Data on approximately 4,000 head of N'Dama cattle kept in 60 herds under traditional management systems in The Gambia were analysed to estimate annual herd offtake rates during a 5 year period (1986-1990). Farm-gate sale prices and weight at sale of 428 cattle were analysed by least-squares ANOVA...

African buffalo (Syncerus caffer) and trypanotolerant N'Dama cattle were compared for their resistance to overcome Trypanosoma congolense and T. vivax infections. Several compartments from the immune system were followed during the infections and compared between the two species. Several parmaete...

The prevalence of ticks in cattle, sheep and goats in three group ranches in the arid area of Kajiado District in Kenya was studied. Four differet genera were identified from a total of 2,546 ticks collected. Of all the ticks collected, Rhipicephalus constituted 80.45 percent, Amblyomma 16.3 perc...

Blood samples were collected during the rainy and dry season months from a total of 247 traditionally village managed Muturu cattle randomly selected from five Local Government Areas (LGAs) of Benue State, Nigeria. The blood samples were examined for the presence of Trypanosome organism through p...

Tick-borne diseases (TBDs) are a major economic constraint to livestock production in sub-Saharan Africa. ILRI is focussing on developing a range of products, such as vaccines, diagnostics and decision support services to underpin improved control programmes against these diseases. We have develo...
