The aim of this study was to analyze production indices: birth rate, calving interval, service period and milk production, as well as, indicators of economic efficiency: crude margin, net margin and result (profit or loss) and the composition of production costs of 20 dairy farms in the Norte Fluminense. Were determined the components of the production costs: operating cost, effective operational cost and total cost. The dairy farms obtained the following averages for production indices: birth rate of 57.4 ? 12.18% with a coefficient of variation of 21.22%, calving interval of 13.5 ? 0.68 months with a coefficient of variation 5.05%, period of 116.2 ? 9.23 days service with a coefficient of variation of 7.95% and milk production of 6.1 ? 2.58 liters per day with a coefficient of variation of 41.96 %. Average crude margin of R$ 32,514.51 ? R$ 20,905.58 with a coefficient of variation of 64.30% and an average net margin of R$ 29,239.05? R$ 20,840.88 with a coefficient of variation of 71.28% was found, and producers remain in business in the short term is possible pay the actual operating cost. And result (loss), on average - R$ 124,050.95 ? R$ 27,757.68 with a coefficient of variation of 22.38%. By presenting injury, revenues does not remunerate investment, ie, the financial fixed assets in equity as land, improvements and so on. The low production indicex regarding the birth rate and milk production must be improved to obtain higher revenues in the activity and better milk production. The highest percentage of participation in the composition of revenue and the costs of investment was the asset value when recorded, and the sale of milk and the purchase of animals, respectively, when not accounted for this item. Regarding expenses with funding, the highest percentages were related to labor, grazing, concentrated feed and roughage supplementation. Producers remain analyzed short-term activity, but for improvement in production should be production indices with greater use of technical assistance for the return on economic efficiency. / A explora??o da bovinocultura de leite no Brasil constitui importante atividade no processo de desenvolvimento econ?mico e social do Pa?s. O objetivo do presente trabalho foi analisar os ?ndices zoot?cnicos: taxa de natalidade, intervalo de partos, per?odo de servi?o e produ??o de leite, bem como, os indicadores de efici?ncia econ?mica: margem bruta, margem l?quida e resultado (lucro ou preju?zo) e a composi??o dos custos de produ??o de 20 propriedades leiteiras na regi?o Norte Fluminense. Foram determinados os componentes do custo de produ??o: custo operacional, custo operacional efetivo e custo total. As propriedades leiteiras obtiveram as seguintes m?dias para os ?ndices zoot?cnicos: taxa de natalidade de 57,4 ? 2,18% com coeficiente de varia??o de 21,22%, intervalo de partos de 13,5 ? 0,68 meses com coeficiente de varia??o de 5,05%, per?odo de servi?o de 116,2 ? 9,23 dias com coeficiente de varia??o de 7,95% e produ??o de leite de 6,1?2,58 litros por dia com coeficiente de varia??o de 41,96%. Foi encontrada margem bruta m?dia de R$ 32.514,51 ? R$ 20.905,58 com coeficiente de varia??o de 64,30% e margem l?quida m?dia de R$ 29.239,05 ? R$ 20.840,88 com coeficiente de varia??o de 71,28%, permitindo aos produtores permanecerem na atividade no curto prazo sendo poss?vel o pagamento do custo operacional efetivo. E resultado (preju?zo) na m?dia de - R$ 124.050,95 ? R$ 27.757,68 com coeficiente de varia??o de 22,38%. Por apresentar preju?zo, a receita obtida n?o remunera o investimento realizado, ou seja, o ativo financeiro imobilizado em patrim?nio como terras, benfeitorias e etc. Os baixos ?ndices zoot?cnicos referentes ? taxa de natalidade e produ??o de leite devem ser melhorados para obten??o de maiores receitas na atividade e melhor produ??o de leite. A maior porcentagem de participa??o na composi??o das receitas e nas despesas de investimento foi o valor imobilizado, quando contabilizado, e a venda do leite e a compra de animais, respectivamente, quando n?o contabilizado, o valor imobilizado. Com rela??o ?s despesas com custeio, as maiores porcentagens foram referentes ? m?o de obra, a pastagem, a alimenta??o concentrada e a suplementa??o volumosa. Os produtores analisados permanecem no curto prazo na atividade, por?m para aumentar a produ??o devem ter melhorados os ?ndices zoot?cnicos com maior utiliza??o da assist?ncia t?cnica para obten??o de maior retorno de efici?ncia econ?mica.
