The Trypanotolerant Livestock Network in West and Central Africa

Describes the background to the problem of trypanosomiasis in Africa, identifying Bos taurus & Bos indicus types of trypanotolerant breeds & discussing the importance of their use in the exploitation of tsetse-infested areas of Africa. Examines the establishment of a network of trypanotolerant livestock situations throughout West and Central Africa, & summarizes the current network situation, particularly w. respect to the productivity of trypanotolerant & trypano-susceptible breeds under dif. levels of risk & under dif. management regimes

N'dama cattle productivity at Teko Livestock Station, Sierra Leone, and initial results from cross-breeding with Sahiwal

Examines the productivities of N'Dama cattle, introduced Sahiwal cattle, and Sahiwal X N'Dama crossbred at the Teko Livestock Station, Sierra Leone. Evaluates environmental and genetic effects relating to breed group, month and year of parturition or birth, age, sex, individual cow etc. as appropriate for each performance trait

Trypanotolerant livestock in West and Central Africa. Volume 2. Country studies

Information on trypanotolerant livestock in Senegal, the Gamia, Guinea Bissau, Guinea, Sierra Leone, Liberia, Mali, Upper Volta, Ivory Coast, Ghana, Togo, Benin, Nigeria, Cameroon, Central African Republic, Gabon, Congo and Zaire, particularly livestock numbers & distribution, information available on trypanotolerant cattle, sheep & goats, research and development activities, w. a selected bibliography

Trypanotolerant livestock in West and Central Africa. Volume 1. General study

Review of the classification, geographic distribution, animal performance and productivity of trypanotolerant cattle, sheep and goats in 18 countries of west & central Africa, particularly N'dama cattle, West African Dwarf Shorthorn, and Zebu x N'Dama crossbreeds. Discussion on potential utilization and conservation of trypanotolerant livestock and recommendations for further research

Evaluation of the productivities of Djallonke sheep and N'Dama cattle at the Centre de Recherches Zootechniques, Kolda, Senegal

Presents results of analysis of the reproductive performance, viability and growth performance traits of Djallonke sheep & N'dama cattle kept at the Centre de Recherches Zootechniques in Senegal; includes productivity indices for the two species built on the basis of the analyzed data

The productivity of trypanotolerant livestock in West and Central Africa

Reports on the productivity of trypanotolerant breeds in 18 West and Central African countries. Traits examined included reproductive performance, cow and calf viability, milk production, growth and body weight of cattle within a village or ranch management system and under four degrees of trypanosomiasis risk levels. The results were used to build productivity indices, and compared productivity of these breeds with crosses of zebu and humpless cattle. A coordinated research and project network is recommended
