摘要

Scientific debates show that it is difficult to define exactly what is a domesticated species. Nevertheless, any regulation must clearly determine the scope of its application. In France, regulations on Nature conservation include protection of non-domestic species because it is assumed that captive breeding can have an impact on their conservation. On the other hand, domesticated species or varieties are kept in captivity without being supposed to disturb the natural balance of wild species. Accordingly, it is essential to be able, for instance in breeding control, to assert whether or not the animals are domesticated. Species which have not suffered modifications induced by artificial selection are considered non-domesticated. Animals in this category are supposed to belong to non-domesticated species. It follows that domesticated species have been selected continuously for a long time by Man and have acquired stable, heritable traits. Even if an animal belonging to a wild species is born and kept in captivity for a long period, this has no bearing on its status as a non-domesticated animal. Nevertheless, it is acknowledged that the species is not the only taxonomic entity that allows domesticated and non-domesticated populations to be distinguished: breeds and varieties must also be considered and, in some wild species, the existence of domesticated breeds or varieties has been recognized. They have been listed in 1994. It is not always easy to put into effect these regulations, especially when they concern wild bird species that include domesticated breeds or varieties. It is therefore necessary to act with caution and flexibility. Taking the phenotype into account is not always sufficient. For instance, it may happen that a mutated coloration, considered as characteristic of a domesticated variety, masks a recent crossing with wild birds taken in nature. In that case, the animals concerned should have the same status as hybrids and are subject to nature protection regulations. Caution is needed in appreciating the homogeneity of a flock, when only a few individuals are observed. When a mixture of wild and domesticated phenotypes is observed, the whole flock must be considered as composed of non-domesticated animals. It is also necessary to take into account the interests of breeders and to protect wild species. A satisfactory compromise seems to have been proposed.
