Abstract

This study evaluated the impacts of dietary Alpinia oxyphylla extract (AO) on growth, muscle composition, antioxidant status, immunity, and ammonia resistance of juvenile ivory shell (Babylonia areolata). Six experimental diets (AO1, AO2, AO3, AO4, AO5, and AO6) with varying AO levels (0, 1, 2, 4, 6, and 10 g/kg diet) were fed to the ivory shell for 8 weeks. The weight gain rate and specific growth rate were higher in AO3 and AO4 groups. Muscle crude protein content was significantly higher in AO4 and AO5 groups, while crude lipid content significantly decreased in AO4 group compared to the control group. Superoxide dismutase (SOD) activity was increased in AO-fed B. areolata, with the highest values in the AO3 group. Catalase (CAT) activity was significantly increased in AO3, AO4, AO5, and AO6 groups. Total antioxidant capacity (T-AOC) was significantly higher and malondialdehyde (MDA) content was significantly lower, in AO3 and AO4 groups compared to the control group. The highest acid phosphatase (ACP) value was recorded in AO3, AO4, and AO5 groups, while alkaline phosphatase (AKP) activity was significantly higher in AO4, AO5, and AO6 groups compared to the control group. AO significantly induced the expression of SOD, GST, CYP450, ACP, and CYC in hepatopancreas. After ammonia stress, B. areolata fed with 2–4 g/kg AO showed a higher survival rate compared to the control group. These results suggest that dietary AO supplementation at 2.26 g/kg AO improves growth, muscle composition, immunity, and ammonia resistance in B. areolata.

饲粮中添加木叶高寒提取物对乳白幼虾生长指标、肌肉成分、抗氧化状态、免疫和氨氮抗性的影响

本试验研究了饲粮中添加木叶高寒提取物（AO）对乳白幼虾生长、肌肉组成、抗氧化状态、免疫和氨氮抗性的影响。将不同AO水平（0、1、2、4、6和10 g/kg）的6种试验饲粮（AO1、AO2、AO3、AO4、AO5和AO6）饲喂于象壳8周。AO3和AO4组的增重率和特定生长率较高。AO4和AO5组肌肉粗蛋白质含量显著高于对照组，而AO4组肌肉粗脂肪含量显著低于对照组。超氧化物歧化酶（SOD）活性升高，以AO3组最高。AO3、AO4、AO5和AO6组过氧化氢酶（CAT）活性显著升高。AO3和AO4组总抗氧化能力（T-AOC）显著高于对照组，丙二醛（MDA）含量显著低于对照组。酸性磷酸酶（ACP）值以AO3、AO4和AO5组最高，碱性磷酸酶（AKP）活性以AO4、AO5和AO6组显著高于对照组。AO显著诱导肝胰腺SOD、GST、CYP450、ACP和CYC的表达。氨胁迫后，添加2 ~ 4 g/kg AO的乳状白僵菌存活率高于对照组。综上所述，饲粮中添加2.26 g/kg的AO可改善乳状白僵鱼的生长、肌肉组成、免疫力和抗氨能力。

期刊介绍： Aquaculture Reports will publish original research papers and reviews documenting outstanding science with a regional context and focus, answering the need for high quality information on novel species, systems and regions in emerging areas of aquaculture research and development, such as integrated multi-trophic aquaculture, urban aquaculture, ornamental, unfed aquaculture, offshore aquaculture and others. Papers having industry research as priority and encompassing product development research or current industry practice are encouraged.
