Original text. Later amendments are not shown.

LMP = 66,86 – 0,6549 * Fat + 0,0207 * Muscle

where:

LMP
  • the estimated percentage of lean meat in the carcass,

  • Fat
  • the CGM 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,

  • Muscle
  • the CGM 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.
