摘要:

为探究不同稀释液对鸡精液冷冻保存效果的影响,选择LR、Lake’s、BPSE、Modified Sasaki、Beltsville和Nabi共6种稀释液对霞烟鸡精液进行冷冻,解冻后分别在37或4 ℃条件下短时间保存,分析不同冷冻稀释液和保存条件对精子活率、活力、功能完整性和抗氧化指标的影响。结果表明,6种稀释液中Lake’s稀释液的冻后活率、活力和顶体完整性最高,分别为48.20%、45.70%和45.26%;LR稀释液虽然获得了48.16%的冻后活率,但其活力显著低于Lake’s稀释液。解冻后4 ℃保存更适合鸡精子的短时间保存,Lake’s和Nabi稀释液在4 ℃条件下保存45 min后活力仍达30 %以上。虽然Nabi稀释液解冻初始时的精子活率和活力低于LR和Lake’s稀释液,但随着保存时间的延长,其冻后精子存活能力表现最佳。随着冻后保存时间的延长,LR、Lake’s和Nabi稀释液冻后精子的线粒体活性、质膜完整性和抗氧化能力均呈现下降趋势,且37 ℃保存时下降更为明显,同时LR稀释液在这些指标上表现出较差的耐受性。综上所述,Lake’s和Nabi冷冻稀释液对鸡精子冷冻保存的效果最佳;解冻后4 ℃保存可延长冻精的体外存活时间;LR稀释液虽获得了较高的冻后活率,但其活力和冻后耐保存性能较差。

Abstract:

In order to explore the effects of different diluents on rooster semen cryopreservation, 6 diluents (LR, lake’s, BPSE, modified Sasaki, Beltsville and Nabi) were respectively used for the cryopreservation of Xiayan roosters semen. The semen was briefly stored at 37 and 4 ℃ after thawing. The viability, motility, functional integrity and antioxidant capacity of sperm treated with different diluents and storage conditions were determined. The results showed that lake's diluent got the highest viability (48.20%), motility (45.70%) and acrosome integrity (45.26%). The viability in LR diluent treatment after thawing was 48.16%, which the motility rate in LR treatment was significantly lower than those in lake’s diluent treatment. 4 ℃ was more suitable for short-term preservation of rooster sperm after thawing, and the viability of rooster sperm in Lake’s and Nabi diluents could still reach over 30% after 45 min storage. Although the viability and motility of sperm in Nabi diluent were lower than those in LR and lake’s diluents at 0 min, it showed the best viability ability with the extension of preservation time. The mitochondrial activity, plasma membrane integrity and antioxidant capacity of frozen sperm in LR, Lake’s and Nabi diluents decreased with storage time, which the decreased range was more obvious when stored at 37 ℃. Furthermore, the semen in LR diluent showed a worse tolerance on these indicators. In conclusion, the lake’s and Nabi diluents were more suitable for rooster semen freezing. The storage at 4 ℃ after thawing could prolong the survival time of frozen sperm in vitro. The sperm in LR diluent showed a high viability after thawing, but lower motility and preservation resistance.
