Sorraia Horse
| Country Of Origin | Portugal |
| History and Background | The Sorraia is a rare breed of horse indigenous to the portion of the Iberian peninsula, in the Sorraia River basin, in Portugal. The Sorraia is known for its primitive features, including a convex profile and dun coloring with primitive markings. Concerning its origins, a theory has been advanced by some authors that the Sorraia is a descendant of primitive horses belonging to the naturally occurring wild fauna of Southern Iberia. Studies are currently ongoing to discover the relationship between the Sorraia and various wild horse types, as well as its relationship with other breeds from the Iberian Peninsula and Northern Africa. Members of the breed are small, but hardy and well-adapted to harsh conditions. They were occasionally captured and used by native farmers for centuries, and a remnant population of these nearly extinct horses was discovered by a Portuguese zoologist in the early 20th century. Today, the Sorraia has become the focus of preservation efforts, with European scientists leading the way and enthusiasts from several countries forming projects and establishing herds to assist in the re-establishment of this breed from its current endangered status. Genetics; The relationship between the Sorraia and other breeds remains largely undetermined, as is its relationship to the wild horse subspecies, the Tarpan and the Przewalski's Horse. The Sorraia originally developed in the southern part of the Iberian peninsula. d'Andrade hypothesized that the Sorraia would be the ancestor of the Southern Iberian breeds. Morphologically, scientists place the Sorraia as closely related to the Gallego and the Asturcon, but genetic studies using mitochondrial DNA show that the Sorraia forms a cluster that is largely separated from most Iberian breeds. Some evidence links this cluster with Konik and domestic Mongolian horses. At the same time, one of the maternal lineages is shared with the Lusitano. Genetic evidence has not supported an hypothesis that the Sorraia is related to the Barb horse, an African breed introduced to Iberia by the Moors. Multiple authors have suggested that the Sorraia might be a descendant of the Tarpan based on shared morphological features, principally the typical color of its coat. Other authors simply state that the Sorraia has "evident primitive characteristics", although they do not refer to a specific ancestor. However, there have been no genetic studies comparing the Sorraia with the Tarpan, and similarity of external morphology is an unreliable measure of relatedness. Genetic studies to date have been inconclusive about the closest relative of the Sorraia. On one hand, studies using mitochondrial DNA showed a relationship with the Przewalski's Horse, in that Przewalski's Horse has a unique haplotype (A2) not found in domestic horses, which differs by just one single nucleotide from one of the major Sorraia haplotypes (JSO41, later A7). In comparison, genetic distances within the domestic horse are as large as 11 nucleotide differences. However, this relationship with the Przewalski's Horse was contradicted in another study using microsatellite data that showed that the genetic distance between the Prewalski's Horse and the Sorraia was the largest. Such conflicting results can arise when a population passes through a genetic bottleneck, and evidence suggests that the Sorraia, among other rare breeds, has recently passed through a bottleneck, effectively obscuring the position of this breed in the family tree of the domestic horse. Thus, the morphological, physiological, and cultural characteristics of the Sorraia are the subject of continued study to better understand the relationship between various Iberian horse breeds and wild horse subspecies. History; Although it is known that the Sorraia developed in the southern part of the Iberian peninsula, the breed was isolated and unknown to science until the 20th century. Despite the lack of documentation, attempts have been made to reconstruct its history. Paleolithic parietal art images in the region depict equines with a distinct likeness to the Sorraia, with similar zebra-like markings. Analysis of mtDNA has been performed on Mustangs in the western United States that show similar mtDNA patterns between some Mustangs and the Sorraia breed. Spanish conquistadors took Iberian horses, some of whom closely resembled the modern-day Sorraia, to the Americas in their conquests, probably as pack animals. Similarities between the Sorraia and several North and South American breeds are shown in the dun and grullo coloring and various physical characteristics. This evidence suggests that the Sorraia, their ancestors, or other