on its breast and, when urged to move, will have violent fits of coughing. 

 Some will vomit stringy mucous the first day, markedly tinged with bile; 

 eyes are red, swollen, and weeping; the discharge from the nose is often 

 streaked with blood; and there is a loss of appetite in the acute febrile 

 st.ge, which usually returns with the drop in temperature in two or three 

 days. 



Thrifty, growing shoats and young hogs are most susceptible. Thin, 

 poorly fed and unthrifty hogs seem to be singularly free from the disease. 

 The treatment for this disease is almost entirely hygienic, placing the herd 

 in dry, clean, well-bedded quarters, with plenty of fresh air and free from 

 draughts, an abundance of clean, fresh water, and little or no food for 

 twenty-four hours. Usually a herd that is affected in this way will recover 

 without any other treatment. 



Hog cholera virus should not be given to hogs suffering from this dis- 

 ease and, if cholera appears in the herd while in this condition, serum alone 

 treatment should be given and followed later by the simultaneous method 

 to insure lasting immunity. 



NECBOTIC ENTERITIS. 



Necrotis enteritis is a disease of pigs which may be mistaken for hog 

 cholera and which results in great losses to hog raisers in Illinois. That 

 this disease does exist independent of hog cholera is established and al- 

 though it may stimulate hog cholera in some respects, there are diagnostic 

 features that sharply define this disease. 



It is quite apparent that the causal organism is of the group which in- 

 habit the intestinal tract and infect soil which is rich in decayed vegetable 

 matter. The warm rains of spring and fall seem to favor the growth of 

 these organisms, as the disease is prevalent at these periods. When a hog 

 lot, which is low and wet, once becomes infected, the disease persists year 

 after year. Pigs pick up the infection with their food. Suckling pigs may 

 become infected when the sow's teats are contaminated. The age predis- 

 poses to infection, as the disease is seen in pigs up to six months, most 

 frequently showing from the second to the fourth month; older hogs seem 

 to be resistant. The disease is sometimes seen after lye or other caustic 

 agents have been fed. 



The disease assumes a chronic character, the pigs show a general un- 

 thrifty appearance, lack of growth, the hair looks dead, the skin dry and 

 scurvy, the feces being thin, yellowish, and peculiarly offensive, while the 

 pig becomes emaciated, yet has little temperature, and the appetite usually 

 persists throughout the disease, which is a marked contrast to cholera. 



The treatment for this disease is largely through sanitation. After 

 separating the well from the sick, remove the well to a clean pasture if in 

 summer; in the winter, remove to a clean, dry, sheltered place, disinfect 

 houses and troughs with standard disinfectant and lime; plow up infected 

 lots if possible. Many pigs may be saved in the early stages by treating 

 with intestinal antiseptics and mineral or linseed oil. Feed soft feeds, and 

 see that the drinking water is pure. Do not inject virus into pigs in this 

 condition. If cholera should appear in a herd affected with necrotic en- 

 teritis, use serum alone and, after the hogs have recovered, retreat with 

 serum and virus to insure lasting immunity from cholera. 



HOG CHOLERA SYMPTOMS AND TREATMENT. 



The symptoms of hog cholera differ in different hogs and in different 

 herds, depending upon the strength of the germs and the resisting power of 

 the hogs. As a result of these variations the disease has been said to exist 

 in two forms, acute and chronic, though the germ is the same in both. In 

 the acute or severe type hogs sicken and die quickly, so that the farmers 

 will say that a hog which is found dead in the morning was well the night 

 before. In the chronic or less severe type hogs may be sick for weeks or 

 months before they succumb.
