To avoid deforestation in the Amazon rainforest is necessary to increase productivity and profitability in beef cattle. So the aim of this study was to evaluate economic efficiency and productivity of 5 intensive pasture systems (IPS) on beef cattle production in Mato Grosso, Amazon biome, January 2013 to December 2014, part of the Livestock Low Carbon Integrated Project-ICV. Production and economic data were collected using control software (Prodap Professional GP) and analyzed by electronic spreadsheets (Microsoft Excel). The total of IPS was 177.7 ha (ha) and 1,877 cattle. The average of pasture was 35.5 ha/farm and 125 animals/IPS. The IPS was established with Panicum maximum ‘Mombaça’, with limestone, potassium chloride, triple phosphate and urea as soil analysis. During the rainy season were placed urea according stocking rate. The systems was developed exclusively on a grazing system with a base herd comprised of Zebu (Nelore) and crossbred Bos taurus × Bos indicus cattle. The zootechnical and economic indexes were compared in 3 periods, April–September 2013, October–2013 to March 2014, April–September 2013, by Duncan test, besides Person correlations, with significance level of 5%. During rainy season, October–2013 to March 2014, stocking rates (5.15 animals/ha), live weight/ha (1,553 kg), body weight produced (404 kg/ha) and total operating costs (US$ 248.18/ha) were higher than other periods (P < 0.05). There was no statistical difference to net margin of 155.49 US$/ha (P > 0.05). High correlations were found (0.76) between body weight produced (kg/ha) and total operating costs (US$/ha) (P < 0.05). High correlations were found (0.898) between body weight produced (kg/ha) and net margin (US$/ha) (P < 0.05) indicating that higher productivity is related to higher net margin, despite the higher cost per area. The period had influence on production of beef cattle and on costs in intensive pasture system, but the net margin indicated that the activity of beef cattle in Amazon biome can be profitable and had high correlation with animal production.
