Resumo: | The present study was carried out to evaluate the effect of the hypervitaminosis by supplementation of vitamin A in balanced ration, on the performance of Nile tilapia (Oreochromis niloticus) during sex reversal phase. The experiment was carried out during 30 days in a randomized experimental design with six treatments and five repetitions. Was considered an experimental unit an aquarium of 50L contends 70 post larvae. The first treatment was consisted by a ration where was added only commercial premix how a vitamin A (30 KUI) source. The others had been supplemented with 1.030, 2.030, 3.030, 4.030 e 5.030 KUI of vitamin A. At the end, the final average weight (FAW), the standard (SL) and total length (TL), the weight gain (WG), the biomass gain (BG), the apparent feed conversion (FA), the condition factor (CF) and the survival (SU) were assessed. The results of FAW, SL, WG and BG showed a negative linear effect (P<0,05) by the increase of the vitamin A in the ration. The hipervitaminosis of vitamin A above of 30 KUI damaged the post larvae Nile tilapia growth. |

O período experimental foi de 30 dias, com um delineamento inteiramente casualizado com seis tratamentos e cinco repetições. Foi considerado como unidade experimental um aquário de 50L contendo 70 pós-larvas. O primeiro tratamento constituiu de uma ração onde foi adicionado apenas o premix comercial como fonte de vitamina A (30 KUI). Os outros foram suplementados com 1.030, 2.030, 3.030, 4.030 e 5.030 KUI de vitamina A. Ao final do experimento os peixes foram avaliados quanto ao peso médio final (PMF), aos comprimentos total final (CT) e padrão final (CP), ao ganho de peso médio (GPM), ao ganho de biomassa (GB), a conversão alimentar aparente (CAA), ao fator de condição final (FC) e à sobrevivência (%). Os resultados de PMF, CP, GPM e GB mostraram um efeito linear negativo (P<0,05) em relação ao aumento dos níveis de vitamina A na ração. Conclui-se que a inclusão de vitamina A em níveis acima de 30 KUI prejudicam o crescimento das pós larvas de tilápia do Nilo.UEL2013-10-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Históricaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1212910.5433/1679-0359.2013v34n5p2465Semina: Ciências Agrárias; Vol. 34 No. 5 (2013); 2465-2472Semina: Ciências Agrárias; v. 34 n. 5 (2013); 2465-24721679-03591676-546Xreponame:Semina.
