CHAPTER THIRTY-TWO. 



HOG CHOLERA AND ITS PREVENTION BY THE 



SERUM-SIMULTANEOUS METHOD OF 



TREATMENT. 



In accepting the invitation of the author of this 

 book to write this chapter on the subject of Hog 

 Cholera and its Prevention by the Serum-simultaneous 

 Method of Treatment I did so with the idea that I could 

 talk as one breeder to another, and with the hope that what 

 may be said may lead to a more active and persistent cam- 

 paign against a disease that, judging by the results at- 

 tained at lowana Farms, and elsewhere where the treat- 

 ment has been given a fair and intelligent trial, can be 

 prevented and ultimately wiped out. 



Aside from the purely elementary scientific state- 

 ments that are made in order to give a clearer under- 

 standing of the nature of hog cholera as a disease, of 

 what is meant by immunity, and of the process followed 

 in obtaining serum, the statements made and the con- 

 clusions drawn are based entirely upon our work with 

 registered swine. They show what we have accomplished 

 and the policy we have permanently adopted in preventing 

 the disease. The results have been very gratifying to us, 

 and have enabled us to prevent the enormous loss which 

 almost inevitably follows when a hog cholera epidemic 

 strikes a herd. If our experience, with the results attained 

 and the conclusions drawn, can be of benefit to the swine 

 breeders of the country, we are glad to make known what 

 we have done, and to do our part towards stamping out a 

 disease that is annually causing the loss of tens of millions 

 of dollars throughout the United States.
