Abstract: In this study, 8 pair primers were designed based on erythropoietin receptor (EPOR) RNA (AF274305) and DNA (EU407778) sequences in porcine which were submitted on GenBank. Genetic variation was analyzed by sequencing using a DNA pool from 10 Beijing Black pigs and 10 Large white pigs. The results showed that the porcine EPOR gene contains one 5′untranslated region (UTR), eight exons, seven introns, and one 3′UTR, covering at least 5.2 kb of genomic DNA. 9 new single nucleotide polymorphisms (SNPs) were identified: g.705G＞T in intron 1, g.1450C＞T in intron 2, g.2373C＞T in intron 4, and g.2882C＞T, g.3035A＞G, g.3132A＞T, g.3295C＞T, g.3942C＞>T and g.4106G>A in intron 6.
