Preservation of liquid semen is an important factor for breeding management in swine industry. Oxidative stress of spermatozoa during liquid preservation has a detrimental effect on sperm quality and decreases fertility. Objective of this study was to determine the effect of antioxidant, Quercetin, on capability of porcine liquid semen preservation. Freshly collected porcine semen from boars (n=3), having proven fertility was counted, diluted to 3×107/mL and divided into 5 different semen extenders. Aliquots of diluted semen with different extenders were subjected to measure the pH, motility, viability and sperm DNA structure status on elapse time after preservation for 10 days. For the first 3 days, semen preserved in all 5 different extenders maintained their initial pH and either gradually decreased or increased thereafter, indicating lipid peroxidation has started. Sperm motility (r=0.52, p=0.01) and viability (r=0.55, p=0.03) had positive correlation with semen pH. Sperm motility was maintained well (p<0.05) in especially 2 extenders containing Tris and antioxidant compared to other extenders, suggesting both Tris and antioxidant worked as pH regulator and had beneficial effects on sperm characteristic during preservation. Sperm DNA structure status accessed by sperm chromatin structure assay on elapsed time after preservation, tended to be higher in semen preserved without antioxidant. Taken together, addition of antioxidant to extender prevents the sperm from oxidative stress during storage in mechanism by which antioxidant slows the lipid peroxidation, and thus reduced the reactive oxygen species in preserved porcine semen resulted in maintaining semen pH, sperm motility and viability for 7~ 10 days.
