TENTH ANNUAL YEAR BOOK-PART VIII 323 



Haecker : I do not think it would. Of course if you fed nothing 

 but silage and fed just previous to milking it might take a little 

 flavor, but we haven't had any trouble that way. If it did Wiscon- 

 sin butter -would be branded as ensilage butter. In Nebraska Ave are 

 going to make a special day, January 20th, as "silo day." Our peo- 

 ple are coming to know that we can not increase our dairy business 

 without a silo. "We must have more winter dairying. Six great 

 centralized creameries make in three months as much butter as they 

 do in the other nine months. We must have the silo in order to en- 

 courage winter dairying. 



President: When I looked out and saw the storm this morning 

 I congratulated myself on the fact that I had thirty acres of com in 

 the silo. There is an advantage that is worth a great deal. 



President : I am sure we have all enjoyed and profited by Prof. 

 Haecker 's talk. We will now hear from Dr. Roberts. He has had 

 several years' experience in the cow business and has been state 

 veterinarian in Wisconsin for a great many yeai's. 



DISEASES OF CATTLE. 



DE. ROBERTS, WISCOXSIX STATE VETERINARIAN, MADISOX, WIS. 



Mr. President and Fellow Dairymen: 



I tliink the subject I was to have is the "Diseases of Cattle" or the 

 importance of healthy stock. Feeling that the stock owners of the United 

 States will be interested at this time in the subject of tuberculosis in 

 cattle it might be wise for me to take up that subject. I want to say that 

 after I talk a short time on this subject I would be pleased to have the 

 subject thoroughly discussed. 



The Government has issued a report stating that tuberculosis is cost- 

 ing the United States something like $14,000,000 a year. They also state 

 that 10 per cent of our dairy cattle are afflicted, 5 per cent of our beef 

 cattle and 2 per cent of our hogs. If this be true it would look as if this 

 $14,000,000 was worth looking into and saved if it is within our power to 

 do it. 



Tuberculosis is a contagious stable disease. It affects the glands of 

 the body, but is liable to affect any part of it. Most people think it is a 

 disease of the lungs only. There isn't a man living that is bright enough 

 to pick the tuberculous cattle out of a herd. For that reason we must 

 "esort to the only test we know of now, known as the tuberculin test. I 

 feel that there are a great many stock owners at the present time that 

 are firm believers in this test and at the same time there are a great 

 many that are not. If it is a proper thing to test our cattle we ought to 

 do it. If not some one ought to show us why. If there were no state 

 laws requiring the use of this test I feel it ought to be applied for your 

 own personal benefit. If you had a herd of 50 cattle and you applied the
