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
Studies the within-and between-breed differences in resistance to natural infection with gastro-intestinal parasites and identifies genetic markers to aid in the selection of animals. Data analysed include PCV (Packed Cell Volume), live weight from birth to 360 days and faecal egg counts.

Resistance to gastro-intestinal parasites in Dorper and Red Maasai-Dorper crossbred sheep
This Report compares the efficacies of three anthelmintics, each belonging to one of the broad spectrum groups. It also identifies the genera of resistant worms through larval culture. The study was conducted on a commercial farm where anthelmintics had been used intensively. The results show cle...

Evidence for multiple anthelmintic resistance of gastrointestinal nematodes in sheep in coastal Kenya
The economic and biological efficiency of cotton seed cake (CSC) and molasses urea block (MUB) supplementation to control gastrointestinal nematode parasites was examined in artificially infected Horro and Menz lambs from 3 to 12 months of age. The factorial O.xperimental design involved 2 breeds...

Economics of gastrointestinal nematode parasite control: The case of protein supplementation
The paper reviews the limited data available on both between-and within-breed genetic variation for resistance to helminthiasis in cattle, sheep and goats in the tropics. Topics covered include criteria of resistance, resilience or tolerance, parasite species and mode of infection, parameters to ...
