Together with Susan Slaviro, we bought Tietse 428 from the breeder M. Doller (also the breeder of Leffert 306). Tietse 428 is the first stallion to be approved at the Friesian Studbook on his achievements in the higher level dressage. He also was the first approved Friesian stallion to perform at Grand Prix level dressage. In six years of breeding at The Voorsprong Stables, Tietse 428 has produced more than a thousand offsprings. This number shows the amount of trust many Friesian breeders have in Tietse 428. Unfortunately, the studbook didn’t. Without further explanation, the studbook unapproved Tietse 428. There are more than sixty Friesian stallions, which are approved on offspring, with a lower breeding value than Tietse 428. Thats a fact. Tietse 428 is and always will be the king of The Voorsprong Stables, and that’s also a fact!
