No. 6. DEPARTMENT OF AGRICULTURE. Ill 



who will be warned to keep away. Tt requires the owner to keep his 

 hogs condned and ])rohibits him from selling or otherwise disposing 

 of hogs or pigs while the quarantine remains in force, unless permis- 

 sion is granted in writing by the Board. The owner is expected to 

 observe every possible precaution to prevent the spread of the dis- 

 ease. All manure, litter, etc., removed from the hog pens and hog 

 lots must be burned or mixed with lime and spread on an isolated 

 field where it will be plowed under as soon as possible. 



The law requires that the carcass of any animal that dies of a 

 transmissible disease must be buried, cremated or boiled. If cre- 

 mated the entire carcass with all its parts and products must be re- 

 duced to ashes. If boiled it must be "kept boiling continuously for 

 at least two hours. If it is not practicable to either cremate or boil 

 the carcass, it and its parts and^ products may be buried in a place 

 that shall not be subjected to overflow from ponds or streams, and 

 v/hich shall be distant not less than one hundred feet from any 

 watercourse, well, spring, public highway, house or stable. Car- 

 casses must be covered with quicklime to a depth of not less than 

 three inches, and the uppermost part of such carcasses shall not be 

 within two feet of the surface of the ground when the grave is filled 

 and smoothed to the level of the surrounding surface. The grave 

 must be so protected that the carcass will not be accessible to dogs, 

 or other animals. 



Disinfectants such as carbolic acid, bichloride of mercury, etc., 

 have not proven satisfactory in destroying hog cholera virus in hog 

 pens and lots. A thorough cleaning and disinfecting of hog prem- 

 ises can best be accomplished by scraping the walls and floors. The 

 material gathered, together with all manure and litter from the hog 

 pens, should be burned or thoroughly mixed with lime and hauled 

 to an isolated field where it Avill be plowed under as soon as possible." 

 If the floors are old boards they should be taken out and burned. 

 The earth under the boards should be taken off for several inches 

 and treated the same as the manure and litter. If the floors are of 

 earth only, several inches should be taken ofl'. mixed with lime and 

 turned under. The ceiling, walls and floors should then be saturated 

 with a solution of Cresol compound (U. S. P. Liquor Cresolis Com- 

 positus) four ounces to the gallon of Avater. After this has dried 

 the pens should be whitewashed with a solution of whitewash to 

 which has been added chloride of lime in the proportion of one 

 pound to three gallons. Air slacked lime should be thickly spread 

 over the floor and ground. 



The wagon and utensils used in hauling hogs that have died with 

 cholera and spreading the manure, litter, etc., should be disinfected 

 by repeated washings with a solution of cresol compound of the 

 strength recommended above. 



In 90 per cent, of the instances where a number of hogs or pigs 

 become ill and several die the losses may rightly be attributed to 

 hog cholera. 



It is very important that outbreaks of hog cholera be reported 

 without delay, because the best results from the use of hog cholera 

 serum can only be obtained when it is used u|)on animals that are 

 not showing the recognized symptoms of the disease. 



It is easy to understand Avhy hogs should be vaccinated as soon as 

 possible because the serum protects against the virus of hog cholera
