SWINE DISEASES AND THEIR CONTROL 205 



in the disinfection of houses, sheds, lots, pens, etc., will 

 depend on several factors, chief among which are the 

 organism and the material or places in which it exists. 

 A 1 per cent solution of corrosive sublimate is very effec- 

 tive, but its poisonous nature renders its use more or less 

 undesirable. Chloride of lime is probably the most valu- 

 able, the least poisonous, and least expensive disinfecting 

 agent we have, when used at the rate of five ounces per 

 gallon of water. This is applied by spraying the infected 

 parts or premises. All loose litter and rubbish likely to 

 be infected should be burned. 



In addition to the cleaning up and disinfection of 

 premises proper disposition must be made of the bodies 

 of hogs that have died of disease. These can be either 

 buried or burned. In either case the work should be com- 

 plete. In burying, the top of the carcass should not be 

 nearer than four feet to the top of the ground. A good 

 plan is to sprinkle some chloride of lime over the carcass 

 after placing it in the ground. When the carcasses can 

 be burned it is best. Fat hog carcasses burn fairly easy. 

 A good plan is to place the carcass on a stump and pile 

 brush about it to start the fire. Where brush piles are 

 available hogs can frequently be burned by placing them 

 on top of the pile and firing. Where wood is not plenti- 

 ful a carcass can be burned at little expense and trouble 

 by digging a trench and placing supporting iron bars 

 across, and then by placing the carcass on the bars and 

 burning wood beneath. As soon as the fat starts drip- 

 ping the carcass will usually burn from then on of its 

 own accord. 



In disinfection work and prevention of infection care 

 must always be taken to see that the hogs do not have
