In pigs, correlations between mitochondrial (mt) DNA polymorphisms and economic traits have been widely reported across and within swine breeds. In fecundity studies, the number of oocytes within ovaries was highly correlated with litter size. However, the effect of mitochondrial polymorphisms on porcine oocyte number remained unclear. In this study, 181 porcine ovaries were collected to analyse the relationship between oocyte number and mtDNA polymorphisms. There were considerable differences in oocyte numbers among different ovaries from commercial pig breeds, ranging from 2.7x10(5) to 1.3x10(6). Mitochondrial D-loop sequencing discovered 53 polymorphic sites. Association analysis revealed that 13 variations were associated with the number of oocytes (P
