In 2018 the FCR of broilers is about 1.5, or 1.5 kg of feed to produce 1 kg of meat. [2] This compares very favorably with other sources of meat. It is estimated that broilers produce 6 kg of greenhouse gas per 1 kg of meat, as compared to 60 kg GHG /kg for beef cattle. [3] In the 1980s, it was typical to produce a 2 kilogram chicken in 70 days.
In 1950, the average American consumed 20 pounds (9 kg) of chicken per year, but 92.2 pounds (41.9 kg) in 2017. [108] Additionally, in 1980 most chickens were sold whole, but by 2000 almost 90 percent of chickens were sold after being butchered into parts.
Global meat production has increased rapidly over the past 50 years. According to Our World in Data, meat production has more than quintupled since 1961, reaching around 361 million tonnes in 2022. [1] The most popular meat globally is poultry, followed by pork, beef and mutton. Over 90 billion animals are slaughtered each year for 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]
More recent FAO figures (2009) have taken the earlier discrepancy into account, resulting in a significantly lower 95.2 kg (210 lb) for Denmark (13th in the world). [ 7 ] [ 8 ] When further adjusted for loss, calculations by DTU Fødevareinstituttet suggest the actual consumption was 48 kg (106 lb) per adult.
One-day-old chicks arriving to be unpacked and placed in shed Young birds being reared in a closed broiler house. Artificial selection has led to a great increase in the speed with which broilers develop and reach slaughter-weight. The time required to reach 1.5 kg (3 lb 5 oz) live-weight decreased from 120 days to 30 days between 1925 and 2005.
The capacity of the machine can be up to 26 tons of birds per hour (10.000 birds per hour – average weight 2.6 kg). Anglia Autoflow has developed a chicken harvester named the Easyload Harvester. [7] The company Bright Coop had made for few years the E-Z Catch Chicken Harvester, capable of handling 5000 birds per hour. [3]
Domesticated animals in the Philippines include pigs, chickens, water buffalo, goats, cats, and dogs. [1] [2] Domestication is when a species is selectively bred to produce certain traits that are seen as desirable. [3] Some desirable traits include quicker growth and maturity, increased fertility, adaptability to various conditions, and living ...
