Abstract. A total of 10,147 female goats from Burkina Faso were scored for 7 body measures and 12 qualitative traits. Sampling included the three main environmental areas and goat breeds of Burkina Faso: the Sahel area (Sahelian goat), the Sudan-Sahel area (Mossi goat) and the Sudan area (Djallonké goat). Overall, the Sahelian goat had the highest values for the all the analysed body measures. Differences between the Sudan and the Sudan-Sahel goat were little. The Burkina Faso goat is mainly spotted (61.92 %) with horns type “Spanish Ibex” (84.05 %), frequent absence of beard (75.33 %) and wattles (70.92 %) and poorly developed udder (73.72 %). The Sahelian population included most individuals with dropping (95.60 %) and curled (73.62 %) ears, whilst most Sudan-Sahel individuals had horizontal ears (73.14 %) and most Sudan individuals had vertical ears (97.88 %). The largest Mahalanobis distance was found between the Sahelian and Sudan areas (7.50) whilst the Sudan and the Sudan-Sahel populations were poorly differentiated (1.15). Discriminant analysis showed that most Sahel and Sudan-Sahel individuals were classified into their source population (79.29 % and 82.69 %) whilst the Sudan individuals (93.40 %) were classified as Sudan-Sahel individuals. Both the canonical and the correspondence analyses showed that the Sahelian and Sudan individuals tended to cluster separately whilst the Sudan-Sahel individuals showed an intermediate distribution but clearly biased toward the Sudan individuals. The Sudan-Sahel (Mossi) population can be considered a result from the genetic contact between Sahelians and Sudan goats.
