool water before your hogs at all times. Give mashes made from wheat bran and hot water, or any good substantial food that is easily digested containing regulator and tonic prescribed on the first page of this chapter. BRONCHITIS. CAUSE.—Lung worms, poorly ventilated sleeping quarters, sleeping in straw stacks, in manure heaps, over-heated, filthy pens, where the animals inhale irritating gases given off the bodies of other hogs, and from filth. Smoke and dust are very common producers of bronchitis. SYMPTOMS.—Breathing fast, appetite poor, slight rise in temperature and coughing. The hog is dull and stupid, refuses food, but drinks water frequently. TREATMENT.—Preventive; avoid the above named causes, but when hogs become affected, move them to clean, well ventilated quarters, avoiding dust and gases, disinfect bedding and floors with some good disinfectant, as Crude Carbolic Acid, sprayed. Also give large doses of the hog regulator and tonic as prescribed on the first page of this chapter. Feed vegetables, or any easily digested food, and hot wheat bran mashes. In case the disease is due to lung worms, confine the animals in a closed shed and permit them to inhale the steam from Turpentine and water for a few minutes, by placing water and Turpentine in a tin receptacle holding about two gallons, and inserting heated bricks or stones into the solution.
