This manual has been prepared for use by trainees and trainers of forage seed production. It is intended as a practical guide to cover some of the basic principles of production of quality forage seeds. The manual is divided into five chapters. The first chapter outlines field multiplication prac...
Describes the characteristics of dairy production and processing in South Darfur and provides an analysis of the way in which pastoral families vary their diets according to seasonal food shortages and shifting terms of trade between milk and food grains.
The major clinical diseases of crossbred dairy herds were investigated for two years in a milk shed in Addis Ababa. Animals in 38 herds were randomly selected and visited weekly. Diagnosis of diseases and causes of death were based on clinical observation. Disease conditions were categorized into...

Livestock kept or produced in smallholder farming systems are an important component of the agricultural economy in the developing world. The role of livestock on smallholder farms varies widely, providing draught power for crop production or as a production activity for subsistence needs or mark...

Small ruminant genetic resources (SRGR) in sub-Saharan Africa (SSA) play an important role in the welfare of the people, especially the resource poor. SSA is endowed with a diverse SRGR maintained under equally diverse and complex production systems. The public and the private sectors are key act...

An exploratory survey was undertaken to describe and quantify the magnitude of lameness in 964 dairy cattle between October and December 1999 under urban (Addis Ababa), peri-urban (Sebeta and Kaliti), and urban farms in a secondary town (Debre Zeit). Based on herd sizes, these farms were classifi...

A cross-sectional study of bovine brucellosis was carried out from May to October 1997 on 42 dairy farms located in Addis Ababa, Sebeta, Kaliti and Debre Zeit, Ethiopia. An overall herd infection rate of 33.3 percent was established. With respect to the production systems, 100 percent, 30 percent...

In animal production systems, the value of a species increases in relation to its adaptation, capacity to make socioeconomic contributions, capacity to fill market opportunities, and potential for increasing productivity. In the case of goats, their role and potential contribution to increased pr...

This paper reviews the past contributions of epidemiology and economics to the control of tick-borne infections of cattle in Africa. The factors affecting successful and unsuccessful control are evaluated on a gographical and on a production systems basis, with particular reference to Theileria p...
