George Z

3 / 7

The Freak!

George Z is a direct son of the sensational Usha van’t Roosakker. This breeding miracle first got praised for her performances in showjumping. However it was only until her first offsprings excelled in the sport that Usha displayed the exceptional genetic potential! Her sons and daughters show the same genetical power, making them the world’s most desired horses.

George Z, being a son of Kannan and Usha, is the full brother to the GP winner Babbe van’t Roosakker of Michel Hecart and he’s a half brother to Cella who, with Ben Maher, won team gold and individual silver at the Europeans in Herning.

However, genetics mean nothing without results. In 2019, as a 7years old, George Z jumped 24 international rounds of which he produced 18 clear rounds and was placed 13 times!

George Z is the prime example of topsport breeding!

The Olympic Champion!

Very rarely has a horse touched so many people as Hickstead, the stallion who died as a Champion and was born as a Legend. 28 international victories, 5 medals at the big championships and Grand Prix wins in Aachen and Spruce Meadows made Hickstead immortal. 

His presence, untamable fighting spirit and unparalleled carefulness made Hickstead an icon of the modern sport. A new generation is coming and is stepping out of their father’s shadow.

Horses like Bianca du Lys with Marie Hecart, Fyenda P of Alex Gill and the highly talented Hickstead White of Gestüt Sprehe, suggest that the story of the Beijing Olympic champion is far from over. Meanwhile, Admara II, bred out of a sister of Hickstead, proves that the genetics behind this showjumping miracle, are based on a very solid foundation.
