 known and a comparison may be made of the individuals re- 

 peated in the superior sires pedigree with those repeated in the 

 inferior sires pedigree. 



Before beginning this study it was decided that any indi- 

 vidual which was not repeated at least once in the pedigrees of 

 a given group of sires could not have contributed any notice- 

 able amount to making the group as a whole worthy or un- 

 worthy. Accordingly the study will confine itself to those 

 animals that were repeated at least once. 



Table 12 gives the animals repeated in the pedigrees of 

 the sires which increased the milk production and butter-fat 

 percentage of their daughter over that of their dams.
