LIVESTOCK DISEASES IN PERIURBAN DAIRY SYS TEMS IN SUB-SAHARAN AFRICA - ILCAS APPROACH

Dairy production to supply African urban centers is one of the dynamic livestock sectors in sub-Saharan Africa (periurban dairy farms). Ther e is a modification in the relative impact of economically important d iseases: these farms have an increased capacity to control the major t raditional African diseases through genetic or health interventions, h ence favouring the emergence of diseases of intensification, which aff ect dairy production. In this framework, the International Livestock C entre for Africa is starting a research programme which aims, by an ec opathological approach, to judge the true existence of this pathology as opposed to the major African diseases, and to compare its economic importance in various agroecological zones.
