犬精液冷冻保存技术的研究进展

国内犬精液冷冻保存技术起步较晚,尚处在研究探索阶段,犬精液冷冻保存技术还不成熟,冷冻精液受胎率、窝产仔数与自然交配相比还有一定的差距,而且品种、地域、采精时间的不同,精液冷冻效果也不一致。从犬精液的冷冻保存方法、冷冻保护剂、解冻方法三个方面,综述了近年来国内外的犬精液冷冻研究成果,为探索更加有效的犬精液冷冻技术,提高犬精液冷冻效果提供参考。

A Review of Recent Advances in Research on Cryopreservation Technology of Canine Semen

The development and application of canine semen cryopreservation technology started relatively late in China, which is still in the research and exploration stage. At present, the mature cryopreservation technology remains limited, and there is still a certain gap in fertilization rate and litter size between the artificial insemination with cryopreserved semen and natural mating. Moreover, the canine variety, regional differences and semen-harvesting time also affect the quality of the cryopreserved semen. This paper renders a review of recent achievements at home and abroad in research on cryopreservation technology of canine semen from the aspects of cryopreservation method, cryoprotectant and thawing method, in hoping to provide references for exploring more effective canine semen cryopreservation technology and improving the cryopreservation effect of canine semen.
