$\text{MW}$ = mean metabolic weight; $\text{WG}$ = weight gain; $\text{FG}$ = backfat thickness gain; $\text{RFI}$ = residual feed intake (Model 8); $\text{FI}$ = feed intake; ${\widehat{\mathbf{I}}}_{\text{FI}}$ = selection against feed intake; ${\widehat{\mathbf{I}}}_{\text{tRFI}}$ = selection for reduced traditional $\text{RFI}$; ${\widehat{\mathbf{I}}}_{\text{RFI}}$ = selection against the consumption of feed beyond individual needs defined by index of overall needs (Model 8); ${\widehat{\mathbf{I}}}_{\text{FI}/\text{MW}}$, ${\widehat{\mathbf{I}}}_{\text{FI}/\text{WG}}$, ${\widehat{\mathbf{I}}}_{\text{FI}/\text{FG}}$ = selection to reduce the amount of feed consumed for maintenance, growth and fat deposition, respectively
