A total of 1443 records of preweaning traits of calves in a dairy herd in coastal lowland Kenya were used to estimate crossbreeding parameters in a regression analysis. In this herd, the Ayrshire (A), Brown Swiss (B) and Sahiwal (S) breeds have been used in a 3-breed rotation crossbreeding system...

Dairy cattle are an important component of farming systems in highland areas of East Africa where they are combined with food an cash crops. The farms are characterised by decreasing size and a small proportion of land used for forage production. Under such conditions only small herds can be main...

Isometamidium chloride is the most important chemoprophylactic agent used in the control of African bovine trypanosomiasis, although breakdowns in prophylaxis have been observed in the field. It is not usually apparent whether these breakdowns are due to inadequate drug dosage regimens, or to the...

Smallholder dairy production based on zero-grazed Napier grass (Pennisetum purpureum CV Bana) fed to crossbred Bos taurus X Bos indicus cows has been introduced to tropical sub-humid East Africa. Leucaena leucocephala forage offers a cheap convenient source of supplementry protein. Thirty-six Ayr...
