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.
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 ...
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]
In addition, a newborn double-muscled calf's birth weight is significantly greater than that of a normal calf. [ 6 ] Belgian Blue cattle have improved feed conversion ratio (FCR) due to lower feed intake compared to weight gain [ 6 ] due to an altered composition of body weight gain which includes increased protein and decreased fat deposition ...
Saleable meat yield was an average 34.9% of live weight for the three British cattle breeds, compared with 40.4% for the five other continental European breeds, and 46.0% for Limousins, for two market end points of 225 kg saleable meat at 8mm fat trim, and 210 kg saleable meat at 0mm fat trim. Live weight gain for the Limousins averaged 1.27 kg ...
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.
