Sire: Stallions must be at location at date of conception (gestation length is ± 330 days); The oldest stallion is assumed to be sire.

Dam: Mares which have not reproduced in the year of birth of individuals with unknown dams and are older than 2 years. The oldest mare in the group of horses which matches this criterium is assumed to be the dam. Mares that have been selected as dams are excluded from the breeding pool for that year.
