Milk production characteristics and productivity of N'Dama cattle kept under village management in The Gambia
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...

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...

This study is designed to examine the nature of trypanotolerance, in particular to compare the clinical parameters of infected N'Dama with those of infected Zebu cattle and the variability and repeatability within the N'Dama breed of various disease parameters. Twenty N'Dama and light Zebu cattle...
