| In order to determine effect of various concentrations of Lavandula officinalis essence in ration on biochemistry of blood serum and mucosal immunity indices of Oncorhynchus mykiss with average weight of 10±2 g, an experiment was conducted in a completely randomized block design with four treatments in three replicates. The fishes were fed orally with concentrations of 0.5, 1 and 2 ml of L. officinalis essence per kg of food for 60 consecutive days. Treatment of without adding essence to diet also was considered as a control. According to the results, the amount of both enzymes of aspirate aminotransferase and alanine aminotransferase, triglyceride, cholesterol and glucose of serum blood of fishes fed with various concentrations of essence were significantly decreased (P<0.05). The least of these features was belong to concentration of 2 ml of essence in basic ration. But values of total protein and albumin of fishes under various concentrations had decreasing trend compared to the control (P<0.05). The maximum amount of these compositions were related to concentration of 2 ml L. officinalis essence. But lactat dehydrogenase enzyme was not affected by any of the essence concentrations. The results of mucus characteristics in fishes also showed that there were significant differences among concentrations in term of values of total protein, alkaline phosphatase and lysozyme (P<0.05). The most total protein and alkaline phosphatase were recorded in fishes fed with concentration of 2 ml essence about 374 mg/dl and 144 U/L respectively. Also the range of lysozyme enzyme changes was between 27 and 44 U/L. The lowest and the highest of this characteristic was related to control and 0.5 ml. Whereas, the difference of it with 1 ml concentration was not significant (P<0.05). Overall, the results showed that oral administration of different concentrations of Lavandula officinalis essence especially 2 ml per kg of diet had positive and significant effect on biochemistry of blood serum and mucosal immunity indices of Oncorhynchus mykiss. Therefore, use it as a dietary supplement in the basal diet is suggested. |
