![]() ![]() Statistical analyses evaluated the consumption patterns of native chickens, preference marketing for native chicken breeds which will be newly developed, and price sensitivity measurement (PSM). A survey was conducted from Jan 6 to 17, 2014, and data were collected from consumers (n=500) living in Korea. This study analyzed consumers' preferences and price sensitivity to native chickens. Lee, Min-A Jung, Yoojin Jo, Cheorun Park, Ji-Young Nam, Ki-Chang The phylogenetic tree and median network profiles showed that Chinese native chickens and its neighbouring countries had at least two maternal origins, one from Yunnan, China and another from Southeast Asia or its surrounding area.Īnalysis of Consumers' Preferences and Price Sensitivity to Native Chickens. It was concluded that these 4 Chinese chicken breeds had high genetic diversity. ![]() Four haplogroups (A, B, C and E) emerged in the median-joining network in these breeds. Both the Xichuan black-bone chicken and Yunyang black-bone chicken were grouped into one cluster. ![]() Three clusters were formed in 4 Chinese native chickens and 12 reference breeds. The haplotype diversity and nucleotide diversity of these 4 native breeds were 0.916 ± 0.014 and 0.012 ± 0.002, respectively. The results showed that a total of 33 mutation sites and 28 haplotypes were detected in the 4 chicken breeds. The mtDNA D-loop sequence polymorphism and maternal origin of 4 chicken breeds were analysed in this study. In addition, 30 mtDNA D-loop sequences of Silkie fowls were downloaded from NCBI. To explore the genetic diversity of Chinese indigenous chicken breeds, a 585 bp fragment of the mitochondrial DNA (mtDNA) region was sequenced in 102 birds from the Xichuan black-bone chicken, Yunyang black-bone chicken and Lushi chicken.
