Considerable progress has been made in defining and measuring criteria of trypanotolerance since the late 1970's, when ILCA, FAO and UNEP worked with researchers in 18 West and Central African countries to show clear relationship between level of trypanosomiasis risk and animal performance. Durin...

Phenotypic and genetic parameter estimates of factors related to the performance of trypanotolerant livestock
The exploitation of resistance traits very much relies on the understanding of the mechanisms underlying trypanotolerance, their characterisation in the field, the identification of practical measures of trypanotolerance characteristics, the evaluation of their linkage with final livestock output...

Preliminary results of a study of N'Dama cattle introduced in a metayage system in Idiofa District, Zaire
This paper reviews studies on the relationships between trypanotolerance and performance of cattle, and the genetics of trypanotolerance traits. Results of these studies are used to discuss the practical possibilities of increasing trypanotolerance through selection.
Trypanotolerance is one of the best recognised examples of innate resistance to disease and one of the most thoroughly investigated. Experimental and field studies Reported in this paper are providing the basic tools with which the trypanotolerance trait can be identified and exploited. Evaluatio...

Evaluates the productivity of different breeds of cattle, sheep and goats, particularly trypanotolerant breeds, exposed to different degrees of tsetse challenge under various management systems in 9 West and Central African countries and in three associated East African countries, w. the objectiv...
The efficacies of three trypanocidal drugs, diminazene aceturate, isometamidium chloride and homidium bromide, were evaluated in four representative areas of Cote d'Ivoire with different production systems, degree of integration of different trypanosomosis control approaches and delivery of veter...
