Division 3 The lean meat content of carcasses shall be calculated according to the following formula:F1
United Kingdom
Ŷ = 52,61 – 0,6148 × F + 0,1842 × M
where:
Ŷ F M
the estimated percentage of lean meat in the carcass,
the minimum thickness of visible fat on the midline of the split carcass in millimetres, covering the M. gluteus medius (mm),
the visible thickness of the lumbar muscle on the midline of the split carcass, measured as the shortest connection between the front (cranial) end of the M. gluteus medius and the upper (dorsal) edge of the vertebral canal (mm).
This formula shall be valid for carcasses weighing between 60 and 120 kilograms.
