Diet supplemented with nettle Urtica dioica and tarragon Artemisia dracunculus leaf powder on fingerling rainbow trout Oncorhynchus mykiss was assessed. Fish of initial body weight 7.41 ± 0.16 g, were distributed in six groups, three replications, and were fed 8 weeks. 0 (control), 10 nettle (N1), 30 nettle (N3), 10 tarragon (T1), 30 tarragon (T3) and 10 nettle +10 tarragon g/kg (N1+T1) diet. The N3 improved FBW, WG, WG% and SGR significantly (p ≤ 0.05). N3 increased body protein, ash and decreased body fat significantly (p ≤ 0.05). The highest haematocrit was observed in T3 significantly (p ≤ 0.05). The highest WBC in T3, and RBC and Hb in N1+T1 were observed (p ≤ 0.05). N1 and N1+T1 showed the highest MCV (p ≤ 0.05). N1, T1 and N1+T1 showed the highest MCH (p ≤ 0.05). The highest MCHC was observed in T1 significantly (p ≤ 0.05). N3, T3 and N1+T1 demonstrated the highest albumin levels (p ≤ 0.05). The T1 increased serum lysozyme activity compared to control (p ≤ 0.05). The highest serum total immunoglobulin and total protein in N3 were observed (p ≤ 0.05). The results showed beneficial effects of N3, T3 and N1+T1 on growth performance, body proximate composition and blood parameters.

以荨麻和龙蒿为辅的日粮饲喂的虹鳟 Onchorhynchus mykiss 鱼种的生长、身体近似组成和选定的血液参数

饮食补充有荨麻异株荨麻和龙蒿龙蒿叶粉末上鱼种虹鳟鱼虹鳟进行了评估。初始体重 7.41 ± 0.16 g 的鱼被分成 6 组，3 次重复，喂食 8 周。0 (对照)、10 荨麻 (N1)、30 荨麻 (N3)、10 龙蒿 (T1)、30 龙蒿 (T3) 和 10 荨麻 +10 龙蒿 g/kg (N1+T1) 饮食。N3 显着改善了 FBW、WG、WG% 和 SGR（p  ≤ 0.05）。N3 显着增加体蛋白、灰分和减少体脂肪（p  ≤ 0.05）。在 T3 中观察到最高的血细胞比容 ( p  ≤ 0.05)。T3 期 WBC 最高，N1+T1 期观察到 RBC 和 Hb（p ≤ 0.05)。N1 和 N1+T1 显示出最高的 MCV ( p  ≤ 0.05)。N1、T1 和 N1+T1 显示最高 MCH ( p  ≤ 0.05)。在 T1 中观察到最高的 MCHC（p  ≤ 0.05）。N3、T3 和 N1+T1 显示出最高的白蛋白水平 ( p  ≤ 0.05)。与对照相比，T1 增加了血清溶菌酶活性（p  ≤ 0.05）。最高血清总免疫球蛋白和总蛋白在N3中观察到（p  ≤0.05）。结果显示 N3、T3 和 N1+T1 对生长性能、身体近似成分和血液参数的有益影响。
