This table shows that, of the bulls having two or more sons 

 tested by their progeny performance test, 25 have increased the 

 butter-fat of their sons' daughters over what the dams of these 

 daughters produced. Fifteen of the sires lowered the butter- 

 fat production of their sons' daughters as compared with the 

 dams of their sons' daughters. 



Of the sires whose sons raised the butter-fat production of 

 their daughters, Glenwood's Combination 8927 proved the best 

 with 142.78 pounds of butter-fat as the mean increase of his 

 sons. A fairly close second to this sire was France's Masher 

 2d 7248. His sons raised the butter-fat of their daughters 

 107.66 pounds over that of the dams of these daughters. For 

 those sires with more than two sons Dolly Dimple's May King 

 of Langwater progeny performance made the best showing. The 

 sons in this case were Ne Plus Ultra, Langwater Dictator and 

 Langwater Demonstrator. Glenwood's Boy of Haddon had 9 

 sons under test. This sire's sons increase the butter-fat of their 

 daughters over that of their dams 52.45 pounds. 



The same caution should be given for the use of this table 

 that was expressed in last year's report. It should always be 

 remembered that this table takes no cognizance of the absolute 

 milk production of the dams; it only concerns itself with the 

 question of whether the dam's record was higher than that of
