Avaliou-se o custo de inclusão da polpa cítrica em programa de restrição alimentar qualitativa, utilizando dados de desempenho de 36 suínos da linhagem Topigs, dos 83,7±5,1kg aos 129,8±1,9kg de peso, alimentados com dietas contendo porcentagens crescentes (0, 10, 20 e 30%) de polpa cítrica. Os animais foram abatidos aos 130kg e dos valores (R$) da carcaça foram descontados o valor de compra dos animais e o custo com alimentação, de acordo com cada tratamento. Não houve efeito (P>0,05) da inclusão da polpa cítrica sobre o custo com ração e receita bruta, porém houve efeito linear negativo (P0.05) of the inclusion of citrus pulp on ration cost and gross income was observed. A negative linear effect (<0.05) on partial net income with the increasing participation of the citrus pulp in diets was found. The decreasing trend in the partial net income was caused by the reduction on carcass weight of animals fed on crescent levels of citrus pulp. Considering the increase on corn, soybean, and swine prices from June 2005 to May 2006, 12 different sceneries were determined for partial net income analysis. In all situations, linear reductions on partial net income were observed as a function of citrus pulp inclusion, evidencing that the ingredient was not efficient in promoting profits for producers
Avaliou-se economicamente o efeito da inclusãode 0, 5, 10 e 15% de polpa cítrica (PC), com ou sem adição do complexo enzimático, sobre o desempenho de 72 suínos, dos 25,71±7,51 aos 98,81±10,64kg de peso.

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.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq
