Popis:	SummaryThis 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.
