Autor: Trail, J.C.M. D'Ieteren, G.D.M.

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...

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...

Autor: Trail, J.C.M. D'Ieteren, G.D.M. Murray, M.

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.
