118 Missouri Agricultural Report. 



Garrett of Maryville, a prominent breeder of Poland-China hogs, 

 has told me that he has been able to bring in new animals within 

 a very few weeks after he had had the disease on his place, by the 

 liberal use of quick-lime in disinfecting the grounds. But he said, 

 "I did a thorough job of it." It is well in an outbreak of this dis- 

 ease to separate the apparently healthy hogs from those that are 

 diseased ; and to divide the healthy lots into several smaller bunches 

 and place them in separate pens on clean grounds. In this way if 

 only a few of the number are infected the opportunities for a gen- 

 eral spread of the disease is lessened. The dipping of the hogs, 

 that have been exposed, in any of the carbolic dips which are in 

 general use, is another measure which will aid in preventing the 

 spread of the disease. 



The spread of hog cholera is greatly augumented by the neg- 

 lect of the swine owner to burn the carcasses of animals that die 

 of this disease. Many a wide spread outbreak could have been 

 prevented had the proper measures been employed. In the fall of 

 the year it often happens that a farmer who has raised a good corn 

 crop and does not have a sufficient number of hogs to dispose of 

 it, buys a carload of hogs in some distant part of the State. The 

 exposure of these hogs to infection in the local stock yards of the 

 region where they are bought, often starts the disease in the lot 

 within a few weeks. The farmer ascribes the disease to the feed- 

 ing of new corn, or to other causes than the real one. The hogs 

 lie around unburned and the infection is distributed to neighbor- 

 ing farms, by the drainage to lower lying places, by dogs and birds 

 carrying diseased parts away, and in other ways. 



We have laws in regard to hog cholera and other contagious 

 diseases which provide that animals dying from a contagious dis- 

 ease shall be burned or buried, and that notice shall be given the 

 neighbors in regard to the presence of the disease on the farm. It 

 is also a misdemeanor to permit these sick animals to run on pub- 

 lic roadways or the commons. These laws, however, are not known 

 to many farmers, or their importance is not appreciated, since it 

 is too common an occurrence to find during an outbreak of this 

 disease, hogs lying rotting in the streams that run through the in- 

 fected farm. 



In regard to medicinal treatment, I know of nothing better 

 than that recommended in the Farmers' Bulletin No. 24, issued by 

 the United States Bureau of Animal Industry. The various pro- 

 prietory remedies that are on the market are made up of practically 

 the same ingredients.
