| Objective of this study was to detect the SNPs of GHSR, IGFI, cGH and IGFBP2 genes and their association with growth traits (body weight at 0, 4, 8, 12 and 16 weeks of age, ADG during 0-4, 0-8, 0-12 and 0-16 weeks of growth) and carcass trait (breast width) of Thai native chickens (Chee and Pradu Hang Dam). Blood samples were randomly collected from 60 chickens/breed. The genotypes were detected using PCR-RFLP methods with specific primers for each gene. A mixed model was used to analyze the associations of candidate genes with growth traits. In Chee, the GHSR gene was not significantly associated with growth traits, while, the IGFI gene was significantly associated with body weight at 12 and 16 weeks of age and ADG during 0-12 and 0-16 weeks of age.
