Resumo: | The present work aims to verify whether the autolyzed Saccharomyces cerevisiae reduces total coliforms, Escherichia coli and Salmonella spp. from the hide, feces and carcass of feedlot-finished steers. Eighteen half-Angus steers were subjected to three treatments daily for 105 days: control (n=6), Lev 4 g (diet with 4 g yeast animal day-1, n=6) or Lev 7 g (diet with 7 g yeast animal day-1, n=6). On Days 29 and 90 after entrance into the feedlot, fecal samples, skin swabs, water and food were collected to identify and count E. coli and total coliforms and identify Salmonella spp. On the day of slaughter, carcasses were collected to identify and quantify E. coli, total coliforms, and mesophiles. There were reductions in E. coli and total coliforms in fecal samples (P=0.0001 and 0.001, respectively) and mesophilic aerobics in carcasses (P= 0.05) in the treated groups, and no Salmonella spp. was observed in any of the samples collected. It was concluded that supplementation reduced fecal excretion of and, consequently, carcass contamination by E. coli, mesophiles and total coliforms in confined animals and that this technique is a beneficial and residue-free sanitary measure to improve the microbiological quality of meat. |

Para tanto, 18 novilhos, ½ sangue Angus foram submetidos a três tratamentos diários durante 105 dias: controle (n=6), Lev4g (dieta com 4 g de levedura por animal dia-1, n=6) ou Lev 7g ( dieta com 7 g de levedura por animal dia-1, n=6). Nos dias 29 e 90 após a entrada no confinamento, coletou-se amostras de fezes, swab de pele, água e alimento para contagem de Escherichia coli e coliformes totais e isolamento de Salmonella spp. No dia do abate, realizou-se coleta nas carcaças para identificação de Salmonella spp e quantificação de Escherichia coli, coliformes totais, mesófilos. Notou-se redução de Escherichia coli e coliformes totais nas amostras de fezes (P=0,0001 e 0,001 respectivamente) e de Escherichia coli, coliformes totais e aeróbios mesófilos na carcaça (P=0,06; 0,10 e 0,05 respectivamente) nos grupos tratados. Houve ausência de Salmonella spp. em todas as coletas realizadas. Concluiu-se que a suplementação reduziu a excreção fecal e consequentemente, a contaminação da carcaça pela Escherichia coli, mesófilos e coliformes totais dos animais confinados, sendo uma medida sanitária benéfica e livre de resíduos para melhorar a qualidade microbiológica da carne.UEL2023-02-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionExperimento controladoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4503110.5433/1679-0359.2023v44n1p123Semina: Ciências Agrárias; Vol. 44 No. 1 (2023); 123-134Semina: Ciências Agrárias; v. 44 n. 1 (2023); 123-1341679-03591676-546Xreponame:Semina.
