DAIRY MEETING. 99 



Ans. They are liable to get tuberculosis. 



Ques. We understood you to say a moment ago that bovine 

 tuberculosis affected only cattle, while the human germs affected 

 human beings. What danger is there in humans drinking milk 

 from tuberculous cows? 



Ans. They are liable to get bovine tuberculosis. It is the 

 same disease in different animals, that is all. It has been proven 

 beyond doubt that the milk of tuberculous cows may contain 

 the germs and may convey the disease to any other animals that 

 take the milk. 



Ques. How long, in your opinion, would these germs live 

 in a barn? 



Ans, They may live for months in dark sheltered places. 



Ques. If all diseased animals had been either destroyed or 

 quarantined and the barn cleansed as much as possible, after ten 

 months or a year's time would there be any live germs left? 



Ans. If you kill all the germs by disinfection, you can put 

 cattle in at once. If that is not possible the barn should be kept 

 vacant a year at least. 



Geo. a. Smith — We were so unfortunate as to have tuber- 

 culosis in our herd. Dr. Russell said he did not believe the Bang 

 method was practicable for farmers. I would not say it is, but 

 still we carried it through. We had, at the time we tested them, 

 about 30 head of cattle. A little over half of them were diseased. 

 We had quite a good many valuable, full blood animals among 

 them., that we did not feel like sacrificing. We disinfected the 

 "barn thoroughly, and then we washed it thoroughly, and kept 

 our sound animals in that barn. We had another outbuilding 

 that was fairly comfortable, and we put the diseased animals into 

 that building, and as soon as a calf was born it was taken away 

 from the diseased mother and put into the sound herd. The 

 milk of the diseased animals was run through a continuous pas- 

 teurizer at a temperature of 85 degrees, and butter was made 

 from that milk, and the skim-milk was fed to the calves. We 

 used the milk right along and it had no bad effects. This was in 

 1900. Last year, 1905, in the fall, we had grown up a sound 

 herd of as many animals as we started with, and we had been 

 able to preserve that good blood. We had two men, one man 

 who worked in the barn with the sound animals, and another
