Single Nucleotide Polymorphisms in Candidate Genes Associated with Egg Production Traits in Native Noi Chicken of Vietnam

Abstract

The aim of this study was to identify single nucleotide polymorphisms (SNPs) in candidate genes known to associate with egg production trait in chicken. In total, 218 hens of native Noi chicken were used for genotyping 14 SNPs of 9 genes namely PRL, GH, VIP, VIPR1, BMPR-IB, MTNR1C, NPY, DRD2 and IGF-I. It was shown that, in Noi chicken population the substitutions of alleles at different loci including C2402T, C2161G, C2983T, G51389822T, A287G, G294A, C31394761T, T5841629C, C1715301T, C1704887T, C338T, D2648 to 2650I and C364T (5’-UTR) were detected with high frequencies of alleles T and G (PRL), A (GH), T and I (VIP), C (VIPR1), G (BMPR-IB and MTNR1C), D and C (NPY), C (DRD2) and B (IGF-I). It is expected that selection based on these polymorphic loci is more effective in increasing reproductive performance of Noi chickens.
