Resumo: | The objective of this study was to determine the chemical composition and apparent metabolizable energy (AME), AME corrected for nitrogen balance (AMEn) and its respective metabolizable coefficients of animal byproducts for broiler chickens with different ages. Meat and bone meal, poultry by-product meal, tilapia processing residue and poultry fat were evaluated. A total of 760 male broiler chickens were used and evaluated and the phases: pre-starter (1 to 8 d of age); starter (11 to18 d); grower 1 (21 to 28 d); grower 2 (31 to 38 d), and finisher (41 to 48 d). Total excreta collection method was performed in five metabolism assays. The experimental design was completely randomized, and data were submitted to analysis of variance, posteriorly, the four feeds were compared by Tukey test and a regression analysis was performed with broiler chickens age. The significance was considered at 5% probability. The values of AME and AMEn were higher in older birds for all ingredients. The lesser CAME and CAMEn were obtained for meat and bone meal, for the regression analysis poultry by-product meal, tilapia processing residue and poultry fat had an increased linear effect with birds age and there was no adjust for meat and bone meal for regression analysis. |

Los cuatro alimentos evaluados fueron harina de carne y huesos, harina de vísceras, harina del residuo del procesamiento de tilapia y grasa de ave. Se utilizaron y evaluaron un total de 760 pollos de engorde machos en las fases: preinicial (1 a 8 días de edad), crecimiento 1 (21 a 28 días); crecimiento 2 (31 a 38 días) y terminación (41 a 48 días). El método de recolección total de heces se llevó a cabo en cinco ensayos de metabolismo. El diseño experimental fue completamente aleatório, los datos fueron sometidos a análisis de varianza y los cuatro alimentos se compararon mediante la prueba de Tukey, también se realizó un análisis de regresión para la edad de las aves, la significancia se consideró al 5% de probabilidad. Los valores de EMA y EMAn fueron mayores en aves con edades más avanzadas para todos los ingredientes y los coeficientes de metabolizabilidad más bajos ocurrieron en la harina de carne y huesos. En el análisis de regresión, los valores energéticos de la harina de vísceras, harina de residuos de procesamiento de tilapia y grasa de ave mostró un aumento lineal con la edad de las aves y no hubo ajuste para la harina de carne y huesos.O objetivo deste estudo foi determinar a composição química e energia metabolizável aparente (EMA), EMA corrigida para o balanço de nitrogênio (EMAn) e respectivos coeficientes de energia metabolizável de subprodutos de origem animal em frangos de corte de diferentes idades. Os quatro alimentos avaliados foram: farinha de carne e ossos, farinha de vísceras, farinha do resíduo do processamento da tilápia e gordura de aves. Um total de 760 frangos de corte machos foram utilizados e avaliados nas fases: pré-inicial (1 a 8 dias de idade), crescimento 1 (21 a 28 dias); crescimento 2 (31 a 38 dias) e terminação (41 a 48 dias). Foi realizado o método de coleta total em cinco ensaios de metabolismo. O delineamento experimental foi inteiramente casualizado e os dados foram submetidos à análise de variância e as médias dos quatro alimentos foram comparados pelo teste de Tukey, também foi realizada análise de regressão para a idade das aves, a significância foi considerada a 5% de probabilidade. Os valores de EMA e EMAn foram maiores nas aves com idades mais avançadas para todos os ingredientes e os menores coeficientes de metabolizabilidade ocorreram na farinha de carne e ossos. Na análise de regressão os valores energéticos da farinha de vísceras, farinha do resíduo do processamento de tilápia, e gordura de aves apresentaram um aumento linear com a idade das aves e não ocorreu ajuste para a farinha de carne e ossos.Research, Society and Development2021-06-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1563910.33448/rsd-v10i6.15639Research, Society and Development; Vol. 10 No. 6; e37110615639Research, Society and Development; Vol. 10 Núm. 6; e37110615639Research, Society and Development; v. 10 n. 6; e371106156392525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/15639/14207Copyright (c) 2021 José Luiz Schneiders; André Sanches de Avila; Jomara Broch; Rafael Frank; Rodrigo André Schöne; Tiago Rafael Hofferber; Guilherme Luis Silva Tesser; Edinan Hagdon Cirilo; Nilton Rohloff Junior; Cleison de Souza; Ricardo Vianna Nuneshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSchneiders, José Luiz Avila, André Sanches de Broch, Jomara Frank, RafaelSchöne, Rodrigo André Hofferber, Tiago Rafael Tesser, Guilherme Luis Silva Cirilo, Edinan Hagdon Rohloff Junior, NiltonSouza, Cleison deNunes, Ricardo Vianna 2021-06-10T22:51:46Zoai:ojs.pkp.sfu.ca:article/15639Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:36:25.034439Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
