Zusammenfassung:The present study aimed to obtain, through statistical methods, the independent variables that influence the economic and productive results of Brazilian beef cattle. Economic and productive information was collected from 106 farms in Brazil. Data collection was performed by the Instituto de Metricas Agropecuarias (Inttegra). The variable selection method used was stepwise regression followed by polynomial regression analyses. The variable beef cattle economic result showed the positive effect of disbursement per head per month and average weight gain. An average daily gain of 520 g in live weight was obtained, and this variable was influenced especially by nutrition cost. The arroba production (arroba is a unit of weight corresponding to 15kg) was influenced by the linear effect of nutrition cost and stocking rate. The variable arroba production in pasture showed a linear and positive effect of average weight gain in pasture and stocking rate in pasture. For profit per arroba, the variables nutrition cost, disbursement with pasture, and average sale price had a linear effect. The independent variables that had the greatest influence on the response variables were stocking rate, average daily weight gain, and nutrition cost. Thus, increases in investment in nutrition and stocking rate should result in higher production rates and improvements in the profitability of this activity. Key words: nutrition costing, average daily gain, profit, management, stocking rate. O presente trabalho teve como objetivo obter, por meio de metodos estatisticos, quais variaveis independentes influenciam as variaveis economicas e produtivas na bovinocultura de corte brasileira. O banco de dados utilizado foi obtido por coleta de informacoes economicas e produtivas em 106 fazendas no Brasil. O metodo de coleta de dados foi definido pelo Instituto de Metricas Agropecuarias (Inttegra). Foram realizadas andlises de selegao de variaveis pelo metodo Stepwise, seguido por andlises de regressao multipla. A variavel resultado economico da bovinocultura de corte teve efeito positivo do desembolso mensal por cabeqa e do ganho de peso medio diario. Para o ganho de peso medio didrio foi obtido um valor medio de 520 gramas, e esta varidvel foi influenciada principalmente pelo custeio com nutrigao. Para a produgao de arroba foi obtido efeito linear do custeio com nutrigao e da taxa de lotagao. Para a varidvel produgao de arroba a pasto foi obtido um efeito linear e positivo do ganho medio did
