Ŷ = 66,09149 – 0,82047 × X1 + 0,10762 × X2

where:

Ŷ

  • the estimated percentage of lean meat in a carcass,

    • X1

  • the thickness of backfat (including rind) in millimetres, measured 6 cm off the split line between the third and the fourth last ribs,

    • X2

  • the thickness of the dorsal muscle in millimetres, measured at the same time, in the same place and in the same way as X1.

    • This formula shall be valid for a carcass weighing between 60 and 130 kilograms.
