DEPEECIATION OF THE DAIRY HERD 115 



to be able to transmit these good qualities to their 

 offspring. 



Not every dairyman need expect to become a 

 breeder of registered cattle. Indeed, after many 

 years of agitation and propaganda, less than 2 per 

 cent of the dairy cows of the eastern United States 

 are pure-bred. However, every dairyman who ex- 

 pects to rear calves to replenish his herd ought 

 either to own or else pay the service fee of a good 

 pure-bred sire. While a certain rather small per- 

 centage of bull calves of fashionable breeding and 

 bom of dams who have been admitted to "Advanced 

 Registry," that is, dams whose high production has 

 been officially demonstrated and certified, sell at 

 high prices, plenty of calves of excellent breeding, 

 especially when owned by the less widely known 

 breeders, can be purchased at prices quite within 

 the reach of any dairyman.
