Resumo: The large amount of agriculture area and the weather contribute with the based-pasture livestock production systems in Brazilian Amazon. Actually, the high demand for animal protein with quality increases productivity and profitability challenge´s. Focus on that, animal production research aim to identify and apply new technologies to improve livestock productivity. The objective with this study was to evaluate Nellore performance in pastures of Ipyporã brachiariagrass in Amazon biome. The experiment was carried out at Embrapa Agrossilvipastoril, from June/2016 to February/2017, and analyzed in two seasons: dry (June-October) and rainy (November/2016-February/2017). The experimental design was in randomized complete blocks with two treatments (hybrids: BRS RB331 Ipyporã and Mulato II) and four replications. The experimental area were divided into 8 paddocks with 1.5 ha each, totalizing 12 hectares. For performance evaluation, 24 not castrated Nellore steers (tracers), an average, with initial weights of 250 kg and 12 months of age were weighed every 28 days, after 16 h of fasting.
