Division 3 The lean meat content of the carcass shall be calculated according to the following formula:F1
United Kingdom
Ŷ = 54,48 + 0,1272 × M 1 – 0,3090 × F 1 + 0,0828 × M 2 – 0,2802 × F 2
where:
the estimated percentage of lean meat in the carcass,
the thickness of the dorsal muscle in millimetres, measured at the last rib position, 7 centimetres from the dorsal midline perpendicularly to the muscle,
the thickness of the dorsal muscle in millimetres, measured at the third to fourth rib from the last rib position, 7 centimetres from the dorsal midline perpendicularly to the muscle,
the thickness of back-fat (including rind) in millimetres measured at the same time, in the same place and in the same way as M 1 ,
the thickness of back-fat (including rind) in millimetres measured at the same time, in the same place and in the same way as M 2 ,
This formula shall be valid for carcasses weighing between 60 and 120 kilograms.
