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...

Presents the Orma Boran field observations carried out under tsetse fly challenge on Galana ranch in Kenya since 1980. Their response to trypanosomiasis has been compared to that of the ranch bred Kenya (Galana) Boran. The mean monthly prevalence of trypanosomiasis observed in Orma steers over fi...

Breeds of cattle, sheep and goats have been identified which are genetically resistant and/or tolerant to gastro-intestinal nematode parasites. Mapping and cloning of resistant genes will facilitate Development of new breeds of livestock, which combine this important disease resistance trait with...

Genome-wide quantitative trait locus (QTL) mapping was used to evaluate the genetic basis of resistance to Helgmosomides polygyrus in an F2 cross of SWR and CBA mouse strains that are resistant and susceptible, respectively, to infection. 25 significant QTL affecting at least one of the resistanc...

Red Maasai [Masai] and Dorper sheep were evaluated for their resistance to gastrointestinal nematode parasites (predominantly Haemonchus contortus), productivity and efficiency in experiments undertaken at the Kenyan coast (humid environment) and the Kenya highlands (semiarid environment). It was...
