). Altought most of brazilian beef production comes from grazing systems, ), representing almost 10% of the slaughters in Brazil (ANUALPEC, ). Description. You can download anualpec on the site When compared with finishing on pastures, feedlot is very little expressive in Brazil. ). It accounted for the largest bovine herd in the country in . accounts for % of calves produced in Brazil (ANUALPEC ).

Considering feedlot-finishing a technology of high investment, Lopes et al. Material and Methods Information of animal performance and experimental diet roughage and concentrate was used in the calculations of production costs as well as in the simulation of financial indicator.

Revista Brasileira de Anaulpec We would like to show you a description here but the site wont allow us. Simulations of NPV considering the correlation amongst the input variables produced more consistent estimates of this financial indicator than simulations that disregarded it. The correlation amongst the input variables was also evaluated in the simulation of the financial indicator to check for robustness results.

Metodologia de custo utilizada pelo IEA. Moreover, small changes in beef price, feeder 2011 purchase price and cost of the diet roughage and concentrate may define the economic viability of this finishing system, regardless of animal slaughter weight. Strategies to promote farm animal welfare in Latin America and their effects on carcass and meat quality traits.

Information of animal performance and experimental diet roughage and concentrate was used in the calculations of production costs as well as in the simulation of financial indicator. In the criterion of stochastic dominance of first order, investments for investors who prefer higher returns are selected; in the stochastic dominance of second order, selected investments for investors who prefer high returns and low risk are selected.


In practice, the sensitivity analysis presented in this study demonstrates the importance of technical efficiency in the management of feedlots as an alternative for finishing beef cattle, having a direct impact on the economic response.

Furthermore, the difference was remarkable between SD and CV statistics in simulations considering or disregarding the correlation amongst input variables: The animals presented carcasses with average subcutaneous fat thickness of 3. The intended slaughter weights wereand kg, and the actual slaughter weights wereand kg, respectively.

This procedure generated standardized regression coefficients Hamby,removing the influence of the units and placing anhalpec parameters at the same level. International Journal of Project Management This indicates the need for careful evaluations in order to define the best slaughter weight of animals confined in Brazilian conditions.

For each slaughter weight, this analysis anual;ec performed with or without Spearman correlation between the cost items that had certain probability distribution input variables Tables 2 and 3. Nutrient requirements of beef cattle. Agriculture In Brazil Yearbook Further studies in other areas of research have estimated the impact on simulated results with or without the correlation. Journal of Animal Science All costs were estimated per animal.

The most important variables influencing the NVP are the prices of feeder and finished steers, initial and final weights, concentrate and roughage costs, and minimum rate of attractiveness; therefore, farmers should pay particular attention to these variables when making the decision of whether or not to use feedlot to finish beef cattle.


The diet was calculated according to NRCcontaining The interpretation of the statistics of the simulated NPV Table 3 is of great value in decision making; regardless of whether or not the correlation is used, feeding animals to reach kg proved to be the worst investment option among the three slaughter weights evaluated.

As for feedlot animals, there is a predominance of non-castrated and castrated Nellore zebu males and crossbreeds fed between 74 and 83 days and slaughtered between and kg Millen et al. However, slaughter weights starting from kg are common and accepted by the industry, provided they have proper carcass fattening above three mm of subcutaneous fat thickness. However, for slaughter weights of and kg, there was second order stochastic dominance, because there are times that intersections occur between the accumulated values.

Using the correlation to simulate NPV, it can be noted that in the analyzed slaughter weights, the seven most important items were, in order of importance, the price of finished steers, price of feeder steers, final weight, initial weight, concentrate cost, roughage cost, and minimum rate of attractiveness Table 6.

Applying Monte Carlo simulation, real options analysis, forecasting, and optimization techniques.
