416 Effective Farming 



infected readily. They should be exposed as far as possible to sun- 

 light, which is the cheapest and one of the best disinfectants. Hog 

 lots should not be used for yarding wagons and farm implements 

 and should not be entered with team and wagon, particularly when 

 loading stock for shipment to market and when returning from stock- 

 yards and public highways. No one should be allowed to enter hog 

 lots unless there is assurance that he does not carry infection. Farm- 

 ers and their help should disinfect their shoes before entering hog 

 lots after returning from public yards, sales, and neighboring farms. 



Wallow holes and cesspools should be drained, filled in, or fenced 

 off. 



Runs underneath buildings should be cleaned and disinfected and 

 then boarded up. Straw stacks that have been frequented by sick 

 hogs should be burned or removed to the field and plowed under. In 

 fact, it is a dangerous practice to leave remnants of stacks from year 

 to year, and new tenants should beware of this source of danger. 



Hogs that do not recover fully from cholera should be destroyed, 

 as they remain constantly dangerous. 



All animals that die on the farm, as well as the entrails removed 

 from animals at butchering time, should be properly disposed of by 

 burning to ashes, or by burying with quicklime away from streams 

 and low places. Unless disposed of in this way they will serve to 

 attract buzzards, crows, and dogs that may bring or carry away the 

 germs of hog cholera. 



Newly purchased stock, stock borrowed or loaned for breeding pur- 

 poses, and stock exhibited at public fairs should be placed in isolated 

 pens and kept there for at least fifteen days before being turned in 

 with the herd. During this quarantine care should be used to prevent 

 carrying infection from these to other pens by those who feed or care 

 for stock. 



Hogs should not be allowed to follow newly purchased stock unless 

 such stock has been dipped or driven through a suitable disinfectant. 



If hog cholera appears on the farm a notice should be posted at 

 the entrance to the premises reading "HOG CHOLERA KEEP 

 OUT," and all neighbors should be warned so that they may protect 

 their herds. The infected herd should be confined to limited quarters 

 that can be cleaned daily during the presence of the disease and sprayed 

 occasionally with a disinfectant consisting of one part of compound 

 cresol solution to thirty parts of water, or with a recognized substitute 

 therefor. 



Up to the present time no drug or combination of drugs is known 

 which can be regarded as a preventive or cure for hog cholera in a
