The objective of this study was to develop of semen transport system for cryopreservation and fertility in bull sperm. The ejaculated semen were diluted with Triladyl containing 20% egg-yolk for transportation. Diluted semen was transported by three methods that there were wrapping tissue (Tissue), sinking under 30℃ water (Water) and sinking between warm water and air (Air) methods. Semen was transported within 2 hours in 0.3℃. For this study, the freezing of diluted semen were added with Triladyl containing 20% egg-yolk. And frozen-thawed sperm were estimated with SYBR14/PI double stain for viability, FITC-PNA/PI double stain for acrosome reaction analysis and Rhodamine123 double stain for mitochondrial intact assessment. In results, live sperm (SYBR+/PI-) in Air treatment group (43.3±4.7%) was significantly (p<0.05) higher than other treatment groups (Tissue: 16.3±2.7% and Water: 27.5± 3.1%), dying sperm (SYBR+/PI+) in Air treatment group (55.6±4.7%) was significantly lower than other treatment groups (Tissue: 77.6±3.2% and Water: 67.6±3.3%) (p<0.05). Acrosome reaction in Air treatment group (0.2±0.1%) within live sperm (PI negative region) was significantly (p<0.05) lower than other treatment groups (Tissue: 0.7±0.2% and Water: 0.5±0.1%), the acrosome reaction in Air treatment group (28.6±2.8%) within all sperm also was significantly lower than other treatment groups (Tissue: 44.2±1.8% and Water: 36.2±2.0%) (p<0.05). And mitochondrial intact in Air treatment group within live (97.1±0.4%) and all (61.9±3.3%) sperm were significantly higher than other treatment groups (Tissue: 85.2±3.3%, Water: 87.8±2.9% within live sperm and Tissue: 49.28±3.7%, Water: 42.0±3.1% within all sperm) (p<0.05). Therefore, we suggest that transportation by sinking method between warm water and air was beneficial to improvement of fertility in frozen-thawed in bull semen.참고 자료
