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. ... -
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, ... -
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 ... -
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. ... -
Determinants of common bean productivity and efficiency: a case of smallholder farmers in eastern Uganda
(2012)Agriculture sustains the livelihoods of about 70.8% of Ugandans, while common bean has emerged to be an important cash crop as well as a staple food for the majority of farmers and consumers. Although Uganda’s bean output ... -
An analysis of economic efficiency in bean production: evidence from Eastern Uganda
(2013)Bean has emerged to be an important cash crop as well as a staple food in Uganda; however, the country’s bean productivity per unit area cultivated has been on the decline for the past ten years. This study estimated ... -
Maize farmers perceptions towards organic soil management practices in Bungoma County, Kenya
(Maxwell Science Publication, 2013)The objective of the study was to evaluate maize farmers’ perceptions towards organic soil management practices in Bungoma County. A simple random sampling technique was used to select a sample of 650 smallholder farmers ... -
Analysis of determinants of productivity and technical efficiency among smallholder common bean farmers in eastern Uganda
(Maxwell Science Publishing, 2013-09-20)The study evaluated factors influencing bean productivity and technical efficiency among smallholder farmers in Eastern Uganda, using a stochastic frontier model and a Tobit model. Findings showed that bean productivity ... -
Disease-resistant GM cassava in Uganda and Kenya during a pandemic
(in 2015 by Banson, 27 Devonshire Road, Cambridge CB1 2BH, 2015)Originating from Latin America, the tuberous root crop cassava is now central to maintaining food security across much of tropical Africa. Cassava has been subject to a succession of pandemics, including cassava mealy bug ... -
Demand for agricultural extension services among small-scale maize farmers: Micro-level evidence from Kenya
(Routledge, 2015-03-15)Purpose: The objective of the study was to determine the level and determinants of demand for extension services among small-scale maize farmers in Kenya. Design/methodology/approach: Based on an exploratory research design, ... -
Economics of Weather Index-based Insurance: Analysis of Smallholder Farmers' Preferences and the Impact of Insurance on Productivity in Kenya
(Goettingen, 2016)Climatic risks are a major challenge for rural communities, especially those whose livelihoods directly depend on agriculture. Weather extremes affect crop productivity not only through the direct relationship between ... -
Weather index insurance, agricultural input use, and crop productivity in Kenya
(GlobalFood Discussion Papers, 2017)Weather risk is a serious issue in the African small farm sector, which will further aggravate due to climate change. Farmers typically react by using low amounts of agricultural inputs. Low input use can help to minimize ...
