FIFTY-FIRST ANNUAL CONVENTION 33 



The bull association goes right along with the cow testing 

 association and I think if I could not have both of them I 

 would take the bull association in preference. 



So if you will see to it that the cows' grandmothers 

 have good records, not extreme, and the great grandmoth- 

 ers have records several generations back, these records 

 when you average them up is about the production you 

 should strive for. 



Then see to it that the bull is strongly bred and is going 

 to transmit these things to his offspring. Keep bulls to pro- 

 duce daughters that will produce the amount of milk and 

 butter fat that is desirable. There is a great law of breed- 

 ing that we call reverting, which means that the calf of the 

 sire may trace back several generations. 



When you do these things and take care of your cows, 

 go ahead and mate them with good sires and raise heifer 

 calves, it will mean gradual improvement generation after 

 generation with a large degree of certainty. 



Thank you very much for your kind attention. (Ap- 

 plause). 



Mr. O'Hair: Friends, there is no use of commenting 

 on what has been said this morning. The day is going to be 

 full. The men who talk to you this afternoon are real dairy- 

 men and you cannot afford to miss hearing them. I am not 

 afraid to say that you folks have the best talent in the 

 United States during this meeting. Now, our time begins
