Effects of curcumin supplementation on quality of porcine spermatozoa irradiated with ultraviolet‐C at 228nm during liquid preservation

It is important to prevent microbial contamination during liquid preservation of semen in pigs. We examined the effects of curcumin supplementation on the quality of porcine spermatozoa irradiated with ultraviolet‐C (UV‐C) at 228 nm. UV‐C is used to disinfect gases and solid surfaces. In the first e...

Description
Summary:It is important to prevent microbial contamination during liquid preservation of semen in pigs. We examined the effects of curcumin supplementation on the quality of porcine spermatozoa irradiated with ultraviolet‐C (UV‐C) at 228 nm. UV‐C is used to disinfect gases and solid surfaces. In the first experiment, porcine semen was preserved with 0, 10, 25, 50 or 100 μM curcumin under UV‐C irradiation at 228 nm for 7 days at 15°C. The irradiation did not affect the motility and viability of preserved spermatozoa but decreased the percentage of plasma membrane integrity of spermatozoa. Curcumin supplementation at 25 μM significantly improved the plasma membrane and acrosome integrity of irradiated spermatozoa compared with spermatozoa preserved without curcumin (p
