Broiler chicks. 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
Broilers are usually kept at high stocking densities. [14] This can reduce feed intake and growth. [2] Management conditions (litter quality, temperature and humidity) are however more important than stocking density. [23] Many broilers die during the processes of catching, packing and transport.

The regular feed conversion ratio, i.e. output fish mass divided by total feed mass. The conversion ratio only taking into account the fish-based component of fish feed, called the FIFO ratio (or Fish In – Fish Out ratio). FIFO is fish in (the mass of harvested fish used to feed farmed fish) divided by fish out (mass of the resulting farmed ...
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.
Parsons et al. (2006), evaluating different corn particle sizes in the broiler feed found that the largest particle size (2.242 mm) gave better feed intake than the other particle sizes tested (0.781, 0.950, 1.042 and 1.109 mm). Nir et al. (1994), however, argued that the development of broilers was influenced by changing particle sizes ...
Two kinds of poultry were generally offered: broilers or "spring chickens", young male chickens, a byproduct of the egg industry, which were sold when still young and tender (generally under 3 pounds live weight); and "fowls" or "stewing hens", also a byproduct of the egg industry, which were old hens past their prime for laying.

Diseases can be avoided with proper maintenance of the feed and feeder. A feeder is the device that supplies the feed to the poultry. [8] For privately raised chickens, or chickens as pets, feed can be delivered through jar, trough or tube feeders. The use of poultry feed can also be supplemented with food found through foraging. [9]
Small farmers are often absorbed into factory farm operations, acting as contract growers for the industrial facilities. In the case of poultry contract growers, farmers are required to make costly investments in construction of sheds to house the birds, buy required feed and drugs – often settling for slim profit margins, or even losses.
