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...

Analyses of herd offtake and marketing of live and dressed trypanotolerant cattle: A case study from the Gambia
Presents the summary of livestock breed evaluation and characterisation work in the Gambia. Discusses the on-farm work undertaken by the European Economic Community (EEC), which was intially executed jointly with International Livestock Center for Africa (ILCA) and International Laboratory for Re...
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...

Effects of nutrition on degree of anaemia and liveweight changes in N'Dama cattle infected with trypanosomes
The effects of trypanosome and helminth infections on health and production parameters in 2000 village N'Dama cattle were assessed periodically. Blood examination showed Trypanosoma congolense and Trypanosoma vivax to be prevalent, while strongylid-type eggs were those most frequently encountered...

Effects of trypanosome and helminth infections on health and production parameters of village N'Dama cattle in The Gambia
Over the last two to three decades, West Africa has witnessed considerable changes in land use. Unprecedented increases in human population combined with changes in climatic patterns have reduced per capita arable land traditionally available for agricultural production. In the livestock sub-sect...

A total of 505 lactation records from 340 cows of the N'Dama breed were matched with health records recorded on the same animals over a period of 4 years. The objective of the analysis was to establish linkages between 3 criteria of trypanotolerance namely, frequency of infection, control of para...
