Division 3 The lean meat content of carcasses shall be calculated according to the following formula:F1
United Kingdom
Ŷ = 69,38252 – 0,79120 × BF + 0,00994 × LD
where:
Ŷ BF LD
the estimated percentage of lean meat in the carcass,
the thickness of back-fat (including rind) in millimetres, measured at 7 cm off the midline of the split carcass, between the second and third last ribs,
the thickness of the dorsal muscle in millimetres, measured at the same time and in the same place as BF.
This formula shall be valid for carcasses weighing between 50 and 120 kg.
