 or mixed with raw eggs well beaten. 



A serum, the Dorset -Niles serum, is now prepared 

 that gives excellent results in protecting swine against 

 cholera. It is prepared by giving an immune hog large 

 doses of virulent blood, which makes the hog hyper- 

 immune. Blood serum from a hyper- immune hog 

 when injected into a susceptible or non- immune hog 

 gives it immunity against hog cholera for several 

 months. This is called the "serum alone" method. If, 

 at the same time the serum is injected, the hog is also 

 given a dose of virulent blood, a permanent immunity 

 is established. This is called the "serum -simultaneous" 

 method. The serum alone can be administered by any 

 careful person that follows directions. The serum - 

 simultaneous treatment should be administered only by 

 a qualified veterinarian, as there is danger of dissemi- 

 nating the disease from the virulent blood used. 



The dose of serum will vary according to the size of 

 the hog to be vaccinated, from ten to sixty cubic centi-
