Abstract
In this study, the total length of mitochondrial genome of Duroc pig is 16,731 bp, including 34.66% A, 26.27% C, 25.74% T and 13.33% G. Mitochondrial genome contains a major non-coding control region (D-Loop region), 2 ribosomal RNA genes, 13 protein-coding genes (PCGs) and 22 transfer RNA genes. ND2 selects ATT as the initiation codon, and ATA is chose as an initiation codon in ND3 and ND5, the nonstandard start codon is GTG in ND4L and the rest protein common start codon is ATG. The mitochondrial genome of Duroc pig provides an important data in genetic mechanism, which plays an important role in the three-way crossbred pigs.
