Therefore, there is a question, and often heated controversy, as to when or if a breed may need to allow "outside" stock in for the purpose of improving the overall health and vigor of the breed. Because pure-breeding creates a limited gene pool, purebred animal breeds are also susceptible to a wide range of congenital health problems. [3]
Most mating done by purebred breeders is linebreeding which is the mating of animals of different families within the same breed to bring in desirable traits that are not present in the original animals. [11] Unlike commercial producers, purebred breeders cannot use crossbreeding as it would dilute the breed's purity, resulting in a mixed breed ...
Breeding stock is a group of animals used for the purpose of planned breeding. When individuals are looking to breed animals, they look for certain valuable traits in purebred animals, or may intend to use some type of crossbreeding to produce a new type of stock with different, and presumably superior abilities in a given area of endeavor.

In these specific instances, the breeder strives to meet standards in each animal set out by organizations. A breeder may also assist with breeding animals in the zoo.
If the breeding is for a purebred animal that will be used for exhibition or future breeding (pets or livestock), the animal must be registered and conform to the criteria laid out for that breed in a breed standard kept by a central authority, such as a kennel club for dogs. In addition, the breed club, kennel club, or other governing ...

An adult female that has had her first calf (or second calf, depending upon regional usage) is called a cow. Steers and heifers can sometimes be colloquially referred to ...
Purebred dogs have been, for the most part, artificially created from random-bred populations by human selective breeding with the purpose of enhancing desired physical, behavioral, or temperamental characteristics. Dogs that are not purebred are not necessarily a mix of such defined breeds. [61]
