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. ... -
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 ... -

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 ... -
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 ... -
Epidemiological assessment of productivity constraints and appropriate intervention measures on indigenous chicken production in southern Nyanza, Kenya
(University of Nairobi, 2014)The purpose of this study is to determine the factor(s) that limit indigenous chicken productivity; assess and prioritize them and come up with appropriate interventions that are sustainable in this livestock production ... -
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 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 ... -
Preliminary selection results for body weight in indigenous chicken in Kenya
(2015)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. ... -
A procedure for on-farm evaluation of East Coast Fever management in dairy cattle systems: a case of coastal lowlands of Kenya
(2015)A study was designed to develop procedure for valuation of East Coast Fever management through a factor based East Coast Fever management index. It quantified costs of East Coast fever management factors and revenue ... -
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. ... -
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 ... -
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 ... -

Variation and Repeatability of Natural Antibodies Against Keyhole Limpet Hemocyanin of Indigenous Chicken of Kenya
(2016-10-21)The immune system is designed to provide protection to the body by combating a plethora of pathogenic micro-organisms. Identifying animals with a natural ability to make superior immune responses reduces disease occurrences, ... -
Dairy production systems and the adoption of genetic and breeding technologies in Tanzania, Kenya, India and Nicaragua
(Cambridge University Press, 2016-12)Summary Development of the livestock industry and its role in poverty alleviation in developing countries depends on how adaptive the production systems are to changing global environmental and economic trends. This ... -
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 ... -
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 ... -
Effect of sequential teaching methods on retention of knowledge in Biology by secondary schools students in Kenya in Kenya
(2017-05-11)Despite the importance of knowledge in Biology, candidates' performance at the national examination, The Kenya Certificate of Secondary Education (KCSE) is poor. This could be attributed to the teaching methods. The ...
