Previous issue date: 2003-09-15 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / Com o objetivo de determinar os valores de energia metabolizável aparente corrigida (EMA n ), os coeficientes de digestibilidade aparente (CDA) e estimar os valores de energia líquida (EL) de 27 alimentos, foram realizados 4 ensaios no Setor de Avicultura da Universidade Federal de Viçosa. Eles foram divididos em alimentos de origem vegetal energético, de origem vegetal protéicos, de origem animal e por outros alimentos. Os alimentos de origem vegetal energético foram constituídos por duas amostras de trigo, duas de milho, duas de farelo de trigo (FT), uma de sorgo e uma de farelo de glúten de milho 21% (FGM21). Os de origem vegetal protéico foram constituídos por duas amostras de farelo de soja (FS), uma de soja integral tostada (SIT), uma de farelo de glúten de milho 60% (FGM60), e uma de farelo de algodão 30% (FA). Os de origem animal foram constituídos por três amostras de farinha de penas (FP), três de farinha de vísceras de aves (FVA), duas de farinha de vísceras suínas (FVS), duas de farinha de carne e ossos (FCO), e uma de farinha de penas e vísceras (FPV). Finalmente, outros alimentos foram constituídos por amido, açúcar e óleo de soja. Para determinar os valores de EMA n , foi utilizado o método da coleta total de excretas e para determinar os CDA, foi utilizado o método do indicador. Pela composição química dos alimentos e os CDA, foi calculado o valor de EL. Os valores de EMA n expressos em kcal/kg de MS, foram em média de 3.767 para o milho, de 3.275 para o trigo, de 1.995 para o FT, de 2.259 para o FS, de 3.464 para o sorgo, de 1.901 para o FGM21, de 3.721 para o FGM60, de 3.072 para a SIT, de 2.012 para o FA, de 3.516 para o amido, de 3.651 para o açúcar e de 7.721 para o óleo de soja. Os valores de EMA n expressos em kcal/kg de MS, foram em média, para os alimentos FCO, FP, FVA, FVS e FPV, respectivamente, de 1.422, 1.875, 2.844, 1.779 e 2.209.

The feedstuffs were classified in energetic, proteins, animal proteins and other feeds. The energetic feeds were a mix of wheat, corn and wheat bran (WB), two batches of each, plus one batch of sorghum and one of corn gluten meal with 21% CP (CGM21). The protein feeds were made of two batches of soybean meal (SM), and one batch of toasted integral soybean (TIS), other of corn gluten meal with 60% CP (CGM60) and another of cottonseed meal 30% CP (CM). The protein feeds of animal origin were made of three batches of feathers meals (FM), three batches of poultry viscera meals (PVM), two batches of swine viscera meals (SVM), two batches of meat and bone meals (MBM), plus one batch of viscera and feathers meal (VFM). Finally, other feeds were made of corn starch, sugar xiiand soybean oil (OS). To determine the values of AME n , the total excrete collection method was used and to determined the values of ADC, the indicator method was used. With the data of feedstuff chemical compositions and also the ADC, the values of NE were calculated.
