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. Poultry – mostly chickens – are farmed in great numbers.
Chickens remained primarily to provide eggs, mostly to the farmer (subsistence agriculture), with commercialization still largely unexplored. Farm flocks tended to be small because the hens largely fed themselves through foraging, with some supplementation of grain, scraps, and waste products from other farm ventures. Such feedstuffs were in ...
There were 2786 regulated chicken producers, generating farm cash receipts of $1.6 billion in 2005. Compared to other livestock sectors (i.e. beef, dairy, and pork), the poultry and egg industry was the healthiest with regards to total income for the average operator. [1] In 2005, total chicken slaughters were 973.9 million kilograms.
Forced molting typically involves the removal of food and/or water from poultry for an extended period of time to reinvigorate egg-laying. Forced molting, sometimes known as induced molting, is the practice by some poultry industries of artificially provoking a flock to molt simultaneously, typically by withdrawing food for 7–14 days and sometimes also withdrawing water for an extended period.
Subsistence farming is being superseded by intensive animal farming in the more developed parts of the world, where, for example, beef cattle are kept in high-density feedlots, and thousands of chickens may be raised in broiler houses or batteries. On poorer soil, such as in uplands, animals are often kept more extensively and may be allowed to ...
The manure is usually stored in slurry form (slurry is a liquid mixture of urine and feces). During storage on the farm, slurry emits methane and when manure is spread on fields it emits nitrous oxide and causes nitrogen pollution of land and water. Poultry manure from factory farms emits high levels of nitrous oxide and ammonia. [108]
Poultry of the world (c. 1868) Poultry (/ ˈ p oʊ l t r i /) are domesticated birds kept by humans for the purpose of harvesting animal products such as meat, eggs or feathers. [1] The practice of raising poultry is known as poultry farming.
Mass production of chicken meat is a global industry and at that time, only two or three breeding companies supplied around 90% of the world's breeder-broilers. The total number of meat chickens produced in the world was nearly 47 billion in 2004; of these, approximately 19% were produced in the US, 15% in China, 13% in the EU25 and 11% in Brazil.
