Future MoM's

A future MoM is mare who isn’t available (to breeders) just yet. Future MoM’s can be currently competing in the sport or they can be too young to give us her embryos. The main ambition of a Future MoM is to prove herself in the sport, later her embryos will become available.

Equine nec-plus-ultra, the home of our MoM’s

Mares are the cornerstone of breeding. We keep our Mares surrounded by the best care, in the vast and sunny fields of Northern Italy on a self-managed property. The mediterranean climate allows year round grazing and the large individual stables with spacious paddocks give our equine athletes the comfort they deserve.

Is your mare a MoM?

Frequently asked questions

What is a frozen embryo?

An embryo is the result of the successful fertilisation of a female ovum or egg and a male sperm cell. A veterinarian collects an ovum from the mare using the OPU (Ovum Pick Up) technique. Then a sperm cell is injected into the ovum under very strict conditions in a laboratory, using specialised microscopic techniques. After approximately 7 days, the success of this fertilisation is determined and if successful, the embryo is frozen to a temperature of -⁠197°C with liquid nitrogen.

What is ICSI?

ICSI is the abbreviation for IntraCytoplasmic Sperm Injection, meaning that a sperm is injected directly into an egg to achieve fertilisation.

Where are MoM's frozen embryos located?

MoM's frozen embryos are stored in two locations. The first is in Italy, where the mares and laboratory are located. The frozen embryos are subsequently transported to the ‘De Morette’ Equine Reproduction Centre in Belgium. This reproduction centre complies with all European regulations and is certified for the storage of frozen embryos. Embryos are shipped to their new owners from this centre.

How can I have my MoM frozen embryo implanted?

If you opt for the ‘no pregnancy no pay’ option, we will take care of the entire procedure for you in partnership with an implantation centre recognized by Mares of Macha.
