lost or injured, particularly if the weather is cold. Such 

 losses may often be prevented by providing each sow with a 

 brood house and dry bedding, and by seeing that the weak 

 pigs are kept warm and receive proper nourishment. 



One of the chief losses in hog raising is caused by hog 

 cholera, which is responsible for 90 per cent of all the losses 

 by disease. The total yearly loss for the entire country is 

 estimated at $30,000,000. 



The danger of hog cholera and other diseases may be 

 greatly reduced by providing the animals with clean water 

 and clean, well- ventilated, frequently-disinfected quarters. 

 If cholera appears, all healthy animals should be removed 

 to clean freshly-disinfected quarters, and the old quarters 

 should be thoroughly cleaned and disinfected; the bedding 

 and all loose material likely to bear infection should be burned. 

 The dead animals should be burned or destroyed by means 

 of quick lime, and all places likely to be infected should be 

 treated with fresh lime or some other good disinfectant. 



Vaccination seems to be a good insurance against hog 

 cholera, but it is not likely to be effective if hogs are kept 

 under unsanitary conditions.
