Division 3 The lean meat content of a carcass shall be calculated according to the following formula:F1
United Kingdom
Ŷ = 68,39920953 – (0,39050694 × F) – (0,32611391 × V4F) + (0,07864716 × M) – (0,00762296 × V4M)
where:
Ŷ F V4F M V4M
the estimated percentage of lean meat in a carcass,
fat thickness as thinnest layer above muscle gluteus medius (in millimetres),
Average fat thickness of the complete bacon layer above the four lumbar vertebra (called VaF, VbF, VcF, VdF) (in millimetres),
Meat thickness from the cranial edge of muscle gluteus medius and the vertebrae canal (in millimetres),
Average meat thickness above the four lumbar vertebra (called VaM, VbM, VcM, VdM) (in millimetres).
This formula shall be valid for carcasses weighing between 60 and 120 kilograms (warm weight).
