Abstract This paper summarized the recent achievements of DNA barcode in animal identification studies. The DNA barcoding literature of study animals and their selected DNA barcode were analyzed. The most studies involved invertebrates and reptiles. While mammals were reported fewer, among these research mainly focused on bats and rats, but no study of Chinese local pigs. The paper also described the phylogenetic research progress in Chineselocal Pigs. The current classification system of Chinese local pigs on the molecular evidence is deficient, and the number of research involved is limited. Molecular phylogenetic studies of Chinese local pig have just started. At the same time, the paper especially emphasized the application prospects and analyzed the feasibility of DNA barcodes in genetic resources conservation for local pig studies.
