Resumo: The objective of this study was to evaluate the chemical-bromatological composition of elephant grass (EG) silages with the addition of acerola by-product (ABP). The experimental design was completely randomized, with five treatments: Treatment 1 = 100% EG; Treatment 2 = 94% EG + 06% ABP; Treatment 3 = 88% EG + 12% ABP; Treatment 4 = 82% EG + 18% ABP and Treatment 5 = 76% EG + 24% ABP, with four replications (silos). EG and ABP were mixed at the time of ensiling. The silos were open at 42 days and samples were collect for chemical analysis. The addition of up to 24% of ABP in EG silage significantly (P<.05) increases the pH, dry matter (DM) and crude protein levels, thus providing fermentations within desirable standards. The estimated dry matter intake, neutral detergent fiber (NDF), ash and ethereal extract of EG silage was not influenced by ABP. Total digestible nutrients, total carbohydrates, hemicellulose and estimated DM digestibility decreased linearly. The high levels of NDF and acid detergent fiber of the ABP compromise the DM digestibility, reducing the nutritional value of the silages.

El diseño experimental fue completamente al azar, con cinco tratamientos: Tratamiento 1 = 100% PE; Tratamiento 2 = 94 % PE + 06 % RA; Tratamiento 3 = 88% PE + 12% RA; Tratamiento 4 = 82% PE + 18% RA y Tratamiento 5 = 76% PE + 24% RA, con cuatro repeticiones (silos). PE y RA se mezclaron en el momento del ensilaje. Los silos se abrieron a los 42 días y se recogieron muestras para análisis químico. La adición de hasta un 24 % de RA en el ensilaje PE aumenta significativamente (P<0.05) el pH, la materia seca (MS) y los niveles de proteína cruda, proporcionando así fermentaciones dentro de los estándares deseables. El consumo estimado de MS, fibra detergente neutro (FDN), cenizas y contenido de extracto etéreo del ensilaje PE no se vieron influenciados por la adición de RA. Los contenidos de nutrientes digestibles totales, carbohidratos totales, hemicelulosa y digestibilidad estimada de MS disminuyeron linealmente. Los altos niveles de FDN y FDA de RA comprometen la digestibilidad de la MS, disminuyendo el valor nutricional de los ensilajes.Objetivou-se neste estudo avaliar a composição química-bromatológica da silagem de capim-elefante (CE) com adição de níveis crescentes de resíduo da acerola (RA). O delineamento experimental foi inteiramente ao acaso, com cinco tratamentos: Tratamento 1 = 100% CE; Tratamento 2 = 94% CE + 06% de RA; Tratamento 3 = 88% CE + 12% de RA; Tratamento 4 = 82% CE + 18% de RA e Tratamento 5 = 76% CE + 24% RA, com quatro repetições (silos).  O CE e o RA foram misturados no momento da ensilagem. Os silos foram abertos com 42 dias e colhidas amostras para análises químicas-bromatológicas. A adição de até 24% do RA na ensilagem de CE aumenta significativamente (P<0,05) os níveis de pH, de matéria seca (MS) e de proteína bruta, provendo assim, fermentações dentro dos padrões desejáveis. A estimativa de consumo de MS, os teores de fibra em detergente neutro (FDN), cinzas e extrato etéreo da silagem de CE não foram influenciados pela adição do RA. Os teores de nutrientes digestíveis totais, carboidratos totais, hemicelulose e a estimativa de digestibilidade da MS decresceram linearmente. Os elevados níveis de FDN e FDA do RA comprometem a digestibilidade da MS diminuindo o valor nutritivo das silagens.Research, Society and Development2023-02-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/4034210.33448/rsd-v12i3.40342Research, Society and Development; Vol. 12 No. 3; e3912340342Research, Society and Development; Vol. 12 Núm. 3; e3912340342Research, Society and Development; v. 12 n. 3; e39123403422525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/40342/33020Copyright (c) 2023 João Avelar Magalhães; Braz Henrique Nunes Rodrigues ; Francisco José de Seixas Santos ; Newton de Lucena Costa; Roberto Cláudio Fernandes Franco Pompeuhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMagalhães, João Avelar Rodrigues , Braz Henrique NunesSantos , Francisco José de Seixas Costa, Newton de Lucena Pompeu, Roberto Cláudio Fernandes Franco2023-03-23T08:33:38Zoai:ojs.pkp.sfu.ca:article/40342Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2023-03-23T08:33:38Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
