CASTLEFIELD Breeding Farm, the partnership formed by Ger O’Neill and Italian business man Matteo Delmiglio, will be standing five sport horse stallions for the 2026 breeding season. The roster is headed by the Zangersheide pair of Asca Z (Askari x Carthago) and Solid Gold Z (Stakkato Gold x Calvin Z), whose presence at O’Neill’s Kilkenny base will mean that Irish breeders have access to fresh semen from two proven 1.60m stallions seven days a week.

The latter should already be familiar to some Irish breeders, as he shares the same sire as Seamus Hughes Kennedy’s star performer ESI Rocky, who finished in the top five individually at last year’s Senior European Championships, as well as jumping double clear on the third-placed Irish Aga Khan team. Solid Gold Z was the seven-year-old World Champion at Lanaken in 2018 in his own right, and he went on to have a successful career at the highest level with Christian Ahlmann.
