Popis:	Performance and carcass characteristics of bulls or steers supplemented or not supplemented during the winter. Forty Nellore bovines were used. Animals were divided in two groups: 1) SUP - Animals on pasture and supplemented (0.5% of live body weight) with a concentrated during the winter (dry season), and 2) NSU - Animals on pasture, without supplementation. Half of the animals of each treatment was steers and the other half was bulls. Best average daily gain (ADG) during the period of the winter was observed in the supplemented animals (SUP = 0.339; NSU = 0.193 kg), and the animals belonging to the control group (NSU) presented compensatory weight gain in the period of the summer. Bulls had greater ADG during the whole period than steers (0.506 vs. 0.412 kg), and they reached the slaughter weight (480 kg) at a younger age (330 vs. 409 days up to slanghter). Best cold carcass dressing percentage was verified for steers and the supplementation did not promote better carcass characteristics in the tested animals.
