A method for the cryopreservation of zona pellucida-intact, early-stage swine embryos, morulae and blastocysts includes centrifuging the embryos prior to cryopreservation in order to remove intracytoplasmic lipids. The lipids are localized external to the embryo proper inside the zona pellucida, thus neutralizing harmful effects which prevent subsequent embryological development. The embryos may be cryopreserved by vitrification or conventional freezing. After recovery and rehydration, zona pellucidae are removed, and intact, viable embryos are transferred to recipient females.

L'invention concerne un procédé de cryopréservation d'embryons porcins à un stade précoce et à zone pellucide intacte, de morulae et de blastocystes. Ce procédé consiste à centrifuger les embryons avant la cryopréservation afin d'éliminer les lipides intracytoplasmiques. Ces lipides sont localisés à l'extérieur de l'embryon proprement dit, à l'intérieur de la zone pellucide, ce qui permet de neutraliser les effets nuisibles qui empêchent le développement embryonnaire ultérieur. Ces embryons peuvent être cryopréservés par vitrification ou par congélation classique. Après récupération et réhydratation, les zones pellucides sont éliminées, et les embryons intacts viables sont transférées dans des femelles receveuses.
