Arabian Horse - Influence On Other Horse Breeds

Influence On Other Horse Breeds

Because of the genetic strength of the desert-bred Arabian horse, Arabian bloodlines have played a part in the development of nearly every modern light horse breed, including the Thoroughbred, Orlov Trotter, Morgan, American Saddlebred, American Quarter Horse, and Warmblood breeds such as the Trakehner. Arabian bloodlines have also influenced the development of the Welsh Pony, the Australian Stock Horse, Percheron draft horse, Appaloosa, and the Colorado Ranger Horse.

Today, people cross Arabians with other breeds to add refinement, endurance, agility and beauty. In the USA, Half-Arabians have their own registry within the Arabian Horse Association, which includes a special section for Anglo-Arabians (Arabian-Thoroughbred crosses). Some crosses originally registered only as Half-Arabians became popular enough to have their own breed registry, including the National Show Horse (an Arabian-Saddlebred cross), the Quarab (Arabian-Quarter Horse), the Pintabian the Welara (Arabian-Welsh Pony), and the Morab (Arabian-Morgan). In addition, some Arabians and Half Arabians have been approved for breeding by some Warmblood registries, particularly the Trakehner registry.

There is intense debate over the role the Arabian played in the development of other light horse breeds. Before DNA-based research developed, one hypothesis, based on body types and conformation, suggested the light, "dry", oriental horse adapted to the desert climate had developed prior to domestication; DNA studies of multiple horse breeds now suggest that while domesticated horses arose from multiple mare lines, there is very little variability in the Y-chromosome between breeds. Following domestication of the horse, due to the location of the Middle East as a crossroads of the ancient world, and relatively near the earliest locations of domestication, oriental horses spread throughout Europe and Asia both in ancient and modern times. There is little doubt that humans crossed "oriental" blood on that of other types to create light riding horses; the only actual questions are at what point the "oriental" prototype could be called an "Arabian", how much Arabian blood was mixed with local animals, and at what point in history.

For some breeds, such as the Thoroughbred, Arabian influence of specific animals is documented in written stud books. For older breeds, dating the influx of Arabian ancestry is more difficult. For example, while outside cultures, and the horses they brought with them, influenced the predecessor to the Iberian horse in both the time of Ancient Rome and again with the Islamic invasions of the 8th century, it is difficult to trace precise details of the journeys taken by waves of conquerors and their horses as they traveled from the Middle East to North Africa and across Gibraltar to southern Europe. Mitochondrial DNA studies of modern Andalusian horses of the Iberian peninsula and Barb horses of North Africa present convincing evidence that both breeds crossed the Strait of Gibraltar and influenced one another. Though these studies did not compare Andalusian and Barb mtDNA to that of Arabian horses, there is evidence that horses resembling Arabians, whether before or after the breed was called an "Arabian", were part of this genetic mix. Arabians and Barbs, though probably related to one another, are quite different in appearance, and horses of both Arabian and Barb type were present in the Muslim armies that occupied Europe. There is also historical documentation that Islamic invaders raised Arabian horses in Spain prior to the Reconquista; the Spanish also documented imports of Arabian horses in 1847, 1884 and 1885 that were used to improve existing Spanish stock and revive declining equine populations.
