Investigation of the effect of Coriander (Coriandrum savitum) on hematological and immune system of Rainbow Trout (Oncorhynchus mykiss)

This study includes the investigation of the effect of coriander (Coriandrum savitum) on haematological parameters and immune system of rainbow trout (Oncorhynchus mykiss). For this purpose, fish with an average weight of 40±25 g were used. Coriander was added to the feed as 0, 0.5, 1.0, 2.0 mg/g, and experimental groups were formed. Prepared feed was fed in the morning and evening and weighed as 2% of fish weight daily. Blood samples were taken from the fish on the 21st and 42nd days from the first feeding. After the feeding experiment (21st and 42nd days), hematological and immunological parameters were examined. As a result, adding up to 2% of coriander to the feed of Rainbow trout did not cause any problems in terms of fish growth. In the study, it was observed that there was no difference between the control group and the experimental group in terms of erythrocyte, leukocyte, hemoglobin, hematocrit, average erythrocyte volume, mean erythrocyte hemoglobin, mean erythrocyte hemoglobin concentration, total immunoglubin, lysozyme activity, nitroblue tetrazolium activity, protein values, whereas in terms of myeloperoxidase activity (P >0.05), a difference was observed between the control group and the experimental group (P <0.05).

本研究旨在探讨芫荽（Coriandrum savitum）对彩虹 trout（Oncorhynchus mykiss）血液学参数及免疫系统的影响。为此，平均体重为 40±25 克的鱼被用于实验。芫荽以 0、0.5、1.0、2.0 毫克/克的浓度添加到饲料中，形成实验组。饲料在早晨和傍晚投喂，每日重量为鱼体重的 2%。在第 21 天和 42 天首次投喂后，从鱼身上采集血液样本。在饲养实验（第 21 天和 42 天）结束后，对血液学和免疫学参数进行了检测。结果表明，将不超过 2% 的芫荽添加至 Rainbow trout 的饲料中，并未对鱼的生长造成任何问题。在研究中观察到，与对照组相比，实验组在红细胞、白细胞、血红蛋白、红细胞压积、平均红细胞体积、平均红细胞血红蛋白、平均红细胞血红蛋白浓度、总免疫球蛋白、溶菌酶活性、硝基蓝四氮唑活性、蛋白质值等方面均无显著差异（P >0.05），而在髓过氧化物酶活性方面，对照组与实验组之间存在显著差异（P <0.05）。
