Animal-powered Transport
A working animal is an animal, usually domestication, domesticated, that is kept by humans and trained to perform tasks. Some are used for their physical strength (e.g. oxen and draft horses) or for transportation (e.g. riding horses and camels), while others are service animals trained to execute certain specialized tasks (e.g. hunting dog, hunting and guide dogs, messenger pigeons, and cormorant fishing, fishing cormorants). They may also be used for milking or herding. Some, at the end of their working lives, may also be used for meat or leather. The history of working animals may predate agriculture as dogs were used by hunter-gatherer ancestors; around the world, millions of animals work in relationship with their owners. Domesticated species are often breed, bred for different uses and conditions, especially horses and working dogs. Working animals are usually raised on farms, though some are still captured from the wild, such as dolphins and some Asian elephants. People ...

Bullock Team
A bullock cart or ox cart (sometimes called a Carriage#Bullock carriage, bullock carriage when carrying people in particular) is a two-wheeled or four-wheeled vehicle pulled by oxen. It is a means of transportation used since ancient times in many parts of the world. They are still used today where modern vehicles are too expensive or less suitable for the local infrastructure. Used especially for carrying goods, the bullock cart is pulled by one or several oxen. The cart is attached to an ox team by a special chain attached to yokes, but a rope may also be used for one or two animals. The driver, and any other passengers, sit on the front of the cart, while load (if there is any) is placed in the back. Traditionally, the cargo has been agrarian goods and lumber. History The first indications of the use of a wagon (cart tracks, incisions, model wheels) are dated to around 4400 BC. The oldest wooden wheels usable for transport were found in southern Russia and dated to 3325 ± 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Working Dog
A working dog is a dog used to perform practical tasks, as opposed to pet or companion dogs. Definitions vary on what a working dog is, they are sometimes described as any dog trained for and employed in meaningful work; other times as any dog whose breed heritage or physical characteristics lend itself to working irrespective of an individual animal's training or employment; and other times again it is used as a synonym for herding dog. Working dog types Roles performed by dogs that sometimes sees them classified as working dogs include: * Assistance or service dog trained to help a disabled person in some way, such as guiding a visually impaired person, providing mobility assistance, and psychiatric service. Often overlap with Therapy dog used to provide companionship or to help people rehabilitate from injuries. * Carriage dog historically used to provide protection to carriage passengers or merchandise * Detection dog or sniffer dog, trained to detect for exa ...

Pack Animal
A pack animal, also known as a sumpter animal or beast of burden, is a working animal used to transport goods or materials by carrying them, usually on its back. Domestic animals of many species are used in this way, among them alpacas, Bactrian camels, donkeys, dromedaries, gayal, goats, horses, llamas, mules, reindeer, water buffaloes and yaks. Diversity Traditional pack animals include ungulates such as camels, the domestic yak, reindeer, goats, water buffaloes, and llama, and domesticated members of the horse family including horses, donkeys, and mules. Occasionally, dogs can be used to carry small loads. Pack animals by region * Arctic – reindeer and sled dogs * Central Africa and Southern Africa – oxen, mules, donkeys * Eurasia – donkeys, oxen, horses, mules ** Central Asia – Bactrian camels, yaks, horses, mules, donkeys ** South and Southeast Asia – water buffaloes, yaks, Asian elephants * North America – horses, mules, don ...

Carrier Pigeon
The homing pigeon is a variety of domestic pigeon (''Columba livia domestica''), selectively bred for its ability to find its way home over extremely long distances. Because of this skill, homing pigeons were used to carry messages, a practice referred to as " pigeon post". Until the introduction of telephones, they were used commercially to deliver communication; when used during wars, they were called "war pigeons". The homing pigeon is also called a mail pigeon or messenger, and colloquially a homer. Perhaps most commonly, the homing pigeon is called a carrier pigeon; this nomenclature can be confusing, though, since it is distinct from the English carrier, an ancient breed of fancy pigeon. Modern-day homing pigeons do have English carrier blood in them because they are in part descendants of the old-style carriers. The domestic pigeon is derived from the wild rock dove (''Columba livia'' sspp.); the rock dove has an innate homing ability, meaning that it will generally r ...

Wool
Wool is the textile fiber obtained from sheep and other mammals, especially goats, rabbits, and camelids. The term may also refer to inorganic materials, such as mineral wool and glass wool, that have some properties similar to animal wool. As an animal fiber, wool consists of protein together with a small percentage of lipids. This makes it chemically quite distinct from cotton and other plant fibers, which are mainly cellulose. Characteristics Wool is produced by follicles which are small cells located in the skin. These follicles are located in the upper layer of the skin called the epidermis and push down into the second skin layer called the dermis as the wool fibers grow. Follicles can be classed as either primary or secondary follicles. Primary follicles produce three types of fiber: kemp, medullated fibers, and true wool fibers. Secondary follicles only produce true wool fibers. Medullated fibers share nearly identical characteristics to hair and are long but ...

