【 摘 要 】
References(23)Canine embryos (8-cell to blastocyst stages) frozen-thawed using the slow-freezing methodwith glycerol (four recipients) or dimethyl sulfoxide (three recipients) as acryoprotectant and vitrified-warmed using the Cryotop method (five recipients) weresurgically transferred into the unilateral uterine horn of recipient bitches. As a result,the morphology of embryos frozen-thawed using the slow-freezing method was judged to benormal, but no conception occurred in any of the recipient bitches. Two of the fivebitches that received transferred embryos (morula to early blastocyst stages)vitrified-warmed using the Cryotop method became pregnant and produced normal pups (1/9embryos, 11.1% and 1/6 embryos, 17.0%). It was concluded that the Cryotop method was moreappropriate for canine embryo cryopreservation than the slow-freezing method, which isused for the cryopreservation of embryos of other mammalian species.
