Histopathological Evaluation of Spleen, Liver and Kidneys from Pigs Fed on Moringa oleifera Leaf Meal Diets
(University of Nairobi, 2017)Moringa oleifera leaves and seeds have for a long time been used as food and medicine. Despite increased usage, little information is available on its application as a nutraceutical agent as well as toxicity. The objective ... -
Growth performance, feed conversion efficiency and blood characteristics of growing pigs fed on different levels of Moringa oleifera leaf meal
(University of Nairobi, 2017)To determine the effects of inclusion, at different levels of Moringa oleifera leaf meal (MOLM) in growing pig diets on pig’s daily feed intakes (DFI), growth performance, feed conversion efficiency (FCE), haematology ... -
Seroepidemiological Survey of Rift Valley Fever Virus in Ruminants in Garissa, Kenya
(University of Nairobi, 2017)Introduction: Rift Valley fever (RVF) is a vector-borne zoonotic disease caused by phlebovirus in the family Bunyaviridae. In Kenya, major outbreaks occurred in 1997–1998 and 2006–2007 leading to human deaths, huge economic ... -
Regeneration-Competent and -Incompetent Murids Differ in Neutrophil Quantity and Function
(University of Nairobi, 2019)Regeneration is rare in mammals, but spiny mice (Acomys spp.) naturally regenerate skin and ear holes. Inflammation is thought to inhibit regeneration during wound healing, but aspects of inflammation contribute to both ... -
Evaluation of Potato (Solanum tuberosum L.) Nutrient Use Efficiency under Legume Intercropping Systems
(University of Nairobi, 2016)A field study was carried out to assess the effect of potato - legume intercropping on a number of nutrient use efficiency indices, i.e. nitrogen use efficiency (NUE), nitrogen uptake efficiency (NUpE) and nitrogen harvest ... -
To Assess the Age of Giving Complementary Feeding to Infants before Six Months and Reasons Given and the Nutritional Status of Lactating Mothers of Mwanamukia Area- Nairobi
(University of Nairobi, 2016)Exclusive breastfeeding with appropriate complementary feeding can save infants from many problems later in life. The study found that majority of respondents were married (63.9%), single (25.5%). 43.1% had primary ... -
Effect of rangeland rehabilitation on the herbaceous species composition and diversity in Suswa catchment, Narok County, Kenya
(University of Nairobi, 2017)Introduction: Land degradation is a serious environmental problem of our time. In Kenya, it is estimated that 30% of the total land mass is severely degraded. Suswa catchment within Narok County is a good example with ... -
Effects of Land Use and Land Cover changes on Soil Organic Carbon and Total Nitrogen Stocks in the Olesharo Catchment, Narok County, Kenya
(University of Nairobi, 2018)Land Use and Land Cover Change (LULCC) is the most prominent cause of Soil Organic Carbon (SOC) variability in any landscape. Kenyan Arid and Semi-Arid Lands (ASALs) have been facing extensive land use/ cover changes in ... -
Pasture enclosures increase soil carbon dioxide flux rate in Semiarid Rangeland, Kenya
(University of Nairobi, 2018)Background Pasture enclosures play an important role in rehabilitating the degraded soils and vegetation, and may also influence the emission of key greenhouse gasses (GHGs) from the soil. However, no study in East Africa ... -
Enhancing soil organic carbon, particulate organic carbon and microbial biomass in semi-arid rangeland using pasture enclosures
(University of Nairobi, 2018)Background Rehabilitation of degraded rangelands through the establishment of enclosures (fencing grazing lands) is believed to improve soil quality and livelihoods, and enhance the sustainability of rangelands. Grazing ... -
Plant Extracts And Antagonistic Fungi As Alternatives To Synthetic Pesticides In Management Of Fungal Diseases Of Tomato
(University of Nairobi, 2016)Incorporation of biological pesticides in integrated pest management has lately been considered effective in production of safe food for human consumption, aesthetically valuable for the prime markets and increase in crop ... -
Biopesticide-based IPM systems to reduce synthetic pesticide residues in vegetables for niche market access by small holder growers
(University of Nairobi, 2016)In the last few decades, farmers have relied on synthetic pesticides to managed crop pests and diseases. This is because synthetic pesticides are easily available, have quick knock down effect, have varied modes of action ... -
Short-term dynamics of soil organic matter fractions and microbial activity in smallholder potato-legume intercropping systems
(University of Nairobi, 2019)Continuous cultivation of potato (Solanum tuberosum L.) in monoculture systems represents the greatest factor deteriorating soil organic matter (SOM) in smallholder farms. With an aim to breaking this norm, a 2-year field ... -
Controlling soil erosion in smallholder potato farming systems using legume intercrops
(University of Nairobi, 2019)Competition for nitrogen (N) and phosphorous (P) under potato-based intercropping systems decreases the level of nutrients available for potato and subsequently influences nitrogen and phosphorous use efficiency. A field ... -
Nitrogen and phosphorous uptake by potato (Solanum tuberosum L.) and their use efficiency under potato-legume intercropping systems
(University of Nairobi, 2018)Competition for nitrogen (N) and phosphorous (P) under potato-based intercropping systems decreases the level of nutrients available for potato and subsequently influences nitrogen and phosphorous use efficiency. A field ... -
Optimizing yield and economic returns of rain-fed potato ( Solanum tuberosum L.) through water conservation under potato-legume intercropping systems
(University of Nairobi, 2018)Even though potato (Solanum tuberosum L.)-based intercropping systems are widely practised in developing countries, only a few studies have focused on legumes as the companion intercrops. This study was conducted to assess ... -
Potato-legume intercropping on a sloping terrain and its effects on soil physico-chemical properties
(University of Nairobi, 2019)Aims To assess the effects of potato-legume intercropping on selected soil physical and chemical properties after four consecutive growing seasons (from the short rains in 2014 to long rains 2016). Methods The experiment ... -
Combining Ability for Drought Tolerance in Upland Rice Varieties at Reproductive Stage
(University of Nairobi, 2017)Rice is an important food crop for human population ranking second among the mostly consumed cereal grains worldwide. Upland rice production is greatly constrained by drought stress resulting from rainfall variation patterns. ... -
