【摘要】 本试验旨在通过在基础饲料中添加0.03%核苷酸、0.03%核苷酸+0.2%丙氨酸+0.2%甘氨酸、0.2%甘氨酸、0.2%柠檬酸+0.2%甘氨酸,研究对凡纳滨对虾生长、血清生化、肝胰腺消化酶以及抗氧化能力的影响。结果表明,饲料中添加0.03%核苷酸+0.2%丙氨酸+0.2%甘氨酸能显著提高凡纳滨对虾的增重率、特定生长率和日摄食率(P<0.05);饲料系数以添加0.2%甘氨酸最低(P<0.05);对虾的成活率不受添加这几种诱食剂的影响(P>0.05)。各组全虾粗蛋白和灰分含量差异不显著(P>0.05);添加0.2%甘氨酸全虾粗脂肪含量显著高于其它各组(P<0.05)。对虾血清中总蛋白、胆固醇、血糖、谷草转氨酶(AST)以及谷丙转氨酶(ALTc)的组间差异不显著(P>0.05)。对虾肝胰腺中脂肪酶活力在添加0.03%核苷酸最高,显著高于0.2%甘氨酸组;各组间淀粉酶活力差异不显著(P>0.05)。对虾血清中总抗氧化能力以添加0.2%柠檬酸+0.2%甘氨酸最高,与其它各处理差异显著(P<0.05)。更多还原

【Abstract】 The experiment was conduted to determine the effect of dietary 0.03%nucleotide,0.03% nucleotide+0.2%Ala+0.2%Gly,0.2%Gly and 0.2%citric acid+0.2%Gly on growth performance,body composition,serum biochemical composition,digestive enzyme and total-antioxidative activity of shrimp. The result indicated that weight gain,specific growth rate(SGR) and ingestion rate were significantly enhanced in group of 0.03%nucleotide+0.2%Ala+0.2%Gly(P<0.05);FCR was the lowest in group of 0.2%Gly(P<0.05);there was no significant difference of Survival rate(P>0.05).Crude protein and Ash content of whole body was not significiently different among the groups(P>0.05).Crude lipid content was the highest compared with other groups(P<0.05).Total protein,cholesterol,glucose, glutamine-oxaloacetatet ransaminase and glutamic-pyruvic transaminase in serum were not significantly different(P>0.05).The activity of Lipase reached highest in 0.03%nucleotide group and significantly higher compared with 0.2%Gly(P<0.05),howere,there was no significient difference in activity of AmylaseAmy among the groups(P>0.05).Total antioxidant avtivity reached highest in 0.2%citric acid+0.2%Gly(P<0.05).更多还原
