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...
Six herds of N'Dama cattle exposed to low to medium tsetse challenge in areas surrounding the village of Keneba in the Kiang West District of The Gambia, were monitored. The degree of anaemia, as measured by PCV in 2- to 5-year-old female N'Dama cattle during the first month of detectable trypano...
Investigates the time of appearance and the persistence of antibodies in N'Dama cattle bitten by infected tsetse flies under controlled conditions, the serology of village animals exposed to natural trypanosomiasis risk and the time of appearance and duration of anti-trypanosomal antibodies throu...
Reports a study of the interaction between trypanosome infections and physiological status on health and productivity in N'Dama cattle managed under traditional husbandry practices in The Gambia. Discusses production environments and herd management, parasite kinetics, erythropoietic response and...
Examines the productivity characteristics of village N'Dama cattle exposed to different levels of trypanosomiasis challenge in The Gambia over a 3-year period. 60 lactating cows in which Trypanosoma congolense and T. vivax had been detected on blood examination were compared with 50 cows which ha...
The Berenil provides a means of estimating the trypanosomiasis challenge presented to cattle independent of, and therefore complementary to, the collection of tsetse data and of prevalence rates of infection in cattle. In areas where trypanotolerant cattle predominate, the Berenil Index has seldo...
