SUMMARY 299 



Never purchase hogs from an infected pubhc stock-yard and take 

 them home to place in your own feed lots. Also, never allow 

 hogs being shipped in by you for feeding -or breeding purposes 

 to be unloaded in a pubUc stock-yard pen for feeding and water- 

 ing. To do so means infection in a large percentage of cases. 



Do not overlook the fact that hog-cholera infection can be car- 

 ried from an infected stock-yard pen to your own feed lots by 

 other animals as well as hogs. Cattle and sheep are also capable of 

 scattering the infectious material from one part of the country to 

 another by carrying infectious manure, litter, and mud upon their 

 hoofs. 



Insist on a thorough disinfection of all public stock-yards, or 

 at least the keeping separate of free and quarantine pens. Thor- 

 ough disinfection should follow the passage of any shipment of 

 hogs through these pens, and especially so if they are cholera- 

 infected or exposed herds. Proper provision should be made for 

 this by Act of the State General Assemblies, and it is your duty as a 

 tax-payer to see that your legislators give attention to this point 

 of protection upon the part of the railroads and other common 

 carriers. 



(11) Infected Stock Cars. — We have found that a herd of 

 cholera-infected animals are capable of infecting the lots in which 

 they are kept, and also that they are capable of leaving enough 

 disease-producing material in the railroad cars in which they are 

 shipped to cause an outbreak of cholera in the next herd of hogs 

 that is loaded into these cars for shipment. To avoid disease 

 you must insist when you are shipping hogs to your feed lots for 

 feeding or breeding purposes that the cars in which they are loaded 

 be free from disease germs. 



This can only be assured by a thorough cleaning and disin- 

 fection of the cars after each time they are used for the shipment of 

 swine. When you are making shipments of this kind absolutely 

 insist that you receive a car which has been properly cleaned and 

 disinfected, if possible, under supervision of a United States Bureau 

 of Animal Industry official. 



Remember that the danger from these cholera-infected cars 

 is not by any means limited to the shipment of hogs in them, but 

 also applies to the shipment of any other class of animals, such
