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...
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...
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...
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...
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...
Information on geographic distribution of tsetse fly, livestock numbers & distribution, performance of N'Dama cattle, animal diseases, herd composition and management, and sheep and goat population in The Gambia with data on research centres & programmes, and development projects.
