GENERAL PREVENTIVE MEASURES 



"All that is necessary to prevent hog cholera is to keep 

 the germ of the disease away from the herd. In the 

 vast majority of cases this germ is transported mechan- 

 ically, in the bodies of sick hogs and on the feet of men 

 or animals, including birds. It thus follows that the 

 chances of an outbreak of hog cholera will be greatly 

 lessened, if not completely avoided, if a herd is protected 

 from these carriers of the infection. The enforcement 

 of a complete cjuarantine is not practicable, and the best 

 that can be hoped for is the lessening of the opportunity 

 for infection by placing the herd on a part of the farm 

 that will be the least accessible to men or animals from 

 other farms. Hog lots should never be located near 

 public roads. All newly purchased stock should be kept 

 separate from the main herd for at least thirty days. 



"In addition to protecting by methods of quarantine, 

 careful attention should be given to the general health. 

 The hogs should be provided with clean, dry sleeping 

 places, and the lots and feeding troughs be kept clean. 

 It is well occasionally to scatter slaked lime about the 

 lots and to wash and disinfect the troughs. Probably 

 the best disinfectant for this purpose is the compou'.id 

 solution of cresol (U. S. P.), which can be prepared at 

 any drug store. One part of this should be mixed with 

 30 parts of water and the troughs scrubbed with it. Th.e 

 disinfectant is then washed out of the troughs with water. 



"After an outbreak of cholera the yards and pens 

 should be thoroughly cleaned, all dead hogs should be 

 burned or buried deep with quicklime, the litter should
