A study was carried out from 1994 to 1996 to compare the resistance to naturally acquired gastrointestinal (GI) nematode infections (predominantly Haemonchus contortus) of 88 Galla and 114 Small East Africa (SEA) goats (does) in the sub-humid coastal region of Kenya. Live weights (LWT), blood pac...

Myrsine africana L. and Rapanea melanophloeos L. belong to the plant family Myrsinaceae. Various rural communities in Kenya, such as smallholder farmers and pastoralists, use them to treat their livestock. The anthelmintic effects/activities of leaves and fruits of M. africana and fruits of R. me...

Sabi and Dorper ewes were evaluated for resistance to gastro-intestinal nematode parasites (predominantly Haemonchus contortus) at the Matopos Research Station in Zimbabwe. Live weights (LWT), blood packed red cell volume (PCV) and faecal egg counts (FEC) were recorded at mating, 1 month before...

Research in Kenya has confirmed that Red Maasai sheep are more resistant to gastrointestinal parasites than Dorper sheep and has shown that Small East African goats are more resistant than Galla goats. There is no difference in resistance between the Menz and Horro sheep breeds in Ethiopia. Herit...

This study is evaluating the resistance of Red Maasai sheep to endoparasite infections relative to Dorper sheep and a range of Red Maasai x Dorper crosses. The results confirm previous reports that both Red Maasai ewes and lambs are more resistant to endoparasites (predominantly Haemonchus contor...

The evidence for both between-and within-breed genetic variation for resistance to gastrointestinal (GI) nematode parasites is reviewed. It is concluded that much of the published research on breed characterisation for resistance suffers from poor experimental design. Prior to the initiation of a...
