This trial was conducted at National Beef Cattle Research Center of Brazilian Agricultural Research Corporation (Embrapa Beef Cattle). Forty five F1 Aberdeen Angus-Nellore steers were used to evaluate the effects of different dry seasons feeding schemes on carcass characteristics. The treatments were: control, without supplementation (S/S); supplementation in 2nd dry period (S2S); supplementation in 1st dry period (S1S); supplementation in 1st and 2nd dry periods (S12S) and supplementation in 1st dry period and confinament in 2nd one (S1C2). Animals were slaughtered at 460-480 kg of live weight and the treatments effects were evaluated by least square means. Steers with higher nutritional levels in 2nd dry season (S1C2; S2S; S12S) showed more dressing percentage and higher hot and cold carcass weights than those supplemented only in 1st dry period or non supplemented. Animals supplemented only in 1st dry season showed similar carcasses than non supplemented. It was concluded that increasing the 2nd dry season nutritional level is primary to expand the dressing percentage. Supplementation in 1st dry period solitarily does not affect dressing percentage neither carcass quality.
