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
Studies the health and performance of two strains trypanotolerant N'Dama cattle, susceptible Nguni cattle and their crosses over a three-year period, 1983-1985, at OGAPROV ranch in Gabon; presents the influences of breed and animal age on the prevolence, species and intensity of trypanosome paras...

Health and productivity of trypanotolerant and susceptible cattle exposed to trypanosomiasis in Gabon and the impact of strategic chemoprophylaxis
Discusses the productivity of N;Dama cattle at Kolo and Mushie ranches (Zaire). Includes data on productivity under zero (Kolo) and high (Mushie) trypanosomiasis risk (1984-86). Compares the productivity of Boran and N'Dama cattle under ranch management at five sites in Africa.
The prevalence, species and intensity of trypanosome parasitaemia in different livestock species, breeds, age groups and management systems are reported from Togo for trypanosotolerant sheep and goats in the Sokode area. The effects of these trypanosome parasitaemias on health and production trai...

Effect of trypanosome infection on livestock health and production in Togo
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
Emphasises the importance of trypanotolerance by indicating that trypanotolerant breeds were at least as productive as other indigenous African breeds in areas of zero to low tsetse challenge and that in areas where tsetse challenge was substantial, only trypanotolerant breeds could survive. It w...

N’Dama cow and calf viabilities, parturition intervals, cow parturition and weaning weights and calf weaning weights were recorded during a three year period, January 1984 to December 1986. The management system was the same at Mushie and Kolo ranches (Zaire) where trypanosomiasis risk was high a...
The prevalence, species and intensity of trypanosome parasitaemia over an eighteen-month period, February 1986 to July 1987, are reported for some 700 N`Dama cattle managed in twenty-five village herds in forest and plateau areas of Idiofa, Zaire. The effect of trypanosomiasis and other diseases ...
