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 ...
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 ...

Comparison of economic impact of alternative constraint control measures in indigenous chicken production in Nyanza Province, Kenya
(CIPAV Foundation, 2013)
This study compared the costs and benefits of six alternative control measures on the indigenous chicken productivity constraints with an aim of identifying the most desirable mitigation measure; for improved productivity ...
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 ...
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 ...
