Evaluation of Morphometric Differences among Indigenous Chicken Populations in Bale Zone, Oromia Regional State, Ethiopia
The study was conducted in five selected districts in Bale zone South East, Ethiopia to evaluate the morphometric difference among indigenous chicken populations. Simple random sampling method was used to select 400 households who owned indigenous chicken population. From these households, a total of 840 adult (more than 6 months of age) indigenous chickens (225 males and 615 females) were used...
متن کاملEvaluation of a multi-line broiler chicken population using a single-step genomic evaluation procedure.
Effects on prediction of analysing a multi-line chicken population as one line were evaluated. Body weight records were provided by Cobb-Vantress for two lines of broiler chickens. Phenotypic records for 183 695 and 164 149 broilers and genotypic records for 3195 and 3001 broilers were available for each line. Lines were combined to create a multi-line population and analysed using a single-ste...
متن کاملMultilocus sequence typing analysis of Clostridium perfringens isolates from necrotic enteritis outbreaks in broiler chicken populations.
Clostridium perfringens is an important pathogen of animals and humans and is the causative agent of necrotic enteritis (NE) in poultry. This study focuses on the typing of intestinal C. perfringens isolates (n = 61) from outbreaks of NE collected from several areas of Southern Ontario, using a recently developed multilocus sequence typing (MLST) technique. For comparison, C. perfringens isolat...
متن کاملApplication of single-nucleotide polymorphism (SNP) as a molecular marker in the study of genetic diversity of aquatic populations
Genetic diversity is one of the important and essential characteristics of any population for its survival. The study of genetic variation in different populations of aquatic organisms is of particular importance in order to protect, stabilize and manage their stocks. Based on studies conducted in recent years, molecular markers have proven that they can be used as indicators of the genetic div...
متن کاملGenetic diversity and conservation of South African indigenous chicken populations.
In this study, we compare the level and distribution of genetic variation between South African conserved and village chicken populations using microsatellite markers. In addition, diversity in South African chickens was compared to that of a reference data set consisting of other African and purebred commercial lines. Three chicken populations Venda, Ovambo and Eastern Cape and four conserved ...
