374 Missouri Agricultural Report. 



complete milk and butter-fat records have been kept of every cow. 

 Up until 1901 practically every female was retained in the herd 

 regardless of her dairy qualities. These conditions give an oppor- 

 tunity to study the effect of sires which can hardly be duplicated 

 anywhere. 



The first bull used was Missouri Rioter, 19400, a son of Bachelor 

 of St. Lambert. There is no record indicating the dairy quality 

 of his dam. In fact, his sire is the only animal in his pedigree 

 known to be a strong breeder. This bull was a very weak breeder,

as is shown in the chart. His daughters averaged 4,336 pounds 

 of milk per year while their dams averaged 5,380 pounds. A de- 

 cline on the average of 1,044 pounds of milk per year each. The 

 average yearly fat production of the dam was 234 pounds, while 

 the daughters averaged only 216 pounds. A decline of 18 pounds 

 per cow annually from the dams to the daughters. 



The income from ten daughters, counting milk at six cents per 

 quart, fell $313.20 per year behind the dams. Counting fat at 25 

 cents, the loss was $45.00. As long as this- bull remained in the 

 herd, it was going backward in production, instead of ahead. Sup- 

 pose the herd had had thirty daughters of such a bull. Each year 

 we would have been $135.00 behind what the dams produced, count- 

 ing fat at 25 cents. If these cows were milked six years each, the 

 total loss would be $820.00. This sum would buy several good bulls.
