Summary

This paper summarises preliminary results of a survey conducted as part of a large effort to systematically collate information aimed at assessing the status of cattle genetic resources of sub-Saharan Africa. The 146 indigenous breeds/strains identified from the survey are classified into nine broad groups (Humpless Longhorns, Humpless Shorthorns, Large East African Zebu, Small East African Zebu, West African Zebu, Sanga, Zenga, Recently Derived Breeds and Commercial Composites) some of which are further subdivided into several groups (based on possible genetic relationships) and clusters (based on eco-geographical locations). Each breed is then described in terms of location, physical characteristics, adaptive attributes, if known, current main uses and status in terms of qualitative or quantitative indication of trends, where available, and presence or absence of programmes for its management or further development.

Résumé

Cet article présente un résumé des résultats préliminaires d'une enquête conduite au sein d'un programme plus large mené pour recueillir sistématiquement l'information permettant d'évaluer la situation des ressources génétiques des bovins dans l'Afrique Sub-saharienne. Les 146 races/lignes identifiées par l'enquête ont été classées en neuf groupes: sans bosse à longues cornes, sans bosse à courtes cornes, grand zébu de l'Afrique de l'est, petit zébu de l'Afrique de l'est, zébu de l'Afrique de l'ouest, Sanga, Zenga, races dérivées récentes et lignées commerciales. Certains de ces groupes ont été divisé selon leur relation génétique en d'autres groupes, et en sous-groupes suivant le lieu éco-géographique de provenance. Chaque race est donc décrite suivant la situation, les caractéristiques physiques, la capacité d'adaptation, si elle est connue, et l'utilisation principale et la situation du point de vue de la qualité ou quantité selon les indications du marché, si elles sont disponibles, ainsi que la présence ou absence de programmes pour leur gestion ou futur développement.
