Domestic geese (Anser anser domesticus or Anser cygnoides) are domesticated grey geese (either greylag geese or swan geese) kept as poultry for their meat, eggs, and down feathers since ancient times.

Origins and characteristics

In Europe, northern Africa, and western Asia, the original domesticated geese are derived from the greylag goose Anser anser. In eastern Asia, the original domesticated geese are derived from the swan goose Anser cygnoides; these are commonly known as Chinese geese. Both have been widely introduced in more recent times, and modern flocks in both areas (and elsewhere, such as Australia and North America) may consist of either species, and/or hybrids between them. Chinese geese may be readily distinguished from European geese by the large knob at the base of the bill, though hybrids may exhibit every degree of variation between them.[1]
The domestication, as Charles Darwin remarks (The Variation of Animals and Plants under Domestication i. 287), is of very ancient date, with archaeological evidence for domesticated geese in Egypt more than 4,000 years ago.[2] They are much larger, and they have been selected for that larger size, with domesticated breeds weighing up to 10 kilograms (22 lb),[2] compared to the maximum of 3.5 kilograms (7.7 lb) for the wild swan goose and 4.1 kilograms (9.0 lb) for the wild greylag goose.[3] This affects their body structure; whereas wild geese have a horizontal posture and slim rear end, domesticated geese lay down large fat deposits toward the tail end, giving a fat rear and forcing the bird into a more upright posture. This also prevents flight for most domestic geese,[citation needed] though geese will run and flap their wings when startled, and may get a foot or so in the air momentarily.
They have also been strongly selected for fecundity, with females laying up to 50 eggs per year, compared to 5–12 eggs for a wild goose.[2][3]
Changes to the plumage are variable; many have been selected to lose dark brown tones of the wild bird. The result is an animal marked, or completely covered in white feathers. Others retain plumage close to the natural; some, such as the modern Toulouse goose look almost identical to the greylag in plumage, differing only in structure. White geese are often preferred as they look better plucked and dressed, with any small down feathers remaining being less conspicuous. From the time of the Romans, white geese have been held in great esteem.
Geese produce large edible eggs, weighing 120–170 grams (4.2–6.0 oz).[2] They can be used in cooking just like chicken's eggs, though they have proportionally more yolk, and this cooks to a slightly denser consistency. The taste is much the same as that of a chicken egg, but more gamey.
Because geese have a loud call and are sensitive to unusual movements, they can contribute towards the security of a property.[4] In late 1950s South Vietnam, the VNAF used flocks of geese to guard their parked aircraft at night due to the noise they would make at intruders.[5]
Geese in fiction and myth
When Aphrodite first came ashore she was welcomed by the Charites (Roman "Graces"), whose chariot was drawn by geese.
There are Mother Goose tales, such as a farmwife might have told; there is the proverbial goose that laid the golden eggs, warning about the perils of greed.
The geese in the temple of Juno on the Capitoline Hill were said by Livy to have saved Rome from the Gauls around 390 BC when they were disturbed in a night attack.[6] The story may be an attempt to explain the origin of the sacred flock of geese at Rome.
Liliane Bodson and Daniel Marcolungo, L'oie de bon aloi: Aspects de l'histoire ancienne de l'oie domestique [The goose in ancient life and folklore]. Vise (Musée Regional d'Archeologie et d'Histoire de Vise), 1994, discusses the image and lore of domestic geese in classical antiquity, with a separate chapter on the goose in folklore.
