Resumo: The aim of this study was to evaluate the effects of different feeding frequencies on productive performance, hepatocytes integrity, frequency of muscle fibers distribution, enzymatic activity, and proximate composition of pacu juveniles (Piaractus mesopotamicus). One hundred and sixty fish were distributed in 20 tanks arranged in a recirculation system. The proposed managements of feed offer were the partition of the daily amounts into one, two, three or four times during 60 days. Feed consumption were higher in fish fed four times a day, whilst the hepatosomatic index was higher in fish fed once, but similar to fish that received food two or four times a day. As for plasmatic glucose levels, fish fed twice a day displayed an increase in this parameter. The livers of fish fed two or four times a day presented larger hepatocytes and cellular nuclei. Regarding the proximate composition of carcasses, fish that received one daily feeding presented higher ether extract. It was concluded that feeding frequency is a factor that promotes changes in P. mesopotamicus nutritional metabolism, thus the offer of feed four times a day could be recommended for this species in this life stage.

Se distribuyeron ciento sesenta peces en 20 tanques dispuestos en un sistema de recirculación. Las propuestas para gestionar el suministro de pienso consistieron en dividir las cantidades diarias en una, dos, tres o cuatro veces durante 60 días. El consumo de alimento fue mayor en los peces alimentados cuatro veces al día, mientras que el índice hepatosomático fue mayor en los peces alimentados una vez, pero similar a los peces que recibieron alimento dos o cuatro veces al día. En cuanto a los niveles de glucosa plasmática, los peces alimentados dos veces al día mostraron un aumento en este parámetro. Los hígados de los peces alimentados de dos a cuatro veces al día tenían hepatocitos y núcleos celulares más grandes. En cuanto a la composición centesimal de las canales, los peces que recibieron alimentación diaria mostraron un mayor extracto de éter. Se concluyó que la frecuencia de alimentación es un factor que promueve cambios en el metabolismo nutricional de P. mesopotamicus, por lo que se podría recomendar la oferta de alimento cuatro veces al día para esta especie en esta etapa de la vida.O objetivo deste estudo foi avaliar os efeitos de diferentes frequências de alimentação no desempenho produtivo, integridade dos hepatócitos, frequência de distribuição das fibras musculares, atividade enzimática e composição centesimal de juvenis de pacu (Piaractus mesopotamicus). Cento e sessenta peixes foram distribuídos em 20 tanques dispostos em sistema de recirculação. As propostas de manejo da oferta de ração consistiam na partição das quantidades diárias em uma, duas, três ou quatro vezes durante 60 dias. O consumo de ração foi maior nos peixes alimentados quatro vezes ao dia, enquanto o índice hepatossomático foi maior nos peixes alimentados uma vez, mas semelhante aos peixes que receberam ração duas ou quatro vezes ao dia. Quanto aos níveis de glicose plasmática, os peixes alimentados duas vezes ao dia apresentaram aumento desse parâmetro. Os fígados de peixes alimentados duas a quatro vezes ao dia apresentavam hepatócitos e núcleos celulares maiores. Em relação à composição centesimal das carcaças, os peixes que receberam uma alimentação diária apresentaram maior extrato etéreo. Concluiu-se que a frequência alimentar é um fator que promove alterações no metabolismo nutricional de P. mesopotamicus, portanto, a oferta de ração quatro vezes ao dia poderia ser recomendada para esta espécie nesta fase de vida.Research, Society and Development2021-04-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1397910.33448/rsd-v10i4.13979Research, Society and Development; Vol. 10 No. 4; e28710413979Research, Society and Development; Vol. 10 Núm. 4; e28710413979Research, Society and Development; v. 10 n. 4; e287104139792525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/13979/12555Copyright (c) 2021 Mariana Lins Rodrigues; Robson Araújo dos Santos; Rebeca Maria Sousa; Claucia Aparecida Honorato; Dacley Hertes Neu; Fábio Bittencourthttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRodrigues, Mariana Lins Santos, Robson Araújo dos Sousa, Rebeca Maria Honorato, Claucia Aparecida Neu, Dacley Hertes Bittencourt, Fábio2021-04-25T11:21:26Zoai:ojs.pkp.sfu.ca:article/13979Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:35:12.414817Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
