The complete mitochondrial circular genome sequence of indigenous Halang pig was first determined with 16,722 base pairs (bp) in length (GenBank accession number: KY800118). The nucleotide composition had the order A>C>T>G feature, namely of these were calculated to be 34.67%, 26.20%, 25.78% and 13.32% respectively. In this genome’s structure, the gene organization was typical of other pigs (Sus scrofa) that contain 13 protein-coding genes, 22 tRNA genes, two rRNA genes and one D-loop region with 1,285 bp in size, all of which are arranged similar in other vertebrates. The derived data of this Vietnamese pig’s mitochondrial genome (mtDNA) and others from Asian domestic pigs and wild boars were used to phylogeny reconstruction by Bayesian inference and Maximum likelihood methods. These results show closest evolution relationship between Halang pig and Lantang pig from South China and some domestic and wild pigs from other nearby geographic regions.
