Breeding stock

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

birds, as well as less common animals, such as reptiles or some primates
.

Purebred breeding

Mating animals of the same breed for maintaining such breed is referred to as purebred breeding. Opposite to the practice of mating animals of different breeds, purebred breeding aims to establish and maintain stable traits, that animals will pass to the next generation. By "breeding the best to the best", employing a certain degree of inbreeding, considerable culling, and selection for "superior" qualities, one could develop a bloodline or "breed" superior in certain respects to the original base stock.

Such animals can be recorded with a

. The observable phenomenon of
hybrid vigor
stands in contrast to the notion of breed purity.

For laboratory purposes, organisms such as mice have been inbred to 100% pure lines, as offered for sale by the Jackson laboratory. But this is highly unusual and difficult to do for most organisms, in whose populations all individuals harbor recessive, deleterious gene variants (alleles).

Backyard breeding

In the United States, a backyard breeder is someone who breeds animals, often without registration and with a focus on profit. In some cases, the animals are inbred narrowly for looks, with little regard to health.
