The progeny from thoroughbred and other sport breeds founders were investigated. Genealogical structure development was traced by pedigree analyses of 1123 horses, born after 2000 and registered from Association Eastbulgarian Horse. Since the created in the last century lines in the state studs until today continued development of three of them - the Vustershir, Zenger and Tihani.
