Investigation of the efficiency of ethylene glycol and sucrose application in the capacity of cryoprotectors for cryopreservation of cattle embryos and their thawing in the conditions of application of saline solutions (as their dissolution medium) and nutritive media with a various structure was realized in the conditions of the Republic of Belarus. Research results showed that application of ethylene glycol in concentration 1,5 M and sucrose in concentration 1,0M proved to be the most effective. Regardless of the applied media the average safety of embryos was 93,8-96%, and acceptability - 59,3-62,5%. Peculiar feature of ethylene glycol use as cryoprotector for preservation of cattle embryos was that it could be quickly absorbed by a cell and quickly deduced from it. It made it possible to realize embryo transfer immediately after thawing. Application of ethylene glycol and sucrose as cryoprotectors could considerably simplify the procedure of transplantation of the frozen-thawed embryos, practically reducing it to a procedure of artificial insemination
