AB  - This study evaluated seasonal effects of micromineral concentrations in Brachiaria brizantha cv. Marandu pastures on small- and medium-sized farms in the micro regions of Castanhal and the area of Uruar?, State of Par?, Brazil. Forage was collected at the end of the dry (November, 1998) and the rainy seasons (June, 1999), to determine copper (Cu), zinc (Zn), iron (Fe), manganese (Mn) and cobalt (Co) concentrations. A complete randomized design was used, considering the main location as the major factor and the season as sub-plot. In the micro region of Castanhal, Brachiaria brizantha cv. Marandu pasture did not meet Zn requirements proposed by the NRC (1996) for lactating beef cattle. At both major locations, the studied pasture did not meet the Cu requirements, suggesting the need for supplementation of these minerals.
