不同冷源对民猪精液冷冻保存效果的影响

Influences of Different Freezing System on Cryoprotective Effects of Frozen Semen in Min Pig

用干冰和液氮作为冻源对民猪精液冷冻效果进行研究,包括对精子活率及顶体完整率的影响。结果表明,以干冰为冻源进行民猪精液冷冻,解冻后精子活率为43.5%,顶体完整率为52.2%;以液氮为冻源进行民猪精液冷冻,解冻后精子活率为41.8%,顶体完整率为51.5%,二者差异不显著。

The cryoprotective effects of dry ice and liquid nitrogen on frozen-thawed semen in the Min pig were studied,including sperm motility and acrosome integrity.The result showed that the sperm motility is 43.5％ and the sperm acrosome integrity is 52.2％ by dry ice; the sperm motility is 41.8％ and the sperm acrosome integrity is 51.5％ by liquid nitrogen.There have no significant differences between the dry ice and liquid nitrogen.
