The aim of this research was to evaluate the influence of thyme and a mixture of thyme whit vitamin E on hematological profile, some biochemical indices and leukocyte reaction of Oreochromis niloticus species, reared in a semi-intensive aquaculture system. The experiment was made in replicate, during 31 days, and the experimental variants were: V1 – 1% thyme (Thymus vulgaris)/kg feed and V2 – 1% thyme + 500 mg vitamin E/kg feed. At the end of the experiment, in V2 variant, a significant increase (p<0.05) were registered in case of red blood cells count (RBCc), hemoglobin concentration (Hb), mean corpuscular hemoglobin concentration (MCHC), lysozyme activity, absolute number of leukocyte (lymphocytes, monocytes) and platelets. Also, in V2 variant, was obtained a significant decrease (p<0.05) in case of blood glucose concentration. In conclusion, we showed that the additivited diet of Nile tilapia, particularly, with a mixture of thyme and vitamin E (V2) had a synergistic influence on fish welfare status by improving the hematological profile, immune parameters (lysozyme activity, leukocyte reaction) and decrease of blood glucose concentration.
