The paper reviews the evidence of genetic resistance to endoparasites both within and between breeds of sheep and goats and assesses the possibilities of breeding for increased resistance. In light of this evidence, ILCA has developed a Pan-African research programme to investigate and characteri...

A review of genetic resistance to endoparasites in small ruminants and an outline of ILCA's research programme in this area
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...

Systems approach to livestock development oriented research: ILCA's experience
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...

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...
