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 ...
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 ...
Genetic evaluation of milk yield of Bos taurus dairy breeds in Kenya
(2006-11-12)
The objective of this study was to quantify the rate of genetic progress in 305-d milk yield (MY) in Bos taurus dairy cattle breeds. The Bos taurus breeds considered were Holstein Friesian (F), Ayrshire (A), Jersey (J) and ...
Beef production in the arid and semi-arid lands of Kenya: constraints and prospects for research and development
(SAGE Publications, 2006-09)
Most of Kenya (80%) is classified as arid and semi-arid. The climatic conditions in these regions are so harsh for crops that only livestock production can thrive. These regions provide the bulk of beef consumed in the ...
Estimation of maternal covariance components for growth traits in the Sahiwal cattle
(2007)
Maternal influence on growth of artificially reared Sahiwal cattle was investigated using data from the National
Sahiwal Stud (NSS). Growth records on animals born from 1973 to 2004 were used for the analysis. The ...
Estimates of genetic Parameters for growth of Kenya Boran cattle using Random Regression models
(2006)
Data consisting of 18 884 weight records collected from 1 273 Boran cattle from birth to 24months of age were
used to estimate genetic parameters for growth of Boran cattle using random regression (RR) models under ...
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. ...
