摘  要：
本试验旨在研究饲喂丙氨酰-谷氨酰胺(Ala-Gln)对哲罗鱼(Hucho taimen)仔鱼生长和抗氧化能力的影响。试验分6个组,每组3个重复,每重复1 000尾鱼。各组饵料分别在基础饵料基础上添加0(对照组)、0.125%、0.250%、0.500%、0.750%和1.000%的Ala-Gln。试验共进行8周。结果表明:与对照组相比,0.125%组对哲罗鱼仔鱼的生长未产生显著影响(P>0.05);0.500%～1.000%组显著(P<0.05)或极显著(P<0.01)提高增重率和特定生长率;当添加量大于0.125%时,成活率显著(P<0.05)或极显著(P<0.01)提高;当添加量大于0.500%时,鱼体组织匀浆液中谷氨酰胺(Gln)含量显著升高(P<0.05);0.750%和1.000%组鱼体组织匀浆液中谷氨酸(Glu)含量显著提高(P<0.05);0.500%和0.750%组Na~+,K~+-ATPase活性显著升高(P<0.05);各添加组SOD活性显著提高(P<0.05),MDA含量显著(P<0.05)或极显著降低(P<0.01);氨基酸含量无显著变化(P>0.05)。由此可知,添加Ala-Gln可提高哲罗鱼仔鱼的生长性能和抗氧化能力,适宜的添加水平为0.750%。

摘  要：
This experiment was conducted to study the effects of alanyl-glutamine(Ala-Gin) on growth and antioxidant capacity of Hucho taimen larva.Six experimental diets containing different level of Ala-Gin(with the levels of 0,0.125%, 0.250%,0.500%,0.750%and 1.000%,respectively) were randomly assigned to 6 groups(with 3 replicates and 1 000 fish in each replicate) for 8 weeks.The results showed as follows:compared with the control group,the growth performance was not influenced by adding 0.125%Ala-Gin(P>0.05);weight gain rate(WGR) and specific growth rate(SGR) were increased significantly by adding 0.500%～1.000%Ala-Gin(P<0.05 or P<0.01) and survival rate was increased significantly by adding more than 0.125%Ala-Gin(P<0.05 or P<0.01);glutamine of fish body tissue fluid was increased by adding more than 0.500%Ala-Gin(P<0.05) and glutamic acid content was increased significantly by adding 0.750%and 1.000%Ala-Gin(P<0.05);Na~+,K~+-ATPase activity were increased by adding 0.500%and 0.750%Ala-Gin(P<0.05);superoxide dismutase(SOD) was increased(P<0.05) and malondialdehyde(MDA) was decreased significantly (P<0.05 or P<0.01),but amino acid content wasn't influenced by adding Ala-Gin(P>0.05).It was concluded that the growth performance and antioxidant capacity of Hucho taimen larva could be improved by adding Ala-Gin,and the appro- priate adding level of Ala-Gin was 0.750%.
