290 SWINE PRACTICE 



mals and rendering them more susceptible to disease. Swine that are 

 given the proper diet are not necessarily immune to cholera, but they 

 are much more resistant than swine affected with digestive derange- 

 ments. Swine should also receive an abundance of clean, wholesome 

 water, and not be permitted to drink water from polluted streams or 

 stagnant; pools. Many cases of what would probably have been fatal 

 cases of cholera have been nursed back to health by providing good 

 surroundings and a diet of clean, sweet milk. 



Carcasses of swine, regardless of the cause of death, should be 

 promptly disposed of, preferably by burning. To permit carcasses to 

 putrefy in lots or other places, invites carrion birds and animals such 

 as crows, buzzards, dogs, cats, wolves, foxes, rats, etc., and the dis- 

 semination by infection by such means may cause serious losses to 

 neighbors or on remote farms. Barnyard fowls and pigeons are fre- 

 quently the means of spreading infection from farm to farm. 



Every well regulated farm has provision for isolation of new stock, 

 such as boars, brood sows, or stocker hogs. It is also advisable to quar- 

 antine all swine that have been used for exhibition purposes at state 

 fairs or stock shows. The period of quarantine should never be less than 

 three weeks. By this measure many general outbreaks of hog cholera 

 and other infective diseases of swine can be prevented. Whenever 

 disease appears on a farm it should be rigidly quarantined to prevent 

 the spread of infection to adjacent farms. Police regul§J;ijQDSi and 

 general sanitary measures should be instituted or more rigidly en- 

 forced if they have been provided for by the various live stock sanitary 

 boards. The following rules and regulations have been recommended 

 and if enforced will be an important factor in diminishing the losses 

 incidental to hog cholera. 



1. The shipment or movement, interstate, of swine affected with 

 cholera to be prohibited. 



2. Exposed swine to be shipped under permit and placard. 



3. The' raovement of cholera-infected swine over the public high- 

 ways to be prohibited. 



4. Provision for moving exposed swine under permit in approved 

 manner. 



5. Carcasses of animals, and particularly of swine that have died 

 of cholera, to be burned within twenty-four hours after death, or 

 Tinder special permit to be disposed of otherwise. 



■ ■ 6. The shipment by rail of swine for purposes other than imme- 

 diate slaughter to be permitted only through special pens and unload-
