Division 3 The lean-meat content of the carcass shall be calculated according to the following formula:
United Kingdom
LMP = 65,92 – 0,6337 * Fat + 0,0446 * Muscle
where:
LMP Fat Muscle
the estimated percentage of lean meat in the carcass,
the HGP7 fat depth measurement (including rind) in millimetres, as measured at the third to fourth rib from last rib position, 6 centimetres from the dorsal midline,
the HGP7 muscle depth measurement (including rind) in millimetres, as measured at the same time and in the same place as Fat.
This formula shall be valid for carcasses weighing between 73,5 and 107,5 kilograms.
