|Abstract||The Royal Dutch Warmblood Studbook (KWPN) is one of the leading studbooks for riding horses in the world. The breeding program of the studbook is aimed at breeding horses that can perform at the highest level in competition of dressage or show-jumping. Breeding for competition traits is complex because the traits are lowly heritable and reliable phenotypes only become available late in life, which compromises the generation interval. As a consequence, genetic trends in competition traits would be low when only recordings from competition would be considered. Recordings on young horses collected during inspections and performance tests are genetically related to the competition traits. Inclusion of young horse information into breeding programs has resulted in more accurate breeding values in particular for young stallions. As a result, genetic trends has increased. Relative recently the studbook has been through a step of specialisation in which horses are more and more bred for only one of the sport disciplines. An overview of the process of specialisation will be given and the genetic consequences will be evaluated.
