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
This study quantifies comprehensively both within and between breed differences in resistance to natural infection with gastrointestinal parasites. This research programme was developed from an earlier study in coastal Kenya involving Dorper and Red Maasai X Dorper sheep. It is now part of an ILC...

Genetic resistance to gastrointestinal parasites in Dorper and Red Maasai X Dorper lambs in coastal Kenya
Disease resistance/tolerance, productivity and efficiency of Red Massai and Dorper sheep evaluated in experiments at the Kenya coast (humid environment) and the Kenya highlands (Semi-arid environment). There were important breed by location interactions for LWT, mortality rates and reproduction r...

Comparison of Red Maasai and Dorper sheep for resistance to gastro-intestinal nematode parasites productivity and efficiency in a humid and a semi-arid environment in Kenya
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
The Menz and Horro highland sheep breeds are being evaluated at the ILCA Debre Birhan research station in Ethiopia for between-and within-breed genetic variation for resistance to internal parasites. The experimental design involves mating, for each breed, 150 ewes with 10 rams to lamb at the beg...

Preliminary evidence for genetic resistance to endoparasites in Menz and Horro lambs in the highlands of Ethiopia
Sustainable livestock improvement cannot be guaranteed for most tropical areas of the world without utilization of the evolutionary adaptation of the indigenous livestock breeds. The paper summarizes the adaptive traits of indigenous tropical breeds, presents a case for their evaluation and discu...

Genetic resistance to artificially acquired gastrointestinal parasites was studied in 49 Horro and 103 Menz breeds of Ethiopia. The experimental design involved 2 breeds, 2 infection treatments (Infected vs Non infected) and 3 dietary protein treatments using 152 lambs assigned to the 12 treatmen...
