The Chinese Yakow, Bos primigenius taurus × Bos grunniens, is a large and commercially important hybrid in family Bovidae. We first determined and annotated its complete mitochondrial genome. The mitogenome is 16,322 bp in length, consisting of 13 protein-coding genes, 22 transfer RNA (tRNA) genes, 2 ribosomal RNA (rRNA) genes and a control region. As in other mammals, most mitochondrial genes are encoded on the heavy strand, except for ND6 and eight tRNA genes, which are encoded on the light strand. Its overall base composition is A: 33.7%, T: 27.3%, C: 25.8% and G: 13.2%. The complete mitogenome of Yakow (B. p. taurus × B. grunniens) could provide an important data to further explore the taxonomic status of Yakow (B. p. taurus × B. grunniens) in B. grunniens and enrich the genetic information or evolutionary history of the Bovidae.
