Mares

Freezing embryo

Reasons for freezing embryos include the preservation of genetics, global import or export, the storage of embryos for transplantation at a later date or the possibility of working with a carrier mare.

We use a variety of freezing methods:

  • Embryo smaller than 300 microns: conventional slow freezing method
  • Embryo larger than 300 microns and smaller than 600 microns: vitrification
  • Embryos larger than 600 microns and smaller than 1200 microns: collapsing and vitrification

Good to know

You may choose to flush the donor mare on day 6 or 7 instead of day 8 to prevent the embryo from being too large for freezing.

Gestation results after transplanting frozen embryos are lower than after transplanting fresh embryos: expect gestation rates of 60-70%.

We have the necessary knowledge for transplanting ICSI embryos even if they were not produced by us. When transferring ICSI embryos, a gestation rate of 75% at 14 days gestation can be expected.

Before our veterinarians perform any procedures on your horse, you must have read and signed the health declaration and framework agreement below for approval.
