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. In 2018 the FCR of broilers is about 1.5, or 1.5 kg of feed to produce 1 kg of meat. [2]
In the U.S., the average feed conversion ratio (FCR) of a broiler was 1.91 kilograms of feed per kilograms of liveweight in 2011, an improvement from 4.70 in 1925. [18] Canada has a typical FCR of 1.72. [19] New Zealand commercial broiler farms have recorded the world's best broiler chicken FCR at 1.38. [20]
In the first week of a broiler's life, it can grow up to 300 percent of its body size. A nine-week-old broiler averages over 9 pounds (4 kg) in body weight. At nine weeks, a hen will average around 7 pounds (3.2 kg) and a rooster will weigh around 12 pounds (5.5 kg), having a nine-pound (4 kg) average. Broilers are not raised in cages.
The farms produce 570 million tonnes of meat and 7.34 billion eggs annually. [3] Poultry feed is primarily made from imported soybean and soy meal. [ 4 ] The per capita consumption of meat and egg in Bangladesh remains below the level recommended by the Food and Agriculture Organization . [ 5 ]

In Indonesia and Malaysia, the term ayam kampung refer to indigenous chickens that are raised using traditional free range production techniques by almost ...
Actual manure generation will be lower because it is only a fractional component of litter. This translates to an average of about 0.7 ounce per day per bird, varying considerably over the life of the bird. This means that a single broiler house, which can contain well over 20,000 birds can generate over 40,000 lb (18,000 kg) of litter per flock.
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 ...
The most common commercial breed in the United Kingdom and the United States is the Pekin duck, which can lay 200 eggs a year and can reach a weight of 3.5 kg (7 lb 11 oz) in 44 days. [34] In the Western world , ducks are not as popular as chickens, because the latter produce larger quantities of white, lean meat and are easier to keep ...
