Assessment of adult female tick burden was performed on 160,151 and 150 yearling sheep in coastal Kenya at the end of three consecutive infestation periods, respectively. The main attachment sites of fully engorged female ticks were ears, head, body sides, perianal and scrotal/udder regions. Aver...
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...

Red Maasai and Dorper sheep were evaluated for their resistance to gastro-intestinal (GI) nematode parasites (predominantly Haemonchus contortus), productivity and productive efficiency (assessed on a metabolizable energy basis) in experiments undertaken at the Kenyan coast (sub-humid environment...

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...

Ways of promoting integration of herbaceous forage legumes into a napier grass fodder system were evaluated with the aim of increasing forage quantity and quality on smallholder dairy farms in central Kenya. The herbaceous legumes Desmodium intortum cGreenleaf (ILRI 104), Macrotyloma axillare cAx...

The effects of leucaena hedgerows, mulching with leucaena foliage (0.50 and 100 percent of harvested foliage), cowpea intercropping and addition of dairy cattle slurry (55 t ha-1 per maize crop) on the yield of maize from a sandy soil were assessed. The four-year results from five maize crops are...

The effects of alley cropping with Leucaena leucocephala and of different management practices on the productivity of maize and soil chemical properties in lowland coastal Kenya
Inadequate supply of fodder is a serious constraint to the potentially-promising smallholder-dairy production system in coastal Kenya. Alley farming could be an approach to addressing this problem. A study of forage production based on Napier grass and leucaena in an alley cropping system was con...

A cross-sectional stratified random sample survey of 1755 households in the Kenya highlands was conducted between June 1996 and April 1998 to quantify cattle population dynamics in smallholder herds. The free-, semi-zero- and zero-grazing systems practised represented increasing levels of intensi...

Liberalisation in the dairy industry in Kenya is currently under way in several forms. The urban milk market monopoly of the Kenya Co-operative Creameries has been lifted. Clinical veterinary and artificial insemination (AI) services are no longer publicly supported in many areas. Private sector ...
