Lekasi, J.K.Tanner, J.C.Kimani, S.K.Harris, P.J.C.[Manure management strategies to enhance fertilizer quantity and quality as smallholdings in central Kenya highlands]Manure management strategies to enhance fertilizer quantity and quality as smallholdings in central Kenya highlands

N'Dama heifers, initially weighing 129 kg at approximately 30 months of age, were supplemented with 250, 500 or 1000g/head/day groundnut cake for 3 or 6 months during the dry or dry and wet seasons. Highly significant improvements in rates of liveweight gain and reproductive performance were obta...


Tanner, J.C.Little, D.A.Holden, S.J.Dampha, K.[Reducing age at first calving in N'Dama heifers using groundnut cake as a supplement to grazed natural pasture in The Gambia]Reducing age at first calving in N'Dama heifers using groundnut cake as a supplement to grazed natural pasture in The Gambia

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

Concentrate feeds have become an important feature of dairy cattle diets on small-scale farms in the Central Kenya Highlands. Excreta derived from such diets can be of high quality if nutrient losses are minimized. Steers were fed a basal diet of Napier grass supplemented with either commercial d...


Lekasi, J.K.Tanner, J.C.Kimani, S.K.Harris, P.J.C.[Effects of poultry litter amended steer diets and subsequent manure collecting systems on nutrient recovery in composted manures]Effects of poultry litter amended steer diets and subsequent manure collecting systems on nutrient recovery in composted manures

Information is needed on the biophysical and economic rationale for labour-demanding (and therefore, expensive) backyard animal rearing systems on smallholdings in the uplands of Java where livestock have been an integral part of highly intensive agriculture for centuries. The occurrence of high ...


Tanner, J.C.Holden, S.J.Owen, E.Winugroho, M.Gill, M.[Livestock sustaining intensive smallholder crop production through traditional feeding practices for generating high quality manure-compost in upland Java]Livestock sustaining intensive smallholder crop production through traditional feeding practices for generating high quality manure-compost in upland Java

Twelve Boran steers with a mean live weight of 215.8 ± 13.9 kg were used in an incomplete Latin Square experiment to compare the apparent phosphorus (P) absorption in cattle when Napier grass (Pennisetum purpureum) was supplemented with Busumbu rock phosphate (BRP), Minjingu rock phosphate (MRP)...


Odongo, N.E.Tanner, J.C.Romney, D.L.Plaizier, J.Straaten, P. vanMcBride, B.[The effects of supplementing Napier grass (Pennisetum purpureum) with rock phosphate and steamed bone meal compared with a commercial mineral mix on phosphorus absorption in cattle]The effects of supplementing Napier grass (Pennisetum purpureum) with rock phosphate and steamed bone meal compared with a commercial mineral mix on phosphorus absorption in cattle

Three hundred mixed, smallholder farms in Kariti location, Kandara Division, Maragua District, Central Kenya, were surveyed. Dairy cattle management practices, including type of animal enclosure, roofing, floor type, drainage, use of bedding, feeding of concentrates; and manure management pract...


Lekasi, J.K.Tanner, J.C.Kimani, S.K.Harris, P.J.C.[Cattle manure quality in Maragua District, central Kenya: Effect of management practices and development of simple methods of assessment]Cattle manure quality in Maragua District, central Kenya: Effect of management practices and development of simple methods of assessment

Exmines the nutritive value of fruits from Acacia tortilis, A. albida, A. nilotica and A. sieberiana. Compares the fruits of these four species with the meal produced by industrial extraction of oil from noug (Guizotia abyssinica). Also compares these feeds as sources of protein when offered in c...


Tanner, J.C.Reed, J.D.Owen, E.[The nutritive value of fruits (pods with seeds) from four acacia spcompared with extracted noug (Guizotia abyssinica) meal as supplements to maize stover for Ethiopian highland sheep]The nutritive value of fruits (pods with seeds) from four acacia spcompared with extracted noug (Guizotia abyssinica) meal as supplements to maize stover for Ethiopian highland sheep

Maize was planted at two, three or four seeds per hole with uniform spacing and either the smallest plant (S) or the second largest plant (L) was thinned from each hole after 8 and 14 weeks from the four seed plots and after 14 weeks for the three seed plots. Two plants per hole were left to matu...


Methu, J.N.Owen, E.Tanner, J.C.Abate, A.L.[The effect of increasing planting density and thinning on forage and grain yield of maize in Kenyan smallholdings]The effect of increasing planting density and thinning on forage and grain yield of maize in Kenyan smallholdings

Presents and discusses ILCA's research approach on the development of sustainable feeding systems for increasing small ruminant production on smallholder farms. Examines in detail the three levels of interrelated research activities, viz, strategic research, commodity research and on-farm develop...


Reed, J.D.Ebong, CyprianTanner, J.C.Gebru, G.Akalework, N.[The nutritive value and use of feeds for fattening small ruminants in African highlands: A perspective of ILCA's research]The nutritive value and use of feeds for fattening small ruminants in African highlands: A perspective of ILCA's research
