Tibial dyschondroplasia

Last updated

Tibial dyschondroplasia (TD) is a metabolic disease of young poultry that affects the growth of bone and cartilage. Often occurs in broilers (chickens raised for meat) and other poultry which have been bred for fast growth rates. The tibial cartilage does not mature enough to ossify (turn into bone).[ citation needed ] This leaves the growth plate prone to fracture, infection, and deformed bone development. It is the leading cause of lameness, mortality, and carcass condemnations in commercial poultry. [1]

Poultry Domesticated birds kept by humans for their eggs, meat, or feathers

Poultry are domesticated birds kept by humans for their eggs, their meat or their feathers. These birds are most typically members of the superorder Galloanserae (fowl), especially the order Galliformes.

Pastured poultry

Pastured poultry is a sustainable agriculture technique that calls for the raising of laying chickens, meat chickens (broilers), and/or turkeys on pasture, as opposed to indoor confinement. Humane treatment and the perceived health benefits of pastured poultry are causing an increase in demand for such products.

Broiler

A broiler is any chicken that is bred and raised specifically for meat production. Most commercial broilers reach slaughter weight between four and seven weeks of age, although slower growing breeds reach slaughter weight at approximately 14 weeks of age. Typical broilers have white feathers and yellowish skin. Broiler or sometimes broiler-fryer is also used sometimes to refer specifically to younger chickens under 4.5 pounds, as compared with the larger roasters.

Cornish game hen

Cornish game hen is the USDA-approved name for variety of broiler chicken, produced from a cross between the Cornish and White Plymouth Rock chicken breeds, that is served young and immature, weighing no more than two pounds (900 g) ready to cook.

Osteochondrosis is a family of orthopedic diseases of the joint that occur in children, adolescents and other rapidly growing animals, particularly pigs, horses, dogs, and broiler chickens. They are characterized by interruption of the blood supply of a bone, in particular to the epiphysis, followed by localized bony necrosis, and later, regrowth of the bone. This disorder is defined as a focal disturbance of endochondral ossification and is regarded as having a multifactorial cause, so no one thing accounts for all aspects of this disease.

Hock burns are marks found on the upper joints of chickens and other birds raised on broiler farms. These marks are where the ammonia from the waste of other birds has burned through the skin of the leg, leaving a mark. Many meat processors now remove these marks as they discourage customers. Hock burn normally does not surpass 15% of a flock, according to poultry industry standards, but independent studies have found incidents of hock burn more common. Researchers in Britain found that hock burn could be identified in 82% of chickens sold in supermarkets.

Chicken as food Type of meat

Chicken is the most common type of poultry in the world. Owing to the relative ease and low cost of raising them in comparison to animals such as cattle or hogs, chickens have become prevalent throughout the cuisine of cultures around the world, and their meat has been variously adapted to regional tastes.

Poultry litter

In agriculture, poultry litter or broiler litter is a mixture of poultry excreta, spilled feed, feathers, and material used as bedding in poultry operations. This term is also used to refer to unused bedding materials. Poultry litter is used in confinement buildings used for raising broilers, turkeys and other birds. Common bedding materials include wood shavings, sawdust, peanut hulls, shredded sugar cane, straw, and other dry, absorbent, low-cost organic materials. Sand is also occasionally used as bedding. The bedding materials help absorb moisture, limiting the production of ammonia and harmful pathogens. The materials used for bedding can also have a significant impact on carcass quality and bird performance.

New Hampshire chicken breed of chicken

The New Hampshire breed of chicken originated in the state of New Hampshire in the United States. Poultry farmers, starting with Rhode Island Reds and performing generation after generation of selective breeding, intensified the characteristics of early maturity, rapid full feathering, and production of large brown eggs. The mature birds are a rich chestnut red, of a somewhat lighter and more even shade than the Rhode Island Reds. The chicks are also a lighter red.

Poultry farming Part of animal husbandry

Poultry farming is the form of animal husbandry which raises domesticated birds such as chickens, ducks, turkeys and geese to produce meat or eggs for food. It has originated from the agricultural era. Poultry – mostly chickens – are farmed in great numbers. More than 60 billion chickens are killed for consumption annually. Chickens raised for eggs are known as layers, while chickens raised for meat are called broilers.

Naked Neck

The Naked Neck is a breed of chicken that is naturally devoid of feathers on its neck and vent. The breed is also called the Transylvanian Naked Neck, as well as the Turken. Originally from Transylvania - Romania, and was largely developed in Germany. The name "Turken" arose from the mistaken idea that the bird was a hybrid of a chicken and the domestic turkey. Naked Necks are fairly common in Europe today, but are rare in North America and very common in South America. The trait for a naked neck is a dominant one controlled by one gene and is fairly easy to introduce into other breeds, however these are hybrids rather than true Naked Necks, which is a breed recognized by the American Poultry Association since 1965, it was introduced in Britain in the 1920s. There are other breeds of naked necked chicken, such as the French naked neck, which is often confused with the Transylvanian, and the naked necked gamefowl.
