ABSTRACT
Hair sheep in Senegal are of two general types: the Djallonke found in the high-rainfall sections of the southern part of the country and the Sahelian type in the arid northern part of the country. The Kolda Station is located in a climatic zone similar to that described by Berger for the Bouake Station in Ivory Coast, and the mean performance values for Djallonke sheep at Kolda are remarkably similar to those reported from Bouake. Pneumonia and dysentery were identified as the most important causes of mortality, with dysentery occurring in spite of a regular program to control internal parasites. The hair sheep of the Sahelian zone of Senegal are considerably larger than Djallonke sheep. When weighed for the study, the sheep were in relatively thin condition due to the sparse forage in the area. The incidence of multiple births was low, which is in agreement with data presented by Wilson for other Sahelian sheep.
