Context paragraphs:
Mane Minister: Mane Minister (foaled 1988 in Kentucky) is an American Thoroughbred racehorse best remembered as the first horse to finish third in all three of the U.S. Triple Crown races.  Bred by Normandy Farm in Lexington, Kentucky, he was out of the mare Lacework, whose sire was In Reality, winner of the 1967 Florida Derby and the leading sire of two-year-olds in 1977.  Mane Minister's sire was Deputy Minister, the 1981 Canadian Horse of the Year and the Leading sire in North America in 1997 and 1998.  Deputy Minister, his sire Vice Regent, and his grandsire Northern Dancer are all Canadian Horse Racing Hall of Fame inductees.

Palfrey: A palfrey is a type of horse that was highly valued as a riding horse in the Middle Ages.  It was a lighter-weight horse, usually a smooth gaited one that could amble, suitable for riding over long distances.  Palfreys were not a specific breed as horse breeds are understood today.

Mérens horse: The Mérens or Cheval de Mérens, still occasionally referred to by the older name of Ariégeois pony, is a small, rustic horse native to the Pyrenees and Ariégeois mountains of southern France, where the Ariège River flows, and northern Spain, near Andorra.  Two general types, a small, light traditional mountain horse and a taller, sportier modern type, are found.  Always black in color, Mérens must meet strict physical standards in order to be registered in the stud book.  The breed is known for its sure-footedness on mountain terrain, as well as for its endurance, hardiness and docility.  The French breed registry organizes regional offices, and partners with other national organizations in Europe to preserve and promote the breed.  The organization enforces rigorous selection of breeding stock, with a goal of increasing quality in the breed.  In the past, the Mérens was used for farm work, draft work and as pack horses. Today it is mainly used as a saddle horse, although some members of the breed have been successful in carriage driving.  Many Mérens are taken on an annual transhumance (seasonal migration), in which they are moved higher in the mountains during the summer and into the valleys for the winter.  An old practice, it fell into disfavor, but has recently re-emerged.

Nonius horse: The Nonius (Hungarian: "Nóniusz" ) is a Hungarian horse breed named after its Anglo-Norman foundation sire.  Generally dark in color, it is a muscular and heavy-boned breed, similar in type to other light draft and driving horses.  The breed was developed at the Imperial Stud at Mezőhegyes, Hungary by careful linebreeding.  Originally bred to serve as a light draft and utility horse for Hungary's military, the breed became a useful agricultural horse during the 20th century.  The depredations of World War II significantly reduced the Nonius' population, and in the decades after the war, a downturn in the usage of horses in Hungary sent many members of the breed to slaughter.  Today the breed is bred by preservationists and is used in agriculture, leisure riding, and competitive driving sports.  The largest numbers of Nonius horses are still found at Mezőhegyes, with representatives in other eastern European nations as well.

Palomino rabbit: The Palomino rabbit is a breed of rabbit, normally 8-12 pounds in weight, which is generally colored gold or lynx.  It was first bred in Washington State, United States, by Mark Youngs, who wanted to make a <nowiki>"new"</nowiki> breed of rabbit.  As with the palomino horse, the rabbit gets its name from its color.

Haflinger: The Haflinger, also known as the Avelignese, is a breed of horse developed in Austria and northern Italy (namely Hafling in South Tyrol region) during the late nineteenth century.  Haflinger horses are relatively small, are always chestnut in color, have distinctive gaits described as energetic but smooth, and are well-muscled yet elegant.  The breed traces its ancestry to the Middle Ages; there are several theories for its origin.  Haflingers, developed for use in mountainous terrain, are known for their hardiness.  Their current conformation and appearance are the result of infusions of bloodlines from Arabian and various European breeds into the original native Tyrolean ponies.  The foundation sire, 249 Folie, was born in 1874; by 1904 the first breeders' cooperative was formed.  All Haflingers can trace their lineage back to Folie through one of seven bloodlines.  World Wars I and II, as well as the Great Depression, had a detrimental effect on the breed, and lower-quality animals were used at times to save the breed from extinction.  During World War II, breeders focused on horses that were shorter and more draft-like, favored by the military for use as packhorses.  The emphasis after the war shifted toward animals of increased refinement and height.

Welsh pig: The Welsh is a breed of domestic pig native to Wales.  It is a large white breed known for its hardiness in outdoor (extensive) farming, its long, pear-shaped body and its lop-ears.  The breed was first mentioned in the 1870s, and after the Howitt committee report in 1955, became the third most common sire in the United Kingdom after the Large White pig and British Landrace pig.  The Welsh pig experienced a decline in numbers in the late twentieth century because consumer demands had changed and the carcase was considered too fatty.  In 2005 the breed was considered endangered and later came under the auspices of the Rare Breeds Survival Trust.  Since then numbers have expanded somewhat, and by 2012, the registered breeding herd had increased to over 1000 animals.

Ukrainian Riding Horse: The Ukrainian Riding Horse (Ukrainian: Український верховий кінь) or Ukrainian Saddle Horse a breed developed in Ukraine after World War II to meet the ever-increasing demand for sport horses, was first bred at the Dnipropetrovsk stud.  Today, it is bred at the studs of Derkulsk, Yagonitsk, and Aleksandriisk.  The breed is well established in characteristics despite the fact that it is relatively young, due to the highly selective breeding process.

Rocky Mountain Horse: The Rocky Mountain Horse is a horse breed developed in the state of Kentucky in the United States.  Despite its name, it originated not in the Rocky Mountains, but instead in the Appalachian Mountains.  A foundation stallion, brought from the western United States to eastern Kentucky around 1890, began the Rocky Mountain type in the late 19th century.  In the mid-20th century, a stallion named Old Tobe, owned by a prominent breeder, was used to develop the modern type; today most Rocky Mountain Horses trace back to this stallion.  In 1986, the Rocky Mountain Horse Association was formed and by 2005 has registered over 12,000 horses.  The breed is known for its preferred "chocolate" coat color and flaxen mane and tail, the result of the relatively rare silver dapple gene acting on a black coat, seen in much of the population.  It also exhibits a four-beat ambling gait known as the "single-foot".  Originally developed as a multi-purpose riding, driving and light draft horse, today it is used mainly for trail riding and working cattle.

Flaxen gene: The flaxen gene is a genetic mechanism that causes the mane and tail of chestnut-colored horses to be noticeably lighter than the body coat color, often a golden blonde shade.  Certain horse breeds such as the Haflinger carry flaxen chestnut coloration as a breed trait.  It is common in chestnut-colored animals of other horse breeds that may not be exclusively chestnut.
