摘要
以史氏鲟Acipenser schrenckii为试验对象,在基础日粮中添加不同水平的紫丁香叶粉,研究紫丁香叶对史氏鲟生长性能和免疫指标的影响。试验共分9组(对照组、A^H组),A^H组试验饲料中紫丁香叶粉的质量分数分别为1%、2%、3%、4%、5%、6%、8%、10%,对照组饲料中不添加。饲养试验共进行56 d。结果表明:与对照组相比,A组、B组史氏鲟的增重率、特定生长率和饵料系数无显著差异(P>0.05);与对照组相比,除C组和F组外,其它各试验组鱼血浆中总蛋白和球蛋白含量均显著(P<0.05)或极显著下降(P<0.01);H组鱼血浆中白蛋白显著下降(P<0.05),谷丙转氨酶(ALT)显著升高(P<0.05),谷草转氨酶(AST)差异不显著(P>0.05);各试验组鱼血浆中C3、C4含量均比对照组有所降低,除C组和F组外,其余各组鱼血浆中C3、C4的含量均显著下降(P<0.05)。这说明,饲料中不同水平的紫丁香叶粉对史氏鲟生长和免疫具有不同程度的抑制作用。
Juvenile Amur sturgeon Acipenser schrenckii weighing 35 - 36 g was stocked into tanks of each 60 cm ×50 cm ×50 cm at 20 individuals per tank and fed the diets （42.18% of crude protein, and 12.20% crude fat） containing 0（control group）, 1% （group A）, 2% （group B）, 3% （group C）, 4% （group D）, 5% （group E）, 6% （group F）, 8% （group G） ,or 10% （group H） clove leaves for 56 days to evaluate the influence of clove leaves on growth performance and immunity in Amur sturgeon at water temperature of 21 -23 ℃. The results showed that there were no significant differences in weight gain rate, specific growth rate and feed conversion ratio between the control group, and group A and group B （ P 〉 0.05 ）. There were significantly （P 〈 0.05 ） or very significantly （ P 〈0.01 ）lower plasma protein and globulin levels in groups A, B, D, E, G, and H than those in the control group. The fish had significantly lower（ P 〈 0.05 ） plasma protein level and significantly higher （ P 〉 0.05 ） glutamate - pyruvate transaminase （GPT） in group H than the fish in the control group did. No significant difference （P 〉 0. 05） in glutamate -oxaloaeetate transaminase （GOT） was found in all groups. There were significantly lower C3, and C4 levels in all groups but groups C and F （ P 〈 0.05 ）, indicating that dietary supplementation of clove leaf would to some extent inhibit the growth and immunity in Amur sturgeon.
