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 ...
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 ...
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 ...
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 ...
Genetic evaluation of growth of Dorper sheep in semi-arid Kenya using random regression models
(Elsevier, 2010-10-01)
Data consisting of 8922 weight records from 2642 Dorper sheep from 20 to 380 days of age spanning 1981–1996 were used to model the growth trajectory using random regression (RR) and estimate genetic parameters. The independent ...
Factors that influence the efficiency of beef and dairy cattle recording system in Kenya: A SWOT–AHP analysis
(Springer Netherlands, 2011-01-01)
Animal recording in Kenya is characterised by erratic producer participation and high drop-out rates from the national recording scheme. This study evaluates factors influencing efficiency of beef and dairy cattle recording ...
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 ...
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 ...
VARIANCE COMPONENTS AND GENETIC PARAMETER ESTIMATES UNDER VARYING DEFINITIONS OF CONTEMPORARY GROUPS
(KARI, 2010)
A total of 19 385 test day (TD) milk yield records were used to determine the effect of contemporary group
(CG) on estimates of variance components and genetic parameters for test day milk yield (TMY) data of
Sahiwal ...
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. ...
