Thirty-two Hubbard and 40 Egyptian Fayoumi (dual-purpose) chickens were slaughtered in series at 2-wk intervals between 2-8 wk and 2-10 wk of age, respectively. Genetic differences in the allometric fat growth equation constants were studied. Relative to total body fat (TBF), the breeds did not differ significantly in relative growth of non-carcass fat. The Fayoumi tended to lay down carcass fa...

Defensins constitute an evolutionary conserved family of cationic antimicrobial peptides that play a key role in host innate immune responses to infection. Defensin genes generally reside in complex genomic regions that are prone to structural variation, and defensin genes exhibit extensive copy number variation in humans and in other species. Copy number variation of defensin genes was examine...

This study aimed to the role of PPARs on fat deposition in native crossbred chicken. We studied growth, abdominal, subcutaneous, and intramuscular fat, mRNA expression PPARA PPARG adipose muscle tissues four chicken breeds (CH breed (100% Thai chicken), KM1 (50% CH background), KM2 (25% broiler (BR)). The result shows that BR chickens had higher abdominal than other (p < 0.05) an percentage ...

Growth traits are under the control of multiple genes. Understanding the genetic information of related genes is helpful for the selection and breeding course through marker assisted selection. The aim of the current study was to investigate the association of A287G SNP in BMPR-1B gene with growth traits in chicken. A single nucleotide polymorphism was identified in 240 individuals using the PC...

BACKGROUND Korean native chicken (KNC) is a well-known breed due to its superior meat taste. This breed, however, owing to a low growth rate, has a high market price. In order to overcome this disadvantage, the National Institute of Animal Science (NIAS) in Korea developed a commercial KNC breed, named Woorimatdag version 2 (WM2), an upgraded version of the Woorimatdag (WM1) breed and the WM2 w...

Chicken, Gallus gallus, is a valuable species both as a food source and as a model organism for scientific research. Here, we sequenced the genome of Gyeongbuk Araucana, a rare chicken breed with unique phenotypic characteristics including flight ability, large body size, and laying blue-shelled eggs, to identify its genomic features. We generated genomes of Gyeongbuk Araucana, Leghorn, and Kor...

Background: Bendiocarbamate is a carbamate insecticide, which belongs among the cholinesterase inhibitors. Cholinesterase inhibitors is a group of chemical compounds, which inhibits acetylcholine hydrolysis by acetylcholinesterase, thereby acetylcholine accumulates in the reactive locations of a living organism. Objective: The aim of the study was to investigate toxicity dose of bendiocarbamate...

Background and Aims: Finding prevalence of chicken anemia virus (CAV) infection in native chickens is necessary to avoid transmission of infection to commercial flocks. In this paper we attempt to describe molecular detection of chicken anemia virus in native Larry-breed chickens in Chaharmahal-va-Bakhtiyari province in Iran for the first time. Materials and Methods: Blood samples were collect...

This study aimed to assess genetic diversity within and between nine Vietnamese local chicken breeds and two Chinese breeds included for comparison. Genotyping 29 microsatellites revealed high diversity of both Vietnamese and Chinese breeds. Cluster analysis using the STRUCTURE software suggested six clusters as the most likely grouping of the 11 breeds studied. These groups encompassed four ho...
