The chicken is a type of domesticated fowl, a subspecies of the red junglefowl. It is one of the most common and widespread domestic animals, with a total population of more than 19 billion as of 2011. There are more chickens in the world than any other bird or domesticated fowl. Humans keep chickens primarily as a source of food and, less commonly, as pets. Originally raised for cockfighting or for special ceremonies, chickens were not kept for food until the Hellenistic period.
Secretariat was an American Thoroughbred racehorse that, in 1973, became the first Triple Crown winner in 25 years. His record-breaking victory in the Belmont Stakes, which he won by 31 lengths, is widely regarded as one of the greatest races in history. During his racing career, he won five Eclipse Awards, including Horse of the Year honors at ages two and three. He was nominated to the National Museum of Racing and Hall of Fame in 1974. In the List of the Top 100 U.S. Racehorses of the 20th Century, Secretariat is second only to Man o' War, who also was a large chestnut colt given the nickname "Big Red".
Duck is the common name for a large number of species in the waterfowl family Anatidae, which also includes swans and geese. Ducks are divided among several subfamilies in the family Anatidae; they do not represent a monophyletic group but a form taxon, since swans and geese are not considered ducks. Ducks are mostly aquatic birds, mostly smaller than the swans and geese, and may be found in both fresh water and sea water.
Livestock are domesticated animals raised in an agricultural setting to produce labor and commodities such as meat, eggs, milk, fur, leather, and wool. The term is sometimes used to refer solely to those that are bred for consumption, while other times it refers only to farmed ruminants, such as cattle and goats.
A pony is a small horse. Depending on context, a pony may be a horse that is under an approximate or exact height at the withers or a small horse with a specific conformation and temperament. There are many different breeds. Compared to other horses, ponies often exhibit thicker manes, tails and overall coat, as well as proportionally shorter legs, wider barrels, heavier bone, thicker necks, and shorter heads with broader foreheads. The word pony derives from the old French poulenet, meaning foal, a young, immature horse, but this is not the modern meaning; unlike a horse foal, a pony remains small when fully grown. However, on occasion, people who are unfamiliar with horses may confuse an adult pony with a foal.
The Thoroughbred is a horse breed best known for its use in horse racing. Although the word thoroughbred is sometimes used to refer to any breed of purebred horse, it technically refers only to the Thoroughbred breed. Thoroughbreds are considered "hot-blooded" horses that are known for their agility, speed, and spirit.
The silkworm is the larva or caterpillar or imago of the domestic silkmoth, Bombyx mori. It is an economically important insect, being a primary producer of silk. A silkworm's preferred food is white mulberry leaves, though they may eat other mulberry species and even osage orange. Domestic silkmoths are closely dependent on humans for reproduction, as a result of millennia of selective breeding. Wild silkmoths are different from their domestic cousins as they have not been selectively bred; they are not as commercially viable in the production of silk.
A stallion is a male horse that has not been gelded (castrated). Stallions follow the conformation and phenotype of their breed, but within that standard, the presence of hormones such as testosterone may give stallions a thicker, "cresty" neck, as well as a somewhat more muscular physique as compared to female horses, known as mares, and castrated males, called geldings.
A draft horse (US), draught horse or dray horse, less often called a carthorse, work horse or heavy horse, is a large horse bred to be a working animal doing hard tasks such as plowing and other farm labor. There are a number of breeds, with varying characteristics, but all share common traits of strength, patience, and a docile temperament which made them indispensable to generations of pre-industrial farmers.
Guineafowl are birds of the family Numididae in the order Galliformes. They are endemic to Africa and rank among the oldest of the gallinaceous birds. Phylogenetically, they branch off from the core Galliformes after the Cracidae and before the Odontophoridae. An Eocene fossil lineage, Telecrex, has been associated with guineafowl. Telecrex inhabited Mongolia, and may have given rise to the oldest of the true Phasianids such as Ithaginis and Crossoptilon, which evolved into high-altitude montane-adapted species with the rise of the Tibetan Plateau. While modern guineafowl species are endemic to Africa, the helmeted guineafowl has been introduced widely elsewhere.
A gelding is a castrated horse or other equine, such as a donkey or a mule. Castration, as well as the elimination of hormonally-driven behavior associated with a stallion, allows a male horse to be calmer and better-behaved, making the animal quieter, gentler and potentially more suitable as an everyday working animal. The gerund and participle "gelding" and the infinitive "to geld" refer to the castration procedure itself.
Seabiscuit was a champion thoroughbred racehorse in the United States, who became the top money winning racehorse up to the 1940s, as noted in films and books. He beat the 1937 Triple-Crown winner, War Admiral, by 4 lengths in a 2-horse special at Pimlico, and was voted American Horse of the Year for 1938.
