| This study was performed in order to investigate the importance of vitamin C and E in diet. In this study the effect of vitamin C and E supplement in diet on hematological and growth parameters of Caspian salmon have been investigated. Samples were Caspian Salmon juveniles (35±0.24 gr) which feed by extrude growing diet (EX-TG2) by different concentrations of vitamin C and Esimultaneusly. Different treatments (1 to 10) used in this study consisted of 100, 200, 300 mg/kg vitamin C by 20, 30, 40 g/kg vitamin E regularly. Last treatment feed with control diet. All fishes daily feed in 3% of their body weight 3 times a day. To investigate the interaction between vitamin C and E, this supplements used simultaneously in diet. Results shown that there is difference between treatments in growth parameters. Also results shown that treatments with higher vitamin C concentration had ore effect on growth and survival parameters significantly (p<0.05). Furthermore control treatment samples had lower growth and survival and higher FCR compare with treatment groups (p<0.05). Also there was significant difference between treatment groups in hematological parameters. WBC and Nutrophil and hematochrit were significantly higher in treatments with higher vitamin C concentrations (p<0.05). But there was not any differences in Lymphocytes and monosites between treatment groups. Total Immunoglobulin and lysosime was higher treatments with higher vitamin C and E (p<0.05). The conclusion of this study have shown that the best dos of vitamin C and E in diet was 300 and 30 mg/kg regularly. Also the results shown that there was an interaction between this two supplements in Caspian Salmon diet. |
