Abstract: 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.

Key words: canine semen, freezing, thawing, cryoprotectant
