Centre International pour l'Elevage en Afrique[Production Animale Dans Les Regions D'Afrique Infestees Par les Glossines]Production Animale Dans Les Regions D'Afrique Infestees Par les Glossines

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...

Presents field research on measurement and use of trypanotolerance criteria to enhance trypanotolerant livestock productivity. Reviews approach and steps taken from the early years to the most recent ongoing or planned experiments carried out by ILCA and its partneres in the African Trypanotolera...

ILCA's achievements and future plans]Field research on measurement and use of trypanotolerance criteria to enhance trypanotolerant livestock productivity. 1. ILCA's achievements and future plans

The controversy over the possible impacts of trypanosomiasis control on African ecological and socioeconomic systems exemplifies the classic polarization of arguments for development and conservation. On one hand, Africa's rapidly expanding human populations require expanded food supplies, and tr...


Reid, Robin S.Curry, J.J.Swallow, B.M.Mukhebi, A.W.Perry, Brian D.Ellis, J.E.[Ecological, social and economic impacts of trypanotolerance: collaborative research in Central and West Africa]Ecological, social and economic impacts of trypanotolerance: collaborative research in Central and West Africa

Factors affecting the expression of trypanotolerance are discussed. Some of the factors which could influence the feeding preference of tsetse are physical - skin thickness, skin rippling; visual - coat colour, size; olfactory - breath, urine, skin secretions; behaviour - tail flicking, head swin...


Leak, S.G.A.D'Ieteren, G.D.M.Rowlands, G.J.[Factors affecting estimation of tsetse challenge and the expression of trypanotolerance]Factors affecting estimation of tsetse challenge and the expression of trypanotolerance

A six year data at Mushie Ranch, Zaire was collected and analysed to quantify the relative importance of four trypanotolerance indicators (ability to control the length of time detected parasitaemic, the ability to control the intensity of parasitaemia, the ability to resist the development of se...

Recent results quantifying trypanotolerance indicators]Field research on measurement and use of trypanotolerance criteria to enhance trypanotolerant livestock productivity. 2. Recent results quantifying trypanotolerance indicators

Evaluates in detail how environmental and stress factorts affect trypanosome infection in N'Dama cows and their calves, the linkages with curative drug treatment given under the management regime prevailing, the linkages with anaemia control as measured by packed red cell volume (PCV), and the re...
