Indicadores chaves de desempenho de fazendas produtoras de leite nos estados de Minas Gerais e Rio de Janeiro

Abstract

The objective of this work was to determine and quantify key performance indicators of dairy farms and to define which of them have greater impact on profitability. The sample was composed of 61 dairy farms in the states of Minas Gerais and Rio de Janeiro. Descriptive statistics were used to describe the database. A complete linear model was generated, with profitability being the dependent variable and indicators assessed the independent variables. Was used the Stepwise method and the criterion of stop was the Akaike criterion. All statistical procedures were performed using the free software R Project. The final linear model showed ² = 83,12, without abnormality of the data by residual analysis.Milk production per cow in milk, cost of labor per feeding cost, gross income from milk per gross total income, total operating cost per total gross income, total cost of feeding per total cost and total unit cost per price of milk were the variables used to explain the profitability of the sampled herds.
