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...
Presents preliminary results of a study of N'Dama cattle introduced in a metayage system in Zaire. Studies tsetse relative densities, tsetse challenge, corrected tsetse challenge, trypanosome prevalence and PCV in gallery forest, savanna woodland and grass savanna areas. Also presents data on fee...
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.
Studies the productivity of Zebu cattle at Mkwaja ranch in Tanzania, upgraded by the importation of Boran bulls and semen from Kenya and maintained under the successful trypanocidal drug strategy; discusses the proper management of acaricides and anthelmintics, as well as bacterial and viral vacc...
