The lean meat content of the carcase should be calculated according to the following formula:
-
ŷ = 65,1 — 1,158x1 + 0,176x2
where:
ŷ -
the estimated percentage of lean meat in the carcase,
x1 -
the thickness of back-fat (including rind) in millimetres, measured at 6 cm off the dorsal midline of the carcase, between the third and fourth last ribs,
x2 -
the thickness of muscle in millimetres, measured at the same time and in the same place as x1.
-
The formula shall be valid for carcases weighing between 30 and 120 kilograms.
