The IAARD has develop KUB-1, Sensi-1 Agrinak chickens and their cross breeding as a source of alternative protein. This research aimed to gain more data information related by-product potencies farming this chicken. sample used were 210 chickenswhich was treated carefully. taken at 6-12 weeks slaughtered-age. observed variables the weight blood, feather internal organs respectively. 3x7 complet...

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...

Quantitative trait locus (QTL) is a particular region of the genome containing one or more genes associated with economically important quantitative traits. This study was conducted to identify QTL regions for body weight and growth traits in purebred Korean native chicken (KNC). F1 samples (n = 595) were genotyped using 127 microsatellite markers and 8 single nucleotide polymorphisms that cove...

The development of genetic markers for animal breeding is an effective strategy to reduce the time and cost required to improve economically important traits. To implement genomic selection in the multibreed chicken population of Korea, an understanding of the linkage disequilibrium (LD) status of the target population is essential. In this study, we performed population genetic analyses to inv...

The AMP-deaminases from chicken and rabbit muscle have been investigated by techniques which include sedimentation equilibrium, sodium dodecyl sulfate gel electrophoresis, amino acid analysis, NH2- and COOH-terminal analyses, and tryptic peptide mapping. The molecular weights of the native chicken (276,000) and rabbit (271,000) enzymes obtained by sedimentation equilibrium studies are in good a...

The presence of native microflora is associated with increased variation of Salmonella growth among batches and portions of chicken meat and as a function of temperature. However, variation of Salmonella growth can be modeled using a 95% prediction interval (PI). Because there are no reports of predictive models for growth of Salmonella on ready-to-eat poultry meat products with native microflo...

background: major histocompatibility complex (mhc) plays a central role in regulation and control of the immune responses to infectious diseases. due to its polymorphism, individual differences in response to vaccines have been observed in different chicken populations. studying the association of chicken mhc with immune response to vaccines will help the control of infectious disease and vacci...

BACKGROUND In previous studies, the Mx Gene has been demonstrated to confer positive anti viral responses in chicken. The amino acid variation of Asn (allele A) at position 631 was specific to positive antiviral Mx/resistant, while, that of Ser (allele G) was specific to negative Mx/susceptible. This research was aimed at selecting one of the native chicken breeds which was found out to be resi...
