Rey, B.Lebbie, S.H.B.Reynolds, L.[Small ruminant research and development in Africa: proceedings of the Third Biennial Conference of the African Small Ruminant Research Network : UICC, Kampala, Uganda, 5-9 December 1994]Small ruminant research and development in Africa: proceedings of the Third Biennial Conference of the African Small Ruminant Research Network : UICC, Kampala, Uganda, 5-9 December 1994

Economic constraints and opportunities for improving small ruminant production systems in sub-Saharan Africa must be understood as the basis for developing interventions. However, most national agricultural research systems (NARS) face a shortage of livestock economists, and biological scientists...

From its establishment in 1974, the International Livestock Center for Africa (ILCA) has followed a systems approach. Research planning and implementation incorporates description of systems, diagnosis of constraints, development and evaluation of interventions, and transfer of appropriate techno...

This paper attempts to demonstrate the importance of livestock in African Agriculture through an analysis of the major factors affecting livestock density and species composition. In the zonal analysis, the general distribution patterns have been summarised by subdividing the continent into five ...


Leeuw, P.N. deRey, B.[Analysis of current trends in the distribution patterns of ruminant livestock in tropical Africa]Analysis of current trends in the distribution patterns of ruminant livestock in tropical Africa

Annual estimates of production traits over a 22 year period (1965-1987) for Black Head Persian sheep (BHP) from Malya and West Kilimanjaro research centers in Tanzania were utilized to analyse variation of flock productivity over time. Principal component analysis was used to anlyse the variation...

Autor: Rey, B.

This overview aims at browsing the scene of action for research on the resistance of small ruminant to endoparasites in sub-Saharan Africa. After recalling the main sheep and goat breeds, it describes the geographic distribution of these populations in the continent, mentions the farming systems ...

This document is based on the deliberations and outputs of two ILCA in-house workshops held in 1992, and of numerous individual contributions by ILCA scientists. This work has similarities with the ILCA project on smallholder market-oriented dairying. Factors influencing development of market-ori...

A survey was conducted on 224 randomly selected farmers, comprising those participating and non-participating in a goat corssbreeding project in Burundi, and 54 farmers chosen as `breeders' by the project. Participating farmers were similar to the average goat farmers in the region in terms of la...

197 goat flocks from the province of Ngozi in Burundi were monitored in 1990 and 1991. Most offtake corresponded to sales, with little home slaughtering practiced. Flock offtake rate for farmers with crossbred goats was lower than for non-participating farmers, while their flocks remained of simi...
