Evaluates possible contributions of the antigen-detection enzyme immunoassays (ELISA) for the diagnosis of Trypanosoma vivase, T.congolense, and T.Bucei infections in N'Dama cattle in Gabon, Central Africa. The assays are based on monoclonal antibodies which recoginse trypanosome antigens specifi...

Use of antigen-detection immunoassays in assessment of trypanotolerance in N'Dama cattle
A study undertaken to evaluate the degree of genetic determination in the control of development of anaemia in N'Dama post-weaner cattle exposed to a medium natural trypanosome challenge during a short term test for trypanotolerance. The heritabilities of average pcv, lowest pcv reached, and grow...

Evaluates components of a short term test for trypanotolerance criteria in N'Dama post-weaners exposed to a medium natural trypanosome challenge in Gabon; compares the effectiveness of different measures of control of development of anaemia; and measures the post-test recovery of packed red cell ...

Evaluation of a field test for trypanotolerance in young N'Dama cattle
Presents two different methods of treatment of trypanosomiasis, prophylaxis and therapeutic treatments, for N'Dama cattle, Nguni cattle and their crosses in Gabon; monitors the recording of packed cell volume percent (PCV), trypanosome detection and bodyweight estimation; and studies animal healt...

The trypanotolerance network. 2. A study on health and productivity of N'Dama, Nguni and their crosses under quantified levels of tsetse challenge in Gabon. 2.2. - The influence of trypanosomiasis on the health status and performance
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...
