In this overview, the results of studies in France were given on the genetic variability in resistance to helminth parasites in Romonov and Merino d'Arles sheep and Saanen and Alpine goats. The paper focusses on diversity of helminth parasites, innate vs acquired resistance, criteria for genetic ...
This paper focusses on within-breed genetic variation in resistance to endoparasites in the Australian Merino. It stresses possible differences in the Merino resistance, simply because of different history of management. The Australian Merino was introduced into Australia 200 years ago. It has al...
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 ...
The paper focusses on the genetic control of immunoresponsiveness in Trichostrongylus selection lines. It discusses results from other selection programmes in which some characterisation of the immune - response system has been undertaken. It is Reported that some aspects of this work may not hav...
This study was conducted to determine the long term effect of supplementation of L. pallida and S. sesban on growth and reproductive performance of male Ethiopian highland sheep and goats fed teff straw (Eragrostis tef) basal diet. The results show that there was no significant effect of the diff...
The paper examines levels of mortality and morbidity from birth to maturity of African small ruminants in a range of traditional (Pastoral, agropastoral, mixed smallholder and modern (research station, ranch) systems. Goat mortality is ususally heavier than that of sheep prior to weaning where tw...
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...
