Ayalew, W.Dorland, A. vanRowlands, G.J.[Design, execution and analysis of the livestock breed survey in Oromiya Regional State, Ethiopia]Design, execution and analysis of the livestock breed survey in Oromiya Regional State, Ethiopia

Trypanosomiasis, a disease transmitted by the tsetse fly, is a major constraint to livestock production and mixed farming in Africa. Due to the prevalence of trypanosomiasis and skin diseases in much of Zaire, it was concluded that cattle production was only feasible through the introduction of t...


Itty, P.Rowlands, G.J.Minengu, M.Ngamuna, S.Winkel, F. vanD'Ieteren, G.D.M.[The economics of recently introduced village cattle production in a tsetse affected area. (I): Trypanotolerant N'Dama cattle in Zaire]The economics of recently introduced village cattle production in a tsetse affected area. (I): Trypanotolerant N'Dama cattle in Zaire

Trypanosomiasis, a disease transmitted by the tsetse fly, is a major constraint to livestock production and mixed farming in Africa. This study examines the economics of the village production of trypanotolerant cattle recently introduced in an affected area of Togo that was previously virtually ...

A cross-sectional stratified random sample survey of 1755 households in the Kenya highlands was conducted between June 1996 and April 1998 to quantify cattle population dynamics in smallholder herds. The free-, semi-zero- and zero-grazing systems practised represented increasing levels of intensi...

This workshop was conceived in recognition of the fact that, over the years, a great deal of research has been conducted on trypanotolerance. With the advent of new and powerful means to identify markers and genes controlling traits of interest, and with the developments in animal breeding bringi...

In 1986 a project was set up to determine the constraints to production of Zebu cattle under trypanosomiasis risk in the Ghibe valley. Approximately 1800 East African Zebu cattle (EAZC) were resident within the Ghibe valleey during the experimental period (1986 - 1992) and were maintained under t...

The objective of this study was to apply transition models to distinguish between factors associated with both incident and persistent trypanosome infections. Data collected from 1561 cattle were analyzed from a long-term study involving 8 herds in which both trypanosome infections (a total of 56...
