CattleCattle (Bos taurus) are large, domesticated, bovid ungulates. They are prominent modern members of the subfamily Bovinae and the most widespread species of the genus Bos. Mature female cattle are referred to as cows and mature male cattle are referred to as bulls. Colloquially, young female cattle (heifers), young male cattle (bullocks), and castrated male cattle (steers) are also referred to as "cows". Cattle are commonly raised as livestock for meat (beef or veal, see beef cattle), for milk (see dairy cattle), and for hides, which are used to make leather.
Working animalA working animal is an animal, usually domesticated, that is kept by humans and trained to perform tasks instead of being slaughtered to harvest animal products. 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 and guide dogs, messenger pigeons and fishing cormorants). They may also be used for milking or herding.
PloughA plough or plow (US; both plaʊ) is a farm tool for loosening or turning the soil before sowing seed or planting. Ploughs were traditionally drawn by oxen and horses but in modern farms are drawn by tractors. A plough may have a wooden, iron or steel frame with a blade attached to cut and loosen the soil. It has been fundamental to farming for most of history. The earliest ploughs had no wheels; such a plough was known to the Romans as an aratrum. Celtic peoples first came to use wheeled ploughs in the Roman era.
CartA cart or dray (Australia and New Zealand) is a vehicle designed for transport, using two wheels and normally pulled by one or a pair of draught animals. A handcart is pulled or pushed by one or more people. It is different from the flatbed trolley also known as a dray, (for freight) or wagon, which is a heavy transport vehicle with four wheels and typically two or more humans. Over time, the term "cart" has come to mean nearly any small conveyance, including shopping carts, golf carts, gokarts, and UTVs, without regard to number of wheels, load carried, or means of propulsion.
NeuteringNeutering, from the Latin neuter ('of neither sex'), is the removal of a non-human animal's reproductive organ, either all of it or a considerably large part. The male-specific term is castration, while spaying is usually reserved for female animals. Colloquially, both terms are often referred to as fixing. In male horses, castrating is referred to as gelding. An animal that has not been neutered is sometimes referred to as entire or intact. Neutering is the most common method for animal sterilization.
Selective breedingSelective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. Domesticated animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as varieties, cultigens, cultivars, or breeds.
