A study undertaken to determine reproductive efficiency in the village herds of N'Dama cattle in The Gambia. Investigates the relationships among reproductive efficiency, environmental and disease factors and assesses the effect of nutrition on the onset of ovarian activity in the post-partum per...

Reproductive performance of N'Dama cattle kept under village management in The Gambia
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...

Susceptibility to African trypanosomiasis: Studies in cattle and mice
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...

This article attempts to evaluate the current state of knowledge on questions such as, to what extent is inheritance important and how is it influenced by environmental factors; what are the mechanisms underlying increased resistance; and how productive are these breeds under various levels of ch...
