Division 3 The lean meat content of the carcass shall be calculated according to the following formula:F1
United Kingdom
Ŷ = 59,42 + 0,1322 × M 2 – 0,6275 × F 2
where:
Ŷ M 2 F 2
the estimated percentage of lean meat in the carcass,
the thickness of the dorsal muscle in millimetres, measured at the third to fourth last rib position, 6 centimetres from the dorsal midline, measured parallel to the split line of the carcass,
the thickness of back-fat (including rind) in millimetres measured at the same time, in the same place and in the same way as M2.
This formula shall be valid for carcasses weighing between 60 and 120 kilograms.
