this study was conducted to investigate direct and maternal effects on some economic traits in north iranian native fowls. traits considered were body weight at 1 day of age (bw1), body weight at 8 weeks of age (bw8), body weight at 12 weeks of age (bw12), egg number (en) during the first 12 weeks of laying period, egg weight at 1st day of laying (ew1), mean egg weight at 28th, 30th and 32nd we...
Biochemical polymorphism study is a method of determination of genetic variation. This variability could be a basis for selection and subsequent genetic improvement in farm animals. The polymorphism in the intron 1 of chicken growth hormone (cGH) gene was investigated in the Iranian native fowls by using polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) method. The...

In the present study for evaluation of genetic variability within and between Iranian native fowls, thirty nine blood samples were randomly collected from native fowls breeding stations of west Azarbayjan, Khorasan, Fars, Mazandaran, Yazd and Esfahan provinces. Inorder to compare the obtained results with other Asian, African and European breeds the D-loop sequences of mtDNA taken from GenBan...
This research was carried out in order to detect the polymorphisms in four sites of PEPCK-C gene by PCR-RFLP method in a commercial layer and broiler strains and breeder hens of Mazandaran native fowls breeding station. Blood samples were collected randomly from 150 birds from a three populations and DNA was extracted using modified salting out method. Using polymerase chain reaction (PCR)...
background: the aim of this study was to determine the prevalence, intensity, and species of internal and external parasites of native fowls from golestan province, north of iran. methods: during 2007, different organs of 26 and 24 adult female native fowls collected from humid parts (gorgan, kord kooy, ramian and bandar gaz) and dry regions (gonbad kavoos, and bandar torkaman) of golest...
The efficiency of insertion and/or deletion (indels) polymorphisms as genetic markers was evaluated by genotyping 102 indels loci in native chicken populations from Myanmar and Indonesia as well as Red jungle fowls and Green jungle fowls from Java Island. Out of the 102 indel markers, 97 were polymorphic. The average observed and expected heterozygosities were 0.206 to 0.268 and 0.229 to 0.284 ...
while performance-based language assessment has led to an increased authenticity and content validity in the practice of writing assessment, the reliability of ratings has become a major issue. research findings have shown different reactions by native english speaker (nes) and non-native english speaker (nns) teachers to students’ writings. the focus of this study is on investigating whether i...
Here, we studied the genetic diversity of native fowls in Laos by analyzing a mitochondrial DNA (mtDNA) sequence polymorphism. A 546-bp fragment of the mtDNA D-loop region was sequenced in 129 chickens from the areas of Vientiane, Luang Prabang and Pakse. In total, 29 haplotypes were identified and formed five clades. Haplotype diversity and nucleotide diversity of the native fowls in Laos were...
The aims of this study were to compare the promoter sequence of the mannose-binding lectin (cMBL) gene in Iranian native and commercial chicken strains; as well as to compare the cMBL gene expression in crossbred and inbred chickens. In total 79 native (Western Azerbaijan native fowls, WANF) and 49 commercial (Arian Commercial Strain, ACS) birds were reared as parents under same management prac...
