Presents results of experiments to determine phenotypic & genotypic relationships of the abilities to control parasitaemia, resist anaemia or develop an immune response with animal performance in terms of daily weight gain, maintenance of packed cell volume levels and disease prevalence in trypan...

Selection in trypanotolerant cattle breeds in Africa
In Mushie ranch, 157 N`Dama progeny of four sires, 95 males and 62 females, were used to estimate the habitability levels for aspects of parasitaemia, anemia control, immune response and animal performance. The males were exposed to a high natural trypanosome challenge, and body weight, trypanoso...
Discusses the genetic aspects of criteria of trypanotolerance including parasitaemia, anaemia control and immune response. Includes data on heritability estimates for daily liveweight change, for PCV under low & high trypanosome prevalence, and for number of treatments required in four periods af...
