Animal breeding and productivity studies in Africa

Summarises the work that ILCA is doing to assemble what information is available on livestock breeds and breeding in sub-Saharan Africa

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

Trypanotolerant livestock in West and Central Africa. Volume 3. A decade's results

This volume presents major results obtained since the publication of volume 1 and 2 and updates national data on trypanotolerant cattle. The first part analyses populations and their trends between the two surveys and reviews research activities and development activities. It also gives recent information available on the potential and utilisation of trypanotolerant livestock. Part two presents recent data for the 18 study countries, as well as for Equatorial Guinea which was not covered in volume 2. This information should be studied in conjuction with volume 2 for an overall and updated view of trypanotolerant livestock production in each country. Countries are discussed in the same order in both volumes. An additional section on major developments occuring during the study period has been included at the end of each country study

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

Crossbred dairy cattle productivity in Arsi region, Ethiopia

Presents results of analyses carried out on a range of performance traits and productivity estimates for indigenous Arsi & Zebu cattle and their crosses with Jersey & Friesian, maintained for milk production at Asela station & on smallholder farms in the Arsi region of Ethiopia; includes data on age at first calving, calving interval, breeding efficiency, milk yield & composition and body weight
