Historians have established that cattle were on this planet 7,000 years ago. Breeds of cattle have been identified for several hundred years. A breed is defined as "a relatively homogenous group of animals within a species, developed and maintained by man". In 1920 the average college textbook in the U.S. listed 16 beef cattle breeds compared with 21 breeds listed in the 1969 college textbooks. In 1975 the up-to-date college textbook could list 68 cattle breeds. This is the number identified by the National Association of Animal Breeders.
