Single Nucleotide Polymorphisms in Gh, Ghr, Ghsr and Insulin Candidate Genes in Chicken Breeds of Vietnam

Abstract

The aim of this study is to evaluate genetic potential in chicken breeds raised in Vietnam. They include local chicken breeds (Noi and Tau Vang giving good health and meat quality traits but they are not intensively studied yet) and a commercial breed (Cobb 500 giving high growth performance and meat yield in industrial poultry production system in the world, including Vietnam). Therefore, candidate genes GH, GHR, GHSR and insulin related to these traits were investigated for identifying their single nucleotide polymorphisms by using PCR-RFLP method across different populations of chicken. The results provide basic foundation to continuously study the effects of genetic polymorphisms in the candidate genes on performance and meat quality traits of local Vietnamese chickens.
