Four experiments, two with sheep and two with goats, were carried out to determine the efficacy of ivermectin, fenbendazole, levamisole, closantel and some of their combinations by faecal egg count reduction tests. In the first experiment, injectable ivermectin, oral ivermectin, fenbendazole and ...

Evidence for multiple anthelmintic resistance in sheep and goats reared under the same management in coastal Kenya
Resistance to naturally acquired gastro-intestinal (GI) nematode parasite infections (predominantly Haemonchus contortus) was studied in 166 Red Maasai; 230 Dorper and 294 crossbred (Red Maasai X Dorper) ewes in the sub-humid coastal region of Kenya. Live weights (LWT), blood packed-cell volume (...

Genetic resistance to gastro-intestinal nematode parasites in red Maasai, Dorper and Red Maasai X Dorper ewes in the sub-humid tropics
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
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...

Genetic resistance to gastrointestinal nematode parasites in some indigenous breeds of sheep and goats in East Africa
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...

Genetic resistance to gastrointestinal nematode parasites in Red Maasai sheep in Kenya
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...
