98 AGRICULTURE OF MAINE. 



Ans. Yes, sir, so that she may not react. The first test is 

 more rehable. 



Ques. Are there any leading indications of tuberculosis? 



Ans. If you have but one animal it is pretty hard to detect 

 it unless she is in an advanced stage. If you have a large herd 

 and you know you have the disease in the herd, you can some- 

 times make up your mind that other animals have it, with very 

 slight indications. 



Ques. You cannot go into a herd and stand there a few 

 minutes and observe them and determine whether or not thev 

 have tuberculosis? 



Ans. No, unfortunately not, or you would not have to apply 

 the tuberculin test. 



Ques. What are the leading symptoms? 



Ans. Unthriftiness, coughing, enlarged glands and lameness 

 are indications of the disease ; but the majority of animals that 

 have tuberculosis do not show any of these symptoms. 



Ques. You would not suspect a cow with a good, thrifty coat 

 and appearance, lively in every way, would you? 



Ans. Unfortunately every animal is suspected until it is 

 proved sound. We suspect every animal of having tuberculosis 

 until she has a clean bill of health. The only safety is to have 

 them tested. 



Ques. HPow much of a rise in temperature do you consider 

 a reaction? 



Ans. That depends somewhat on the initial temperature. We 

 do not ordinarily reject an animal unless the maximum tempera- 

 ture is over 104. A calf six months old may sometimes have a 

 temperature of 104, and not be rejected. 



Ques. If the initial temperature was 102 and there was a 

 rise of two degrees, would you call it a reaction? 



Ans. If 102 was a normal temperature, and we could not 

 account for the rise in any other way, we should be obliged to sav 

 that the cow had tuberculosis. 



Ques. What is the danger of infection from the use of milk? 



Ans. The milk may convey the disease to other animals. 

 There is no safety in using it uncooked. 



Ques. What is the danger to human beings from drinking 

 the milk?
