  ` j In administering serum, the hogs to be treated should be   g     .
I penned up the night before and handled as quietly and ,,;‘?_ _~ _,iL
{Y expeditiously as possible, and all instruments used in the .   'p‘.ei     rp-- _
  inoculation should be thoroughly sterilized by boiling in V    
  water immediately before the injection or administration.    
. _ Hog cholera serum— is administered with a hypodermic  
  syringe and needle into the muscle of the hog. A conven-  
  ient site is the muscles of the inside of the ham. Hogs too  
  large to throw are snubbed to a post with a rope around   a'-;-  
  the upper jaw, and serum injected into the muscles of the  
neck just_ behind the ear or back of the jaw. It is not con-  
venient to draw the serum from the bottle into the syringe, "  
· and a sterile container must be used. A covered porcelain  
‘ H cup or a tumbler with a saucer for a cover will suffice. The  
container as well as the syringe must be thoroughly boiled  
or washed in a strong disinfectant before using. Before  
making the injection the skin at the site of injection must  
  _ be washed with disinfectant. A 3 per cent. compound solu-  
i . tion of cresol or any of the reliable coal tar dips may be used.  
in , Body temperatures are taken to detect animals infected at  
g -  time of inoculation. Such animals may sometimes be saved  
F, · by administering double the usual quantity of serum, but  
ji uniform results must not be expected in infected herds.  
  l Serum is preventive and not curative. Hogs may be given  
fp the single treatment at any age, the dose of serum depend- -  
L ing on the weight of the animal.   A
