Price on application Details about Spring Bull Calves 2026
Full-blood Wagyu, bred in Co. Kildare since 2008
Registered, DNA-verified breeding stock, semen and embryos — selected on Australian figures rather than looks, and exported to buyers across Europe.
The herd
It started with fifty-one embryos
We imported 51 Wagyu embryos from Australia in 2008, at roughly the cost of a new tractor. The conception rate was poor. What saved it was two exceptional animals — a cow called Ohanasaki Breda, who had forty-two calves born in a single year and traces back to Dai 2 Kinntou, and a stock bull called Ohanasaki Brilliant, who was quieter and kinder than a Saint Bernard and whose semen is still in demand at home and abroad.
Everything here is bred from that foundation on 110 acres at Silliot Hill. We sell to farmers starting or strengthening a herd of their own, and we are happy to spend the time on the phone that a decision like that deserves. If you are weighing up whether Wagyu suits your ground, ring us — an honest conversation costs nothing, and if the answer is no we will tell you.

Oliver on breeding, bloodlines, marbling and the practical realities of finishing Wagyu in an Irish system.
The Last Hundred Days: Why Marbling Shows Up When It Does
And what the biology of intramuscular fat means for how you feed, when you sell, and where your money actually goes.
Does Wagyu Actually Work in an Irish Grass System?
The breed is often sold on the romance of Kobe. The real question for an Irish farmer is whether a 34-month finish pays on grass — and under what conditions it does.
Understanding Wagyu Bloodlines — Tajima, Kedaka and the Trade-off
Breeders talk about prefectural lines constantly, and newcomers nod along. Here is what the lines actually mean and why chasing one of them exclusively is a mistake.
