Resumo: | The objective of this study was to determine the crude protein requirements for juvenile jundiara fish, a hybrid of Pseudoplatystoma fasciatum X Leiarius marmoratus. A total of 240 juveniles of the hybrid, with an initial mean weight of 8.4 ± 1.41 g, were distributed in 15 fiberglass tanks (170 L) in a closed water recirculation and constant aeration system, with a density of 16 fish/tank. The experimental design was completely randomized with five treatments and three replications. The treatments consisted of diets with 32, 34, 36, 38 and 40% crude protein. Seventy days into the experiment the final fish weight and feed intake were measured. Two specimens from each experimental unit were collected for evaluation of carcass chemical composition, nutritional efficiency and blood parameters. The increase in crude protein content promoted the significant, increasing linear effect for mean weight gain, mean feed intake and specific growth rate, and decreasing effect for feed conversion. Significant differences were also observed in carcass chemical composition, nutritional efficiency, total plasma protein, glucose, cholesterol, triglycerides and lipase enzymatic activity. Thus, the increase in crude protein levels of up to 40% in jundiara diets promotes improvement in the productive performance of juvenile jundiara. |

El delineamiento experimental fue enteramente demandado, con cinco tratamientos y tres repeticiones. Los tratamientos residen en la inclusión de 32, 34, 36, 38 e 40% de proteína bruta. Después de 70 días de experimento, el peso final y la ingestión de ración de los peces fueron medidos. Dos ejemplares de cada unidad experimental fueron colectados para evaluación de la composición química de los residuos, eficiencia nutricional y parámetros sanguíneos. El aumento de los contenidos de proteína bruta promovió el efecto significativo efecto linear creciente para el gano de peso medio, consumo medio de la ración y índice de crecimiento específico, y decreciente a la conversión alimentar. También fueron evidenciadas diferencias significativas en la composición química de los residuos del pez, eficiencia nutricional, proteína plasmática total, glucosa, colesterol, triglicéridos y actividad enzimática de la lipasa. Con eso, el aumento de los niveles de proteína bruta hasta 40% en las dietas para el jundiara promueve una mejora en el desempeño productivo de los juveniles de jundiara.Objetivou-se determinar a exigência de proteína bruta para juvenis de jundiara, híbrido de Pseudoplatystoma fasciatum X Leiarius marmoratus. Foram utilizados 240 juvenis do híbrido, peso médio inicial de 8,4 ± 1,41 g, distribuídos em 15 tanques de fibra de vidro (170 L), em sistema fechado de recirculação de água e aeração constante, com densidade de 16 peixes por tanque. O delineamento experimental foi inteiramente casualizado, com cinco tratamentos e três repetições. Os tratamentos consistiram de dietas com 32, 34, 36, 38 e 40% de proteína bruta. Após 70 dias de experimento foram mensurados o peso final dos peixes e o consumo de ração. Dois exemplares de cada unidade experimental foram coletados para a avaliação da composição química da carcaça, eficiência nutricional e avaliação dos parâmetros sanguíneos. O aumento dos teores de proteína bruta promoveu o efeito significativo linear crescente para ganho de peso médio, consumo médio de ração e taxa de crescimento específico, e decrescente para conversão alimentar. Também foram evidenciadas diferenças significativas na composição química da carcaça, eficiência nutricional, proteína plasmática total, glicose, colesterol, triglicerídeos e atividade enzimática da lipase. Com isso, a elevação nos teores de proteína bruta de até 40% nas dietas para o jundiara promove melhoria no desempenho produtivo dos juvenis de jundiara.Research, Society and Development2020-08-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/686610.33448/rsd-v9i8.6866Research, Society and Development; Vol. 9 No. 8; e978986866Research, Society and Development; Vol. 9 Núm. 8; e978986866Research, Society and Development; v. 9 n. 8; e9789868662525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/6866/6090Copyright (c) 2020 Rafael Pereira Barros, Joaldo Rocha Luz, Ana Ana Paula de Souza Ramos, Deise Silva Costa, Luís Gustavo Tavares Bragahttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBarros, Rafael PereiraLuz, Joaldo RochaRamos, Ana Paula de SouzaCosta, Deise SilvaBraga, Luís Gustavo Tavares2020-08-20T18:00:17Zoai:ojs.pkp.sfu.ca:article/6866Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:29:49.518226Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
