The objective of this study is to evaluate the effects of production, environmental and economic aspects of rearing beef steers supplemented in Brachiaria brizantha (Hochst ex A. Rich) Stapf cv. Marandu during the wet and wet-dry transition season and finishing strategies in the dry season. Trial will be conducted in three phases: wet season (2013/2014), transition period wet/dry season and dry season of 2014. In the rainy season, from December/2013 to March/2014 will be evaluated three canopy height, 15, 25 and 35 cm in a continuous stocking rate management associate to different supplementation strategies: multiple supplements in the amount of 0.3% and 0.6% of body weight (BW ) in animals kept in pastures of 15 cm, 0.1% and 0.3% of the BW in the animals kept in pastures 25 cm, and 0.1% of the BW or mineral mixture in the animals maintained in the pastures of 35cm. Experiment will be conducted in a completely randomized design with six treatments and three replications (paddocks) with repeated measures on the time (three periods of 28 days). In the transition wet-dry season from March to June/2014 the animals from the pasture grazed at 15 com heights will be finished in a feedlot and rated the growing phase history. In the transition season, the animals maintained in the pasture of the 25 cm height will receive 0.3% and 0.6% BW of supplement, and the animals of the 35 cm height will receive 0.1% and 0.3% BW of supplements. In this phase data will be analyzed according to a completely randomized design with four treatments and three replications (paddocks) with repeated measures on time (three periods of 28 days). In the dry season, from June to September 2014 a half of the animals maintained in pasture during the transition phase will be finish on pasture receiving 1.0% BW of supplement, and the other half will finish in feedlot to evaluate the effects of the historical of strategies adopted during the wet, and wet/dry season.
