significant ((F(2142) = 256.014, P b 0.05, R2 = 0.783, R2 Adjusted = 0.780) and the two independent observations, back fat thickness and muscle thickness, were statistically significant predictors of the lean meat percentage in the pig carcass (for back fat thickness: t = −16.165, P b 0.001 and for muscle thickness: t = 7.270, P b 0.001). The RMSEP was 2.51 ≈2.5 was accepted by the representatives of the EU PigMeat Committee. The prediction formula (Eq. (3)) for the FOM equipment resulting from the experiment was:
