Kele pig (Sus scrofa), a semi-captive native breed in the Southwest of China, have a range of light to dark brown shades phenotype, just like the coat color of Duroc in some way, and also are well known for their good meat quality. However, Kele pigs decreased dramatically in recent years. The first complete mitochondrial genome of Kele pig was sequenced by next-generation sequencing in order to develop the mitogenome data for genus S. scrofa. The total length of the mitogenome is 16,828 bp, which contains 1 control region, 2 ribosomal RNA genes, 13 protein-coding genes and 22 transfer RNA genes. Phylogenetic analyses based on the complete sequences from several breeds were analyzed by neighbor-joining methods and showed that Kele pigs have closer relationships with domestic pigs in southwest region of China. These results are useful for pig phylogenetic study and evolution study of pig genomes.
