In Casamance, Senegal Oriental and The Gambia are found nearly 30% of the total N'Dama cattle population and nearly 9% of the total Djallonke sheep population of Africa. The Centre de Recherches Zootechniques, Kolda is centrally located in this region and has been recording information on performance traits of these two breeds since 1973.
In 1981 the International Livestock Centre for Africa (ILCA) provided scholarships for two research scientists from the Institut Senegalais de Recherches Agricoles (ISRA) to undertake over a five month period the extraction, analysis and interpretation of available data in collaboration with the ILCA Nairobi breed productivity and trypanotolerance team.
This report presents an analysis of the carefully recorded productivity data collected to 1981. The joint collaboration has enabled data analysis methods to be developed that will permit maximal early use of further information currently being recorded.
