Division 3 The lean meat content of the carcase should be calculated according to the following formula:
United Kingdom
= 64,19701 – 0,39379X2 + 0,08082X3 – 0,33910X4
Where:
the estimated percentage of lean meat in the carcase,
the thickness of back-fat (including rind) in millimetres, measured at 7 cm off the midline of the carcase, at the last rib,
the thickness of muscle in millimetres, measured at the same time and in the same place as X2,
the thickness of back-fat (including rind) in millimetres, measured at 7 cm off the midline of the carcase, between the third and the fourth last rib.
The formula shall be valid for carcases weighing between 60 and 120 kilograms.