Hide (skin)
A hide or skin is an animal skin treated for human use. The word "hide" is related to the German word , which means skin. The industry defines hides as "skins" of large animals ''e.g''. cow, buffalo; while skins refer to "skins" of smaller animals: goat, sheep, deer, pig, fish, alligator, snake, etc. Common commercial hides include leather from cattle and other livestock animals, buckskin, alligator skin and snake skin. All are used for shoes, clothes, leather bags, belts, or other fashion accessories. Leather is also used in cars, upholstery, interior decorating, horse tack and harnesses. Skins are sometimes still gathered from hunting and processed at a domestic or artisanal level but most leather making is now industrialized and large-scale. Various tannins are used for this purpose. Hides are also used as processed chews for dogs or other pets. The term "skin" is sometimes expanded to include furs, which are harvested from various species, including cat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal Training
Animal training is the act of teaching animals specific responses to specific conditions or stimuli. Training may be for purposes such as companionship, detection, protection, and entertainment. The type of training an animal receives will vary depending on the training method used, and the purpose for training the animal. For example, a seeing eye dog will be trained to achieve a different goal than a wild animal in a circus. In some countries animal trainer certification bodies exist. They do not share consistent goals or requirements; they do not prevent someone from practicing as an animal trainer nor using the title. Similarly, the United States does not require animal trainers to have any specific certification. An animal trainer should consider the natural behaviors of the animal and aim to modify behaviors through a basic system of reward and punishment. Methods The behavioral approach Principles During training, an animal trainer can administer one of four pot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disabled
Disability is the experience of any condition that makes it more difficult for a person to do certain activities or have equitable access within a given society. Disabilities may be cognitive, developmental, intellectual, mental, physical, sensory, or a combination of multiple factors. Disabilities can be present from birth or can be acquired during a person's lifetime. Historically, disabilities have only been recognized based on a narrow set of criteria—however, disabilities are not binary and can be present in unique characteristics depending on the individual. A disability may be readily visible, or invisible in nature. The United Nations Convention on the Rights of Persons with Disabilities defines disability as including: Disabilities have been perceived differently throughout history, through a variety of different theoretical lenses. There are two main models that attempt to explain disability in our society: the medical model and the social model. The me ...

Monkey
Monkey is a common name that may refer to most mammals of the infraorder Simiiformes, also known as simians. Traditionally, all animals in the group now known as simians are counted as monkeys except the apes. Thus monkeys, in that sense, constitute an incomplete paraphyletic grouping; alternatively, if apes (Hominoidea) are included, ''monkeys'' and ''simians'' are synonyms. In 1812, Étienne Geoffroy grouped the apes and the Cercopithecidae group of monkeys together and established the name Catarrhini, "Old World monkeys" ("''singes de l'Ancien Monde''" in French). The extant sister of the Catarrhini in the monkey ("singes") group is the Platyrrhini (New World monkeys). Some nine million years before the divergence between the Cercopithecidae and the apes, the Platyrrhini emerged within "monkeys" by migration to South America likely by ocean. Apes are thus deep in the tree of extant and extinct monkeys, and any of the apes is distinctly closer related to the Cercopith ...

Donkey
The donkey or ass is a domesticated equine. It derives from the African wild ass, ''Equus africanus'', and may be classified either as a subspecies thereof, ''Equus africanus asinus'', or as a separate species, ''Equus asinus''. It was domesticated in Africa some years ago, and has been used mainly as a working animal since that time. There are more than 40 million donkeys in the world, mostly in underdeveloped countries, where they are used principally as Working animal, draught or pack animal, pack animals. While working donkeys are often associated with those living at or below subsistence, small numbers of donkeys or asses are kept for breeding, as pets, and for livestock protection in developed countries. An adult male donkey is a ''jack'' or ''jackass'', an adult female is a ''jenny'' or ''jennet'', and an immature donkey of either sex is a ''foal''. Jacks are often mated with horse, female horses (mares) to produce ''mule, mules''; the less common hybrid of a stalli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Industrialisation
Industrialisation ( UK) or industrialization ( US) is the period of social and economic change that transforms a human group from an agrarian society into an industrial society. This involves an extensive reorganisation of an economy for the purpose of manufacturing. Industrialisation is associated with increase of polluting industries heavily dependent on fossil fuels. With the increasing focus on sustainable development and green industrial policy practices, industrialisation increasingly includes technological leapfrogging, with direct investment in more advanced, cleaner technologies. The reorganisation of the economy has many unintended consequences both economically and socially. As industrial workers' incomes rise, markets for consumer goods and services of all kinds tend to expand and provide a further stimulus to industrial investment and economic growth. Moreover, family structures tend to shift as extended families tend to no longer live together in one hous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
