Additional aspects of pedigree information for genetic sampling on international basis were discussed in relation to the genetic improvement of Holsteins. Dynamic structural changes in the pedigree of the elite cow population are useful for discerning the structural breeding trends and the current mating patterns of the target population. Those information will support the genetic development of young bull sampling programs and the optimum mating systems for the breeding goals of the Holstein in the field.
