An experiment was carried out to evaluate dairy performance and rumen fermentation from a forage-based diet supplemented with Leucaena leucocephala (leucaena) and maize bran. Bos indicus (Ayrshire/Brown Swiss) X Bos taurus (Sahiwal) cattle were offered Pennisetum purpureum (napier grass) ad libit...

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...

Smallholder dairy development in coastal lowland Kenya is mainly constrained by inadequate nutrition. Since the early 1960s, high quality forages have been introduced to improve feeding of dairy cattle in the region. A study was conducted to assess the contribution made by these forages to dairy ...

This study uses heteroskedastic Tobit and Censored Least Absolute Deviations models to examine the impacts of dairy cow ownership on selected outcomes for a sample of 184 households in coastal Kenya. The outcomes examined include gross household cash income, gross non-agricultural income, consump...

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...

Bana) supplemented with leucaena forage in the lowland semi-humid tropics

Twenty intact and five fistulated crossbred steers were used in two experiments to examine the effect of supplementing maize stover with Gliricidia sepium or Leucaena leucocephala forage on intake, rumen fermentation, microbial protein supply and live weight changes. The basal diet plus 1 kg maiz...

Two experiments were carried out to evaluate the effect of incremental levels of Gliricidia sepium (gliricidia) and Leucaena leucocephala (leucaena) on forage intake, diet apparent digestibility, microbial nitrogen supply and live-weight changes in cattle. In each experiment, 20 intact and five f...

This study examines the factors influencing adoption of three related dairy technologies in coastal Kenya, and assesse the impacts of dairy adoption on household income, employment generation and nutritional status of pre-school children. The technologies studied were adoption of grade and crossb...

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...
