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 hens used in egg production in the US, as of 2011 the FCR was about 2, with each hen laying about 330 eggs per year. [25]
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.
Feedlots producing live cattle for slaughter will typically purchase 500–850 pounds (230–390 kg) feeder cattle calves and feed to grow the animals into 850–1,400 pounds (390–640 kg) cattle. [ 3 ] [ 2 ] Backgrounding operations will typically purchase 300–600 pounds (140–270 kg) feeder cattle calves and feed to grow the animals into ...
Yield grades are intended to estimate the pounds of boneless closely trimmed retail cuts from the carcass. Closely trimmed refers to approximately ¼ inch of external fat. Yield grade is determined by considering four carcass characteristics: external fat; kidney, pelvic and heart fat (KPH); ribeye area (REA); and hot carcass weight (HCW).
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]
mass flow meter: mass flow rate of a fluid travelling through a tube mass spectrometer: masses of ions, used to identify chemical substances through their mass spectra measuring cup: liquid and dry goods measuring cylinder: volume measuring spoon: a spoon used to measure an amount of an ingredient, either liquid or dry megger: electrical insulation
Linear estimation based on body mass or weight. This simple method is sometimes used for cattle. The number of animal units represented by one or more head of cattle may be calculated by dividing their total body mass in kg by 454 (or dividing their weight in pounds by 1000). Thus an 800-pound steer would be considered equivalent to 0.8 animal ...
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 ...
