Resumo: | The aim of this study was to determine the requirement of digestible phosphorus in diets for juvenile tambaqui (Colossoma macropomum). 300 juveniles (26.4 ± 0.68 g) were used in a completely randomized design, consisting of six treatments with five replicates and 10 fish per experimental unit. The treatments consisted of six isoprotein, isonitrogenous, and isocalcium rations, with different levels of digestible phosphorus: 0.27; 0.46; 0.67; 0.91; 1.04; and 1.14%. The fish were kept in 30 polyethylene tanks (500 L) with a closed water circulation system and fed six meals per day for 49 days. Parameters of performance and feed efficiency, daily protein, and fat, ash, and phosphorus deposition rates were evaluated. The elevation of digestible phosphorus provided a quadratic increase in feed consumption to a level of 0.92%, linear increase in the consumption of digestible phosphorus, and quadratic reduction in the efficiency of digestible phosphorus for weight gain. The linear response plateau model was the best fit for weight gain and specific growth rate, estimated at 0.55% and 0.56% digestible phosphorus, respectively. The feed conversion and protein efficiency for weight gain improved quadratically up to an estimated level of 0.84% of digestible phosphorus. Body fat deposition improved quadratically up to an estimated level of 0.90% of digestible phosphorus. The linear response plateau model was the best fit for body deposition of protein, ash, and phosphorus, estimated at 0.55%, 0.46%, and 0.59% of digestible phosphorus, respectively. To optimize weight gain, the recommended level of digestible phosphorus in diets for juvenile tambaqui is 0.55%, which corresponds to an estimated level of 0.87% of total phosphorus. |

Utilizou-se 300 juvenis (26,4±0,68 g) em delineamento inteiramente casualizado, composto por seis tratamentos, cinco repetições e dez peixes por parcela. Os tratamentos constituíram-se de seis rações isoproteicas, isoenergéticas e isocálcicas, com diferentes níveis de fósforo digestível (0,27; 0,46; 0,67; 0,91; 1,04; e 1,14%). Os peixes foram mantidos em 30 caixas de polietileno de 500 L em sistema fechado de circulação de água e alimentados em seis refeições diárias durante 49 dias. Avaliaram-se parâmetros de desempenho e eficiência alimentar, taxas de deposição diária de proteína, gordura, cinzas e fósforo corporais. A elevação dos níveis de fósforo digestível proporcionou aumento de forma quadrática no consumo de ração até o nível de 0,92%, aumento linear no consumo de fósforo digestível, e redução de forma quadrática na eficiência de fósforo digestível para o ganho de peso dos peixes. Para o ganho de peso e taxa de crescimento específico dos peixes, o modelo Linear Response Plateau foi o que melhor se ajustou aos dados, estimando em 0,55% e 0,56% o nível de fósforo digestível a partir dos quais ocorreram os platôs. A conversão alimentar e a eficiência proteica para o ganho de peso melhoraram de forma quadrática até o nível estimado de 0,84% de fósforo digestível, respectivamente. A deposição gordura corporal de forma quadrática até o nível estimado de 0,90% de fósforo digestível. Para as deposições corporais de proteína e cinzas e fósforo, o modelo Linear Response Plateau foi o que melhor se ajustou aos dados, estimando em 0,55%, 0,46%, 0,59% o nível de fósforo digestível a partir dos quais ocorreram os respectivos platôs. Concluiu-se que a recomendação dos níveis de fósforo digestível em rações para juvenis de tambaqui é de 0,55%, por otimizar o ganho de peso, que corresponde ao nível estimado de 0,87% de fósforo total.UEL2018-08-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3110310.5433/1679-0359.2018v39n5p2145Semina: Ciências Agrárias; Vol. 39 No. 5 (2018); 2145-2156Semina: Ciências Agrárias; v. 39 n. 5 (2018); 2145-21561679-03591676-546Xreponame:Semina.
