KWPN
The Trakehner is used as a "refiner" of other breeds, allowing an infusion of Thoroughbred and Arabian blood without the risks often involved in first generation outcrosses. Influential stallions include Abglanz for the Hanoverian, Herbststurm who influenced the Oldenburg, Marco Polo for the Dutch Warmblood, the stallions Ibikus and Donauwind for the Danish Warmblood, and Polarstern for the Swedish Warmblood.
