A rural poultry production manual
(1998): Indigenous chickens in Kenya are about 22 million and are kept by 90% of the rural communities in small flocks of up to 30 birds mainly under free range system. The industry is flexible and does not require a lot of ... -
Biodegradation of carbofuran in soils within Nzoia River Basin, Kenya
(Journal of Environmental Science and Health, 2015-04-06)Carbofuran (2,3-dihydro-2,2-dimethylbenzofuran-7-yl methylcarbamate) has been used within the Nzoia River Basin (NRB), especially in Bunyala Rice Irrigation Schemes, in Kenya for the control of pests. In this study, the ... -
Evaluating characteristics of indigenous chicken system with flock size trends in a participatory research on improved management practices in Kenya
(2015)Analysis and evaluation of agricultural systems use these criteria: energy, economic, agronomy, environmental conservation and time. Because of time importance indicator for reducing timeliness cost, project scheduling ... -
Antimicrobial Coumarins from the Oyster Culinary-Medicinal Mushroom, Pleurotus ostreatus (Agaricomycetes), from Kenya
(International Journal of Medicinal Mushrooms, 2016-01-01)Pleurotus ostreatus has been widely used as food because of its nutritional and medicinal properties. These have been attributed to the presence of macronutrients, minerals, vitamins, and amino acids, among other secondary ... -
Evaluating interventions uptake in indigenous chicken production in a participatory research with smallholder farmers in Kenya
(2015)Indigenous chicken production system has long been characterised by low productivity due to among other factors, poor management, inadequate and poor feeding regime, poor (or lack) of disease control measures, poor hygiene, ... -
Changes in lipids utilisation during moisture and temperature stress of infective (L3) and its implication on the epidemiology of Haemonchus contortus in arid and semi arid lands
(Maxwell science publishing, 2011-03-05)A study was undertaken to establish the pattern and level of lipid utilization in third stage infective larvae (L_3) of Haemonchus contortus under temperature and moisture stress conditions. The stress factors were ... -
Seroprevalence of chikungunya infection in pyretic children seeking treatment in Alupe district hospital, Busia county Kenya
(2013)Chikungunya fever is a viral disease transmitted to humans majorly by a bite of infected Aedes aegypti mosquitoes. Studies have revealed that other species of Aedes mosquitoes equally transmit chikungunya virus (CHIKV). ... -
Investigating eggs hatchability in indigenous chicken system with smallholder farms in Kenya in a participatory research using analysis of variation
(Elewa bioSciences, 2014)Objective: The aim of this farmer participatory research was to investigate the treatment effects of housing, vaccination, deworming and feed supplementation on production characteristics of indigenous chicken in different ... -
Dynamic risk model for rift valley fever outbreaks in Kenya based on climate and disease outbreak data
(Geospatial health, 2016-05-31)Rift Valley fever (RVF) is a mosquito-borne viral zoonotic disease that occurs throughout sub-Saharan Africa, Egypt and the Arabian Peninsula, with heavy impact in affected countries. Outbreaks are episodic and related to ... -
Stress response in infective larvae (L3) of the parasitic nematode haemonchus Contortus is accompanied by enhanced expression of heat shock proteins (HSP 70)
(Maxwell science, 2012-07-10)The study was undertaken to investigate the effects of temperature and moisture stresses on protein profile and characteristics in the free living third larval stages (L_3) of Haemonchus contortus. Before and after temperature ... -
Exsheathment characteristics and infectivity of revived anhydrobiotic L_ (3) of haemonchus contortus
(Maxwell science, 2012-10-20)This study was conducted to determine the effect of temperature and moisture stress on exsheathment process and infectivity of the infective larvae of the parasitic nematode "Haemonchus contortus". Laboratory conditions ... -
Stochastic drought forecasting exploration for water resources management in the upper Tana river basin, Kenya
(IGI Global, 2016)This chapter presents the trend of drought as a stochastic natural disaster influenced by the climate variability for the upper Tana River basin in Kenya. Drought frequency, duration and intensity in the upper Tana River ... -
Detection of spatial, temporal and trend of meteorological drought using standardized precipitation index (spi) and effective drought index (edi) in the upper Tana river basin.
(Scientific Research Publishing, 2018-07-17)Drought events across the world are increasingly becoming a critical problem owing to its negative effects on water resources. There is need to understand on-site drought characteristics for the purpose of planning mitigation ... -
Evidence of hydrological extremes primarily driven by human land use changes in tropical African basins
(2018-04)The sensitivity of basins to human alterations on land and their associated hydrological impacts is a subject of on-going research and is particularly poorly understood especially in tropical African basins. Oftentimes ... -
Simulation of the hydraulics and treatment performance of horizontal subsurface flow constructed wetland treating greywater
