Summary

Poultry biodiversity conservation is a great challenge for many countries. Within the last several years, the number of endangered local breeds has increased, leading to a considerable loss of genetic resources. A similar trend was observed among the poultry breeds, including chicken, local turkey and goose breeds/lines established in Bulgaria, part of which is definitely lost. Currently these breeds/lines are at risk and/or threatened with extinction. The information obtained by phenotypic characterization of these breeds is the first step for planning the management of poultry genetic resources through setting up improved selection schemes and conservation strategies. In this paper, we reviewed the current state of knowledge regarding the morphological and phenotypic diversity of local poultry breeds and some old productive poultry lines in Bulgaria.

La conservation de la biodiversité avicole s'avère un grand défi pour beaucoup de pays. Au cours des dernières années le nombre de races locales menacées a augmenté, ce qui a entraîné une perte considérable de ressources génétiques. Une tendance similaire a été observée parmi les races de volailles (races et lignées locales de poules, dindons et oies) établies en Bulgarie, dont certaines ont été perdues à jamais. De nos jours ces races ou lignées sont menacées et/ou en voie de disparition. Obtenir de l'information par le biais de la caractérisation phénotypique de ces races représente le premier pas pour planifier une gestion des ressources génétiques avicoles basée sur la mise en place de schémas de sélection et de stratégies de conservation. Cet article cherche à évaluer l’état actuel des connaissances sur la diversité morphologique et phénotypique des races avicoles locales et de certaines lignées anciennes en Bulgarie.

La conservación de la biodiversidad avícola supone un gran reto para muchos países. En los últimos años ha aumentado el número de razas locales amenazadas, lo cual ha traído aparejada una pérdida considerable de recursos genéticos. Se ha observado una tendencia similar entre las razas de aves de corral (razas y líneas locales de gallinas, pavos y gansos) establecidas en Bulgaria, parte de las cuales se han perdido ya definitivamente. Actualmente estas razas o líneas están amenazadas y/o en peligro de extinción. La obtención de información mediante la caracterización fenotípica de estas razas constituye el primer paso para la planificación de una gestión de los recursos genéticos avícolas basada en el establecimiento de esquemas de selección y estrategias de conservación. En este artículo se evalúan los conocimientos actuales en relación con la diversidad morfológica y fenotípica de razas avícolas locales y de algunas antiguas líneas productivas en Bulgaria.
