SELECTION OF THE HERD BULL 157 



The average production of the daughters was 1009 pounds 

 of milk and 18 pounds of fat per year below that of their dams. 

 In every case the daughter was inferior to the dam. While 

 the number of daughters is too few to make the data con- 

 clusive, it is certain this bull did not transmit the qualities 

 wanted. The same results in a herd having thirty of his 

 daughters would mean over 30,000 pounds of milk and 540 

 pounds of fat per year less than the dams. If each daugh- 

 ter was milked six years, it would mean over 6000 pounds 

 of milk less for each during her lifetime than her dam. pro- 

 duced. In other words, it would take over six years for the 

 daughters to produce as much as the dams would in five 

 years. 



The next bull was Hugorotus, a cheap bull without any 

 high-class animals in his pedigree. This bull had eleven 

 daughters, with a total of 50 lactation periods from dams 

 with 62 lactation periods on record. The comparison below 

 shows the results. 



The eleven daughters average 393 pounds of milk below 

 their dams, but on account of a marked increase in the rich- 

 ness of the milk, gain 14 pounds in fat per year. Six out of the 

 eleven daughters were decidedly inferior to their dams. The 

 general results of using this bull were disastrous. In fact, 

 the poorest animals ever in the herd were his offspring. 

 The averages are made as good as they are only by two full
