Ninety eight Nellore bulls (16 to 20 months old and 376 +- 29 kg BW) were evaluated in a feeding trial comprised of 21 days of adaptation to feedlot diet and place and a 70-day period of data collection. Total mixed ration was offered ad libitum and daily dry matter intake (DMI) was individually measured. Animals were weighted at the beginning, at the end and every 2 weeks during the experimental period. Feed efficiency was estimated by residual feed intake (RFI) which is the residual of the linear regression that estimates DMI based on average daily gain and mid-test metabolic body weight. Eighteen animals selected either as high feed efficiency (HFE) or low feed efficiency (LFE) groups were slaughtered, samples were collected and stored at -80C.
