The study was aimed at evaluation of the applicability of selected microsatellite markers in examining genetic diversity in five Polish local chicken varieties (two groups of native crested chickens, crestless native chickens from Subcarpathian region and two groups of native miniature chickens) and reveal their genetic relationships to five purebreds (Leghorn, Rhode Island Red, Sussex, Greenle...

The Jiangxi Province of China has numerous native domestic chicken breeds, including some black skin breeds. The genetic diversity of Jiangxi native chickens is largely unknown, and specifically, the genetic contribution of the grey junglefowl to black skin chickens is not well understood. To address these questions, the complete D-loop region of the mitochondrial DNA (mtDNA) and beta-carotene ...

To assess genetic diversity and maternal origin of Turkish and Iranian native chicken breeds, we analyzed the mtDNA D-loop sequences of 222 chickens from 2 Turkish (Denizli and Gerze) and 7 Iranian (White Marandi, Black Marandi, Naked Neck, Common Breed, Lari, West Azarbaijan, and New Hampshire) native chicken breeds, together with the available reference sequences of G. gallus gallus in GenBan...

The genetic diversity of Bhutanese chickens needs to be understood in order to develop a suitable conservation strategy for these birds in Bhutan. In this, work, we used microsatellite markers to examine the genetic diversity of Bhutanese chickens. Four Bhutanese chicken varieties (Black plumage, Frizzle, Naked neck and Red Junglefowl-like, corresponding to Yuebjha Narp, Phulom, Khuilay and Sei...

Recombinant outer membrane protein H (rOmpH) of Pasteurella multocida strain X-73 can be purified using affinity chromatography but this adversely affects its immunogenicity. The current study presents the results from an intervention study comparing the immunogenicity of rOmpH purified using electroelution with rOmpH purified using affinity chromatography and native OmpH purified using electro...

The objective of this investigation was to study the histological and histochemical structure of the Harderian gland in native chickens. Samples were obtained from 10 male and 10 female adult healthy native chickens. Tissue sections were stained with haematoxylin eosin, Verhoeff ’s, Masson’s trichrome, alcian blue (pH 2.5), periodic acid-Schiff and Gomori’s method for reticulum. The multilobula...

Newcastle Disease (ND) is highly contagious infection of poultry that causes nervous signs and mortality in poultry. This study has been one during two years from 2010-2011 in Shiraz, Iran. The poultry industry in Fars province faced an almost heavy loss that was characterized by mild and in some flocks high mortality and respiratory distress. The aim of this study was designed to clarify the r...
