The past, present and future genetic improvement of indigenous chicken of Kenya
(Organización de las Naciones Unidas para la Agricultura y la Alimentación (FAO), 2014)Genetic improvement of farm animals encompasses both mating and selection for desired traits and indigenous chicken genetic resources are no exception. In Kenya, previous attempts to genetically improve indigenous chicken ... -
Modelling of lactation curves of dairy cows based on monthly test day milk yield records under inconsistent milk recording scenarios
(Cambridge University Press, 2011-11-01)The objective of this study was to describe the lactation curve of dairy cattle in Kenya using a suitable lactation function in order to facilitate inclusion of partial lactations in national dairy cattle evaluation and ... -
A participatory approach to the evaluation of the efficiency of animal recording practices based on institutional analysis and development framework
(Cambridge University Press, 2011-02-01)Animal recording is an interactive process that involves several practices. The efficiency of the process is essential to ensure the utility of outcomes necessary for sustainable participation. Most evaluation approaches ... -
Preliminary selection results for body weight in indigenous chicken in Kenya
(2015)Body weight at 12 weeks of age records of 443 indigenous chicken, progeny of 44 sires were used to estimate preliminary results of selection for growth in indigenous chicken in Kenya after two generations of selection. ... -
Review of current state of knowledge of microcystin and its impacts on fish in Lake Victoria
(Lakes and reserviors,science,policy and management for sustainable use, 2020-07-03)Microcystins are part of algal toxins produced intracellularly within algal cells, being in the family of hepatotoxic cyclic peptides from various species of blue‐green algae. Blue‐green algae are widely abundant in many ... -
Intensive livestock recording for sustainable breeding programs and adaptation strategy to climate change
(206)The hypothesis that, intensive recording is needed for sustainable breeding programs in developing countries in the face of climate change was tested.Using stochastic simulation, genetic gain realised by breeding strategies ... -
1683 Genome-wide association analysis of residual feed intake and milk yield in dairy goats
(Oxford University Press, 2016-10-01)Interest in both dairy and meat goat production in the US has been increasing, and there is tremendous opportunity for genetic progress in traits that are easy to measure (e.g., milk yield) and those that are more difficult ... -
Variation and Repeatability of Natural Antibodies Against Keyhole Limpet Hemocyanin of Indigenous Chicken of Kenya
(2016-10-21)The immune system is designed to provide protection to the body by combating a plethora of pathogenic micro-organisms. Identifying animals with a natural ability to make superior immune responses reduces disease occurrences, ... -
The prevalence of Cryptosporidium parvum and its relationship to the nutritional status of HIV- positive children suffering from diarrhea in Western Kenya
(Kenya Society of Microbiology, 2005-10-17)In this study, prevalence of Cryptosporidium parvum was studied in relationship to nutrition amongst HIV positive children with diarrhea as a presenting sign. Watery to loose stool and whole blood specimen were collected ... -
Genetic and phenotypic parameters for feed efficiency in indigenous chicken in Kenya
(Elsevier, 2018-01-01)This study aims to determine the genetic and phenotypic parameters of net feed efficiency (NFE) traits namely Residual feed intake (RFI), residual gain (RG), and residual intake and gain (RIG) along the growth curve of ... -
Characterisation of physical egg qualities in indigenous chicken under free range system of production in Western Kenya
(2018)The study was conducted with the aim of characterizing the indigenous chicken (IC) egg production system to determine management practices and how they impact on external egg qualities. Opportunity was taken to identify ... -
Attitude of indigenous chicken farmers towards agricultural insurance in Nyanza, Kenya
(Academic Journals, 2018-05-30)Indigenous chicken (IC) contribute significantly to income and food security of rural communities. However, the IC are kept in systems that are characterised by high risk conditions such as diseases, predation, inadequate ... -
Adaptation of Smallholder Dairy Farmers in South Western Kenya to the Effects of Climate Change
(Scientific Research Publishing, 2019-07-25)Despite great potential, Kenyan smallholder dairying faces diminishing land sizes, high input costs, poor extension contacts, non-responsive price policies, and new pests and diseases. Climate change will worsen the ... -
Dairy goat production in sub-Saharan Africa: current status, constraints and prospects for research and development
(Asian-Australasian Association of Animal Production Societies (AAAP), 2019-08)This paper presents a review of dairy goat production in sub-Saharan Africa (SSA) from 2010–2017, its current state, constraints and prospects for research and development. Since the introduction of dairy goats in SSA in ... -
Multidrug resistance of Salmonella enterica serovars Typhi and Typhimurium isolated from clinical samples at two rural hospitals in Western Kenya
(The journal of infection in developing countries, 2008-04-01)The threat to human health posed by antibiotic resistance is of growing concern. Many commensals and pathogenic organisms have developed resistance to well established and newer antibiotics. This is a cross-sectional study ... -
Effect of Socio-Demographic Characteristics on Kenyan Smallholder Dairy Farmers’ Adaptive Strategies to Climate Change Effects
(Scientific Research Publishing, 2019-09-10)Climate change (CC) impedes smallholder dairy industry in Kenya. Consequently, farmers’ adaptation to CC effects would greatly determine their resilience, profitability, and sustainable contribution to the economy. ... -
Chlorophyll fluorescence, protein and chlorophyll content of three nerica rainfed rice varieties under varying irrigation regimes
(2010)Water deficit affects growth and development of rainfed rice leading to a considerable yield reduction or crop failure. Although the rice crop is susceptible to water deficit, there is a marked genotypic variation in protein ... -
Effects of water deficit on physiology and morphology of three varieties of NERICA rainfed rice (Oryza sativa L.)
(2010)Water deficit is a major problem in rice grown under rainfed conditions. It affects plant growth and development and ultimately leads to a considerable yield reduction or crop failure. Although the rice crop is susceptible ... -
Effects of water deficit on days to maturity and yield of three NERICA rainfed rice varieties
(2010-05)Water deficit is a major problem in rice grown under rainfed conditions. It affects plant growth and development and ultimately leads to a considerable yield reduction or crop failure. Although the rice crop is susceptible ... -
