Quantitative breeding theories usually focus on statistical analysis of the sire and broodmare sires in particular. The best-known classification system for mares was developed in the late 1800s by an Australian named Bruce Lowe, who analyzed the statistics of major race winners and ranked the distaff or mare lines by their degree of success ...
Studbook selection is a process used in certain breeds of horses to select breeding stock. It allows a breed registry to direct the evolution of the breed towards the ideal by eliminating unhealthy or undesirable animals from the population.
In the horse breeding industry, the term "half-brother" or "half-sister" only describes horses which have the same dam, but different sires. [6] Horses with the same sire but different dams are simply said to be "by the same sire", and no sibling relationship is implied. [7] "Full" (or "own") siblings have both the same dam and the same sire.
Hack, a basic riding horse, particularly in the UK, also includes Show hack horses used in competition. Heavy warmblood, heavy carriage and riding horses, predecessors to the modern warmbloods, several old-style breeds still in existence today. Hunter, a type of jumping horse, either a show hunter or a field hunter
Interest in determining which sires of race horses transmit raw speed, and which sires transmit stamina (defined as the ability to successfully compete at longer distances) to their progeny dates back to the early 20th century, when a French researcher, Lt. Col. J. J. Vuillier, published a study on the subject (called Dosage), which was subsequently modified by an Italian breeding expert, Dr ...
It originates from warmblood horses bred principally for military use in the nineteenth century. [2] It was officially recognised as a breed in 2005, and a stud-book was started in that year [4]: 154 [3]: 148 [2] or in 2006. [5]: 9 Only horses with at least 87.5%, but less than 100%, Thoroughbred blood are eligible for registration. [2]
The General Stud Book is a breed registry for horses in Great Britain and Ireland. More specifically it is used to document the breeding of Thoroughbreds and related foundation bloodstock such as the Arabian horse. Today it is published every four years by Weatherbys. [1] Volume 49 was published in 2021. [2]
The average is stated as a value of 1.00. The AEI is calculated for each year a horse has offspring racing and can be averaged for all years that horse has had first generation descendants on the track. [2] The AEI can be used for additional comparisons, such as the composite AEI of a sire or damsire based on all of his progeny.
