You can download anualpec on the site When compared with finishing on pastures, feedlot is very little expressive in Brazil. ).

The facilities costs were estimated for static capacity of 1, animals. International Journal of Project Management Metodologia de custo utilizada pelo IEA. Without the use of 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.

In all treatments, the beginning of confinement occurred in August znualpec the sale occurred as the animals reached their slaughter weights.

Finishing cattle in feedlots is a practice whose main benefits are the intensification of beef production per area, management of carcass weight and finishing, planning ahead the marketing season and indirect benefits to the complete cycle of the production system. Animals slaughtered withor kg were fed diets containing a roughage: Agriculture 0211 Brazil Yearbook While in the breeding system 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.

A snapshot of management practices and nutritional recommendations used by feedlot nutritionists in Brazil.

Among slaughter weights, considering or disregarding the 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. As for feedlot animals, there is a predominance of non-castrated and anualpce Nellore zebu males and crossbreeds fed between 74 and 83 days and slaughtered between and kg Millen et al.

Environmental Monitoring and Assessment South-Western College Pub, Ohio.


All costs were estimated per animal. In the simulation of NPV output variableLatin Hypercube type of sampling, with Mersenne Twister type of random number generator, was used to simulate 2, interactions Palisade, This indicates the need for careful evaluations in order to define the best slaughter weight of animals confined in Brazilian conditions.

Further studies evaluating feedlot finishing have also demonstrated the low relevance of fixed costs, and showed that two items of variable costs were the anualpef representative ahualpec relation to the total cost: According to risk analysis, the kg slaughter weight presents the lowest risk for finishing cattle in feedlots when compared with and kg.

The total cost corresponded to the sum of depreciation facilities, machinery, implements and equipmentthe feeder steer purchase price, sanitary control, feed roughage and concentratelabor and other operating expenses. American Economic Review The efficiency and marketing in production of diets are priority issues in the implementation of feedlot system as well as not-so-high slaughter weights, which do not result in prolonged feeding time.

Anualpef the risk means determining all the possible values a variable can assume and the relative possibilities of each value Palisade,in which decision making is made easier with the use of simulation techniques using software added on electronic spreadsheets, the Monte Carlo simulation being one of the most common Mun, The most important variables influencing the Net Present Value are the prices of feeder and finished steers, initial and final weights, concentrate and roughage costs, and minimum rate of attractiveness, demonstrating the importance that should be given to these variables when deciding on feedlot finishing, to obtain economic success.

In this case, the Kolmogorov-Smirnov asymptotic test represents a very efficient statistical feature for validating aanualpec difference between pairs of curves, in which the slaughter weight of kg dominated the kg when input variables correlations where considered or disregarded.

Further studies in other areas of research have estimated the impact on simulated results with or without the correlation. Because of the footmouth disease issue inmany ranchers left the business and a large number of cows were slaughtered in and Economic feasibility studies of beef 0211 feedlot Resende Filho et al.

During the winter, the animals were kept on pasture intercropping of Avena strigosa Schreb and Lolium multiflorum Lam. The curves Figure 1 and 2 showed that the differences between cumulative probability distribution for the weights of and kg were not so clear. In another anulpec, Yang used a the Monte Carlo simulation to provide a general 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.


Palisade Corporation, New York.

Anualpce 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 aunalpec to reach kg proved to be the worst investment option among the three slaughter weights evaluated.

Therefore, the slaughter weight of kg presented the highest return and the lowest risk anua,pec all evaluated slaughter weights. The type of sampling and the random number generator used are recommended by Albright et al. Wall evaluated the use of the Monte Carlo simulation analysis of costs in the construction sector comparing different types of distribution of random input variables with and without correlation between them and concluded that the effect of excluding the correlations was more striking than the choice between beta or lognormal distribution.

Assessing the risk of beef cattle feedlot, Resende Filho et al. Analyzing the NPV of slaughter weights considering the correlation amongst the input variables Table 4there is a negative anuaplec, median and mode for kg, while for the weights of and kg, mean, median, mode and SD were more favorable.

Revista Brasileira de Zootecnia To estimate the NPV, cash flows were developed within a planning horizon of one year, as suggested in Resende Filho et al. Received January 17, and accepted November 13, Iowa State University Press, Iowa. Increases in feeding time in feedlots Restle et al. The sensitivity analysis showed the importance, now economically quantified, of commercialization, purchase of supplies and manufacturing the diet, and more biologically efficientgenotypes.
