The Merino is a breed or group of breeds of domestic sheep, characterised by very fine soft wool. It was established in the Iberian Peninsula (modern Spain and Portugal) near the end of the Middle Ages, and was for several centuries kept as a strict Spanish monopoly; exports of the breed were not allowed, and those who tried risked capital punishment. During the eighteenth century, flocks were sent to the courts of a number of European countries, including France (where they developed into the Rambouillet), Hungary, the Netherlands, Prussia, Saxony and Sweden.
The Merino subsequently spread to many parts of the world, including South Africa, Australia, and New Zealand. They are presently common in South Africa. Numerous recognised breeds, strains and variants have developed from the original type; these include, among others, the American Merino and Delaine Merino in the Americas, the Australian Merino, Booroola Merino and Peppin Merino in Oceania, and the Gentile di Puglia, Merinolandschaf and Rambouillet in Europe.
The Australian Poll Merino is a polled livestock (hornless) variant. Rams of other Merino breeds have long, spiral horns which grow close to the head, while ewes are usually hornless.
Two suggested origins for the Spanish word merino are given in:
Sheep were relatively unimportant in the Islamic Caliphate of Córdoba, and there is no record of extensive transhumance before the caliphate's fall in the 1030s. The Marinids, when a nomadic Zenata Berber tribe, held extensive sheep flocks in what is now Morocco, and its leaders who formed the Marinid Sultanate militarily intervened in southern Spain, supporting the Emirate of Granada several times in the late 13th and early 14th centuries. Although they may possibly have brought new breeds of sheep into Spain, there is no definite evidence that the Marinids did bring extensive flocks to Spain. As the Marinids arrived as an intervening military force, they were hardly in a position to protect extensive flocks and practice selective breeding.
The third theory, that the Merino breed was created in Spain over several centuries with a strong Spanish heritage, rather than simply being an existing North African strain that was imported in the 12th century, is supported both by recent genetic studies and the absence of definitive Merino wool before the 15th century. The predominant native sheep breed in Spain from pre-Roman times was the Churra, a homogeneous group closely related to European sheep types north of the Pyrenees and bred mainly for meat and milk, with coarse, coloured wool. Churro wool had little value, except where its ewes had been crossed with a fine wool breed from southern Italy in Roman times. Genetic studies have shown that the Merino breed most probably developed by the crossing of churro ewes with a variety of rams of other breeds at different periods, including Italian rams in Roman times, North African rams in the medieval period, and English rams from fine-wool breeds in the 15th century.
Although Spain exported wool to England, the Low Countries and Italy in the 13th and 14th centuries, it was only used to make cheap cloth. The earliest evidence of fine Spanish wool exports was to Italy in the 1390s and Flanders in the 1420s, although in both cases fine English wool was preferred. Spain became noted for its fine wool (spinning count between 60s and 64s) in the late 15th century, and by the mid-16th century its Merino wool was acknowledged to equal that of the finest English wools.
The earliest documentary evidence for Merino wools in Italy dates to the 1400s, and in the 1420s and 1430s, Merino wools were being mixed with fine English wool in some towns in the Low Countries to produce high quality cloth. However, it was only in the mid-16th century that the most expensive grades of cloth could be made entirely from Merino wool, after its quality had improved to equal that of the finest English wools, which were in increasingly short supply at that time.
Preserved medieval woollen fabrics from the Low Countries show that, before the 16th century, only the best quality English wools had a fineness of staple comparable to modern Merino wool. The wide range of Spanish wools produced in the 13th and early 14th centuries were mostly used domestically for cheap, coarse and light fabrics, and were not Merino wools. Later in the 14th century, similar non-Merino wools were exported from the northern Castilian ports of San Sebastián, Santander, and Bilbao to England and the Low Countries to make coarse, cheap cloth. The quality of Spanish wools exported increased markedly in the late 15th century, as did their price, promoted by the efforts of the monarchs Ferdinand and Isabella to improve quality.
Spain built up a virtual monopoly in fine wool exports in the final decades of the 15th century and in the 16th century, creating a substantial source of income for Castile. In part, this was because most English wool was woven and made into textile goods within England by the 16th century, rather than being exported.
Many of the Castillian Merino flocks were owned by nobility or the church, although Alfonso X realised that granting the urban elites of the towns of Old Castile and León transhumant rights would create an additional source of royal income and counteract the power of the privileged orders. During the late 15th, 16th and early 17th century, two-thirds of the sheep migrating annually were held in flocks of less than 100 sheep and very few flocks exceeded 1,000 sheep. By the 18th century, there were fewer small owners, and several owners held flocks of more than 20,000 sheep, but owners of small to moderately sized flocks remained, and the Mesta was never simply a combination of large owners.
The transhumant sheep grazed the southern Spanish plains in winter and the northern highlands in summer. The annual migrations to and from Castile and León, where the sheep were owned and where they had summer pasturage, was organised and controlled by the Mesta along designated sheep-walks, or cañadas reales and arranged for suitable grazing, water and rest stops in these routes, and for shearing when the flocks started their return north.
The three Merino strains that founded the world's Merino flocks are the Royal Escurial flocks, the Negretti and the Paula. Among Merino bloodlines stemming from Vermont in the US, three historical studs were highly important: Infantado, Montarcos and Aguires. In recent times, Merino and breeds deriving from Merino stocks have spread worldwide. However, there has been a substantial decline in the numbers of several European Merino breeds, which are now considered to be endangered breeds and are no longer the subject of genetic improvement. In Spain, there are now two populations, the commercial Merino flocks, most common in the province of Extremadura and an "historical" Spanish Merino strain, developed and conserved in a breeding centre near Cordoba. The commercial Merino flocks show considerable genetic diversity, probably because of their cross-breeding with non-Spanish Merino-derived breeds since the 1960s, to create a strain more suitable for meat production. The historical Spanish strain, bred from animals selected from the main traditional Spanish genetic lines to ensure the conservation of a purebred lineage, exhibits signs of inbreeding.
