Resumo: | Eight experiments were carried out involving 24 roosters, three feedstuffs, six replicates, being in each experimental unit, a rooster. Prior to each experiment the birds were starved for 36 hours to empty their digestive tract. At the beginning of each assay the roosters were individually weighed and then force fed the exact amount of 30 grams of feedingstuff. Force feeding was performed by inserting a tube in to the crop via the oesophagus. After feeding, the birds were returned to their cages. A tray was placed under each cage to collect excreta. At the same time six roosters were kept fasting to take account of metabolic fecal energy and endogenous urinary energy. Exactly 48 h after force feeding, the voided excreta was collected quantitatively and processed in laboratory. The apparent metabolizable energy (AME), N-corrected metabolizable energy (MEn), true metabolizable energy (TME), and N-corrected true metabolizable energy (TMEn) values of the feedingstuffs, in Kcal/g, expressed on air dry basis, were, respectively: algaroba meal, 1.26, 1.46, 1.74 and 1.73; defated rice bran meat, 1.21, 1.37, 2.22 and 2.22; full-fat rice bran meal 2.51; 2.70, 3.09 and 2.79, incubatory waste meal 1.29, 1.37, 1.63 and 1.47; dendê meal 1.40, 1.69, 2.08 and 1.91; guar seed 0.94, 1.29, 1.37 and 1.33; integral cassava meal 2.82, 3.01, 3.34 and 3.27; cassava meal 1.40, 1.76, 2.64 and 2,65; corn gluten meal 3.53, 3.62, 4.33 and 3.95; ground corn 3.04, 3.24, 3.65 and 3.50; fish meal 2.65, 2.22, 2.57 and 2.50; soybean meal 2.08, 2.17, 2.65 and 2.51; high-tannin sorghum grain 2.47, 2.75, 3.04 and 3.02; low-tannin sorghum grain 2.90, 3.10, 3.47 and 3.38 and wheat meal 1.26, 1.50, 2.06 and 1.88. Because of the correction of the metabolic and endogenous losses, the TME and TMEc values were higher than AME and AMEn values. |

No início dos experimentos, os galos foram alojados em gaiolas individuais e mantidos em jejum por um período de 36 horas, para esvaziar seus tratos digestivos. Em seguida, foram pesados e forçados a consumir uma quantidade de 30 g de alimento, introduzido dentro do papo através de um funil colocado no esôfago. Após a alimentação, os galos retornaram para as gaiolas providas de bandejas para coleta de fezes. Paralelamente, seis galos permaneceram em jejum, para se determinar as perdas endógenas e metabólicas. Durante as 48 horas após a alimentação forçada, as fezes foram coletadas com intervalo de 24 horas. Os valores médios de energia metabolizável aparente (EMA), energia metabolizável aparente corrigida (EMAn), energia metabolizável verdadeira (EMV) e energia metabolizável verdadeira corrigida (EMVn) dos alimentos expressos em Kcal/g de matéria natural foram, respectivamente: farinha de algaroba, 1,26; 1,46; 1,74 e 1,73; farelo de arroz desengordurado, 1,21; 1,37; 2,22 e 2,22; farelo de arroz integral, 2,51; 2,70; 3,09 e 2,79; farelo de resíduo incubatório, 1,29; 1,37; 1,63 e 1,47; torta de dendê, 1,40; 1,69; 2,08 e 1,91; semente de guar moída, 0,94; 1,29; 1,37 e 1,33; farinha de mandioca integral, 2,82, 3,01, 3,34 e 3,27; farelo de raspa mandioca, 1,40, 1,76, 2,64 e 2,65; farinha de glúten milho, 3,53, 3,62, 4,33 e 3,95; milho moído, 3,04, 3,24, 3.65 e 3,50; farinha de peixe, 2,65, 2,22, 2,57 e 2,50; farelo de soja, 2,08, 2,17, 2,65 e 2,51; sorgo moído de alto tanino, 2,47, 2,75, 3,04 e 3,02; sorgo moído de baixo tanino, 2,90, 3,10, 3,47 e 3,38, e farelo de trigo, 1,26, 1,50, 2,06 e 1,88. Em função da correção dos valores energéticos pelas perdas endógenas e metabólicas, os valores de EMV e EMVn foram superiores aos de EMA e EMAn.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAlbino, Luiz F.
