Division 3 The lean meat content of carcasses shall be calculated on the basis of 10 variables according to the following formula:F1

Ŷ = 73,8876 + (AF3_R2P1 × – 1,036616) + (AF3_R2P3 × – 0,180173) + (AF3_R2P13 × – 0,144679) + (AF3_R2P15 × – 0,221519) + (AF3_R3P5 × 0,136061) + (AF3_R4P4 × 0,249888) + (AF3_R4P5 × 0,330109) + (AF3_R4P6 × 0,184696) + (AF3_R4P8 × – 0,112875) + (AF3_R4P9 × – 0,113663)

where:

• Ŷ = the estimated percentage of lean meat in the carcass,

• R2P1, R2P3, R2P13 … R4P9 — are the variables measured by Autofom III.
