A simulation model for predicting the voluntary feed intake (VFI) of a growing pig is presented. Five parameters were used
to describe the effects of pig genotype and sex based on the ratio of lipid mass to protein mass at maturity and the scaling of
lipid mass to protein mass during potential growth (b). The simulation aimed to predict VFI, performance and body
composition based on the inherent potential protein growth rate according to pig genotype and sex. All aspects of pig
performance and body composition were affected to different degrees by both genotype and sex. In a simulation including
both the growing stage and the finishing stage, type Lb1 (entire male with improved genotype) grew faster, had a lower feed
conversion ratio, took less time reach to 120 kg and had a higher total protein mass and lower total lipid mass than the other
types investigated.
