DAIRY MEETING. 97 



Alls. No, sir. But we will say this. Bovine tuberculosis is 

 very contagious and cattle that never see the inside of a barn 

 catch it from other cattle. They have a higher percentage of 

 tuberculosis in the Argentine Republic and out in Australia and 

 New Zealand than we have in this country, and the cattle are 

 not housed, and they have an ideal climate. It is a contagious 

 disease for cattle without doubt. They are liable to get it when 

 exposed, but not sure to. 



Ones. Keeping the cattle in the open air, then, is not a 

 preventive, if you have the disease in the herd? 



Ans. The closer you keep the cattle confined with the dis- 

 eased cattle, the more liable they are to be diseased ; but there is 

 danger just as long as sound cattle associate with diseased ones, 

 no matter whether out-of-doors or in a house. The danger is 

 greater the closer the association. 



Ques, How young a calf is liable to get this disease? 



Ans, It may get it the day before, or the day after it is born. 



Ones What is the difiference, if any, between bovine tuber- 

 culosis and human tuberculosis? 



Ans, It is a difference in the species. It is the same disease 

 but affecting different animals. 



Ques, Five years ago I bought a bull calf from out of the 

 State, At that time they gave us a permit to bring him in and 

 it was not necessary to have him tested. Wasn't there danger of 

 his having the disease? 



Ans. Yes, sir. How much danger the members of the cattle 

 commission will tell you today. That permission would not be 

 given you now. You will have to have him tested after getting 

 him home in the future. 



Ones. Speaking of a physical examination to determine 

 tuberculosis, you did not refer to an enlarged joint. Is that an 

 indication ? 



Ans. Yes, an animal that goes lame without any evident 

 cause of injury should be suspected, A soft swelling on the 

 knee is more apt to be produced by friction against the stanchion, 

 but lameness in any joint may be caused by tuberculosis, 



Ques, Suppose a man has a cow suspected to have tuber- 

 culosis. Would it be possible to inject tuberculin before the 

 test so that she will not react?
