摘要

An economic evaluation was done in order to evaluate the effect of the inclusion of 0, 5, 10 and 15% of citrus pulp (PC), with or without the addition of the enzyme complex, on the performance of 72 pigs from 25.71?±7.51 to 98.81?±10.64kg of body weight. The animals were slaughtered when they reached 98.81kg. The purchase value of the animals and feed costs (R$) were discounted from the carcass value, including subsidy rates (R$). A linear increase (P= 0.0190) was observed, while linear reductions were observed for the gross receipts (P= 0.0328) and net (P = 0.0013) partials, due to the inclusion of PC in the diet with or without the enzyme complex. Considering the evolution of corn, soybean meal and pig prices during 2008, there were some 12 different scenarios for partial and net income determined and in all of them, linear reductions were observed due to the inclusion of PC in the diet with or without the enzyme complex. The use of PC with or without the addition of the enzyme complex was unable to reduce the costs of feed.
