ANÁLISE ECONÔMICA DETERMINÍSTICA DA TERMINAÇÃO EM CONFINAMENTO DE NOVILHOS ABATIDOS COM DISTINTOS PESOS

The aim of this study was to evaluate the economic viability of feedlot-finished steers through financial indicators of risk and return, via deterministic analysis, based on average values quotations practiced in Rio Grande do Sul state in the years 2004-2012. We used 18 Charolais steers with average initial age of 30 months and average initial weight of 297.0kg ± 11.5kg. We evaluated three predetermined slaughter weights: 420, 460 and 500kg, being the weights obtained of 421, 461 and 495kg, respectively. Variable costs represented 98% of total cost, and of these, the most representative were purchase of feeder cattle and food (forage + concentrate). The estimates of the financial indicators to slaughter weights of 421, 461 and 495kg were, respectively: R$-266.30, -323.49 and -417.18 for gross margin; R$ -289.70, -440.59 and 346.90 for net margin; R$-344.89, -419.93 and -536.24 for profit; R$ -316.78, -381.92 and -483.67 for net present value; 0.85, 0.83 and 0.81 for index benefit:cost, -2.65%, -2.52% and -2.58% for additional return on investment; -5.02%, -4.57% and -4.56% for the internal rate of return (a.m.); and 7.05, 8.37 and 9.86 months for discounted payback. Although these results indicate infeasibility of termination at any slaughter weight, lower weights resulted in lower economic losses, making this technology of high economic risk

Deterministic economic analysis of feedlot Red Angus young steers: slaughter weights and bonus

The joint analysis of indicators of the investment project is very relevant in making decisions, resulting in more consistent information regarding risk assessment and its confrontation with the possibility of return. This research aimed to evaluate the economic feasibility of Red Angus young steers finished in feedlot, slaughtered at 340, 373, 396 or 430kg with use of various financial indicators, marketed with or without bonus. The purchase of feeder cattle and feeding were variable costs with a higher share in the total cost. In the analysis with bonus, the regression analysis to gross margin, net margin, net present value, benefit:cost index and additional return on investment showed quadratic behavior, with the point of maximum at 406kg (R$185.17), 406kg (R$ 161.76) , 393kg (R$128.29), 392kg (1.12), 392kg (11.98$ 110.31 and R$ 86.90, respectively), while for the other indicators, there was a linear reduction as an increase in slaughter weight
