摘  要：
试验以血鹦鹉为研究对象,采用单因子浓度梯度法。在基础饲料中分别添加0、1‰、2‰、3‰、4‰浓度的虾青素,每间隔7 d测定血鹦鹉体色、生长指标。投喂49 d后测定体内总抗氧化能力(T-AOC)、过氧化氢酶(CAT)、超氧化物歧化酶(SOD)、溶菌酶(LSZ)的活性含量,探究虾青素对血鹦鹉体色、生长、部分非特异性免疫指标的影响。结果表明,添加4‰水平的虾青素增色效果显著高于对照组(P<0.05),2‰和3‰虾青素添加量血鹦鹉生长效果较好。4‰虾青素水平组对机体总抗氧化能力(T-AOC)及过氧化氢酶(CAT)的活性作用效果相对较显著,投喂不同水平虾青素对血液和肝脏中超氧化物歧化酶(SOD)、鳃丝中溶菌酶的活性作用均不明显。因此,在一定范围内添加不同水平的虾青素对血鹦鹉体表增色有显著的作用,对部分非特异性免疫的作用效果相近,但有增益作用。

摘  要：
The single factor density gradient method was used in this study to evaluate the effects of astaxanthin on the body color, growth and several index of nonspecific immune of blood parrot. Blood parrot were fed on basal diet with 0‰,1‰,2‰,3‰,4‰ astaxanthin for 7 weeks. The body color and growth index were measured every 7 days. After 7 weeks, the activities of total antioxidant capacity(T-AOC), catalase(CAT), superoxide dismutase(SOD) and the activity of lysozyme(LSZ)were measured. The results showed that, the hyperchromic effect of 4 ‰ astaxanthin group on the blood parrot was significantly higher than the control group, the growth rate were higher in the 2‰ and 3‰ group. The activities of T-AOC and CAT in the 4 ‰ astaxanthin group were significantly higher, but there were insignificant different of SOD activity in the blood and liver and LSZ in the gill among all the treatment groups. Therefore, add different level of astaxantin in a certain range had significant effect to blood parrot body graces, but had similar effects on the nonspecific immune index.
