Abstract
Xinong Saanen dairy goat (Capra hircus), a breed distributed widely and adapted highly in China, has the characteristics of high milk production and high litter size. Our research revealed that the complete mitochondrial genome of Xinong Saanen dairy goat was 16,639 bp in length. The contents of A, C, G and T in the mitochondrial genome were 33.6%, 26.0%, 13.1% and 27.3%, respectively. It had a typical mitogenome structure, containing 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes and 1 control region. Most of the PCGs have ATG initiation codons, whereas ND2, ND3 and ND5 start with ATA. These results provide essential information for phylogeographic history and population genetic structure, genetic diversity of domestic goats and mitochondrial genome editing based on the goat model.
