Our story

The story of Mares of Macha

Discover our mares

In 2018 we set a goal to breed great showjumpers. Essentially that’s the goal every breeder has but we aimed high and wanted to start high. So we tried to figure out what all these topperformers had in common. We ended up with 3 markers that most stars shared: pure performance, passing on the talent to offspring and depth of performance in the family. With that knowledge saved, we went straight for the source. From Stephan Conter we managed to find and buy the holy grail for many breeders. Goya, a young and straight daughter of the unsurpassed Usha van’t Roosakker and full-sister tis several 5* Grand Prix horses. At Jos Lansink’s we found a daughter of Ta Belle van Sombeke, a sister to London. The icing of the cake was Contara, the mother of Chacco-Blue. We had launched our breeding project.

The joy for our first acquisitions must have worked contagious on our good friends, the family Devos. As passionate and successful breeders, they saw the potential of our project and joined it.

This collaboration resulted in the addition of several sports mares from Pieter’s network. The search continued and after the joining of Frederik De Backer, the collection enlarged to 36 mares. Each of the 36 matched the markers, some even scored the maximum on all 3! The project needed a name. A title that would emphasize the pivotal position of our mares. The mothers of future sporthorse, our MoM’s, our Mares of Macha. She, Macha, is a godess of the Irish mythology where she is often represented with a foal, symbolizing the importance of mares. She now protects ours. The genes and the talent of our Mares is now available to every breeder.

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

Breeding starts with the wellbeing 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.
