Post-weaning feed
efficiencyResidual feed intake (RFI)
RFI quantifies variation in feed intake that is unrelated to BWand ADG in growing cattle
RFI equals actual dry matter (DM) intake minus expected DMI based on mid-test BW0.75 and ADG
Efficient animals consume less feed than expected for a given BW and growth rate
RFI is moderately heritable
RFI is positively correlated with DM intake (0.60 to 0.70) but is not with postweaning daily gain or body weight
