D'Ieteren, G.D.M.[Trypanotolerance, an option for sustainable livestock production under disease risk]Trypanotolerance, an option for sustainable livestock production under disease risk

Trypanotolerance, the ability of some livestock species and breeds to survive, reproduce and remain productive under trypanosomosis risk without the aid of trypanocidal drugs, was recognised and exploited by farmers long before research on trypanotolerance began. The exploitation of trypanotolera...


D'Ieteren, G.D.M.[Trypanotolerant livestock, a sustainable and essential component of livestock production systems under trypanosomosis risk in East and Central Africa]Trypanotolerant livestock, a sustainable and essential component of livestock production systems under trypanosomosis risk in East and Central Africa

Earlier research had provided clear indications of an ability of N'Dama cattle to acquire, over time, some control of the Development of parasitaemia following a T. vivax infection but not apparently, following a T. congolense infection. The objective of this study is to further assess the import...

Rowlands, G.J.Authié, E.D'Ieteren, G.D.M.Leak, S.G.A.Mulatu, W.Nagda, S.M.Peregrine, A.S.[An epidemiological study of recurrent trypanosome infection in East African Zebu cattle and its association with drug resistance]An epidemiological study of recurrent trypanosome infection in East African Zebu cattle and its association with drug resistance

Further to understand the mechanisms underlying trypanotolerance, the exploitation of resistance traits relies on the characterisation of these traits in the field and their practical measurement. The successful use of any criteria for identification of trypanotolerant breeds of cattle and/or sup...


D'Ieteren, G.D.M.[Exploitation of trypanotolerance traits in field conditions]Exploitation of trypanotolerance traits in field conditions

While an increasing number of examples of innate resistance to disease are being identified in domestic livestock, resistance to the effect of trypanosomes is one of the best-recognized and most thoroughly investigated. Experimental and field studies reviewed in this chapter are providing the bas...

There is a broad land of territory comprising the subhumid zone and the non-forested areas of the humid zone of West Africa in which a mixture of trypanotolerant, trypano-susceptible, and crossbred cattle are found. Availability of a variety of breeds allows farmers to choose the breeds they judg...

Bovine trypanosomiasis is prevalent in southwest Ethiopia infested with tsetse flies. Since 1986, East African Zebu cattle raised under trypanosomiasis risk in the Ghibe Valley of southwest Ethiopia have been studied to investigate the effects of trypanosmiasis on health and productivity. Approxi...

Presents field research on measurement and use of trypanotolerance criteria to enhance trypanotolerant livestock productivity. Reviews approach and steps taken from the early years to the most recent ongoing or planned experiments carried out by ILCA and its partneres in the African Trypanotolera...

A six year data at Mushie Ranch, Zaire was collected and analysed to quantify the relative importance of four trypanotolerance indicators (ability to control the length of time detected parasitaemic, the ability to control the intensity of parasitaemia, the ability to resist the development of se...
