Genetic Relationship between Lactation Curve Traits in Dairy Cattle
(2010)Dairy cattle selection strategy in Kenya prefers cows with good 305-day lactation milk yield (TMY) in previous parity. This has improved milk production although increased incidences of physiological disorders and ... -
Genetic relationship between lactation curve traits in the first three parities of dairy cattle
(2014-10-07)In Kenya, selection of dams for the national contract mating scheme is based on 305-day lactation milk yield (TMY) performance across parities. At farm level, only cows that had good TMY performance in previous parity are ... -
Genetic variability in registered Alpine dairy goat population in Kenya
(Ruforum, 2021)A total of 6893 individuals were used to evaluate the population structure and genetic variability of registered Alpine dairy goats in Kenya. Parameters estimated were pedigree completeness, maximum generations traced, ... -
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 (eg, milk yield) and those that are more difficult ... -
GOAT BREEDING IN LOW INPUT PRODUCTION SYSTEMS: INTERGRATING VALUES AND MODERN BREEDING TECHNOLOGIES FOR IMPROVING INSTRINSIC ROBUSTNESS
(2012-09)Low input production systems operate on long term values of supporting stable livestock production through efficient and sustainable combination of various production resources to achieve the desired production objectives. ... -
In vitro organic matter disappearance of tanniferous browse using rumen liquid from goats ingesting grass versus browse
(Taylor & Francis, 2013-12-01)In vitro organic matter disappearance (IVOMD) of African browse species often indicates artificially low nutritive value due to the presence of condensed tannins (CT). Diet of the rumen liquor donor may change this if it ... -
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 ... -
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 ... -
Non-genetic sources of variation and temporal variability in growth and feed efficiency traits among phylogenetically distinct clusters of indigenous chicken in Kenya
(Springer Netherlands, 2016-12-01)This study aims to investigate the influence of non-genetic factors on feed efficiency in indigenous chicken. Residual feed intake (RFI), residual gain (RG) and residual intake and gain (RIG) were used as measures of ... -
NON-GENETIC SOURCES OF VARIATION IN LACTATION CURVE TRAITS OF DAIRY CATTLE IN KENYA
(2010)Lactation curves are a graphical representation of the milk production profile of a cow from parturition to drying up. They provide information about the productivity of the cow and offer a means of explaining features ... -
Nutritional composition, in vitro gas production and in sacco degradability of processed Croton megalocarpus nuts for ruminant feeding
(Online Journal of Animal and Feed Research, 2021)This study was conducted to evaluate the effects of processed croton nut on chemical composition, in vitro gas production and in sacco degradability. Four forms of croton nut namely: whole nut (WN), peeled nut (PN), ... -
Nutritional Value of German Cockroach Meal (Blattela germanica) as a SuperPRO Feed
(Asian Journal of Research in Animal and Veterinary Sciences, 2022-09-22)Evaluating animal feedstuff is a crucial aspect of animal nutrition and formulation. It provides basic nutritional value information on the quality of conventional feedstuffs and enriches the database with novel feedstuffs. ... -
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 ... -
Participatory epidemiological assessment of factors that limit indigenous chicken productivity under free range system in south western Kenya
(Livestock Research for Rural Development P, 2016)This study used participatory epidemiology (PE) tools and laboratory investigations to assess the factor(s) that limit the productivity of the free-ranged indigenous chickens in south western Kenya. The study was conducted ... -

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 ... -
Performance of growing goats fed urea sprayed maize stover and supplemented with graded levels of Tithonia diversifolia
(THE ASIAN-AUSTRALASIAN ASSOCIATION OF ANIMAL, 2017-07-01)A study was carried out to examine the effect of supplementing urea-sprayed maize stover with incremental levels of Tithonia diversifolia (Tithonia) forage on dry matter (DM) intake, digestibility and live weight ... -
Potential of Croton megalocarpus Nut as an Alternative Protein Supplement for Feeding of Ruminants in the Tropics
(University of Kentucky UKknowledge, 2022)Croton megalocarous is a tree native to the arid and semi-arid rangelands of East Africa that produces nuts reported to contain high crude protein (CP). However, they are often neglected as a potential feed due to lack of ... -
Preliminary selection results for body weight in indigenous chicken in Kenya
(2015-04)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. ... -
