Resumo: | To determine the requirements for total phosphorus in the diet of the pejerrey (Odontesthes bonariensis) and silver catfish (Rhamdia quelen) were formulated two purified diets (basal diet with low levels of total phosphorus) and two practical diets (with conventional ingredients used in diets of fish). The purified diet for juvenile pejerrey showed levels of total phosphorus concentrations of 0.09, 0.27, 0.57 and 0.83% for juvenile silver catfish and 0.04, 0.30, 0.47 and 0.70%. The basal practical diet showed level of 0.76% at total phosphorus, and the others supplemented with dicalcium phosphate resulted in levels of 0.90, 1.20, 1.97%.In all the experiments were evaluated for yield performance variables such as weight gain, length, specific growth rate and survival. At the end of the experiment was conducted analysis of body composition. In fish subjected to different levels of phosphorus in purified diets were determined the mineral composition of calcium, phosphorus, magnesium and potassium in the bones and scales. To juveniles pejerrey levels of 0.43% of total phosphorus result in better performance, however to maximize mineral deposition are required 0.63% of total phosphorus. The use of with practical diets at least 0.76% of phosphorus not needs supplementation with phosphate. With respect to juvenile silver catfish phosphorus levels resulting in better performance were 0.53 based purified diet the requirement of phosphorus for juvenile silver catfish is 0.53% for a good productive performance. Practical diets with at least 0.76% of total phosphorus do not need supplementation of phosphate, it does not improve the growth of juvenile silver catfish. Purified diet based on the requirement of phosphorus for juveniles of silver catfish is 0.53% for a good productive performance. Practical diets with at least 0.76% of total phosphorus do not need supplementation of phosphate, because it does not improve the growth of juvenile silver catfish. |

A dieta purificada para os juvenis de peixe-rei apresentou níveis de fósforo total nas concentrações de 0,09, 0,27, 0,57 e 0,83% e para juvenis de jundiá 0,04, 0,30, 0,47 e 0,70%. A dieta prática apresentou nível de 0,76% de fósforo total, sendo as demais suplementadas com fosfato bicálcico resultando em níveis de 0,90, 1,20, 1,97%. Em todos os experimentos foram avaliados as variáveis de desempenho produtivo como ganho de peso, comprimento total, taxa de crescimento específico e sobrevivência. Ao término do período experimental realizou-se análise de composição química corporal. Nos peixes submetidos a diferentes níveis de fósforo em dietas semi-purificadas foi determinada a composição mineral de cálcio, fósforo, magnésio e potássio nos ossos e escamas. Para os juvenis de peixe-rei níveis de 0,43% de fósforo total resultaram em melhor desempenho produtivo, entretanto para maximizar a deposição mineral foram requeridos 0,63% de fósforo total. A utilização de uma dieta prática com no mínimo 0,76% de fósforo total não necessita suplementação com fosfato. Baseado na dieta purificada a exigência de fósforo total para juvenis de jundiá foi de 0,53% para um bom desempenho produtivo. Dietas práticas com pelo menos 0,76% de fósforo total não necessitam de suplementação de fosfato, pois não melhoraram o crescimento de juvenis de jundiá.application/pdfporUniversidade Federal de PelotasPrograma de Pós-Graduação em ZootecniaUFPelBRFaculdade de Agronomia Eliseu MacielMineralOssosCrescimentoAmbientalMineralBonesGrowthEnvironmentalCNPQ::CIENCIAS AGRARIAS::ZOOTECNIAExigências alimentares de fósforo em duas espécies nativas: peixe-rei (Odontesthes bonariensis) e jundiá (Rhamdia quelen)Phosphorus feed requirements in two native species: pejerrey (Odontesthes bonariensis) and silver catfish (Rhamdia quelen)info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesishttp://lattes.cnpq.br/5336629012294985Pouey, Juvêncio Luis Osório FernandesRocha, Cleber Bastosinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFPel - Guaiacainstname:Universidade Federal de Pelotas (UFPEL)instacron:UFPELORIGINALtese_cleber_bastos_rocha.pdfapplication/pdf1560103http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2614/1/tese_cleber_bastos_rocha.pdffabf749e97922e7d380da17b66a26b52MD51open accessTEXTtese_cleber_bastos_rocha.pdf.txttese_cleber_bastos_rocha.pdf.txtExtracted Texttext/plain94275http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2614/2/tese_cleber_bastos_rocha.pdf.txtb05a20a742045443d96f3339c8524726MD52open accessTHUMBNAILtese_cleber_bastos_rocha.pdf.jpgtese_cleber_bastos_rocha.pdf.jpgGenerated Thumbnailimage/jpeg1363http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2614/3/tese_cleber_bastos_rocha.pdf.jpg86d6332ff807c60929f6d16a893d57c7MD53open access123456789/26142023-07-18 08:30:57.052open accessoai:guaiaca.ufpel.edu.br:123456789/2614Repositório InstitucionalPUBhttp://repositorio.ufpel.edu.br/oai/requestrippel@ufpel.edu.br || repositorio@ufpel.edu.br || aline.batista@ufpel.edu.bropendoar:2023-07-18T11:30:57Repositório Institucional da UFPel - Guaiaca - Universidade Federal de Pelotas (UFPEL)false |
