It is more difficult to loose bad cutting habits later! 2 Beef carcase classification Carcase assessment addresses conformation and fat. Fat cover is scored on a 1-5 scale. Conformation is assessed from E to P. Combining scores for conformation and fat determines the markets which cattle suit. The Quality Standard Mark Scheme stipulates specific carcase classifications for beef. Fat Class 2-4H Conformation E-O+, the optimum classification for better meat yield. *Carcases within the following (See right)* parameters can carry the Quality Standard Mark. • Females under the age of 36 months are acceptable. They must not have increasing fatness Fat is determined by visual assessment of external fat Fat class cover. There are five main classes. Class 4 and 5 are been used for breeding or be in calf, subdivided into L (leaner) and H (fatter). they must not be pregnant. 1 2 3 4L 4H 5L 5H • Steers under the age of 36 months are acceptable. • Carcases must have a fat class of between 2–4H and have a conformation of E–O+. • For qualifying livestock 30 months or under: Maturation of 7 days is required on primals used for frying, roasting and grilling (from slaughter to the final consumer). r • For qualifying livestock aged E between 30–36 months: Maturation of 14 days is required on primals shoulde used for frying, roasting and and grilling (from slaughter to the final loin , consumer).
