Background and Objective: PAX7, a member of the paired box family of transcription factors, plays a critical role in forming skeletal muscles and regulating the satellite cell in vertebrates, including chickens. In this study, the genetic association of the PAX7’s 31-bp indel with carcass traits of Noi chicken, a recognized Vietnamese native breed was analyzed. Materials and Methods: A total of 355 Noi broilers (164 males and 191 females) were slaughtered at 91 days old to evaluate carcass characteristics. Blood samples were collected for DNA extraction. Genotyping the PAX7’s 31-bp indel was based on the length of different fragments such as 588 and 557 bp corresponding to E and F alleles. Results: Its was owed that the genotypes of PAX7 were significantly associated with wing weight and drumstick weight of the Noi chicken (p<0.05), whereas chickens with the FF genotypes always displayed the highest values. Moreover, the interaction between these genotypes of the PAX7 and bird sex was statistically significantly associated with most of the observed traits (p<0.05), except the weight of abdominal fat (p>0.05). Conclusion: These results suggested that the 31-bp indel PAX7 may be a potential molecular marker for breeding Noi chicken.
