Next generation sequencing of mitochondrial DNA (mtDNA) facilitates studies into the metabolic characteristics of production animals and their relation to production traits. Sequence analysis of mtDNA from pure-bred swine with highly disparate production characteristics (Mangalica Blonde, Mangalica Swallow-bellied, Meishan, Turopolje, and Yorkshire) was initiated to evaluate the influence of mtDNA polymorphisms on mitochondrial function. Herein, we report the complete mtDNA sequences of five Sus scrofa breeds and evaluate their position within the phylogeny of domestic swine. Phenotypic traits of Yorkshire, Mangalica Blonde, and Swallow-belly swine are presented to demonstrate their metabolic characteristics. Our data support the division of European and Asian breeds noted previously and confirm European ancestry of Mangalica and Turopolje breeds. Furthermore, mtDNA differences between breeds …
