This paper undertakes an ex ante economic analysis of research on how resistance to trypanosomosis - a dominant livestock disease in Africa - can be maintained and enhanced while retaining and reinforcing characteristics of economic importance to farmers, and on how 'trypanotolerance' can be impa...

An ex ante economic and policy analysis of research on genetic resistance to livestock disease: Trypanosomiasis in Africa
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...

Cette etude examine la production de troupeaux bovins villageois principalement trypanotolerants, dans la region de Boundiali, au nord de la Cote d'Ivoire. Le but est d'evaluer la rentabilite de ce systeme de production dans une region affectee par la trypanosomose et d'identifier les principales...

Disease interactions in cattle and sheep in northern Cote d'Ivoire
Agricultural extension systems across Africa are under great pressure to become more efficient and effective. Whereas proposals abound as to what African governments should do in order to achieve these goals, those addressing how they might do so are rare. The literature still offers little guida...

An epidemiological study of recurrent trypanosome infection in East African Zebu cattle and its association with drug resistance
An average of 840 East African Zebu cattle have been monitored in the Ghibe valley, south west Ethiopia since 1986. Despite a high prevalence of drug resistance, regular Berenil treatment appears to have maintained these cattle at reasonable levels of productivity. However, when corrected for fre...

Field research on measurement and use of trypanotolerance criteria to enhance trypanotolerant livestock productivity. 1. ILCA's achievements and future plans
Factors affecting the expression of trypanotolerance are discussed. Some of the factors which could influence the feeding preference of tsetse are physical - skin thickness, skin rippling; visual - coat colour, size; olfactory - breath, urine, skin secretions; behaviour - tail flicking, head swin...
