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 identify the target population of cattle for immunisation against East Coast fever (ECF) using the infection-and-treatment method. Firstly, a sentinel-calf study was used to determine the age window for ECF immunisation by determining ages at clinical detection...

Factors influencing reproductive performance in a range of network situations
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...

An individual animal model was fitted to data from a crossbred herd in the lowland coastal tropics of Kenya to estimated breed cross means for a total of 25 genotypes having different proportions of Ayrshire (A), Brown Swiss (B), Friesian (F) and Sahiwal (S) genes. These means were then regressed...
