■Anti-Hog Cholera Serum. 

 (The only known preventive for hog cholera.) 



There are thousands of dollars spent annually for so-called sure hog 

 cholera "cures." Agricultural papers are full of very attractive adver- 

 tisements of fake remedies. To spend money for such "fakes" is 

 nothing less than throwing it away. 



It would be well to bear in mind that all i:)roducts advertised as "cures" 

 for hog cholera are worthless ; also that a large per cent of the serum and 

 vaccines will not prevent hog cholera. 



Anti-hog cholera serum, if properly prepared and administered will, 

 without a doubt, prevent hog cholera but very little is claimed for it as 

 a curative agent. 



"Wats of Yaccinating. 



There are two ways by which hogs may be vaccinated with anti-hog 

 cholera serum, the Serum Alone Method and the Serum Simultaneous 

 Method. The Serum Alone Method consists of injecting the required 

 amount of serum into the tissues of the hogs with a hypodermic syringe. 

 The Serum Simultaneous Method consists of injecting the serum as in 

 the Serum Alone Method, but at the same time a small amount of virus 

 is injected. 



The Serum Alone Method only confers immunity for a very short 

 period, varying from four to eight weeks, whereas the Serum Simul- 

 taneous Method confers immunity, varying from a few months in very 

 young pigs to life immunity in older hogs. 



As there is considerable danger attached to the Serum Simultaneous 

 Method, it is not safe to put this method of treatment into the hands 

 of persons who have not had special training for this purpose. This 

 is so because a small per cent of the hogs treated by this method develop 

 hog cholera and die. This is so when the method is applied by men 

 who have had long training and wide experience in using the serum 

 and virus. We think it would be a great mistake to distribute the virus 

 with the serum over the State to any one applying for it. If this was 

 done we would expect to see the entire State sooner or later "fired" with 

 hog cholera. There is no danger of producing hog cholera by using the 

 Serum Alone Method, and for this reason we think it is the only 

 method to place in the hands of the untrained. 



The serum is sent direct to any one ordering it, with full directions 

 for using. If the directions are followed closely good results will follow. 

 It is always better, whenever possible, to have some one inject the serum 

 who has at least seen it injected, if they have not done so themselves. 

 Our advice would be to employ a graduate veterinarian when possible 

 and have him inject the serum for you. 



How AND When to Use Serum. 



The Serum Alone Method only gives temporary immunity lasting from 

 four to eight weeks, an average of about six weeks. It is rather expensive 

 to keep a herd of hogs immuned by his method. We believe it would 

 be cheaper where a permanent herd is to be kept for breeding purposes
