McCartney, D., Ambrose, D. J., Colazo, M. G., Baron, V. S., Novak, S., Basarab, J. A.
This study examined the effects of residual feed intake (RFI), RFI adjusted for off-test backfat thickness (RFIfat) and RFI adjusted for off-test backfat thickness and feeding event frequency (RFIfat & activity) on heifer fertility and productivity. Beef heifers (n=190) were monitored for...
