Resumo: | The objective of this work was to evaluate the effect of diets with cottonseed and vitamin E on the greenhouse gas (GHG) emissions of cattle feces analyzed in biodigesters. Animal feces were evaluated in 18 laboratory-scale anaerobic digesters through the following treatments: control, feces from cows fed with a control diet; CS, feces from cows fed with a cottonseed diet; and CSVitE, feces from cows fed with a cottonseed and vitamin E diet. The production of biogas and GHG was measured, and no differences were observed for the emissions of biogas, methane (CH4), and nitrous oxide (N2O). The partition of the gross energy of the anaerobic digestion process was similar among treatments. On average, 28% of gross energy fed was released as CH4, 47% during digestion, and 25% as other gases and heat. The addition of cottonseeds to the cattle diet increases the concentration of CH4 and reduces that of CO2, but it does not affect the total production of CH4, CO2, and N2O in the biodigesters. The inclusion of vitamin E in the diet has no effect on GHG production in the biodigesters. |

As fezes dos animais foram avaliadas em 18 digestores anaeróbios de laboratório, por meio dos seguintes tratamentos: controle, fezes de vacas alimentadas com dieta controle; CS, fezes de vacas alimentadas com caroço de algodão; e CSVitE, fezes de vacas alimentadas com caroço de algodão e vitamina E. As produções de biogás e GEE foram medidas, e não foram observadas diferenças para as emissões de biogás, metano (CH4) e óxido nitroso (N2O). A partição da energia bruta do processo de digestão anaeróbica foi semelhante entre os tratamentos. Em média, 28% da energia bruta alimentada foi liberada como CH4, 47% na digestão e 25% como outros gases e calor. A adição de caroços de algodão na dieta de bovinos aumenta a concentração de CH4 e reduz a de CO2, mas não afeta a produção total de CH4, CO2 e N2O nos biodigestores. A inclusão de vitamina E na dieta não tem efeito na produção de GEE nos biodigestores.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFundação de Amparo à Pesquisa do Estado de São PauloNogueira, Ricardo Galbiatti SandovalPerna Junior, FlavioTseu, Ramos JorgeRodrigues, Paulo Henrique Mazza2023-05-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/27291Pesquisa Agropecuaria Brasileira; V.58, Jan./Dec., 2023: Publicação contínua em volume anual; e03037Pesquisa Agropecuária Brasileira; V.58, Jan./Dec., 2023: Publicação contínua em volume anual; e030371678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/27291/15153Direitos autorais 2023 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2023-12-14T19:05:00Zoai:ojs.seer.sct.embrapa.br:article/27291Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2023-12-14T19:05Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
