Competition for milk between calves and pastoral herders may reduce weaning weights, retard growth, and delay puberty in cattle. Calf supplementation could over-ride such effects and improve pastoral economies. To examine these issues in semiarid Ethiopia, 266 Boran calves (Bos indicus) were used...

We carried out a study to assess the risk associated with the presence of Shiga toxigenic Escherichia coli (STEC) in informally marketed unpasteurized milk in urban East Africa. Data for the risk models were obtained from on-going and recently completed studies in Kenya and Uganda. Inputs for the...

An on-farm study was conducted over a 12-year period (1979 through 1990) at four locations in the subhumid zone of Nigeria to estimate levels of performance of Bunaji cattle and to examine factors affecting productivity in these production systems. Average weight at birth, at 9 months and at 12 m...
Milk production in West Africa was investigated. Discussions on the status of production systems and constraints limiting production are included. The need for a strongly co-ordinated research effort in breeding, nutrition, disease, management, and extension education to overcome the problems of ...

The dairy industry needs to be optimised through organising milk production, processing, preservation and marketing in a well-coordinated way. With the recent changes in government policies featured by liberalisation and encouragement of the private sector to participate in the development of alm...
The performance of 40 crossbred calves (Bos taurus, Friesian X Bos indicus, Boran) and 40 Zebu (Boran) calves, from live days after birth to 12 weeks of age, in two separate experiments, was evaluated regarding the effects of two levels of milk (2 or 3 L day-1) and two types of housing (barn (ind...

Recent structural changes in dietary patterns in Asia resulting from economic development are placing increasing pressure on the existing production systems in the region - particularly those systems producing ruminant meat, non-ruminant meat and milk. This has significant policy implications for...

This paper examines the nature and determinants of coordination mechanisms used in the Kenyan fresh milk supply chains, using recent survey data of market participants from Nakuru and Nyandarua districts in Kenya. Three main contractual arrangements are observed in the fresh milk supply chain. Th...
