The objective of this study was to quantify the rate of genetic progress in 305-d milk yield (MY) in Bos taurus dairy cattle breeds. The Bos taurus breeds considered were Holstein Friesian (F), Ayrshire (A), Jersey (J) and ...
Beef production in the arid and semi-arid lands of Kenya: constraints and prospects for research and development
(SAGE Publications, 2006-09)
Most of Kenya (80%) is classified as arid and semi-arid. The climatic conditions in these regions are so harsh for crops that only livestock production can thrive. These regions provide the bulk of beef consumed in the ...

Participatory selection of sweet potato (Ipomoea batatas (L.) Lam.) cultivars using mother and baby trial in Western Kenya
(ISHS Acta Horticulturae 911, 2009-08-31)
Sweet potato (Ipomoea batatas (L.) Lam) is a drought tolerant food security crop. Western Kenya accounts for 60% of the national production. Intensive production is constrained by lack of improved high yielding cultivars ...
