Foram utilizados 84 animais com peso inicial de 205 kg e 8 meses de idade. Durante a seca os animais foram mantidos em pastagens de Brachiaria brizantha cv. Marandu, sob lotação contínua, submetidos a dois suplementos (proteico ou proteico e energético). No verão os animais foram submetidos a dois suplementos (mineral ou proteico). No outono os animais foram submetidos a três suplementos (mineral, proteico ou proteico e energético). No verão e outono foram utilizados módulos de pastagens de Panicum maximum cv. Tanzânia, sob lotação intermitente. Cada subgrupo, totalizando doze tratamentos, foi confinado com dieta única na terminação sendo abatidos com 500 kg. Na recria as características das forragens foram mantidas semelhantes, sendo as diferenças atribuídas ao tipo de suplementação. Durante a seca o suplemento proteico e energético resultou em maior ganho em peso (0,501 kg/dia) comparado com proteico (0,368 kg/dia). Animais que receberam suplemento proteico no verão apresentaram maior peso no inicio do outono (343 kg) comparado com suplemento mineral (326 kg). O peso inicial no confinamento foi influenciado pelas estratégias de suplementação na recria sendo maior nos animais que consumiram suplemento proteico e energético no outono (404 kg) seguidos por suplemento proteico (393 kg) e suplemento mineral (370 kg), o que refletiu no tempo de confinamento, sem alterar desempenho (0,910 kg/dia) e mantendo semelhantes as características de carcaça / The experiment was conducted at APTA, Colina - SP, to study the performance of Nellore bulls rearing stages on pasture and feedlot finishing. 84 Nellore cattle, with initial body weight of 205 kg and 8 months old were used. In dry season the animals were kept on Brachiaria brizantha cv. Marandu in continue stoking and submitted to two supplements (protein or protein and energy). In the second phase (summer) the animals were submitted to two supplements (mineral or protein). In the third phase (fall) the animals were submitted to three supplements (mineral, protein or protein and energy). In phases II and III modules pastures of Panicum maximum cv. Tanzania in discontinue stoking were used. Each subgroup, totalizing twelve treatments, was later confined to single diet for finishing with 500 kg. During the growing stages the characteristics of pasture, were kept similar, being the differences attributed to the type of supplementation. During the dry season the animals that consumed energy and protein supplement showed greater weight gain (0,501 kg/day) compared to protein (0,368 kg/day). The protein supplementation in the summer increased body weight (343 kg) compared to mineral (326 kg). The initial body weight in confinement was influenced by the rearing strategies, when animals fed with protein and energetic supplement in the fall season presented higher weight (404 kg) then the animals fed with protein supplement (393 kg) and mineral (370 kg). This caused difference in confinement time but not in the weight gain (0,910 kg/day) and carcass characteristics
