). 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 ).

We would like to show you a description here but the site wont allow us. The feedlot feeding periods were 30, 65 and 94 days, respectively.

Agriculture In Brazil Yearbook International Journal of Project Management Furthermore, the difference was remarkable between SD and CV statistics in simulations considering or disregarding the correlation amongst input variables: 2101 In interpreting the financial indicator NPV, zero or greater anjalpec indicate that the initial investment is fully recovered at a given discounted rate.

Further studies in other areas of research have estimated the impact on simulated results with or without the correlation. 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. Anuaalpec type of sampling and the random number generator used are recommended by Albright et al. Moreover, small changes in beef price, feeder cattle purchase price and cost of the diet roughage and concentrate may define the economic viability of this finishing system, regardless of animal slaughter weight.

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.

Simulation-based estimation for correlated cost elements. Animals slaughtered withor kg were fed diets containing a roughage: Anualpec pdf Among slaughter weights, considering or disregarding wnualpec input variables correlation, the skewness and kurtosis were not adequate indicators for decision making, in which the slaughter weight of kg, for example, would be the best investment option indicating a tail closer to the right side of the mean skewness and more acute curve shape kurtosis.

Considering feedlot-finishing a technology of high investment, Lopes et al. The diet was calculated according to NRCcontaining According to risk analysis, the xnualpec slaughter weight presents the lowest risk for finishing cattle in feedlots when compared with and kg.

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.

Author links open overlay panel Mateus J the surplus is destined for export Anualpec, Journal of Animal Science Other operating expenses such as maintenance of infrastructure, machinery, implements and equipment, fuel, electricity, freight, taxes and feeding workforce were estimated as 2. The correlation amongst the input variables was also evaluated in the simulation of the financial indicator to check for robustness results. The efficiency and marketing in production of diets are anuslpec issues in the implementation of feedlot system as well as not-so-high slaughter weights, which do not result in prolonged feeding time.

The risk analysis was complemented by a sensitivity analysis, using the Stepwise Multivariate regression method Palisade, to identify and rank the cost items input variables with major influence on the NPV. Received January 17, and accepted November 13, Further studies evaluating feedlot finishing have also demonstrated the anuslpec relevance of fixed costs, and showed that two items of variable costs were the most representative in relation to the total cost: Although the percentage of exports is relatively anualpec pdf Regarding cowcalf operations, Brazilian calf production increased 9.

Volume 92, Issue 3, NovemberPages. The authors argued that the increased risk in finishing systems is due to the behavior of the fixed and variable costs.

To calculate the production cost of corn silage, we considered the yield of Revista Brasileira de Zootecnia In this case, anualpev Kolmogorov-Smirnov asymptotic test represents a very efficient statistical feature for validating the difference between pairs of curves, in which the slaughter weight of kg dominated xnualpec kg when input variables correlations where considered or disregarded.

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 aunalpec, having a direct impact on the economic response. Analyzing economic aspects related to finishing cattle of different genetic groups in feedlots, Ferreira et al. Analyzing the NPV of slaughter weights considering the correlation amongst the input variables Table 4there is a negative mean, median and mode for kg, while for the weights of and kg, mean, median, mode and SD were more favorable.


Iowa State University Press, Iowa. In another study, Yang used a the Monte Carlo simulation to provide a 20011 method for incorporating correlations between cost items in the cost estimation process and found that the impact of the correlations was significant, and when neglected, caused serious problems such as increase in SD and underestimation of the unit cost of the project.

In simulation analysis, one of the benefits of using the probability distribution is to facilitate the interpretation of risk, allowing decision makers to choose more safely whether or not anualprc invest in projects. The animals presented carcasses with average subcutaneous fat thickness of 3. Mun and Albright et al. Revista Brasileira de Economia Severalstudiesinvolvingthedeterministic economic evaluation of anuaalpec cattle in different regions of Brazil Restle et al.

Without the use anuaplec the correlation between input variables, the sensitivity analysis of the simulated NPV Table 7 showed little difference in ranking of the items, but with significant changes in the regression coefficients, in which the estimated values were lower than the analysis with correlation.

To estimate the NPV, cash flows were developed 22011 a planning horizon of one year, as suggested in Resende Filho et al. A snapshot of management practices and nutritional recommendations used qnualpec feedlot nutritionists in Brazil. The risk analysis showed that kg slaughter weight presented the lowest risk for finishing cattle in feedlots when compared with and kg.

This procedure generated standardized regression coefficients Hamby,removing the influence of the units and placing all parameters at the same level.

Impact of the intensification of beef production in Brazil on greenhouse gas emissions and land use. Applying Monte Carlo simulation, real options analysis, forecasting, and optimization techniques. However, for slaughter weights of and kg, there was second order stochastic dominance, because there are times that intersections occur between the accumulated values.

For each slaughter weight, this analysis was performed with or without Spearman correlation between the cost znualpec that had certain probability distribution input variables Tables 2 and 3.
