Composting cattle manure from zero graziing systems with agro-organic waste to minimise nitrogen losses in smallholder farms in Kenya. Tropical and Subtropical Agro ecosystems 2006 (6)
(University of Nairobi, 2006)
Livestock manure is a valuable source of plant nutrients
for crop production in the Central Kenyan highlands but
its quality in terms of available nitrogen (N) is low due
to considerable N losses through ammonia ...
Genetic variations between indigenous fat-tailed sheep populations in Kenya
(University of Nairobi., 2002)
Sheep are an important source of meat in Kenya. However, there are different sheep types raised in different agro-ecological zones and their genetic status is unknown. This study was designed to establish this. Using samples ...
Independent risk of mechanical ventilation for AIDS-related Pneumocystis carinii pneumonia associated with bronchoalveolar lavage neutrophilia
(University of Nairobi,, 2001)
The use of mechanical ventilation (MV) for AIDS-related Pneumocystis carinii pneumonia (PCP) has varied over time. The introduction of adjunctive corticosteroid therapy has changed the patophysiology of PCP. In the present ...
Continuous sexed dairy F1 production to alleviate poverty: combining the economics and the genetics.
(University of Nairobi., 2007)
We developed an economic model comparing the profitability of Kenyan peri-urban dairy smallholder
production systems for different dairy breeds: purebred Friesians, F1 cows produced by AI, and by
Sexed (female) in vitro ...
Why combine private and communal tree management? A case-study based in Majawanga (Gairo, Tanzania)
(University of Nairobi., 2007)
Despite the focus on the importance of trees in Africa and the many projects that try to improve their management, there is very little research and few development projects which address tree related problems in a holistic ...
Performance and fitness traits versus phenotypic appearance: A novel approach to identify selection criteria for indigenous breeds
(University of Nairobi., 2008)
Ankole cattle are well known for their massive white horns and red coat colour. These characteristics are attributed to centuries of cultural breeding practices. Two experiments with traditional cattle keepers were carried ...
Legume Cover Crops Research In Kenya: Experiences Of The Legume Research Network Project
(KARI, 2003)
The Legume Research Network Project (LRNP) was started in 1994 (by then
known as the Legume Screening Network) to evaluate suitable legume species
for different agro-ecological environments and to subsequently incorporate ...
Potential use of rhizobial bacteria as promoters of plant growth for increased yield in landraces of African cereal crops
(2004)
Rhizobia form root nodules that fix nitrogen (N2) in symbiotic legumes. Extending the ability of these bacteria to fix N2 in non-legumes such as cereals would be a useful technology for increased crop yields among resource-poor ...
The prevalence and economic importance of bovine fasciolosis in Kenya--an analysis of abattoir data
(University of Nairobi, 2002)
A retrospective study covering a period of 10 years (1990-1999) was carried out using post mortem meat inspection records at the Veterinary Department Headquarters at Kabete to determine the prevalence and economic importance ...
Susceptibility of sweetpotato germplasm to rhizopus soft rot caused by Rhizopus stolonifer and Rhizopus oryzae in Kenya
(2003)
Susceptibility of fifteen local and introduced sweetpotato germplasm to Rhizopus soft rot disease caused by Rliizopus stolonifer and Rliitopus oryzae was tested in 1999 and 2000. Roots were surface sterilised, wounded and ...
