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

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

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...


Mureithi, J.G.Taylor, R.S.Thorpe, W.R.[Productivity of alley farming with leucaena (Leucaena leucocephala Lam. de Wit) and Napier grass (Pennisetum purpureum K. Schum) in coastal lowland Kenya]Productivity of alley farming with leucaena (Leucaena leucocephala Lam. de Wit) and Napier grass (Pennisetum purpureum K. Schum) in coastal lowland Kenya

Since 1989, a step-wise series of farming systems surveys and epidemiological studies have been carried out in coastal Kenya to identify and resolve major disease constraints affecting smallholder dairy production. This paper describes the sequential studies and reports on the significance of, an...


Maloo, S.H.Thorpe, W.R.Ngumi, P.N.Perry, Brian D.[Systematic epidemiological studies to identify and resolve health constraints to smallholder dairy production in coastal lowland Kenya]Systematic epidemiological studies to identify and resolve health constraints to smallholder dairy production in coastal lowland Kenya

A total of 1443 records were used to estimate individual and maternal additive genetic breed and heterotic effects for preweaning growth and survival traits of crosses of Ayrshire (A), Brown Swiss (B), and Sahiwal (S) in a dairy herd in the lowland coastal tropics of Kenya. Individual and matern...


Kahi, A.K.Mackinnon, M.J.Thorpe, W.R.Baker, R.L.Njubi, D.[Estimation of individual and maternal additive genetic and heterotic effects for preweaning traits of crosses of Ayrshire, Brown Swiss and Sahiwal cattle in the lowland tropics of Kenya]Estimation of individual and maternal additive genetic and heterotic effects for preweaning traits of crosses of Ayrshire, Brown Swiss and Sahiwal cattle in the lowland tropics of Kenya

This study aimed at better understanding of the characteristics of feeding and breeding practices smallholder farmers adopt in intensifying their dairy production. Use of hired labour for fodder gathering, growing of fodder crops and purchase of feeds increased with increasing intensification, bu...


Bebe, B.O.Udo, H.M.J.Thorpe, W.R.[Characteristics of feeding and breeding practices for intensification of smallholder dairy systems in the Kenya highlands]Characteristics of feeding and breeding practices for intensification of smallholder dairy systems in the Kenya highlands

A cross-sectional study was carried out from July to September 1989 in Kaloleni Division, Coast Province, Kenya to estimate the prevalence of vector-transmitted diseases in small-holder dairy cattle and to identify the risk factors associated with different management systems. One hundred and thi...


Maloo, S.H.Thorpe, W.R.Kiio, G.Ngumi, P.Rowlands, G.J.Perry, Brian D.[Seroprevalences of vector-transmitted infections of small-holder dairy cattle in coastal Kenya]Seroprevalences of vector-transmitted infections of small-holder dairy cattle in coastal Kenya

Details the voluntary food intake, live-weight change and lactation performance of 36 crossbred Ayrshire/Brown Swiss X Sahiwal cows fed from the 3rd week of lactation for 14 weeks on diets of napier fodder offered ad libitum and supplemented w. fresh leucaena fodder. Average daily milk yield duri...


Muinga, R.W.Thorpe, W.R.Topps, J.H.[Voluntary food intake, live-weight change and lactation performance of crossbred dairy cows given ad libitum Pennisetum purpureum (napier grass var. Bana) supplemented with leucaena forage in the lowland semi-humid tropics]Voluntary food intake, live-weight change and lactation performance of crossbred dairy cows given ad libitum Pennisetum purpureum (napier grass var. Bana) supplemented with leucaena forage in the lowland semi-humid tropics

Data on accumulated life performance of crosses of Ayrshire (A), Brown Swiss (B), Friesian (F) and Sahiwal (S) cattle collected over a 21- years period from a dairy ranch in the lowland tropics of Kenya were analysed to estimate additive and non-additive genetic effects of economic traits. These ...
