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 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]
[36] [37] When looking at meat only, ruminants consume an average of 2.8 kg of human edible feed per kg of meat produced, while monogastrics need 3.2 kg. [36] [37] Finally, when accounting for the protein content of the feed, ruminant need an average of 0.6 kg of edible plant protein to produce 1 kg of animal protein while monogastric need 2 kg.
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.
A roasted Cornish game hen A Cornish game hen ready for the oven. Cornish game hen (also Rock Cornish game hen) is the USDA-approved name for a particular variety of broiler chicken, produced from a cross between the Cornish and White Plymouth Rock chicken breeds, that is served young and immature, weighing no more than two pounds (900 g) ready to cook.
Typical stocking densities in Europe range between about 22–42 kg/m 2 (5–9 lb/sq ft) or between about 11 to 25 birds per square metre (1.0 to 2.3/sq ft). [3] There is a reduction of feed intake and reduced growth rate when stocking density exceeds approximately 30 kg/m 2 (6 lb/sq ft) under deep litter conditions.
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.
Under a price control scheme in force between 5 February and 5 June, the Malaysian government imposed a ceiling price of RM8.90 per kg of chicken, in spite of the price control, local grocers are pricing chickens as high as RM17 per kg of chicken as the ceiling price was not economically sustainable.
