Matching information on animal health and performance aspects was collected from 255 N'dama post-weaners from September 1986 to December 1991. Records covered for each animal a two years period from weaning at 10 months of age until 34 months of age. Curative trypanocidal drug treatment was given...

Quantification of the relative importance of trypanotolerance measurements on productivity of N'Dama cattle (Addendum)
The genetic components of trypanotolerance measurements must be determined in well controlled on going production systems where the necessary identification and/or quantification of environment and genetic effects are possible. A resource population has been established in the Mushie District Ban...

A N'Dama cattle resource population for research on trypanotolerance
Trypanosome infection was detected by the dark ground/phase contrast buffy coat microscopic technique in N'Dama cattle in a high natural tsetse challenge situation in Zaire. The data were used to compare the pattern of infection in very young animals and in their dams, and to evaluate how the pat...

Patterns of Trypanosoma vivax and T. Congolense infection differ in young N'Dama cattle and their dams
Host ability to control the Development of trypanosomes is a major component of trypanotolerance. However, practical indicators of the parasite control capability have still to be identified as they rely on the availability of more precise diagnostic techniques that could be carried out at the fa...

Trypanosome antigen test to characterise infection status in N'Dama cattle
Earlier research had provided clear indications of an ability of N'Dama cattle to acquire, over time, some control of the Development of parasitaemia following a T. vivax infection but not apparently, following a T. congolense infection. The objective of this study is to further assess the import...

Ability to acquire resistance to trypanosome infections and growth of N'Dama cattle
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...
