Hog Cholera. 15 



the most filthy part of the yard. The wallow should be artificially 

 made of planks or cement and kept well filled with clean water 

 containing a disinfectant of creolin — one ounce to one gallon of wa- 

 ter. This should be cleaned outside of the yard and refilled about 

 every ten days. 



Streams draining from lots higher up should not be allowed to 

 run through the yards. Feed troughs and floors should be kept 

 free from stale food, corn-cobs and wet litter. 



There is no place on the farm where disinfectants are as neces- 

 sary as in the hog houses and yards. Carbolic acid — one tablespoon- 

 ful to two gallons of water, or creolin — two tablespoonfuls to one 

 gallon of water make excellent disinfectants. Whitewash con- 

 taming sulphur and creolin in any proportion desirable, used on 

 the inside of the pen makes one of the best disinfectants. 



Hogs newly bought or coming from other herds should be kept 

 entirely seperate from the home herd for at least three weeks. 

 During this time they should have a different care-taker and sepa- 

 rate utensils should be used for feeding and caring for the animals. 



The question is often asked by farmers, "How long before new 

 hogs can be safely put into pens that have been infected?" 



New hogs should not be put on the same farm for at least three 

 months and not in the old pens for one year. New pens and yards 

 should be provided at least one hundred yards from the old pens. 



The old yards should be limed, plowed and planted and the old 

 pens should be burned or whitewashed and disinfected as describ- 

 ed above. 



Each hog should be thoroughly sprinkled, using a garden water- 

 ing-pot of disinfectant, composed of two tablespoonfuls creolin to 

 one gallon of water. 



The second essential in keeping hogs free from cholera is vacci- 

 nation with cholera serum before they become exposed to the dis- 

 ease. 



The method of vaccinating hogs for hog cholera should be un- 

 derstood and carried out by the farmer or hog raiser just as the 

 farmer vaccinates his calves for black leg. The object of vaccina- 

 ting and the methods used are just the same, except in black leg the 

 new and up-to-date method is to use a pill, where in hog cholera a 

 certain quantity of serum is used for every pound of hog flesh. 

 The farmer can estimate the weight of his hogs and give the meas- 

 ured amount of serum just as well and as efficiently as the veteri- 

 narian, as long as he follows out the directions laid down in this 

 bulletin.
