CHAPTER VI. 



TUBERCULOSIS. 



The rapid awakening of the public to the 

 danger from using the milk of tuberculous cows, 

 with the senseless and in some cases frenzied 

 antagonism of dairymen to the tuberculin test, 

 causes me to give my experience covering 

 twelve years with the tuberculin test for de- 

 tecting tuberculosis in cows. 



Experience with Tuberculosis. — My experi- 

 ence commenced in 1895 when I embarked in 

 the certified milk business. Mine was the first 

 large dairy in the state to have the tuberculin 

 test applied to it. I had little information to 

 help me to judge how large a percentage of 

 tuberculous cows I should find and it required 

 considerable nerve to undertake the work, 

 knowing that all tuberculous animals would be 

 a total loss to me. I was so fortunate as to find 

 that only three per cent of the 133 cows tested 

 reacted. One of the reacting cows was the cow 

 from which the family was using milk. This 

 cow was in good beef condition, but we found a 

 tuberculous ulcer in one lung as large as a pint 

 cup.
