DAIRY CATTLE AND MILK PRODUCTION 



thoroughbred is properly applied only to the well-known 

 English breed of horses. Pure-bred cattle, as understood in 

 America, are those whose ancestors came from the native 

 home of the breed in question and conformed to the require- 

 ments of this breed here. This blood must be kept pure and 

 unmixed, and records must be available showing the descent 

 from these ancestors. The records of descent of these animals 

 are kept in a systematic manner by associations formed for 

 the purpose by those interested. 



The breeds of cattle common in America are usually classi- 

 fied as dairy, dual-purpose, and beef.
