摘  要：
研究旨在观察生物饲料(biological feed)对罗氏沼虾(Macrobrachium rosenbergii)生长、消化酶和免疫酶活性的影响。选用平均体重(0.02±0.01)g的罗氏沼虾28 800尾作为试验对象,随机分成4组,每组设3个重复,每个重复2 400尾虾。分别投喂100%基础饲料(A组)、90%基础饲料+10%生物饲料(B组)、80%基础饲料+20%生物饲料(C组)、70%基础饲料+30%生物饲料(D组),饲养周期为42 d。结果表明:与A组比较,C、D组罗氏沼虾增重率差异显著(P<0.05),各组罗氏沼虾的增长率、特定生长率、饲料系数、存活率、肌肉营养指标和氨基酸含量无显著差异(P>0.05);B、C、D组罗氏沼虾胰蛋白酶的活性极显著提高(P<0.01),C、D组罗氏沼虾淀粉酶、纤维素酶和超氧化物歧化酶的活性显著提高(P<0.05),C组罗氏沼虾谷草转氨酶的活性显著提高(P<0.05);各组罗氏沼虾脂肪酶、过氧化氢酶、碱性磷酸酶、酸性磷酸酶和谷丙转氨酶的活性无显著差异(P>0.05)。结果提示,基础饲料中添加生物饲料能显著提高罗氏沼虾的增重率,增强胰蛋白酶、淀粉酶、纤维素酶、超氧化物歧化酶和谷草转氨酶的活性。

摘  要：
This experiment was conducted tostudy the effect of biological feed on growth, di-gestive enzyme and immune enzyme activities ingiant freshwater prawn Macrobrachium roseber-gii. In the study, the 28 880 giant freshwaterprawn with an average body weight of(0.02 ±0.01) g were randomly divided into 4 groups with 3 replicates per group and 2 400 shrimp per replicate. The giant freshwater prawn was fed 100%basic diet in group A, 90% basic diet with 10% biological feed in group B, 80% basic diet with 20%biological feed in group C, and 70% basic diet with 30% biological feed in group D for 42 days. Theresults showed as follows: the weight gain of giant freshwater prawn was significantly raised in groupsC and D(P<0.05). All groups had no significant effects on growth gain, specific rate, feed conversionratio, survival rate, nutritive composition of muscle and content of amino acid(P>0.05). The trypsin ac-tivity of giant freshwater prawn was remarkably improved in groups B, C and D(P<0.01), the amylase,cellulose and superoxide dismutase activity of giant freshwater prawn improved notably in groups Cand D(P<0.05), the glutamic-oxalacetic transaminease activity of giant freshwater prawn was remark-ably improved in group C(P<0.05). All groups had no significant effects on lipase, catalase, alkalinephosphatase, acid phosphatase, glutamic-pyruvic transaminase activity(P>0.05). These results indicat-ed that biological feed could improve weight gain, amylase, cellulose, superoxide dismutase and glutam-ic-oxalacetic transaminease activity of giant freshwater prawn.
