Climate-smart agriculture (CSA) has been promoted in Kenya as a panacea for climate change impacts on agricultural productivity. Consequently, various climate-smart aquaculture technologies, innovations, and management practices (CSA-TIMPs) have been developed, validated, and adopted through the Kenya Climate-Smart Agriculture Project (KCSAP).

The study evaluated response to selection from within-breed selection strategy for conventional (CBS) and genomic (GBS) breeding schemes. These breeding schemes were evaluated in both high-health environments (nucleus) and smallholder farms (commercial). Breeding goal was to develop a dual-purpose IC for both eggs and meat through selective breedin...

The current study aimed at development of breeding objectives and estimation of the economic values for traits of economic importance to various dairy goat breeders associations. This was achieved through the development of a bio-economic model to derive economic values for the selected traits. The input and output parameters used represented the a...

Abstract In Kenya, many farmers have embraced fish farming to curb food shortages, poverty and the creation of employment. However, they face the challenge of the high cost of quality fish feeds. Most depend on feeds like fish and soybean meals as major protein ingredients for fish. Such feeds are very expensive and not readily available thus disco...

Climate change poses a significant threat to livestock production systems, including changes in temperature and rainfall patterns, increased frequency of extreme weather events, and the spread of diseases. The use of genome editing technologies presents a potential solution to mitigate the impacts of climate change on livestock. This paper reviewed...

Diseases remain a major challenge in chicken population leading to reduced performance and economic losses. Whenever possible, chicken population should be reared under production systems with minimum predisposing factors to diseases and other shortcomings during their productive lifetime. Selection for resistance is an attractive option when respo...

Artificial and natural selection in livestock is expected to leave unique footprints on their genomes. Goat breeds in Kenya have evolved for survival, breeding, and production in various harsh ecological areas, and their genomes are likely to have acquired unique alleles for adaptation to such diverse production environments and other traits of eco...

Most parts of Eritrea are classified as arid and semi-arid land (ASALs) which are characterised by dryness, high ambient temperatures and low precipitation. The country has three different environmental landscapes: highland, Western lowland and Eastern lowland agro-ecological zones (AEZs). The geophysical and biophysical characteristics of the AEZs...

A chicken genome has several regions with quantitative trait loci (QTLs). However, replication and confirmation of QTL effects are required particularly in African chicken populations. This study identified single nucleotide polymorphisms (SNPs) and putative genes responsible for body weight (BW) and antibody response (AbR) to Newcastle disease (ND...

Population structure and relationship information among goats is critical for genetic improvement, utilization, and conservation. This study explored population structure and level of introgression among four goat breeds in Kenya: the indigenous Galla (n = 12) and three imported breeds, the Alpine (n = 29), Toggenburg (n = 31), and Saanen (n = 24)....

In Rwanda, the most prevalent livestock farming activity carried out to improve livelihoods in rural areas is poultry farming. The most common bird species raised for egg and meat production is indigenous chicken (IC). Despite its economic significance, the improvement programs in Rwanda have given IC little attention. There is, therefore, little d...

Garcinia kola (Heckel) is a versatile tree indigenous to West and Central Africa. All parts of the tree have value in traditional medicine. Natural populations of the species have declined over the years due to overexploitation. Assessment of genetic diversity and population structure of G. kola is important for its management and conservation. The...

Population structure and relationship information among goats is critical for genetic improvement, utilization and conservation. This study explored population structure and level of gene intermixing among four goat genotypes in Kenya: Alpine (n = 30), Toggenburg (n = 28), Saanen (n = 24) and Galla (n = 12). The population structuring and relatedne...

Rwanda has about 4.5 million of indigenous chicken (IC) that are very low in productivity. To initiate any genetic improvement programme, IC needs to be accurately characterized. The key purpose of this study was to ascertain the genetic diversity of IC in Rwanda using microsatellite markers. Blood samples of IC sampled from 5 agro-ecological zones...

Abstract Cattle production plays important socio-economic roles at household and national levels in Eritrea. The grazed cattle sector dominates the agricultural production occurring mainly in pastoral and agro-pastoral systems. Indigenous cattle breeds are almost exclusively reared in the two production systems. The breeds have notable physical dif...

Genomic selection is a new breeding strategy which is rapidly becoming the method of choice of selection. It is useful in predicting the phenotypes of quantitative traits based on genome-wide markers of genotypes using conventional predictive models such as ridge regression BLUP. However, these conventional predictive models are faced with a statis...

The main aim of the current study was to establish the genetic diversity of the Rwandese indigenous chicken (RIC) using microsatellite markers. This aim was investigated by sampling indigenous chicken genetic materials from 5 agro-ecological zones in Rwanda. The collected blood samples were subjected to DNA extraction, PCR amplification and genotyp...

Survey data obtained from consumers from three regions of Kenya were analysed to identify consumers’ preferences towards IC meat and eggs. Indigenous chicken consumers were further clustered based on their preferences. The analysis was carried out in three stages. The first was crosstab analysis to generate descriptive statistics. Secondly was a pr...

Abstract Indigenous chickens (IC) are a valuable genetic resource due to their adaptability to local climatic and environmental conditions and the need to improve and conserve them has been recognized. Worldwide, tremendous genetic improvement of chicken has been achieved through a combination of pure breeding and crossbreeding programs. In Kenya,...

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. Estimated breeding values were estimated using a sire model. Mean body weight at 12 weeks (BW12) among males and females was 666.7...

The study investigated the genetic make-up of different ecotypes of indigenous chickens (ICs) in Kenya based on major histocompatibility complex (MHC)-linked and non-MHC microsatellite markers. Blood samples were collected from eight regions (48 birds per region) of Kenya: Kakamega (KK), Siaya (BN), West Pokot (WP), Turkana (TK), Bomet (BM), Narok...
