Register of breeding

In the field of the maintenance and breeding of the animals, a register of breeding so known under the anglophone name of studbook , of animals belonging to some Espèce is an official list, under species or line, and whose parents are known. The animals are generally recorded by their stockbreeder when they are still young.

Animals concerned

Pets

There are registers of breeding for many species of animals, such as for example the dogs, the cats or the horses. These studbook is mainly used for preserving pure lines or to select particular features.

Wild animals

EAZA maintains also studbooks to follow the shown captive wild species to the public. These studbooks is used mainly for to preserve in captivity of the disappeared species or in the process of disappearance.

Types of studbooks

Closed

In a studbook closed , the parents must also be recorded in the same register or another recognized register. That guaranteed that the individual is of pure line. The animals accepted by the studbook before its closing are known like the livestock of foundation. Then all the animals resulting from this studbook closed are downward livestock of foundation.

Opened

In an open studbook the animals can be recorded without their parents being them even recorded in a studbook. This makes it possible to the stockbreeders to reinforce certain lines, by adding individuals selected for certain characteristics of external appearance (dress, appearance, strength). A studbook of the open type is thus not adapted to the conservation of species in the process of disappearance.
