【摘要】：人工授精技术和胚胎移植技术都是在家畜中应用较多的繁殖技术,是一种能够实现猪品种改良的手段。人工授精所用的精液要求精液品质高,活力好。使用精液大多是新鲜精液,其保存时间短,运输过程影响精子活力,易交叉感染的缺点使人们把研究的目标转移到冷冻精液上。冷冻精液可以实现不同地区,甚至不同国家优良种猪精液间的交流,延长精液使用年限,克服使用常温精液不能远距离运输的困难,能够大幅度提高优良种公猪的利用效率,且产生大量的后代,可以充分发挥优良公猪的性能,实现优良品种资源的保存。然而,猪冷冻精液的保存技术经过大量的研究,依然没有在猪生产中得到大规模应用。
[Abstract]:Artificial insemination technology and embryo transfer technology are widely used in livestock reproduction technology is a means to achieve pig variety improvement. Artificial insemination used semen requires high semen quality. Good vitality. The use of semen is mostly fresh semen, its preservation time is short, the transport process affects sperm motility. The disadvantage of easy cross infection causes people to transfer the research target to frozen semen, which can realize the exchange of fine breeding pig semen in different regions and even different countries, and prolong the life span of semen. To overcome the difficulty of using room temperature semen can not be transported over long distance, can greatly improve the utilization efficiency of fine breed boars, and produce a large number of offspring, which can give full play to the performance of good boars. However, the preservation technology of frozen semen has not been widely used in pig production after a lot of research.

【正文快照】： 从18世纪80年代就已经展开了对哺乳动物精液冷冻保存的研究,但进展缓慢。意大利科学家用人和马的精子在-17?℃的寒冷环境下中进行测验,结果发现绝大部分精子都失去活力,只有极少数的精子存活。经过200多年的不断研究,人们逐渐改善了冷冻精液的保存技术。我国的猪冷冻精液保存
