The Ayam Cemani is a rare breed of chicken from Indonesia. They have a dominant gene that causes hyperpigmentation (fibromelanosis), making the chicken mostly black, including feathers, beak, and internal organs. The Cemani is a very popular gamecock for cockfighting in Bali because their thighs have much more muscle compared to other chickens, which leads to them being much faster. [1]

Etymology

Ayam means "chicken" in Indonesian, while cemani (originally a Javanese word) means "thoroughly black" (down to the bones). [2]

Origin

As a pure Indonesian breed, the breed originated from the island of Java, Indonesia, and has probably been used since the 12th century for religious and mystical purposes. [3]

The breed was described by Dutch colonial settlers [4] and first imported to Europe in 1998 by Dutch breeder Jan Steverink.[ citation needed ] Currently, this breed of chicken is kept in the Netherlands, Belgium, Germany, Slovakia, Sweden, Italy, America and the Czech Republic. Ayam Cemani may have also been brought to Europe by Dutch seamen.

Description

The optimal standard is that their beaks, tongues, combs and wattles appear black, and even their meat and organs are black or gray. However, contrary to popular belief, their bones are not actually black. Their blood is normally colored. They are a medium sized chicken that are known for their beautiful and unique look. They are usually a somewhat friendly bird but they are still relatively skittish. The birds' black color occurs as a result of excess pigmentation of the tissues, caused by a genetic condition known as fibromelanosis. [5] Fibromelanosis is also found in some other black or blue-skinned chicken breeds, such as the Silkie. [6] [7] The roosters weigh 2–2.5 kg (4.4–5.5 lb) and the hens 1.5–2 kg (3.3–4.4 lb). The hens lay tinted or cream-colored eggs, although they are poor setters and rarely hatch their own brood. Eggs weigh an average of 45 g (1.6 oz).

Poultry are domesticated birds kept by humans for the purpose of harvesting animal products such as meat, eggs or feathers. The practice of raising poultry is known as poultry farming. These birds are most typically members of the superorder Galloanserae (fowl), especially the order Galliformes. The term also includes waterfowls of the family Anatidae but does not include wild birds hunted for food known as game or quarry.

Beak trimming, or beak conditioning, is the partial removal of the beak of poultry, especially layer hens and turkeys, although it is also be performed on some quail and ducks. When multiple birds are confined in small spaces due to farming practices, they are more likely to hurt each other through pecking. Beak trimming aims to avoid damage done by pecking, although the practice is criticized by animal welfare organizations and banned in several European countries. Beak trimming is most common in egg-laying strains of chickens. In some countries, such as the United States, turkeys routinely have their beaks trimmed. In the UK, only 10% of turkeys are beak trimmed.

However, all of the main domestic turkey varieties today descend from the turkey raised in central Mexico that was subsequently imported into Europe by the Spanish in the 16th century.

<span class="mw-page-title-main">Silkie</span> Chinese chicken breed

The Silkie is a Chinese breed of chicken named for its atypically fluffy plumage, which is said to feel like silk and satin. The breed has several other unusual qualities, such as black skin and bones, blue earlobes, and five toes on each foot, whereas most chickens have only four. They are often exhibited in poultry shows, and also appear in various colors. In addition to their distinctive physical characteristics, Silkies are well known for their calm and friendly temperament. It is among the most docile of poultry. Hens are also exceptionally broody, and care for young well. Although they are fair layers themselves, laying only about three eggs a week, they are commonly used to hatch eggs from other breeds and bird species due to their broody nature. Silkie chickens have been bred to have a wide variety of colors which include but are not limited to: Black, Blue, Buff, Partridge, Splash, White, Lavender, Paint and Porcelain.
