The present study was designed to investigate the dietary effects of ginger extract (Zingiber officinale) on common carp (Cyprinus carpio). Three hundred and sixty fish weighing 10.9 ± 0.17 g were randomly divided into four experimental treatments in triplicates. Four experimental diets were designed containing different inclusion levels of ginger extract as 0% (control), 0.1%, 0.2%, and 0.4% named T1, T2, T3, and T4, respectively, and fish were fed 3% of body weight daily for 60 days. Feed conversion ratio, weight gain, and specific growth rate parameters were measured higher in the groups fed with ginger extract compared to the control, especially in T3 (P < 0.05). Also, fish treated with ginger extract showed lower carcass moisture and lipid, but higher protein contents compared to the control. The results showed significant increase in the number of erythrocytes and leucocytes, as well as the level of hematocrit and hemoglobin in fish fed with supplemented diets. In addition, significant enhancement was observed in cases of serum parameters, including total protein, albumin, globulin, lysozyme, superoxide dismutase, catalase, and total immunoglobulins in T3 and T4 compared to the control. The lowest serum cortisol level was noticed in T3. Furthermore, the T3 group showed the highest activities of skin mucus lysozyme, alkaline phosphatase, and protease (P < 0.05). In conclusion, the present results demonstrated that Zingiber officinale extract at a 0.2% level can effectively improve the growth and health status of Common Carp (Cyprinus carpio).

生姜(姜)提取物会影响鲤鱼(Cyprinus carpio)的生长性能,身体成分,血液学,血清和粘膜免疫参数。

本研究旨在研究姜提取物(姜)对鲤鱼(Cyprinus carpio)的饮食作用。将360只重10.9±0.17 g的鱼随机分成四个实验处理一式三份。设计了四种实验饮食,分别含有不同含量的生姜提取物,分别为0%(对照),0.1%,0.2%和0.4%,分别命名为T1,T2,T3和T4,每天给鱼喂食3%的体重持续60天。与对照组相比,用生姜提取物喂养的组的饲料转化率,增重和特定生长率参数更高,尤其是在T3组(P <0.05)。此外,用生姜提取物处理的鱼与car鱼相比,moisture体水分和脂质更低,但蛋白质含量更高。结果表明,饲喂补充饲料的鱼的红细胞和白细胞数量以及血细胞比容和血红蛋白水平显着增加。另外,与对照相比,血清参数包括总蛋白,白蛋白,球蛋白,溶菌酶,超氧化物歧化酶,过氧化氢酶和总免疫球蛋白的血清参数显着增强。在T3中观察到最低的血清皮质醇水平。此外,T3组的皮肤粘液溶菌酶,碱性磷酸酶和蛋白酶的活性最高(P <0.05)。综上所述,目前的结果表明,0.2%的姜皮提取物可以有效改善鲤鱼的生长和健康状况。以及补充饮食喂养的鱼的血细胞比容和血红蛋白水平。另外,与对照相比,血清参数包括总蛋白,白蛋白,球蛋白,溶菌酶,超氧化物歧化酶,过氧化氢酶和总免疫球蛋白的血清参数显着增强。在T3中观察到最低的血清皮质醇水平。此外,T3组的皮肤粘液溶菌酶,碱性磷酸酶和蛋白酶的活性最高(P <0.05)。综上所述,目前的结果表明,0.2%的姜皮提取物可以有效改善鲤鱼的生长和健康状况。以及补充饮食喂养的鱼的血细胞比容和血红蛋白水平。另外,与对照相比,血清参数包括总蛋白,白蛋白,球蛋白,溶菌酶,超氧化物歧化酶,过氧化氢酶和总免疫球蛋白的血清参数显着增强。在T3中观察到最低的血清皮质醇水平。此外,T3组的皮肤粘液溶菌酶,碱性磷酸酶和蛋白酶的活性最高(P <0.05)。综上所述,目前的结果表明,0.2%的姜皮提取物可以有效改善鲤鱼的生长和健康状况。与对照相比,T3和T4中的超氧化物歧化酶,过氧化氢酶和总免疫球蛋白。在T3中观察到最低的血清皮质醇水平。此外,T3组的皮肤粘液溶菌酶,碱性磷酸酶和蛋白酶的活性最高(P <0.05)。综上所述,目前的结果表明,0.2%的姜皮提取物可以有效改善鲤鱼的生长和健康状况。与对照相比,T3和T4中的超氧化物歧化酶,过氧化氢酶和总免疫球蛋白。在T3中观察到最低的血清皮质醇水平。此外,T3组的皮肤粘液溶菌酶,碱性磷酸酶和蛋白酶的活性最高(P <0.05)。综上所述,目前的结果表明,0.2%的姜皮提取物可以有效改善鲤鱼的生长和健康状况。
