Prevention of the disease. — Up to the present time, there has not 

 been discovered any means by which hog cholera can be cured, 

 the only safeguard being prevention. All that is necessary to 

 prevent the disease is to keep the germs of the disease away 

 from the herd. In the vast majority of cases the germ 

 is transported mechanically, in the bodies of sick hogs and 

 on the feet of men or animals, including birds. It follows, 

 therefore, that the chances of an outbreak of hog cholera will be 

 greatly lessened, if not completely avoided, if the herd is pro- 

 tected from these sources of infection. To do this the herd 

 should be placed on a part of the farm that will be least accessible 

 to men or animals from other farms. The hogs should be con- 

 fined to a dry lot free from running water or wallows, unless one is 

 constructed as suggested on page 509, and the disinfectant added 

 every two weeks. Careful attention should be given the feed 

 and water. The hogs should be provided with shade and clean 

 dry sleeping places. 



If at any time any of the animals show signs of sickness, they 

 should be separated from the healthy ones. Air-slaked lime 

 should be scattered about the lot, and the feed troughs thoroughly 

 disinfected or replaced by new ones. For a condition powder 

 prepare the following : — 



Wood charcoal 1 lb. 



Sulfur lib. 



Sodium chloride 2 lb. 



Sodium bicarbonate 2 lb. 



Sodium hyposulfate 2 lb. 



Sodium sulfate 1 lb. 



Antimony sulfite 1 lb. 



Completely pulverize and thoroughly mix. This powder is 

 mixed with the feed in the proportion of a large tablespoonful 

 to each 200 pounds weight of hogs, and given once a day. When 

 hogs are suspected to be affected with cholera, they should not 

 be fed on corn alone, but have, at least once a day, soft feed made 

 by mixing bran and middlings, or middhngs and corn meal, or
