Resumo: The objective of this work was to evaluate the effects of dietary supplementation with fructooligosaccharides (FOS) on the performance, hematology, and immunology of pacu (Piaractus mesopotamicus) juveniles. A total of 0 (control), 2.0, and 4.0 g kg-1 of the probiotic were added to the fish diets. Fish (49.3±4.3 g) were allotted into 12 tanks of 60 L, in a completely randomized design (n=4). After 60 days, final weight, weight gain, specific growth rate, and feed conversion ratio were improved in the fish fed with the prebiotic, although feed intake was not affected by the treatments. The number of red blood cells was higher only in fish fed with 2.0 g kg-1 FOS. The opposite was observed for the hematimetric indices mean corpuscular volume and mean corpuscular hemoglobin, which decreased in fish fed with 2.0 g kg-1 FOS. The number of defense cells, such as leukocytes and thrombocytes, also increased in the prebiotic treatments. The evaluated immunological parameters were not influenced by prebiotic supplementation. Dietary FOS supplementation improved pacu growth and health.

Um total de 0 (controle), 2,0 e 4,0 g kg-1 do prebiótico foi adicionado à dieta dos peixes. Os peixes (49,3±4,3 g) foram alocados em 12 tanques de 60 L, em delineamento inteiramente casualizado (n=4). Após 60 dias, o peso final, o ganho de peso, a taxa de crescimento específico e a conversão alimentar melhorou nos peixes alimentados com o prebiótico, apesar do consumo de ração não ter sido afetado pelos tratamentos. O número de células vermelhas foi maior apenas nos peixes alimentados com 2,0 g kg-1 de FOS. O oposto foi observado para os índices hematimétricos de volume corpuscular médio e hemoglobina corpuscular média, os quais diminuíram nos peixes alimentados com 2,0 g kg-1 de FOS. O número de células de defesa, como leucócitos e trombócitos, também aumentou nos tratamentos com o prebiótico. Os parâmetros imunológicos avaliados não foram afetados pela suplementação do prebiótico. A suplementação dietética com FOS melhorou o crescimento e a saúde do pacu.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraConselho Nacional de Desenvolvimento Científico e TecnológicoCoordenação de Aperfeiçoamento de Pessoal de Nível SuperiorAnhambi Alimentação AnimalConselho Nacional de Desenvolvimento Científico e TecnológicoCoordenação de Aperfeiçoamento de Pessoal de Nível SuperiorAnhambi Alimentação AnimalDeon, Maday Priscila PivaBicudo, Álvaro José de AlmeidaSado, Ricardo Yuji2022-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/27056Pesquisa Agropecuaria Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e02460Pesquisa Agropecuária Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e024601678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/27056/14967Direitos autorais 2022 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2022-05-18T18:27:35Zoai:ojs.seer.sct.embrapa.br:article/27056Revistahttp://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
