days. Hogs that have cholera are stupid and life- 

 less and refuse to move. They lie huddled together 

 or retire to a corner of the pen. Some will eat 

 while others will not. No cure for hog cholera has 

 been found except anti-cholera serum. (Farmer's 

 Bulletin 379 tells how to prevent hog cholera.) 



There are other diseases such as mange, paraly- 

 sis, and black tooth. The most satisfactory way to 

 give medicine to hogs is in their food, but it is 

 always a good plan to know how to prevent disease 

 in the first place. 



Lice. If the herd is troubled with lice the hogs 

 may be dipped in a coal tar disinfectant to be had 

 at the drug store. Directions for using it are also 

 given. In summer crude oil may be poured on the 

 water in the wallow. This will cling to the hogs 

 and kill the lice without injury to the hog. Gunny 

 sacks soaked in crude oil may be wrapped around 

 a rubbing post in the hog lot.
