Resumo: | The objective of this work was to evaluate the effectiveness of quicklime and shallow fermentation applications on the reduction of Clostridium perfringens and enterobacteria in recycled poultry litter, in dark house and conventional systems. Eighty litter samples were evaluated, being divided into four groups: litter treated with quicklime in dark house; litter treated with shallow fermentation and quicklime in dark house; and litter treated with quicklime in conventional broiler house; litter treated with shallow fermentation and quicklime in conventional broiler house. Samples were collected one day before slaughter and five days after litter treatment and were subjected to the quantitative microbiological analysis of enterobacteria and C. perfringens. The bacterial load in pre-treated litter was similar between the dark house and conventional systems. The groups treated only with quicklime showed a significant reduction of enterobacteria in both systems. The reduction of C. perfringens was only observed in the litter group treated with shallow fermentation and quicklime, in conventional broiler house. The use of 500 g m-² quicklime is the most effective method to reduce enterobacteria load in broiler litter both in the dark house and conventional broiler house systems. The combined treatment of shallow fermentation for seven days with the subsequent application of 500 g m-² quicklime is efficient for the reduction of C. perfringens in broiler litter, in conventional broiler house. |

Foram avaliadas 80 amostras de cama, divididas em quatro grupos: cama tratada com cal em “dark house”; cama tratada com fermentação rasa e cal em “dark house”; cama tratada com cal em aviário convencional; e cama tratada com fermentação rasa e cal em aviário convencional. As amostras foram coletadas um dia antes do abate e cinco dias após o tratamento da cama e foram submetidas à análise microbiológica quantitativa de enterobactérias e C. perfringens. A carga bacteriana antes do tratamento foi similar entre os sistemas “dark house” e convencional. Os grupos tratados somente com cal apresentaram redução de enterobactérias em ambos os sistemas. A redução de C. perfringens foi observada somente no grupo de cama tratada com fermentação rasa e cal em aviário convencional. O uso de 500 g m-² de cal virgem é o método mais eficaz para reduzir a carga de enterobactérias em cama de frango, tanto no sistema “dark house” como no convencional. O tratamento combinado de fermentação rasa por sete dias com a posterior aplicação de 500 g m-² de cal é eficiente para a redução de C. perfringens, em cama de frango, em aviário convencional.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBenedet, João PauloPerosa, Fernanda FelicettiSilva, Isabela Gimenes daTroncarelli, Marcella ZampoliRauber, Ricardo HummesGomes, Teane Milagres Augusto2021-02-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/26888Pesquisa Agropecuaria Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e02325Pesquisa Agropecuária Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e023251678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/26888/14847Direitos autorais 2021 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2022-05-18T18:27:35Zoai:ojs.seer.sct.embrapa.br:article/26888Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2022-05-18T18:27:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
