Kahi, A.K.Thorpe, W.R.Baker, L.[Estimates of heritabilities and genetic and phenotypic correlations for preweaning traits of calves in a crossbred dairy herd in coastal lowland Kenya]Estimates of heritabilities and genetic and phenotypic correlations for preweaning traits of calves in a crossbred dairy herd in coastal lowland Kenya

Records from 1577 cows borm from 1973 to 1983 on a ranch in lowland Kenya were analyzed for age at first calving, lactation length, lactational milk yield, calving interval, annual milk yield, and, for cows born from 1973 to 1979, number of calvings, productive lifetime in the herd, and lifetime ...


Thorpe, W.R.Morris, C.A.Kang'ethe, P.[Crossbreeding of Ayrshire, Brown Swiss, and Sahiwal cattle for annual and lifetime milk yield in the lowland tropics of Kenya]Crossbreeding of Ayrshire, Brown Swiss, and Sahiwal cattle for annual and lifetime milk yield in the lowland tropics of Kenya

The role of livestock in nitrogen cycling in mixed crop-livestock farming systems of sub-Saharan Africa was explored. Cattle were fed a range of diets to investigate the effects on partitioning of nitrogen between urine and faeces and on the chemical composition of the manures produced. The trade...


Delve, Robert J.Cadisch, GeorgTanner, J.C.Thorpe, W.R.Thorne, Peter J.Giller, Ken E.[Implications of livestock feeding management on soil fertility in the smallholder farming systems of sub-Saharan Africa]Implications of livestock feeding management on soil fertility in the smallholder farming systems of sub-Saharan Africa

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 ...

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...


Ogore, P.B.Baker, R.L.Kenyanjui, M.Thorpe, W.R.[Assessment of natural ixodid tick infestations in sheep]Assessment of natural ixodid tick infestations in sheep

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...


Muinga, R.W.Topps, J.H.Rooke, J.A.Thorpe, W.R.[The effect of supplementation with Leucaena leucocephala and maize bran on voluntary food intake, digestibility, live weight and milk yield of Bos indicus X Bos taurus dairy cows and rumen fermentation in steers offered Pennisetum purpureum ad libitum in the semi-humid tropics]The effect of supplementation with Leucaena leucocephala and maize bran on voluntary food intake, digestibility, live weight and milk yield of Bos indicus X Bos taurus dairy cows and rumen fermentation in steers offered Pennisetum purpureum ad libitum in the semi-humid tropics

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...


Baker, R.L.Mugambi, J.M.M.Audho, James O.Carles, A.B.Thorpe, W.R.[Genotype by environment interactions for productivity and resistance to gastro-intestinal nematode parasites in Red Maasai and Dorper sheep]Genotype by environment interactions for productivity and resistance to gastro-intestinal nematode parasites in Red Maasai and Dorper sheep

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...

Omore, Amos O.McDermott, John J.Muriuki, H.M.Thorpe, W.R.[Smallholder dairy herd management in Kenya]Smallholder dairy herd management in Kenya

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...
