Abstract: In the present study two mutations (g.14334bpC>G and g.14369bpC>T) at intron 3 in porcine MMP20 gene were identified by Sanger sequencing. These two mutations were completely linked, and the association results showed that they significantly affected the reproduction traits (TNB, TNA, NAd21, BW and LW) in Large White pigs (P<0.05). GG/CC genotype sows had the lowest litter size, followed by GC/CT genotype sows, while CC/TT genotype sows had the highest litter size.

Key words: pig, reproduction traits, MMP20 gene, mutation, association analysis
