HANDLING HOG CHOLERA IN THE FIELD 185 



Careful and experienced men can usually select 

 satisfactory feeders in large stockyards, but on 

 the whole there are unavoidable risks associated 

 with the practice. 



Handling show hogs. Show hogs constitute 

 a separate problem in themselves, because they 

 are of exceptional value, and because they must 

 necessarily be subjected to handling entirely dif- 

 ferent from that accorded the ordinary farm or 

 market hog. It is not uncommon for show hogs 

 to contract cholera during contact with other 

 swine in the show ring or in transit from fair to 

 fair, and not infrequently they arrive home appar- 

 ently well, and develop symptoms of the disease 

 during the few days following, thus infecting the 

 entire herd which they represent. This experi- 

 ence has been so common that the practice of 

 showing hogs that are not immune to cholera is 

 indefensible. Some fair associations require cer- 

 tificates to the effect that hogs are immune to chol- 

 era before they will admit them to the show ring. 



The breeder who maintains his herd immune to 

 cholera has no difficulties to face from this quar- 

 ter, for as far as hog cholera is concerned, he may 

 send his animals out on the fair circuit secure in 

 the knowledge that they will not themselves be- 

 come infected, nor be instrumental in infecting 

 others with which they come in contact.
