# Commission Decision of 14 July 1989 authorizing methods for grading pig carcases in Germany (Only the German text is authentic) (89/471/EEC), Division 3: The lean meat content of carcasses shall be calculated on the basis of 5 variables according to the following formula:

Extent: E+W+S+N.I.

LMP = 65,21715434 – 0,23517230•R2P2 – 0,23350031•R2P6 – 0,25098775•R2P10 – 0,10926670•R2P13 + 0,19342930•R3P5
where:
LMP = the estimated percentage of lean meat in the carcass,
R2P2 — weighted average of two fat measures without skin (mm), weighted 2/3 and 1/3, respectively,
R2P6 — weighted average of two minimum fat measures (mm), weighted 2/3 and 1/3, respectively,
R2P10 — minimum fat of the cross-section (mm),
R2P13 — the initial assessment of the carcass size,
R3P5 — the maximum meat measure (maximum rib position minus minimum fat position converted to mm).
