A pedigree is a formal record of an animal’s ancestry, typically presented as a genealogical chart listing the names of sires and dams across multiple generations. In horses, pedigrees are maintained by breed registries and are central to the studbook system that defines and preserves breed characteristics. A standard three-generation pedigree identifies the sire, dam, paternal grandsire, paternal granddam, maternal grandsire, and maternal granddam, providing the minimum information for evaluating an individual’s genetic background. Extended pedigrees of five or more generations are used in Thoroughbred racing and other performance disciplines to assess inbreeding coefficients and the presence of influential foundational ancestors. The dam’s contribution to the genealogical record‘s contribution and the sire’s producing record in pedigree analysis‘s producing record are both reflected in a well-constructed pedigree analysis. Breeds such as the Thoroughbred and Arabian trace every registered individual to a small number of founding bloodlines, making pedigree documentation essential for registration eligibility. The pedigree of a purebred horse is the basis for its stud book entry and registration certificate. For crossbred or grade horses without documented parentage, no recognized pedigree exists, and such animals may instead be described by their observable characteristics and body condition.
