The Prevention of Hog Diseases 469 



The most prominent symptom in sore throat and 

 bronchitis is coughing. Paroxysms of coughing may occur 

 when the hog gets up from its bed and moves about. 

 Young hogs may not thrive, but the appetite usually 

 remains good. If the hog has pneumonia or pleurisy, it 

 is usually seen lying in its bed. The animal gives evi- 

 dence of loss of appetite, displays abnormal rapid breath- 

 ing, and shows elevation of body temperature during the 

 first stage of the disease. 



It is unnecessary to use drugs for the treatment of 

 non-specific respiratory diseases. All that is necessary 

 is special attention to the quarters and diet. A well- 

 balanced ration should be fed to hogs in order to keep 

 them thriving. They should not be allowed to lie in 

 dusty places, straw stacks, manure heaps, or damp 

 quarters. Shady places where hogs are sure to lie during 

 the hot weather usually become very dusty. It is best 

 to wet down the dust in such places and afterwards 

 sprinkle them over with crude oil. Danger from un- 

 ventilated damp sleeping quarters and drafts can be 

 avoided by proper construction of hog-houses; careful 

 attention should be given here. 



Good nursing is the most important treatment for hogs 

 having pneumonia. A clean comfortable bed and well- 

 ventilated quarters should be provided. From ^ to 2 

 ounces of linseed-oil may be given and the dose repeated 

 after an interval of two or three days. 



The only satisfactory treatment for specific pneumonia 

 or pleuro-pneumonia is prevention. This is based on 

 sanitation, as a successful vaccine is not available. Hog 

 cholera caused by the filterable virus with its complica- 

 tion pneumonia can be successfully treated with anti- 

 hog-cholera serum.
