Division 2 The lean meat content of the carcasse shall be calculated according to the following formula:F1
United Kingdom
Ŷ = 60,81879 – 0,72992 × F DM + 0,12157 × M DM
where:
Ŷ F DM M DM
estimated percentage of lean meat in the carcasse
minimum thickness of visible (back) fat (including rind) on the midline of the split carcasse in millimetres, covering the lumbar muscle ( Musculus glutaeus medius )
visible thickness of the lumbar muscle on the midline of split carcasse in millimetres, measured as the shortest connection between the front (cranial) end of lumbar muscle and the upper (dorsal) edge of the vertebral canal
This formula shall be valid for carcasses weighing between 50 and 120 kg.
