ECONOMIC DETERMINISTIC ANALYSIS OF TWO YEARS OLD STEERS PRODUCTION SYSTEMS

Abstract

Abstract The objective of this study was to realize the economic deterministic analysis of steers production system in full cycle, finished in feedlot or cultivated pasture at twenty-four months old, utilizing or not the quality bonus from slaughterhouses. The study was realized using data from meta-analytic survey of studies in the central region of Rio Grande do Sul state, Brazil, in Microsoft Excel® spreadsheets. The systems were simulated considering the male and female calves weaned early, at the tree months of age, and finished at the 24 months of age in feedlot or cultivated pasture. After the slaughter, it was realized the economic deterministic analysis. According to financial return indicators net present value (NPV), benefit:cost index (IB:C) and additional return on investment (ROI) only the system in pasture show return at the end of planning horizon, and the internal return rate (IRR), modified internal return rate (MIRR) and discounted payback (PBd), show that this system possesses a higher risk of investment. The feedlot system show negative results as a investment project. The bigger cost center was depreciation, feeding supply and taxes, and the quality bonus shows up an interesting alternative of return, but was not sufficient to render the feedlot system a viable project.
