The human population is projected to grow to 9 billion by 2050, and meat production is expected to increase by 40%. [12] Global production and consumption of poultry meat have been growing recently at more than 5% annually. [11] Meat consumption typically increases as people and countries get richer. [13] Trends also vary among livestock sectors.
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. More than 60 billion chickens are killed for consumption annually.
The broiler industry is the process by which broiler chickens are reared and prepared for meat consumption. Worldwide, in 2005 production was 71,851,000 tonnes. From 1985 to 2005, the broiler industry grew by 158%. [1] A key measure of performance is the feed conversion ratio (FCR), the ability to convert feed into edible product.
After a few false starts, such as the Maine Experiment Station's failure at improving egg production, [13] success was shown by Professor James Dryden at the Oregon Experiment Station. [14] The culling and slaughter of non-egg laying chickens created a source of poultry meat. However, poultry meat supply continued to lag demand, and poultry was ...
Today, eggs are produced on large egg ranches on which environmental parameters are well controlled. Chickens are exposed to artificial light cycles to stimulate egg production year-round. In addition, forced molting is commonly practiced in the US, in which manipulation of light and food access triggers molting, in order to increase egg size ...
Poultry is the second most widely eaten type of meat in the world, accounting for about 30% of total meat production worldwide compared to pork at 38%. Sixteen billion birds are raised annually for consumption, more than half of these in industrialised, factory-like production units. [ 58 ]
A free range pastured chicken system. Pastured poultry also known as pasture-raised poultry or pasture raised eggs is a sustainable agriculture technique that calls for the raising of laying chickens, meat chickens (broilers), guinea fowl, and/or turkeys on pasture, as opposed to indoor confinement like in battery cage hens or in some cage-free and 'free range' setups with limited "access ...
Male birds of the laying strains do not lay eggs and are unsuitable for meat production, therefore, they are culled soon after being sexed, often on the day of hatching. [45] Methods of culling include cervical dislocation , asphyxiation by carbon dioxide and maceration using a high speed grinder.
