Under the heading "grading" are grouped the herds in which 

 some effort has been made to incorporate better dairy blood. In 

 each case the average butter fat per cow is given for the herd in- 

 dicated. The average production per cow in those herds where 

 no concerted action has been taken looking toward improvement 

 is 176.62 pounds of butter fat, while in those herd? where an 

 attempt at improvement has been made, the average production is 

 261.93 pounds. This gives a difference of 85.31 pounds of butter 

 fat in favor of the practice of grading up, which amount at twen- 

 ty-five cents per pound equals $21.32. Reasoning from these 

 results it appears that the productive capacity of the dairy herds 

 of this state may be increased $16,000,000 per year through the 

 use of pure-bred sires and selection by the Babcock test. I doubt 

 if we need better proof of the dire necessity of testing and the 

 use of pure sires in the dairy herds of this commonwealth. The 

 two are inseparable ; they go hand in hand, the test pointing out 

 the cows through which the improvement should be sought ; the 

 use of pure-bred sires intensifying and adding to the dairy ca- 

 pacity of the offspring. 



Dairymen of Illinois, I appeal to your better judgment.
