The Colonial Spanish horse is the term, popularized by Dr. D. Philip Sponenberg, for a group of horse breeds descended from the original Iberian horse stock brought from Spain to the Americas.[1] The ancestral type from which these horses descend was a product of the horse populations that blended between the Iberian horse and the North African Barb.[2] The term encompasses many strains or breeds now found primarily in North America. The status of the Colonial Spanish Horse is considered threatened overall with seven individual strains specifically called out.[3][a] The horses are registered by several entities.

The Colonial Spanish Horse is not synonymous with the Spanish Mustang, the name given to a breed derived from the first concerted effort of conservationists in the United States to preserve horses of Colonial Spanish Type.[1] Colonial Spanish Horse type and blood-markers have been found in some mustangs. Small groups of horses of Colonial Spanish Horse type have been located in various groups of ranch-bred, mission, and Native American horses, mostly among those in private ownership.[1]

Characteristics[edit]

Colonial Spanish Horses are generally small; the usual height is around 14 hands (56 inches, 142 cm), and most vary from 13.2 to 14 hands (54 to 56 inches, 137 to 142 cm). Weight varies with height, but most are around 700 to 800 pounds (320 to 360 kg). Their heads vary somewhat between long, finely made to shorter and deeper, generally having straight to concave (rarely slightly convex) foreheads and a nose that is straight or slightly convex. The muzzle is usually very fine, and from the side the upper lip is usually longer than the lower, although the teeth meet evenly. Nostrils are usually small and crescent shaped. They typically have narrow but deep chests, with the front legs leaving the body fairly close together. When viewed from the front, the front legs join the chest in an "A" shape rather than straight across as in most other modern breeds that have wider chests. The withers are usually sharp instead of low and meaty. The croup is sloped, and the tail is characteristically set low on the body. From the rear view they are usually "rafter hipped" meaning the muscling of the hip tapers up so the backbone is the highest point. Hooves are small and upright rather than flat.[4]

History in the Americas[edit]

Horses first returned to the Americas with the conquistadors, beginning with Columbus, who imported horses from Spain to the West Indies on his second voyage in 1493.[5] Domesticated horses came to the mainland with the arrival of Cortés in 1519.[6] By 1525, Cortés had imported enough horses to create a nucleus of horse-breeding in Mexico.[7] Horses arrived in South America beginning in 1531, and, by 1538, Florida, and scattered throughout the Americas. By one estimate there were at least 10,000 free-roaming horses in Mexico by 1553.[2]

In 2010, Colonial Spanish Mustang was voted Official State Horse of North Carolina.[8]

Modern horses[edit]

Many gaited horse and stock horse breeds in the United States descend from Spanish horses,[4] but only a few bloodlines are considered to be near-pure descendants of original Spanish stock. Though many are described as horse breeds, it can be debated they are separate breeds or multiple strains of a single large breed. The Livestock Conservancy lists them as one breed, but also calls them "a group of closely related breeds"[4] Various bloodlines or groups of Colonial Spanish Horses are registered a number of different Associations.[1]

Although it is a widely held belief that modern Mustangs descend from the original Spanish mustangs, genetic analysis supports "the hypothesis that the free-ranging horses in the Great Basin descend from escaped or released domestic draft, saddle, and cavalry animals."[9] but where they have been found to have descended from the original Spanish horses, the Bureau of Land Management (BLM) and other agencies attempt to preserve them.[1] Blood typing, along with phenotype and historical documentation have been used to confirm significant Spanish ancestry of a few BLM managed herds.[10] In 1985, the BLM awarded a grant to the University of California, Davis, to conduct a three-year study on Mustang genetics, including the percentage of original (Spanish) mustang blood.[11] Drs. Ann T. Bowling and R. W. Touchberry did not find much evidence of Spanish genetics in the Great Basin horses tested, but follow up work by Dr. Gus Cothran, then of University of Kentucky, carried on the study and found Spanish markers in the Pryor Mountain and Cerbat herds outside the Great Basin, and Sulphur Springs herd within it,[12] later confirming the findings for the Sulphur Springs herd through mtDNA sequencing analysis.[2][b] Sponenberg has confirmed that the four herds listed below meet the qualifications of Colonial Spanish Horses.[1]

Colonial Spanish Horses includes numerous strains, including:

A number of breeds in Latin America with Iberian DNA markers are of Spanish type and origin.[2][c] Many of these breeds come from different foundation bloodstock from horses in North America,[1] and some have haplotypes not found in North America.[2]

Notes[edit]

  1. ^ Those called out are the Baca-Chica, Banker Horse, Choctaw, Florida Cracker, Marsh Tacky, Santa Cruz, and Wilbur-Cruce.[3]
  2. ^ Cothran may have found Spanish markers in other herds listed by the BLM as having been determined by "genetic analysis" to be similar to Iberian breeds. However, when Cothran left Kentucky for Texas A&M University, he began using microsatellite DNA analysis to determine genetic diversity of feral herds rather than blood typing, but the DNA analysis was less accurate in determining ancestry.[12] Some breeders and horse associations have used blood typing results to prove or disprove horses are of Spanish ancestry, but Sponenberg urges caution, noting that some horses of Spanish type may not carry the expected Iberian blood types. Conversely, some horses that lack Spanish type, such as certain strains of the American Quarter Horse, may have blood markers but not the proper phenotype.[1]
  3. ^ This include the Argentine Criollo, Brazilian Criollo, Campolina, Chilean Criollo, Chilote, Mangalarga, Mangalarga Marchador, Pantaneiro, Paso Fino, Peruvian Paso, and Venezuelan Spanish.[2]
