Abegaz, S.[A platform for testing, delivering, and continuously improving tropically-adapted chickens for productivity growth in sub-Saharan Africa]A platform for testing, delivering, and continuously improving tropically-adapted chickens for productivity growth in sub-Saharan Africa

The comparative analysis of genome sequences emerging for several avian species with the fully sequenced chicken genome enables the genome-wide investigation of selective processes in functionally important chicken genes. In particular, because of pathogenic challenges it is expected that genes i...

An alignment of 17 complete mitochondrial DNA (mtDNA) sequences of chickens and jungle fowls revealed a perfect mono-nucleotide microsatellite repeat unit consisting of between 8 and 13 Cs within the 16S rRNA gene in nine samples. However, the remaining eight sequences had three kinds of interrup...


Shengguo, Z.Hanotte, Olivier H.Han Jianlin[Identification and characterization of a perfect mono-nucleotide microsatellite within 16S rRNA gene in chicken mtDNA genome]Identification and characterization of a perfect mono-nucleotide microsatellite within 16S rRNA gene in chicken mtDNA genome

We report the mitochondrial DNA (mtDNA) characterization of 77 indigenous chickens (fighting and meat birds) from Madagascar, using DNA sequences of the first hypervariable segment of the D-loop. Comparison with reference samples from the African continent and Asia revealed two mtDNA haplogroups,...

Chicken BLB1 and BLB2 genes are duplicated within MHC-B region that plays a crucial role in disease resistance or susceptibility. To investigate the genetic polymorphism in chicken BLB genes, we analyzed the complete genomic DNA sequences of BLB1 and BLB2 genes from 14 published MHC-B haplotypes ...


Li, X.X.Han, L.X.Han, J.L.[No specific primer can independently amplify the complete Exon 2 of chicken BLB1 or BLB2 genes]No specific primer can independently amplify the complete Exon 2 of chicken BLB1 or BLB2 genes

An endogenous virus, denoted evA, is present at high frequency in all brown egg layer lines. Using inverse polymerase chain reaction (PCR) based on the viral LTR regions, products were obtained containing cellular sequences 5' and 3' to the viral insertion point. PCR of chicken genomic DNA was ca...

Three local types of Sudanese indigenous fowls, large Baladi (LB), Bare-neck (BN) and Betwil (BT) were studied for detection of maturity live weight and egg characteristics. The (BN) average live weight (1547.2±274.5 gm) was heavier than either (LB) (1494.4±349.8 gm) or (BT) (1198.3±257.5 gm), Th...


Mohammed, M.D.Abdalsalam, Y.I.Kheir, A.M.Jin-yu, W.Hussein, M.H.[Comparison of the Egg Characteristics of Different Sudanese indigenous Chicken Types]Comparison of the Egg Characteristics of Different Sudanese indigenous Chicken Types

A study was conducted during the year 2000 to investigate flock size and egg production performance of backyard chicken maintained by woman in rural areas of Peshawar, NWFP, Pakistan. One hundred and thirty female farmers were selected at random from 13 randomly selected nearby villages of Peshaw...

The present study was conducted to assess the performance of indigenous chickens under extensive system in southern Nyanza, Kenya. The study was carried out in two phases in Komolorume and Kawere villages in Rongo and Rachuonyo districts, respectively. The first phase was a cross-sectional study ...
