156 DAIRY CATTLE AND MILK PRODUCTION 



hand at the time this compilation was made (1910) was de- 

 scended from these cows. Herd bulls were of course pur- 

 chased from other herds, but no females. Since 1892 com- 

 plete milk and fat records have been kept of every cow. Up 

 to 1901 practically every female was retained in the herd, 

 regardless of her dairy qualities. While the conditions under 

 which the herd was kept were not entirely uniform, still no 

 more variation occurred than would be the case in a private 

 herd. A comparison is made of the records of the daughters 

 of each bull, compared with the production of their dams. 

 In most cases the figures given represent the whole lifetime 

 of both. In case only a limited number of records are avail- 

 able, these are compared with the corresponding ones of the 

 dam. When a lactation period extends beyond a year, only 

 the first twelve months' record is used. The low average 

 production is accounted for by the fact stated that for the 

 greater part of the time all females were retained, and by the 

 records of inferior cows sold while young. 



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

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

 quality of his dam. His sire is the only animal in his pedigree 

 known to be a strong breeder. This bull left four daughters 

 in the herd that have a total of 26 lactation periods, from 

 dams with 23 periods on record. Below is given a summary 

 of the records of these daughters and their dams.
