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 ... -
Genetic and non-genetic factors influencing KLH binding natural antibodies and specific antibody response to Newcastle disease in Kenyan chicken populations
(Wiley Online Library, 2023)This study aimed at investigating the influence of genetic and non-genetic factors on immune traits to inform on possibilities of genetic improvement of disease resistance traits in local chicken of Kenya. Immune traits ... -
Genetic and non-genetic sources of variation in natural antibodies titre values among indigenous chicken
(American Journal of Research Communication, 2017)Innate immunity plays significant role in combating disease. Improvement of any trait including resistance to disease and infection requires identification of genetic and nongenetic sources of variation. This study aimed ... -
Genetic and nutrition development of indigenous chicken in Africa
(2015)This review gives insights into genetic and feeding regime development for indigenous chicken genetic resources. We highlight and combine confirming evidence of genetic diversity and variability using morphological and ... -
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 ... -
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 ... -
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 ... -
Genetic evaluation of growth of Kenya Boran cattle using random regression models
(Springer Netherlands, 2007-10-01)Data consisting of 18 884 weight records collected from 1273 Boran cattle from birth to 24 months of age were used to estimate covariance functions and genetic parameters for growth of Boran cattle using random regression ... -
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 ... -
Genetic parameters for growth and reproductive traits in the Kenya Boran cattle.
(Instituto Prociência, 2006)see more details (WW), 12-month weight, 18-month weight and 24-month weight were 0.36, 0.40, 0.38, 0.21 and 0.17, respectively while estimates for age at first calving age at first calving Subject Category: Properties -
Genetic parameters for weaning weight of Kenyan Boran cattle accounting for direct-maternal genetic covariances
(South African Society for Animal Science, 2006)Genetic parameters were estimated for weaning weight (WW) in Kenya Boran cattle using animal models that assumed non-zero direct-maternal genetic covariance. In addition to the direct and maternal genetic effects, maternal ... -
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 ... -
