Pieter is a 5* Grand Prix winner, a World Cup Finalist and 2019 European Champion on the Belgian Team. All of his Grand Prix horses are self-produced and some are even self-bred. Being immersed in showjumping of the highest level, Pieter plays a crucial role in determining stallions for the MoM’s and is the liaison between MoM owners who entrust us with their mares.

Her experience in breeding spans more than a decade and Martine had bred horses like Kriskras DV of Bart Bles en Carpe Diem DV Z of Pieter Devos. Her homebred horses are rarely sold before the age of 5 giving Martine all the insight of the development of a horse, from foal to Grand Prix winner.

Frederik is the commentator of the Longines Global Champions Tour and Global Champions League. He is also the auctioneer of leading auctions such as Z Quality Auction, KWPN Select Sales and Verdener Auction of the Hannoveraner Studbook. During the last 20 years behind the microphone Frederik has developed a condition called Equencylopidia, meaning that his head is full of equine facts and figures.

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.

Can I have a frozen embryo insured?

Yes, this is possible. At the end of the order process, you can opt to buy an embryo with insurance by Catherine De Buyl Horse Insurance. This insurance covers death of the frozen embryo during storage, implantation, pregnancy, birth and the foal’s death within 120 days of its birth. The insured amount in this case will be equal to the embryo’s purchase price, less the cost of the insurance policy. The terms and conditions of this policy are available upon request.
