| Resumo: |
Pacu (Piaractus mesopotamicus Holmberg, 1887) is a valued Brazilian fish species for aquaculture. This is highly susceptible to disease, and feed supplementations for pacu can be a very important strategy to prevent disease incidence in fish farms. The aim of this study was to evaluate a strategic supplementation for pacu. Juvenile pacu (10.5 ± 1.2 g) were fed diets containing three levels of vitamins C and/or E (0, 250, and 500 mg vitamin kg-1 diet). Fish were fed diets without supplementation for two months prior to the experiment. After that period, experimental feeding was initiated for two months. Growth and hematological evaluations were made on the thirtieth and sixtieth days of feeding. Pacu fed diet without supplementation of vitamins C and E during 120 days did not show clear typical signs of deficiency. Fish fed diet vitamins C and E free increased feed intake, but no improvement on growth performance was detected. Vitamin E proved essential for erythrocyte protection, so that the higher the level of this vitamin in diet, the smaller the number of erythroblasts. Supplementation with 500 mg of vitamin C and 250 mg of vitamin E for 60 days increased the production of monocytes, thrombocytes and special granulocytic cells in pacu.
