摘    要:在中国对虾幼虾的基础饲料中分别添加不同剂量的维生素C(0、0.015%、0.030%、0.045%、0.060%)、β-葡聚糖(0、0.050%、0.075%、0.100%)和藻粉(0、2%、5%、7%),未添加组为对照组,探讨维生素C(Vc)、β-葡聚糖和藻粉对中国对虾幼虾成活率、相对增长(重)率及肌肉酸性磷酸酶(ACP)、过氧化氢酶(CAT)、超氧化物歧化酶(SOD)、溶菌酶(LSZ)活性的影响。室内网箱饲养40 d试验结果表明,饲料中添加Vc后,0.030%组幼虾相对增重率和CAT活性显著高于对照组(P<0.05),0.045%组ACP、CAT活性显著高于对照组(P<0.05),但Vc对SOD活性没有显著性影响,0.015%组LSZ活性极显著高于对照组(P<0.01);0.075%β-葡聚糖组的相对增重率、SOD活性显著高于对照组(P<0.05);添加7%藻粉能极显著提高相对增长(重)率(P<0.01),但ACP和LSZ活性呈极显著下降(P<0.01),添加5%藻粉能显著提高CAT活性(P<0.05)。

关 键 词:中国对虾  维生素C  β-葡聚糖  藻粉  免疫酶

Abstract:Penaeus chinensis juvenile were fed on basal diets supplemented with different levels Vc (0,0.015%,(0.030%),0.045%,0.060%), beta-glucan (0,0.050%,0.075%,0.100% )and algae powder(0,2%,5%,7% )for 40 days respectively.The shrimp fed on basal diet were regarded as control . Each group was treated with triplicate. Growth, survival rate and activities of acid phosphates(ACP), catalase (CAT), superoxidase(SOD) and lysozyme(LSZ) were measured.The relative body length gain and CAT activity of 0.030% Vc group were significantly higher than those of the control(P<0.05). The activities of ACP and CAT of 0.045% Vc group were enhanced(P<0.05). The activities of SOD were not affected by Vc supplement(P<0.05).The LSZ activities of 0.015% Vc group were significantly increased (P<0.01). The relative body length gain and SOD activity of (0.075%) beta-glucan group were significantly higher than those of the control(P<0.05). The relative body length and weight gain of 7% algae powder group were significantly increased(P<0.01),but the activity of ACP and LSZ of the group was decreased (P<0.05). The activities of CAT of 5% algae powder were enhanced(P<0.05).
Keywords:Penaeus chinensis  Vitamin C  beta-glucan  algae powder  immune enzyme
