Etude ayant pour objet de determiner, en partant d'observations cliniques faites tout au long de l'annee 1983 au niveau des troupeaux de petits ruminants suivis par le CIPEA, les causes de mortalite les plus connues avant sevrage afin de pouvoir entreprendre des essais visant a leur reduction au niveau des memes troupeaux.

This report reviews key issues in pastoral systems research in tropical areas of sub-Saharan Africa and South Asia with the goal of identifying a ten-year research strategy for pastoral systems research for ILRI.

This study aimed at understanding of existing sheep breeding practices, identifying sheep breeding goals and characterizing the morphological and biometrical characters of Menz and Afar sheep breeds in their habitat as a step towards developing sustainable sheep breeding strategy. The study was conducted by implementing single visit questionnaire, observing and recording of sheep morphological characters, and by recording body weight and body measurements. The survey revealed that the mean sheep flock size per household was 31.6 in Menz and 23.0 in Afar area.

Data on agro-pastoralists' perceptions of climate change and adaptation options were collected from agro-pastoral communities in 7 rural districts of Kenya. Key adaptation strategies for livestock producers include mixing crop and livestock production, destocking, diversifying livestock feeds, changing animal breeds and moving animals to other sites. Desired adaptation options include introducing new breeds and increasing herd size. Additionally, the main barriers to adaptation identified include lack of credit or savings followed by lack of access to land and inputs.

A classification of the major ruminant livestock production systems in West Africa is proposed. The proposed typology has two major classes of systems-sole livestock and crop-livestock. The sole livestock class has two systems (rangeland-based and landless) and the crop-livestock class has three sub-classes (annual crop-livestock, tree-crop-livestock and irrigated/flooded cropland-livestock). Within the 3 crop-livestock subclasses 13 systems defined by the dominant crops are identified.
