Division 3 The lean meat content of carcasses shall be calculated according to the following formula:F1
United Kingdom
Ŷ = 66,49 – 0,891 G + 0,104 M
where
Ŷ G M
the estimated percentage of lean meat in the carcass,
the thickness of the fat (including rind) between the second and third last ribs, at 7 cm off the dorsal midline, at a trajectory perpendicular to the rind (in millimetres),
the thickness of the muscle between the second and third last ribs, at 7 cm off the dorsal midline, at a trajectory perpendicular to the rind (in millimetres).
The formula shall be valid for carcasses weighing between 45 and 125 kg.
