TENTH ANNUAL YEAR BOOK— PART VIII 327 



Dr. Roberts: No,' The winter months arc the best. When cat- 

 tle are in their natural condition is the proper time to test. The 

 winter months are the best, especially in the fall. 



Member : Will a healthy cow be liable to get tuberculosis from 

 other cattle by being in the same pasture? 



Dr. Roberts : They are not very apt to, but I would not premit a 

 healthy animal and an infected animal to be in the same pasture. 

 There is danger in permitting both to run together. 



When tuberculin first came out the directions stated that if the 

 temperature raised one and a half degrees the second day over the 

 temperature of the first day it would indicate tuberculosis. Later 

 on the directions came out stating two degree raise. I believe that if 

 an animal has tuberculosis its temperature will go up to 104 to 107.2. 

 You really don 't have to guess at it. 



Hogs contract tuberculosis rapidly. Hogs and calves receiving 

 milk from creameries where the milk has not been pasteurized con- 

 tract the disease very rapidly. 



Member: The question has been asked several times how early 

 or how young an animal can be tested? 



Dr. Roberts : You can test a calf at a month old. Three months 

 is old enough to test calves. 



Member: Is it not well to sound a Avarning not to sell reacting 

 cattle to stock buyers ? I have known where animals have been con- 

 demned and sold for $10 or $12 and passed by the federal inspector. 

 There has been more or less graft and I do not believe there is any 

 need of standing for it. 



Dr. Roberts: I will say that I feel that a man owes it to his 

 fellow men when he finds, a tuberculous animal to kill it. Cattle 

 have been tested, reacted and shipped to Chicago and sold for dairy 

 cattle. The}' are shipped back and put in a clear herd and soon the 

 whole herd would be rotten with tuberculosis. Wisconsin reim- 

 burses her farmers to the amount of four-fifths of the assessed 

 value. I would not consider it wise for the Iowa farmer to wait 

 until you pass a law. It is much better to prevent the disease than 

 it is to be recompensed for condemned animals. Separate the in- 

 fected cow from the herd and you can save the balance. I believe 

 tills question is holding back the live stock industry. I know lots 

 of people who would go into the question of dairy-bred cattle if it 

 were not for tuberculosis. I want to present both sides and let the
