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...

A study was conducted to assess the correlation between criteria of trypanotolerance and production. N'dama post weaner cattle with different weights and from different age groups were studied for weight gain, packed cell volume (PCV) and for the presence of trypanosomes. The analysis approach wa...

Matching animal health and performance data were recorded over the 2 year period from weaning at 10 months of age on 225 N'Dama cattle in a high natural tsetse challenge situation in Zaire. Four parameters that are regarded as possible indicators of trypanotolerance, species of trypanosomes detec...
