SERUM TREATMENT.—This is successful in some cases, and in others unsuccessful. The latter perhaps is due to poor serums, or the disease being so far advanced in its progress that the hogs are beyond recovery. Serum treatment is very expensive and, as it requires a strictly septic operation of injecting the serum, the average hog raiser or grower is not qualified to administer the treatment properly. An additional and necessary expense is the services of a Veterinary Surgeon. Therefore, I strongly urge adoption of preventive measures as stated. Use some good disinfectant, such as Crude Carbolic Acid, which destroys the Bacillus of Hog Cholera. Also administer hog regulator and tonic as prescribed on first page of this chapter. This will expel worms, tone the system, regulate the bowels and fortify your hogs against Hog Cholera. INDIGESTION. CAUSE.—Worms are perhaps one of the most common causes. Unwholesome, irritating food or swill containing soap or washing powder have a tendency to derange the process of digestion. SYMPTOMS.—Abdominal pain, vomiting, back arched, breathing rapid and temperature elevated from two to three degrees. There may be diarrhoea or the animal may be constipated. Vomiting, as a rule, relieves acute attacks by expelling the irritant from the bowels. When it takes a chronic form, the hogs become stunted. TREATMENT.—Endeavor to find out the cause and remove it. If constipated, give Calomel, fifteen to twenty grains, or, if diarrhoea appears, give hog regulator and tonic as prescribed on first page of this chapter. Feed with hot wheat bran mashes. This will expel all worms and aid digestion. JAUNDICE. (_Yellows_) CAUSE.—Liver flukes, intestinal worms, gall stones, lack of exercise, overfeeding, or a stoppage of the bile duct. SYMPTOMS.—The white portions of the eyes take on a yellow color, as do the membranes of the mouth, back arched, hair looks rough, vomiting, temperature elevated, constipation, although diarrhoea is sometimes noticed. The urine is passed frequently, and is of a dark amber color. TREATMENT.—This disease requires careful feeding and plenty of exercise. Give Calomel, ten to twenty grains, then follow with large doses of regulator and tonic as prescribed on first page of this chapter. It is important in this disease, especially if due to worms. Feed clean swill and vegetables. Give hogs all the pure water they will drink. KIDNEY CONGESTION. CAUSE.—Hogs are subject to various injuries about the kidneys, due to a large number of hogs piling up, exposure to cold, wet rains, etc. SYMPTOMS.—Small quantities of dark colored urine are passed frequently, appetite poor, no energy to move about. Hogs lie around a great deal; at times they may be paralyzed and drag their hind quarters.
