and faithfully abides by those measures, eradication will 

 be accomplished more speedily. 



From what has been said already about the dangers of 

 shipping diseased cattle, it is plain that the movement of 

 tuberculous cattle, except for immediate slaughter or to 

 quarantine, must be stopped whenever possible. After dis- 

 eased animals are found and removed from the premises, a 

 very thorough cleaning and washing of the inside of the 

 barn and other buildings where the animals have been 

 should be made. This must be followed by the proper ap- 

 plication of some approved disinfectant. The use of disin- 

 fectants without first doing the necessary and proper clean- 

 ing is ineffective for the reason that the germs of the disease 

 must be exposed. All utensils or anything else that may 

 have become contaminated by use around the diseased ani- 

 mals should likewise be cleaned and disinfected. The 

 manure and refuse must be hauled from barnyards or lots 

 to plowed fields, spread thin, and exposed to the sunlight. 

 The yards and lots, including feed troughs, water troughs, 

 and fences can then be sprayed properly with the disin- 

 fectant. 



All this means much work but it must be done to pre- 

 vent infection from spreading to the healthy animals. 

 Proper sanitary conditions on premises where live stock are 

 kept is of great importance in keeping the animals healthy 

 and able to resist disease. Sanitation, in its broad sense, 

 includes the admission of abundant sunlight and fresh air 

 properly regulated. 



Disposal of Reactors. 



The disposal of reactors depends largely upon the 

 State laws and live-stock regulations of the State in which 

 the herd belongs. If the animals are pure bred and regis- 

 tered and of unusual merit, they should be segregated, pref- 

 erably on farms set aside by the State or by the pure-bred 

 cattle associations, for the purpose of retaining tuberculous 

 cattle in quarantine. If the condemned animals are grade 

 cattle, or pure breds not specially valuable for breeding, it 

 will probably be more economical to have them slaughtered
