Resumo: The study aims to evaluate the zootechnical performance of Nile tilapia fed with different commercial diets and relate such results with the centesimal composition and aminogram of the commercial feeds. There were five diets evaluated (A, B, C, D, and E) indicated for the tilapia growth-out phase (200 to 600g). Two hundred and twenty-five Nile tilapia (201.5 ± 4.7g) were distributed in 15 net tanks of 1m³ installed in ponds of 300m². After 98 days of rearing, the fish fed with diet E showed the best results, with final weight, fillet yield and feed conversion of up to 20% superior than other diets. Such a diet was the only one that reached values of the minimum requirement of tryptophan, besides showing an amino acid balance closer to the ideal protein for tilapia. The diet B showed crude protein values below the label (26%), as well as deficient in methionine, lysine and tryptophan, resulting in poor weight gain and feed conversion. The distance between the essential amino acid profile of diets and ideal profile for tilapia (DIP) showed a significant relation with the final weight and fillet yield. Therefore, it is concluded that the commercial diet with better amino acid balance, that is, a lower DPI shows the best performance.

Foram avaliadas cinco dietas (A, B, C, D e E) indicadas para o cultivo de tilápias na fase de terminação (200 a 600g). Duzentos e vinte cinco tilápias (201,5 ± 4,7 g) foram distribuídos em 15 tanques-rede de 1 m³ instalados em um viveiro de 300 m². Após 98 dias de cultivo, os peixes alimentados com a dieta E apresentaram os melhores resultados, com ganhos no peso final, rendimento de filé e conversão alimentar de até 20% superior em relação às outras dietas. Esta dieta foi a única que atingiu os valores de exigência mínima de triptofano, além de apresentar um balanço de aminoácidos mais próximo da proteína ideal para tilápia. A dieta B apresentou valores de proteína abaixo do rótulo (26%), além de deficiências em metionina, lisina e triptofano, resultando em pior ganho de peso e conversão alimentar. A distância do balanço de aminoácidos das dietas em relação a proteína ideal para tilápias (DPI) mostrou uma relação significativa com o peso final e o rendimento de filé. Sendo assim, conclui-se que a dieta comercial contendo um balanço de aminoácidos, ou seja, um menor DPI apresenta o melhor desempenho.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2019-10-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/48210.22491/RAC.2019.v32n3.10Agropecuária Catarinense Journal; Vol. 32 No. 3 (2019); 73-77Agropecuária Catarinense; v. 32 n. 3 (2019); 73-772525-60760103-0779reponame:Agropecuária Catarinense (Online)instname:Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)instacron:EPAGRIporhttps://publicacoes.epagri.sc.gov.br/rac/article/view/482/453Copyright (c) 2019 Revista Agropecuária Catarinenseinfo:eu-repo/semantics/openAccessSilva, Bruno CorrêaMassago, Haluko2020-04-28T21:40:08Zoai:ojs.publicacoes.epagri.sc.gov.br:article/482Revistahttps://publicacoes.epagri.sc.gov.br/RAC/indexPUBhttps://publicacoes.epagri.sc.gov.br/index.php/RAC/oaieditoriarac@epagri.sc.gov.br || lamperuch@epagri.sc.gov.br2525-60760103-0779opendoar:2020-04-28T21:40:08Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
