Grape Seed Procyanidin Extract (GSPE) Improves Goat Sperm Quality When Preserved at 4 °C

摘要

Artificial insemination (AI) is widely used in goats, stimulating the development of semen preservation techniques. Oxidative stress is considered to be the main cause of sperm quality decline over time. In this study, we explored the effect of grape seed procyanidin extract (GSPE) during the liquid preservation of goat semen. The results showed that adding GSPE into the basic diluent enhanced sperm quality by eliminating oxidative stress. The most suitable concentration for the preservation of goat semen at 4 °C was 30 mg/L. This work suggests that promotes the viability of goat semen stored at low temperatures and provides a theoretical foundation for the development of more efficient diluents.