Before the 18th century, the export of Merinos from Spain was a crime punishable by death. In the 18th century, small exportation of Merinos from Spain and local sheep were used as the foundation of Merino flocks in other countries. In 1723, some were exported to Sweden, but the first major consignment of Escurials was sent by Charles III of Spain to his cousin, Prince Xavier the Elector of Saxony, in 1765. Further exportation of Escurials to Saxony occurred in 1774, to Hungary in 1775 and to Prussia in 1786. Later in 1786, Louis XVI of France received 366 sheep selected from 10 different cañadas; these founded the stud at the Royal Farm at Rambouillet. In addition to the fine wool breeds mentioned, other breeds derived from Merino stocks were developed to produce mutton, including the French Ile de France and Berrichon du Cher breeds. Merino sheep were also sent to Eastern Europe where their breeding began in Hungary in 1774 The Rambouillet stud enjoyed some undisclosed genetic development with some English long-wool genes contributing to the size and wool-type of the French sheep. Through one ram in particular named Emperor – imported to Australia in 1860 by the Peppin Merino of Wanganella, New South Wales – the Rambouillet stud had an enormous influence on the development of the Australian Merino.
Sir Joseph Banks procured two rams and four ewes in 1787 by way of Portugal, and in 1792 purchased 40 Negrettis for King George III to found the royal flock at Kew. In 1808, 2000 Paulas were imported. The King of Spain also gave some Escurials to the Dutch government in 1790; these thrived in the Dutch Cape Colony (South Africa). In 1788, John MacArthur, from the Clan Arthur (or MacArthur Clan) introduced Merinos to Australia from South Africa.
From 1765, the Germans in Saxony crossed the Spanish Merino with the Saxon sheep to develop a dense, fine type of Merino (spinning count between 70s and 80s) adapted to its new environment. From 1778, the Saxon breeding center was operated in the Folwark Stolpen. It was administered from 1796 by Johann Gottfried Nake, who developed scientific crossing methods to further improve the Saxon Merino. By 1802, the region had four million Saxon Merino sheep, and was becoming the centre for stud Merino breeding, and German wool was considered to be the finest in the world.
In 1802, Colonel David Humphreys, United States Ambassador to Spain, introduced the Vermont strain into North America with an importation of 21 rams and 70 ewes from Portugal and a further importation of 100 Infantado Merinos in 1808. The British embargo on wool and wool clothing exports to the U.S. before the 1812 British/U.S. war led to a "Merino Craze", with William Jarvis of the Diplomatic Corps importing at least 3,500 sheep between 1809 and 1811 through Portugal.
The Napoleonic Wars (1793–1813) almost destroyed the Spanish Merino industry. The old cabañas or flocks were dispersed or slaughtered. From 1810 onwards, the Merino scene shifted to Germany, the United States and Australia. Saxony lifted the export ban on living Merinos after the Napoleonic wars. Highly decorated Saxon sheep breeder Nake from Rennersdorf had established a private sheep farm in Kleindrebnitz in 1811, but ironically after the success of his sheep export to Australia and Russia, failed with his own undertaking.
In 1797, Governor King, Colonel Patterson, Captain Waterhouse and Kent purchased sheep in Cape Town from the widow of Colonel Gordon, commander of the Dutch garrison. When Waterhouse landed in Sydney, he sold his sheep to Captain John MacArthur, Samuel Marsden and Captain William Cox.
Macarthur pioneered the introduction of Saxon Merinos with importation from the Electoral flock in 1812. The first Australian wool boom occurred in 1813, when the Great Dividing Range was crossed. During the 1820s, interest in Merino sheep increased. MacArthur showed and sold 39 rams in October 1820, grossing £510/16/5.The Australian Merino, Charles Massey, Viking O'Neil, South Yarra, 1990, p.62 In 1823, at the first sheep show held in Australia, a gold medal was awarded to W. Riley ('Raby') for importing the most Saxons; W. Riley also imported cashmere goats into Australia.
The Age in 1908 described Eliza Furlong as someone who had 'notably stimulated and largely helped to mould the prosperity of an entire state and her name deserved to live for all time in our history' (reprinted Wagga Wagga Daily Advertiser 27 January 1989).Mary S. Ramsay, 'Forlong, Eliza (1784 - 1859)', Australian Dictionary of Biography, Supplementary Volume, Melbourne University Press, 2005, pp 130-131.
The federation drought (1901–1903) reduced the number of Australian sheep from 72 to 53 million and ended the Vermont era. The Peppin and Murray blood strain became dominant in the pastoral and wheat zones of Australia.
New Zealand banned mulesing on 1 October 2018. Animal Welfare (Care and Procedures) Regulations 2018
Merino has been domesticated and bred in ways that would not allow them to survive well without regular shearing by their owners. They must be shorn at least once a year because their wool does not stop growing. If this is neglected, the overabundance of wool can cause heat stress, mobility issues, and even blindness. To mitigate parasites, Mulesing is carried out. It is a painful procedure where skin is cut away without pain relief to stop the buildup of parasites in the folds of the skin.
