IntroductionThe present study investigates the effects of mushroom powder (MP) on growth parameters, haematological indices, innate immune response, and serum biochemical indices in beluga (Huso huso) juveniles.MethodsA total of 120 fish (45 ± 0.5 g) were stocked with 10 fish in each 300-L tank. Experimental diets were prepared by inclusion of 0, 0.5, 1.0, and 2.0% MP. At the end of the feeding trial haemato-immunological parameters as well growth performance were measured.ResultsThe growth parameters results revealed that body weight, specific growth rate (SGR), and body length increased significantly in the fish fed diets containing 1% and 2% MP (P<0.05). Haematological indices results indicated that none of the experimental diets showed significant effects on red blood cell count (RBC), hemoglobin, mean corpuscular volume (MCV), mean cell hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) (P >0.05). However, the haematocrit increased significantly in the fish fed diets containing 1% MP compared to the control (P<0.05). White blood cell count (WBC) in the fish fed 2% MP was significantly higher than that in the fish fed 0% and 0.5% MP (P<0.05). Furthermore, MP treatments caused no significant change in the activity of complement C3 (P >0.05), while C4 activity increased significantly in the fish fed 2% MP (P<0.05). Total immunoglobulin in 1% MP had no significant difference when compared with control (P >0.05). Albumin level was significantly higher in fish fed 2% MP compared to control (P<0.05).DiscussionIn conclusion, MP (2%) can be considered to improve growth parameters and immune indices in beluga juveniles.

日粮双孢蘑菇粉对白鲸 (Huso huso) 幼鱼生长性能、血液学指标和血清免疫反应的影响



简介本研究调查了蘑菇粉 (MP) 对白鲸 (Huso huso) 幼鱼生长参数、血液学指标、先天免疫反应和血清生化指标的影响。方法共放养 120 条鱼 (45 ± 0.5 g),每个 300 L 水箱中 10 条鱼。通过添加 0% 、 0.5% 、 1.0 和 2.0% MP 来制备实验饮食。在喂养试验结束时,测量血液免疫学参数以及生长性能。结果生长参数结果显示,饲喂 MP 含量为 1% 和 2% 的鱼的体重、比生长速率 (SGR) 和体长显著增加 (P<0.05)。血液学指标结果显示,实验饮食对红细胞计数 (RBC) 、血红蛋白、平均红细胞体积 (MCV)、平均细胞血红蛋白 (MCH) 和平均红细胞血红蛋白浓度 (MCHC) 均无显著影响 (P >0.05)。然而,与对照相比,饲喂含 1% MP 的鱼的饮食中的血细胞比容显着增加 (P<0.05)。饲喂 2% MP 的鱼的白细胞计数 (WBC) 显著高于饲喂 0% 和 0.5% MP 的鱼 (P<0.05)。此外,MP 处理未引起补体 C3 活性的显著变化 (P >0.05),而 C4 活性在饲喂 2% MP 的鱼中显著增加 (P<0.05)。与对照组相比,1% MP 中的总免疫球蛋白无显著差异 (P >0.05)。与对照相比,饲喂 2% MP 的鱼的白蛋白水平显著升高 (P<0.05)。讨论总之,MP (2%) 可以被认为可以改善白鲸幼鱼的生长参数和免疫指数。
