SILVEIRA, I.D. Barbosa et al. Simulation of economic feasibility and profitability of a free stall model milk production. Arq. Bras. Med. Vet. Zootec. [online]. 2011, vol.63, n.2, pp. 392-398. ISSN 0102-0935.  http://dx.doi.org/10.1590/S0102-09352011000200017.

The economical profitability and viability of the implantation of a milk production system in free stall were evaluated. A technical-market analysis was done to define the necessary investment as well as to determine the costs of each production factor. A production model with 100 lactating cows averaging 2,595 liters of daily production was considered. The total monthly operational cost was R$27,781.39 showing that nutrition is the variable with higher relevance (62.7% of the cost). For the monthly gross income a value of R$43,817.50 was obtained and, consequently, the monthly net income (NI)was R$16,030.11. A 12.2% profitability per year from NI rendering a deficit net value of R$131,627.39. Considering the estimated prices it is concluded that the proposed model was economically unfeasible.
