Discusses factors influencing liveweight in a range of trypanotolerance network situations. Analyses liveweight traits, viz, dam liveweights at parturition and weaning, dam liveweight change between parturition and weaning, progeny liveweights at birth and weaning and progeny pre-weaning daily gain.

Factors influencing liveweight in a range of network situations
Trypanosomiasis, a disease transmitted by the tsetse fly, is a major constraint to livestock production and mixed farming in Africa. Due to the prevalence of trypanosomiasis and skin diseases in much of Zaire, it was concluded that cattle production was only feasible through the introduction of t...

The economics of recently introduced village cattle production in a tsetse affected area. (I): Trypanotolerant N'Dama cattle in Zaire
From biological data collected between January 1986 and December 1989, and economic data collected during 1988, 10-year projections of herd structure, production, and economic and financial returns were calculated for 13 village cattle herds at two village sites in the Gambia. The analyses indica...

Evaluates teh criteria for trypanotolerance including three related characterstics, v.z. the ability to control parasitaemia, the ability to control anaemia, and the ability to develop an effective immune response.
