As of 2011 in the US, broiler chickens has an FCR of 1.6 based on body weight gain, and mature in 39 days. [25] At around the same time the FCR based on weight gain for broilers in Brazil was 1.8. [25] The global average in 2013 is around 2.0 for weight gain (live weight) and 2.8 for slaughtered meat (carcass weight). [26]
For example, the dress weight for chickens and other fowl is closer to 75% of the live weight, [3] which is significantly higher than that of cattle, which can be from 50-70% depending on breed and methods used. [2] To compare, a 250-pound pig will typically have a dressed weight of 180 pounds and a retail cuts weight of 144 pounds.
A carcass grade (or expected carcass grade) is used to determine selling prices for cull cows, which are estimated to comprise 20% of the beef available to consumers in the United States. [1] A Body Condition Scoring system or BCS, which is used to grade live cows and bulls, is used to determine the carcass grade. [1]
Backgrounding cattle that achieve weights of 650–700 pounds (290–320 kg) are suitable for sale to grass feeding operations, whereas those achieving weights of 800–825 pounds (363–374 kg) are suitable for sale to feedlot operators. [4] Buyers of feeder cattle tend to look for high average gain (in weight) and low feed-to-gain ratio.
The EU employs a grading scheme that emphasizes carcass shape and amount of fat covering [4] instead of marbling and aging. The differences in grading yield incompatible value judgments of beef value in the United States and the EU. [5] Most beef offered for sale in supermarkets in the United States is graded U.S. Choice or Select. U.S. Prime ...
The imperial system has a hundredweight, defined as eight stone of 14 lb each, or 112 lb (50.802 345 44 kg), whereas a US hundredweight is 100 lb (45.359 237 kg). In both systems, 20 hundredweights make a ton. In the US, the terms long ton (2240 lb, 1 016.046 9088 kg) and short ton (2000 lb; 907.184 74 kg) are used.
A Großvieheinheit (GV or GVE) is a conversion key used to compare different farm animals on the basis of their live weight. A Großvieheinheit represents 500 kilogrammes (roughly the weight of an adult bull). In the wild it excludes small animals like amphibians and insects, but is used for game in forestry and hunting.
Live weight gains that allow lambs to reach about 36 kg (79 lb) (17 kg (37 lb) - 18 kg (39 lb) carcase) in 100 days has been obtained from first cross animals grown in the Mallee region. Local experience indicates that carcasses with fat scores [ 3 ] of 2 to 3 are easily obtained under these conditions.
