Effect of moisture supply, maturity and supplementation with soyabean meal on digestibility of Napier grass fed to sheep
Muia, JMK; Tamminga, S; Mbugua, PN; Kariuki, JN (University of NairobiCollege of Agriculture and Veterinary Sciences, 2001)In Naivasha (1940-m altitude), Kenya, the digestibility of Napier grass (var. Bana) was determined from the 3rd to 15th week of growth under 2 watering regimes which simulated the medium (800 mm) and high (1200 mm) rainfall ... -
Effect of supplementing napier grass (Pennisetum purpureum) with sunflower meal or poultry litter-based concentrates on feed intake, live-weight changes and economics of milk production in Friesian cows
Muia, J.M.K; Tamminga, S; Mbugua, P.N (National Animal Husbandry Research Centre, Naivasha, KenyaWageningen Agricultural University, Institute of Animal Sciences, Wageningen, The NetherlandsUniversity of Nairobi, Department of Animal Production, Nairobi, Kenya, 2000)A study was conducted using a randomized complete block design to determine feed intake, live-weight changes, milk yield and cost of milk production in Friesian cows fed napier grass (NG) at 10 weeks (MNG) or 15 weeks (ONG) ... -
Feeding Behaviour of Sahiwal and Friesian Cattle Under a Zero Grazing System in a Tropical Climate
Kariuki, J N; Tamminga, S; Gachuiri, C K; Gitau, G K; Muia, J M K (1999-03)A study was conducted in a tropical environment in Kenya, to determine the feeding behaviour of Friesian and Sahiwal cattle fed on napier grass (Penni.setum purpureum) under zero grazing conditions. Measurements were ... -
Intake and rumen degradation in cattle fed napier grass iPennisetum purpureum) supplemented with various levels of Desmodium intortum and Ipomoea batatus vines
Kariuki, J N; Tamminga, S; Gachuiri, C K; Gitau, G K; Muia, J M K (South African Society of Animal ScienceDepartment of Animal Production, 2001)This study was conducted to assess the effect of greenleaf desmodium (Desmodium intortum) and sweet potato vine (Ipomoea batatus) supplementation of napier grass on dry matter intake, degradation and rumen fermentation ... -

Optimal stage of maturity for feeding napier grass (Pennistetum purpureum) to dairy cows in Kenya
Muia, J. M. K; Tamminga, S; Mbugua, P. N; Kariuki, J. N (Kenya Agricultural Research Institute, National Animal Husbandry Research Centre, Naivasha, KenyaInstitute of Animal Sciences, Wageningen Agricultural University, The NetherlandsDepartment of Animal Production, University of Nairobi, Kenya, 1999)Two experiments were conducted to determine the maturity at which napier grass (Pennisetum purpureum var. Bana) should be fed to dairy cows in Kenya. The grass was grown in two fields and irrigated to simulate precipitation ... -
Prediction of yield and digestibility of Napier grass (Pennisetum purpureum) from maturity, leaf: stem ratio and laboratory analyses
Muia, J. M. K; Tamminga, S; Mbugua, P. N; Kariuki, J. N (2000)Napier grass (P. purpureum) was grown at Naivasha, Kenya. Weekly data on various parameters of Napier grass on-station (irrigated) and on-farm (rain-fed) were pooled and assessed by linear and quadratic regressions. The ... -
Rumen degradation and estimation of microbial protein yield and intestinal digestion of napier grass (Pennisetum purpureum) and various concentrates
Muia, J.M.K; Tamminga, S; Mbugua, P.N; Kariuki, J.N (National Animal Husbandry Research Centre, Naivasha, KenyaInstitute of Animal Sciences, Wageningen Agricultural University, Wageningen, The NetherlandsDepartment of Animal Production, University of Nairobi, Nairobi, Kenya, 2001)A study was conducted in a repeated measure arrangement using four rumen fistulated steers to determine degradation of napier grass (Pennisetum purpureum), protein ingredients and concentrates. Cotton seed cake (CSC), ... -
