No. 6. DEPARTMENT OF AGRICULTURE. 129 



Infection will live for a long time outside of the hog's body. 

 J'reniisos that have been oecnpied by infected hogs may be unsafe 

 for other hogs for a number of montlis if the carcasses of the hogs 

 have not been properly disposed of and the premises cleaned and dis- 

 infected. 



It is not necessary for a hog or pig tliat develops hog cholera to 

 have come in direct contact with an animal suffering from the dis- 

 ease. It is easily carried on the shoes, clothes or hands of a person 

 who has been caring for sick animals. It may also be carried by 

 streams, dogs, cats, rats, birds, barnyard fowls, the man who goes 

 from place to place castrating pigs, livestock buyers, the dead animal 

 remover, stock cars, stockyards, stockyard manure, cattle from stock- 

 yards, meat scraps in garbage, etc. 



Since there is no known cure for hog cholera it is important that 

 every precaution be taken to prevent the animals from becoming 

 infected. Various drugs and combinations of drugs have been em- 

 ployed in the treatment of hog cholera and all have failed to cure 

 sick animals or prevent well ones from becoming infected. Various 

 kinds of patent preparations have been f)ut on the market and exten- 

 sively advertised as sure cures or sure preventatives. They have 

 failed to produce the results that their manufacturers claimed for 

 them. 



An animal in good physical condition can resist more infection 

 than an animal in a run down condition. A well balanced ration 

 should be fed. Animals should have plenty of exercise, fresh clean 

 water, shade in the summer, shelter in the winter, well ventilated 

 and dry quarters. The premises should be kept clean. A liberal 

 amount of air-slacked lime should be spread about the pens and 

 hog lots. 



For toning up hogs that are not thrifty the formula developed 

 and tried out by the Federal Bureau of Animal Industry in 1905 

 is suggested: 



Wood charcoal, one pound 



Sulphur, one pound 



Sodium chloride, two pounds 



Sodium bicarbonate, two pounds 



Sodium hyposulphite, two pounds 



Sodium sulphate, one pound 



Antimony sulphide (black antimony), one pound 



Pulverize each ingredient and mix thoroughly. The dose is a large 

 tablespoonful for each 100 pound weight of hogs to be treated. It 

 fehoukl be given in the feed once a day. 



Newly purchased animals, boars standing for public service, sows 

 that have been away to be bred and animals returning from the shows 

 should be kept in quarantine on an isolated portion of the premises 

 for three weeks. If they are not showing signs of illness up to that 

 time they should be given a thorough scrubbing in a 2% Cresol 

 Compound (U. S. P.) or 2% creolin solution (about two and one-half 

 ounces of either to the gallon of water) and then placed in their 

 permanent quarters. A hog owner should not visit premises where 

 hogs are known to be sick, neither should he permit strangers in his 

 hog pens or lots. Pens and lots should be so located that they do
