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.

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...

Discusses trypanotolerant livestock, commonly accepted by livestock producers that trypanotolerance is the ability of an animal to survive, reproduce and be productive without the necessity for trypanocidal drugs in an environment with trypanosomiasis, risk. Discusses constraints in conducting re...

The evaluation of the interactions between trypanosome risk, disease control methods and the productivity require high consideration so that sustainable strategies that are best adaptable to the specific needs, constraints and opportunities of the production systems are worked out. There is no un...

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...

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...
