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...

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...

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.

Over a 12-month period 313 (8.4 percent) out of 3727 slaughter cattle sampled at Ibadan abattoir were found to be infected with trypanosomiasis. Infection rates were higher in the dry than in the wet season ranging from 20.4 percent in November to 2.8 percent in May. Overall PCV levels were highe...