horses with similar features, may have had a long history in the Iberian region and a role in the creation of American breeds. Otherwise, the Sorraia breed was lost to history until 1920, when Portuguese zoologist and paleontologist Dr. Ruy d'Andrade first encountered the Sorraia horse during a hunting trip in the Portuguese lowlands. This remnant herd of primitive horses had continued to live a wild existence in these lowlands, which were rather inaccessible and had been used as a hunting preserve by Portuguese royalty until the early 1900s. At the time of d'Andrade's initial meeting the breed, the horses were ill-regarded by native farmers, although they were considered hardy native fauna that lived off of the uncultivated lands and salt marshes in the local river valleys. For centuries, peasant farmers of the area would occasionally capture the horses and use them for agricultural work, including threshing grain and herding bulls. In the 1920s and 1930s, as mechanization became more prevalent, both wild and domesticated breeding stock diminished to almost nothing, and d'Andrade, along with his son Fernando, encouraged the conservation of the breed. In 1937, d'Andrade began a small herd of his own with five stallions and seven mares from horses obtained near Coruche, Portugal. All Sorraias currently in captivity descend from these original horses obtained by d'Andrade, and it is believed that the remnant wild herds of the breed died out soon after. These horses were kept in a habitat similar to their native one. In 1975, two other farms took up the Sorraia's cause and acquired small herds to help with conservation. In 1976, three stallions and three mares were imported to Germany from Portugal to begin a sub-population there. In March 2004, a small breeding herd of Sorraia horses was released on the estate of a private land owner who dedicated a portion of his property so that these horses could live completely wild, as did their ancestors. The refuge created for them is in the Vale de Zebro region of south western Portugal, one of places so named because this is where the Sorraia's predecessors dwelt. Two Sorraia stallions were imported to the United States in the early 21st century. In 2006, another Sorraia stallion was imported to Canada where a Sorraia Mustang Preserve has been established on Manitoulin Island in Ontario. Unrelated to existing preservation efforts which work in conjunction with the Sorraia Mustang Studbook, another project by a consortium of breeders in the United States is attempting to establish a separate network and studbook. These breeders have gathered Spanish Mustangs that through mtDNA testing show a genetic relationship with the Sorraia and are breeding them according to both genotype and phenotype in an attempt to help preserve what they are calling the "American Sorraia". Today, the breed is nearly extinct, with fewer than 200 horses existing as of 2007, including around 80 breeding mares. The Food and Agriculture Organization considers it to be maintaining critical risk status. The first studbook was published in 2004, dedicated to maintaining a written record of the bloodlines of the Sorraia. Sorraias are present mainly in Portugal, with a small population in Germany. While not bred for a specific use, the Sorraia horses are versatile and have been used in herding bulls, dressage riding and light harness. Naming; Dr. Ruy d'Andrade gave the breed their name of "Sorraia". D'Andrade took the name from the Sorraia River in Portugal. The breed had previously been known by the local Portuguese as "zebro" or "zebra", due to their markings. In the time of Christopher Columbus, the Sorraia was also known as the Marismeño, but the Sorraia and the Marismeño have evolved into two different breeds over time. Today, the name Marismeño refers to a population of semiferal horses living in Doñana Natural Park in Spain. |
| Use Today | Riding horse, Pack horse |
| Height | 14.1 and 14.3 hands (57 and 59 inches, 145 and 150 cm) |
| Colour | Dun |
| Characteristics | The head tends to be large, the profile convex, and the ears long. The neck is slender and long, the withers high, and the croup slightly sloping. The legs are strong, with long pasterns and well-proportioned hooves. These horses have good endurance and are easy keepers, thriving on relatively little fodder. On adult horses, the lay of the hair can create the appearance of stripes or "barring" on the neck and chest. Also due to the lay of the hair, newborn foals can appear to have stripes all over, reminiscent of zebra stripes. The breed standard refers to this as "hair stroke". |
| Personality and Temperament | They have a reputation for being independent of temperament, but tractable. |
