Resumo: The objective of this work was to evaluate the effects of lactulose (0.03 mL kg-1) on the intestinal health and weight gain of turkeys subjected to the inoculation of Salmonella serovar (sv.) Enteritidis (SE). A total of 280 turkeys, with one day of age, were distributed in the following treatments: T1, negative control; T2, group that received only lactulose; T3, group subjected to the inoculation of approximately 7.0x105 CFU mL-1 SE; and T4, group subjected to the inoculation of approximately 7.0x105 CFU mL-1 SE and treated with lactulose. Poultry performance was evaluated weekly, and seven turkeys from each treatment were euthanized to collect duodenum and jejunum fragments for the histomorphometric analysis. A lower weight gain was observed in the group that received only the pathogen, and the best performance was observed in the lactulose-treated group. The histomorphometric analysis showed a higher villus:crypts ratio in the duodenum and jejunum samples of the negative control and of the group of turkeys at 7 and 21 days of age treated with the lactulose-supplemented diet. Lactulose allows of a better intestinal development of turkeys until 42 days of age, but it does not interfere with poultry performance.

Um total de 280 perus, com um dia de idade, foram distribuídos nos seguintes tratamentos: T1, controle negativo; T2, grupo que recebeu apenas lactulose; T3, grupo submetido à inoculação de aproximadamente 7,0x105 UFC mL-1 de SE; e T4, grupo submetido à inoculação de aproximadamente 7,0x105 UFC mL-1 de SE e tratado com lactulose. O desempenho das aves foi avaliado semanalmente, e sete perus por tratamento foram submetidos à eutanásia, para a coleta de fragmentos do duodeno e do jejuno para a análise histomorfométrica. Observou-se menor ganho de peso no grupo que recebeu apenas o patógeno, e o melhor desempenho, no grupo tratado com lactulose. A análise histomorfométrica mostrou maior relação vilos: criptas nas amostras de duodeno e jejuno do controle negativo, e dos grupos de perus, aos 7 e aos 21 dias de idade, tratados com dieta suplementada com lactulose. A lactulose proporciona melhor desenvolvimento intestinal de perus até os 42 dias de vida, mas não interfere no desempenho dessas aves.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes)Santana, Eliete SouzaAndrade, Maria AuxiliadoraSilveira Neto, Osvaldo José daJayme, Valéria de SáCamargo, José Neto Cassiano deBarnabé, Ana Caroline de Souza2020-12-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/26838Pesquisa Agropecuaria Brasileira; V.55, Jan./Dec., 2020: Publicação contínua em volume anual; e01708Pesquisa Agropecuária Brasileira; V.55, Jan./Dec., 2020: Publicação contínua em volume anual; e017081678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/26838/14814Direitos autorais 2020 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2022-05-18T18:26:38Zoai:ojs.seer.sct.embrapa.br:article/26838Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2022-05-18T18:26:38Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
