Crossbreeding parameters and variance components were estimated for lactation and reproductive traits of crosses between the Sahiwal, Brown Swiss and Ayrshire breeds in a dairy herd in sub-humid coastal Kenya. An individual animal model was fitted to the data with a fixed effect for 20 distinct b...
Two experiments with 12 and 18 lactating Jersey cows respectively were carried out in the coastal semi-humid zone of Kenya to assess the performance arising from the feeding of chopped Napier fodder (Pennisetum purpureum) given ad libitum with and without one of three sources of protein; fishmeal...
Since 1989, a step-wise series of farming systems surveys and epidemiological studies have been carried out in coastal Kenya to identify and resolve major disease constraints affecting smallholder dairy production. This paper describes the sequential studies and reports on the significance of, an...
The predicted performance of nine crossbreeding strategies for milk production and reproductive traits and cow live weights (LW) were compared. The strategies were selected because of their superiority to many others. The data were from crosses of Ayrshire (A), Brown Swiss (B), Friesian (F) and S...
Large increases in demand for milk and dairy products in developing countries are projected for the next 25 years. These represent exciting market opportunities for smallholders, such as those in Kenya, which has over 85% of the dairy cattle population in eastern Africa. Currently Kenya’s per ca...
Crossbreeding parameters for milk production and reproductive traits and for cow live weight (LW) of crosses of Ayrshire (A), Brown Swiss (B), Friesian (F) and Sahiwal (S) cattle were estimated using data from a dairy herd in the lowland coastal tropics of Kenya. An individual animal model was fi...
Details the voluntary food intake, live-weight change and lactation performance of 36 crossbred Ayrshire/Brown Swiss X Sahiwal cows fed from the 3rd week of lactation for 14 weeks on diets of napier fodder offered ad libitum and supplemented w. fresh leucaena fodder. Average daily milk yield duri...
An account is given of the Development of dairy farming, milk production and stocking rate of cattle in Kenya, Gambia, Nigeria, Zimbabwe, Tanzania and Guinea-Bissau and the relevance of the African experience for sustainable small-scale agriculture in other tropical countries.
