140 Forty Years' Experience of a Practical Hog Man. 



Our method of procedure in giving the simultaneous 

 treatment may explain in part the reason for our freedom 

 from loss following its application. 



In beginning the work of immunizing our herd we gave 

 each animal a regular dose of simple serum alone. This 

 was given as a preparatory treatment. Fourteen (14) days 

 later we gave each animal thus treated the double or simul- 

 taneous treatment, using the virus and the regular amount 

 of serum. The preparatory treatment paved the way for 

 the simultaneovis treatment 14 days later, and rendered 

 the animal better able to stand the latter treatment. 



In treating pigs whose parents are immune, we give the 

 simultaneous treatment at once, and without the prepara- 

 tory dose. We usually treat our pigs about two weeks be- 

 fore we wean them. 



Hogs and pigs being treated should be given a clean, 

 dry place to house in, plenty of cool, clean water, and all 

 heating and heavy feeds should be discontinued for a couple 

 of weeks. 



In case any animal, given the simultaneous treatment, is 

 not doing well as a result of the treatment, give it another, 

 a double dose of simple serum. This will help carry it 

 through the fight. 



While we recognize that the giving of the above so-called 

 preparatory dose of simple serum doubles the cost of im- 

 munizing hogs and pigs, yet the total absence from loss 

 of animals by such practice fully justifies, in our minds, 

 the added expense thus incurred. And especially is this true 

 where the treatment is being given to pure-bred, registered 

 stock. 



Our observations in treating breeding stock have led us 

 to adopt the following practice : We never give the simul- 

 taneous treatment to bred sows, nor do we breed sows 

 within two or three weeks after treating them. Further, 

 boars just treated should not be put into immediate service. 

 Time should be allowed for the immediate after effects of 

 the treatment to wear off and the animals to regain their 

 normal and active condition. 



The results of our experience in following out this prac- 

 tice have removed from our minds all fear of cholera 

 epidemics. We do not hesitate to move animals from one
