Abstract Peroxidation damage induces sublethal injury to boar sperm during the storage process. Taurine has already been demonstrated to protect cells effectively from oxidant‐induced injury. This study was aimed to evaluate the effect of different concentrations of taurine (0.5, 1, 5 and 10 mmol/L ) in Modena diluent on boar sperm quality during liquid storage at 17°C. Ejaculates from sexually mature Duroc pigs were collected, pooled and preserved in the Modena containing different concentrations of taurine. Sperm motility, plasma membrane integrity, acrosome integrity, total antioxidative capacity (T‐ AOC ) activity and malondialdehyde content ( MDA ) were examined every 24 h. Modena diluent containing taurine suppressed the reduction in sperm qualities during the process of liquid preservation compared with those of the control group. After 5 days of liquid preservation, the addition of taurine at 5 mmol/L had the optimal effect on survival time as well as maintenance of motility, plasma membrane integrity, acrosomal integrity, T‐ AOC activity and MDA content. These results may suggest the possibility that the proper addition of taurine to the semen extender improves the swine production system using artificial insemination by the suppressing of sperm damage and subsequent dysfunction during liquid preservation.
