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.

Frequently asked questions

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.
