The effect of vitamins E, C and selenium as stimulants of the immune system on blood factors, growth and immunity of Asian cates (Lates calcarifer)

 This study was performed to evaluate the effect of immune system stimulants (vitamins E, C and selenium) on biochemical and immunity indices of Late calcarifer. For this purpose, two treatments were selected. Treatment 1 or control group was fed with food without immune stimulant and treatment 2 with diet containing vitamins E, C and selenium at 2% of the biomass weight. Finally, growth efficiency indices were compared in two treatments. Results showed final weight of the control and treatment groups was 761.33 ± 35.8 g and 850.00 ± 5.77 g, respectively. The specific growth rate of the control and treatment groups was 1.3 ± 0.02 and 1.35 ± 0.01 but the feed conversion ratio did not show a significant difference. Hemoglobin and erythrocytes showed a significant increase compared to the control in treatments containing immune stimulants and supplementation (p < 0.05). White blood cells ranged from 41417 ± 2964.84 in the treatment to 42500 ± 683.13 in the control treatment. The number of red blood cells in the control treatment was 2810000 ± 19.1763 and the recipient treatment was 3951667 ± 14588.84. Immune system stimulants including vitamins E, C and selenium can play a role in improving the growth, blood, biochemical and safety indices of farmed Late calcarifer.
