Resumo: Commercial diets for fish culture are supplemented with an inorganic zinc sources. Zinc oxide (ZnO) is the most utilized Zn supplementation in Brazil. However, organic metal complexes may increase mineral absorption in the digestive tract. Based on this knowledge, the effects of a amino acid zinc complex (Zn-AA) upon growth performance and carcass composition of Nile tilapia, Oreochromis niloticus L., fingerlings, were compared to the ones observed for ZnO. Isoproteic and isoenergetic soybean meal/corn-based diets were offered to fish for 75 days, supplemented with 30, 90, 150 or 210mg Zn/kg, from ZnO or Zn-AA. Fish (1.79 ± 0.10g) were allocated in thirty six 250-L tanks, and fed ad libitum four times a day. Fish fed with ZnO-supplemented diets, regardless of the supplementation level, showed a significantly higher weight gain than the animals fed with Zn-AA-supplemented diets (P<0.05). Besides, food conversion and protein efficiency ratio of fish fed with ZnO were significantly better than the verified for fish fed with Zn-AA-supplemented diets. The proximal composition of fish carcasses was statistically similar (P>0.05) for different experimental treatments. The experiment showed that Zn-AA supplementation produced worse fish growth performance than ZnO.

Complexos organometálicos, contudo, podem aumentar a absorção do mineral no trato digestório. Nesse sentido, comparou-se os efeitos de um complexo zinco-aminoácido (Zn-AA) sobre o desempenho produtivo e a composição da carcaça de alevinos de tilápia do Nilo, Oreochromis niloticus L., em relação ao verificado com o uso do ZnO. Dietas experimentais, isoprotéicas e isocalóricas, à base de farelo de soja e fubá de milho, foram fornecidas aos peixes durante 75 dias, sendo suplementadas com 30, 90, 150 ou 210mg Zn/kg, a partir do ZnO ou do Zn-AA. Os peixes (1,79 ± 0,10g) foram distribuídos em 36 caixas de água de 250L, sendo alimentados ad libitum, quatro vezes ao dia. Ao final do período experimental, os peixes alimentados com as dietas suplementadas com ZnO, independentemente do nível de suplementação, apresentaram ganho em peso significativamente maior que os animais arraçoados com as dietas contendo Zn-AA (P<0,05). Além disso, a conversão alimentar e a taxa de eficiência protéica dos animais que receberam as dietas com ZnO foram significativamente melhores que para os peixes alimentados com as dietas suplementadas com Zn-AA. A composição bromatológica das carcaças dos peixes, nos diferentes tratamentos experimentais, foi estatisticamente similar entre si (P>0,05). Os resultados do presente trabalho permitem concluir que, em relação ao observado com o uso do ZnO, o Zn-AA acarretou pior desempenho produtivo nos peixes estudados.Editora da Universidade Estadual de Maringá2008-04-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/171610.4025/actascianimsci.v26i4.1716Acta Scientiarum.
