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.
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]
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.
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 650 ...
A carcass grade is an assessment of quality for a culled cow or bull. The various grades are defined by the United States Department of Agriculture, and assessments are based primarily on the fatness of the cow to be culled. [1] Cows are culled from herds for a variety of reasons, including poor production, age, or health problems. [2]
A steer that weighs 1,000 lb (450 kg) when alive makes a carcass weighing approximately 615 lb (280 kg) once the blood, head, feet, skin, offal and guts are removed. The carcass is then hung in a cold room for between one and four weeks, during which time it loses some weight as water dries from the meat.
Likewise for the fat class, where 1 is Low, 2 is Slight, 3 is Average, 4 is High, and 5 is Very High. A typical classification would be R4L where the R refers to a "Good” carcass with an “Average” to “High” covering of fat according to the MLC. The grader is usually an independent classifier who also monitors carcass dressing ...
Modern commercial broilers are bred to reach a slaughter-weight of about 2 kg (4.4 lb) in only 5 to 7 weeks. [6] [13] [14] As a consequence, the behaviour and physiology of broilers reared for meat are those of immature birds, rather than adults. Slow growing free-range and organic strains have been developed which reach slaughter-weight at 12 ...
