HOG CHOLERA, also known as Swine Fever, a malady affecting hogs, of which the chief symptoms include excessive diarrhcea, purple coloring of the skin, lack of appetite, general irritation and inactivity. The virus has been located and is filterable, and is usually conveyed by the water supply. The seat of the disease is in the lungs and intestines and there is much inflammation. The per centage of loss from this disease is very large.
There are different varieties of the disease, and two kindred maladies, hog cholera and swine plague, often set up a complication in the same hog. Physi cians, however, have differentiated be tween the two, the former usually at tacking the intestines, and the latter usually attacking the lungs. The prin cipal symptom in hog cholera is in the discoloration of the skin; in the other the animal usually suffers from a con tinual cough. Very often the disease cannot be correctly diagnosed till after death, when the character is indicated by the lesions in the lungs, the intestinal canal or abdominal lymph glands.
The disease is contagious and the methods of counteracting it when it af fects a herd have to be drastic. The
affected hogs have to be segregated, and the pens and surroundings in which they have been confined have to be burnt. Even the ground has to be put into dis use, and the bacilli must be destroyed by putting it into a state of cultivation if it is intended again to use it as a hog yard. The water has to be carefully ex amined, and the pens kept clean and occasionally whitewashed.
Just as there are varieties in the mal ady so there are degrees in its virulence. In serious cases the hog may die at the end of a couple of days. In a less se rious case the animal may continue sick for a period of about five weeks. Hogs have been successfully immunized. The most successful method has been to in Net the immune serum into one side and blood from a hog sick with the malady m.to the other. Tonics containing so dium salts and sulphur have also had good effects.
(hog,en-mogfen), a sobriquet for Holland, a corruption of ooge en Mogende ("High and Mighty"), the Dutch term of address to their States General.
