Division 3 The lean meat content of the carcasse shall be calculated according to the following formula:F1
United Kingdom
Ŷ = 68,52500 – 0,91029 × F HGP4 + 0,08512 × M HGP4
where:
Ŷ F HGP4 M HGP4
estimated percentage of lean meat in the carcasse
the thickness of back fat (including rind) in millimetres, measured at 7 cm off the midline of the carcasse between the third and fourth last rib
the thickness of muscle in millimetres measured at the same time and same place as F HGP4
This formula shall be valid for carcasses weighing between 50 and 120 kg.
