Discusses factors influencing liveweight in a range of trypanotolerance network situations. Analyses liveweight traits, viz, dam liveweights at parturition and weaning, dam liveweight change between parturition and weaning, progeny liveweights at birth and weaning and progeny pre-weaning daily gain.

Assessment of adult female tick burden was performed on 160,151 and 150 yearling sheep in coastal Kenya at the end of three consecutive infestation periods, respectively. The main attachment sites of fully engorged female ticks were ears, head, body sides, perianal and scrotal/udder regions. Aver...

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 ...

The study was carried out in three locations in the Mombasa region along the kenyan coast. A total of about 800 ewes (Dorper) were mated with Dorper and Red Maasai rams. Mating was restriced to a 6-week period and at night time only. Lambing seasons were targeted for March/April and November/Dece...

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 (...
