The objectives of this study were to explore the possibilities for improving the breeding practices and developing policies in support of smallholder dairy producers in the central highlands of Kenya through analysing current disposal and replacement practices. Data were obtained from a cross-sec...

The biological productivity of cow-calf units in low-input production systems in tropical Africa is reviewed. Four production systems (pastoralists agropastoralists, crop-livestock farmers and smallholder farmers) are identified. Fifty-five data sets from monitoring and systems research conducted...

A total of 1443 records of preweaning traits of calves in a dairy herd in coastal lowland Kenya were used to estimate crossbreeding parameters in a regression analysis. In this herd, the Ayrshire (A), Brown Swiss (B) and Sahiwal (S) breeds have been used in a 3-breed rotation crossbreeding system...

Presents preliminary results of a study of N'Dama cattle introduced in a metayage system in Zaire. Studies tsetse relative densities, tsetse challenge, corrected tsetse challenge, trypanosome prevalence and PCV in gallery forest, savanna woodland and grass savanna areas. Also presents data on fee...

Dairy cattle are an important component of farming systems in highland areas of East Africa where they are combined with food an cash crops. The farms are characterised by decreasing size and a small proportion of land used for forage production. Under such conditions only small herds can be main...

The Kenya coastal region has a large, unsatisfied market for milk and dairy products. Between 1988 and 1994, a research project, closely linked to extension, identified and addressed technical constraints that limit smallholder dairy Development in the region. Methodological approaches are outlin...

Large increases in demand for milk and dairy products projected for the next 25 years represent exciting market opportunities for smallholders in eastern Africa. With the exception of Kenya, traditional cattle production systems based on indigenous breeds dominate milk production in the region, y...
