healthy hog or the larger dose which is essential for those showing 

 evidences of cholera, and he also knows whether it is wise to give the

Before making an injection, either of serum or of virus, the skin 

 covering the point selected should be cleaned thoroughly and washed 

 with a disinfectant. The needle is then inserted through the skin 

 for a distance of about 1 inch so that the point rests in the loose 

 tissues immediately beneath. As the injection is made slowly, the 

 needle may be withdrawn very gradually. Not more than 10 cubic 

 centimeters of serum in the case of small pigs, nor more than 30 

 cubic centimeters in the case of larger animals, should be injected in 

 one place, and when virus also is used it should be injected on the * 

 opposite side of the body or at least some distance from the serum. 



CARE OF HOGS AFTER TREATMENT. 



Success in the treatment of infected herds will depend greatly upon 

 the care given the hogs after treatment. They should be retained in 

 small inclosures, which should be cleaned daily and sprayed with a 

 disinfectant until the disease has abated in the herd. All dead hogs 

 should be properly disposed of at once. Under no circumstances 

 should sick hogs be allowed to roam over areas which it would be 

 difficult to disinfect, nor should they be allowed to come in contact 

 with healthy hogs. During the first week or 10 days after treatment
