| 摘 要： | 在基础饲料中分别添加0.5 g/kg、1.0 g/kg、1.5 g/kg、2.0 g/kg、2.5 g/kg的云芝多糖,饲喂(9.0±1.0)g奥尼罗非鱼(rom is niloticus×O.aureus)56 d后,测定罗非鱼增重率、特定生长率、饵料系数、血清溶菌酶活性和血清补体替代途径溶血(ACH50)活力。结果表明:添加量为0.5 g/kg时,试验组罗非鱼增重率和特定生长率显著增高,饵料系数显著降低;添加量为1.0 g/kg时,血清溶菌酶和ACH50活性达到最高,但与对照组差异不显著,而添加量为2.5 g/kg组的血清溶菌酶活性显著低于对照组。 |

| Abstract: | Effects of different dietary Coriolus versicolor polysaccharide levels(0 g/kg,0.5 g/kg,1.0 g/kg,1.5 g/kg,2.0 g/kg,2.5 g/kg)on growth,serum lysozyme activity and complement activity of hybrid tilapia(initial mean weight:9.0±1.0)were studied.The results showed that for 0.5 g/kg group,the weight gain ratio(WGR)and specific growth ratio(SGR)increased significantly,as well as feed efficiency ratio(FER)decreased remarkable;serum lysozyme activity and ACH50 activity reached the highest in 1.0 g/kg group,but there was no significant difference,as well as 2.5 g/kg group had remarkable lower serum lysozyme than control group. |
| Keywords: | Coriolus versicolor polysaccharide hybrid tilapia(Oreochromis niloticus×O aureus) growth lysozyme complement |
