Description:	The residual gain (RG) was proposed as a measure that estimates the weight gain according to feed intake and body weight (Koch et al., 1963; J. Anim. Sci., 22:486). With the objective to verify the differences between RG classes in performance, feed efficiency and ultrasound carcass traits in Nellore cattle (bulls n = 141, 21-mo old 385 kg initial BW; steers n = 224, 20-mo old, 350 kg initial BW), we computed the average daily gain (ADG), dry matter intake (DMI), feed conversion ratio (F:G), residual feed intake (RFI) and the gain of ribeye area (GREA), gain of backfat thickness (GBFT) and gain of rumpfat thickness (GRFT) measured by ultrasound.
