192 high producing daughters 548.10 



Dams of low producing daughters 473.50 



Dams of high producing daughters 500.37 



The influence of the dam on fat-production is evident. Compiling 

 the data in another way, we have : 



Pounds 



192 low producing dams 428.07 



192 high producing dams 546.22 



Daughters of low producing dams 482.86 



Daughters of high prodvicing dams 500.61 



While there is a difference of ii8 pounds of fat between the high and 

 low producing dams, there is a difference of only i8 povtnds between the 

 daughters. This indicates that the sire also has something to do with the 

 inheritance of dairy quality. 



By dividing the dams into two groups, regardless of the bull to which 

 they were bred, placing in one group all cows producing 500 lbs. or more and 

 in the other all producing under 500 pounds, we have the following : 



Xumber of danis jaroducing 50(1 poiuids or more 132 



N'umber of dams jjroducing less than 300 jjounds 252 



Lbs. fat 



Average of high producing dams 599-05 



Average of low producing dams 428.53 



Average of daughters of high producing dams 532.87 



Average of daughters of low jiroducing dams 470.18 



All the methods of comparison strongh^ indicate that fat-producing 

 ability is inherited from the dam as well as from the sire, and that the prac- 

 tice of retaining heifer calves from the best cows for replenishing and buid- 

 ing up the herd is sound. The fact, sometimes observed, that with 

 poorer quality cows and selected bulls high producing daughters have been 

 obtained, must be chiefly- considered as an exception which should not be 

 made the basis in the selection of dairy cows for increased milk prodtiction.

On the 1st January 1916 the cows in each breed yielding the highest 

 semi-official yearly records in the United States, as communicated by the 

 Secretariates of the several breeding associations, were as follows :
