IMPROVEMENTS TO METHODS FOR PREPARING EQUINE EMBRYOS FOR CRYOPRESERVATION

摘要

The invention concerns a method for preparing an equine embryo consisting in, previously to subjecting said embryo to the action of cryoprotectant(s), in subjecting it to a suitable treatment to eliminate the embryonary capsule or to increase said capsule permeability, in order to reinforce the subsequent action of said cryoprotectant(s). Preferably, the embryonary capsule is destroyed or simply made more permeable by a treatment based on collagenase or trypsin.
