SELECTION AND IMPROVEMENT OF DAIRY CATTLE 73 



M any interesting comparisons may be made of the com- 

 pare tive values of these bulls. For example, the daughters 

 of Lome of Meridale averaged 1491 pounds of milk more 

 per year for their entire lifetime than did their dams. Eleven 

 out of thirteen were superior to their dams. If thirty 

 daughters of this bull had been milked in one herd, their 

 pro- luction would have exceeded that of their dams by 44,730 

 pounds per year. At $1.50 per 100 pounds the income would 

 be s671 per year more for the thirty daughters than for their 

 mo 1 hers. If the animals were daughters of Missouri Rioter, 

 the 7 would have produced 999 pounds each less than their 

 dams or a total of 29,970 pounds less milk than their mothers 

 in i\ year. At $1.50 per 100 pounds this would be a decrease 

 of S450. It would then make a difference of $1121 per year 

 whother these thirty cows be daughters of Missouri Rioter 

 or Lome of Meridale. If we make the comparison directly 

 from the average yield of the daughters, the difference would 

 be 50,070 pounds of milk per year worth $751 at $1.50 per 

 100 pounds. If the greatest extremes be taken for compar- 

 ison, as Missouri Rioter 3d and Missouri Rioter, the dif- 

 ference is far greater. 



56. Methods of Selecting a Bull. There are two ways of 

 selecting a bull : 



1. On the basis of his pedigree and appearance. 



2. From the records of his daughters. 



The pedigree is the most reliable means of judging the 

 probable value of a young bull. The system of advanced 

 registration now in use makes it possible to obtain reliable 

 information concerning the dairy qualities of most of the 

 registered animals. In selecting a young bull one should 

 have these records before him. The points to be considered 

 are especially the records of the cows that are the close an-
