| 摘 要： | 以初始体重(33.90±0.11)g的福瑞鲤(FFRC Strain Common Carp,Cyprinus carpio)为研究对象,在基础日粮中分别添加0(对照组)、25、50和100 mg/kg低聚壳聚糖,于室内可控温循环水养殖系统中进行35 d的实验,研究了低聚壳聚糖对福瑞鲤生长、非特异性免疫及抗氧化指标的影响。结果表明,与对照组相比,低聚壳聚糖对福瑞鲤生长性能、肌肉成分无显著影响(P0.05);各实验组血浆碱性磷酸酶活力显著提高(P0.01);各实验组血浆总铁结合力水平、补体C3和C4含量有一定升高(P0.05);25 mg/kg实验组脾脏NO水平极显著提高(P0.01);50(P0.05)和100mg/kg(P0.01)实验组脾脏髓过氧化物酶活力均有显著提高;50mg/kg实验组血浆超氧化物歧化酶活力显著升高且丙二醛水平显著降低(P0.05)。研究表明,饲料中添加适量的低聚壳聚糖对福瑞鲤的非特异性免疫和抗氧化功能有明显的增强作用。实验条件下,低聚壳聚糖添加量为50 mg/kg较适宜。

| Abstract: | This study was conducted to investigate the effects of chitosan-oligosaccharide on the growth performance, nonspecific immunity and antioxidant parameters of FFRC Strain Common Carp (Cyprinus carpio). The fish (mean initial weight : 33.90 ± 0.11 g) were randomly divided into 4 groups with 5 replicates per group and 15 fish per replicate. The fish were fed with either basal diet (control group) or basal diet supplemented 25, 50 and 100 mg/kg chitosan-oligosaccharide for 35 d, respectively. The results showed that dietary supplementation of chitosan-oligosaccharide did not significantly affect the growth performance and muscle composition of fish when compared with the control group (P>0.05). As expected, dietary chitosan-oligosaccharide supplementation significantly enhanced the activities of plasma alkaline phosphatase (AKP). The similar effects were also observed for the concentrations of plasma complement 3 (C3) and complement 4 (C4) as well as the content of total iron binding capacity (TIBC) in plasma (P>0.05). In addition, dietary chitosan-oligosaccharide supplementation at 25 mg/kg also significantly enhanced the content of nitric oxide (NO) in spleen. The activity of myeloperoxidase (MPO) in spleen was promoted in fish fed chitosan-oligosaccharide at 50 (P<0.05) and 100 mg/kg (P<0.01). Dietary 50 mg/kg chitosan-oligosaccharide supplementation significantly increased superoxide dismutase (SOD) level and decreased the maleic dialdehyde (MDA) content in plasma (P<0.05). Based on the results measured above, it was indicated that chitosan-oligosaccharide could effectively improve nonspecific immunity and antioxidant parameters of FFRC Strain Common Carp (Cyprinus carpio) and the optimum level of 50 mg/kg exerted the best effects on FFRC Strain Common Carp in the present study. |
