 TUBERCULOSIS 



No treatise on the subject of dairying is com- 

 plete unless some mention is made of tubercu- 

 losis, that dreaded disease which has already 

 carried off thousands of cattle, and whose rav- 

 ages continue almost unabated. 



Tuberculosis the dangerous scourge. It is said 

 that one out of every seven people who die fall 

 victims of tuberculosis, or consumption, as it is 

 commonly called. It is now pretty generally 

 believed that tuberculosis in cattle and consump- 

 tion in the human family are practically one and 

 the same disease, and that this disease can be 

 transmitted from one species to the other. Young 

 children fed on the milk of tuberculous cows 

 are likely to contract the disease, and calves 

 and pigs consuming infected milk are almost 

 certain to be affected. 



How tuberculosis spreads. Tuberculosis is a 

 germ disease; that is, it is caused by the growth 

 and multiplication of very minute organisms 

 within the animal body. The disease cannot be 

 contracted without the entrance of these germs.
