| 【Objective】The effects of β-glucan on the growth performance, non-specific immunity and antioxidant
indexes of young Truogx sinensis were studied under the condition of green ecological breeding.【Method】180 young Truogx
sinensis with the body mass of 200 (±10)g were randomly divided into 3 groups. Three tests were performed in each group
and 20 young T.sinensis were tested each time, and fed with basic feed(control group) and test feed with 200 mg/kg (G200)
and 1 000 mg/kg(G1000) doses of β-glucan. After 120 days, the increased weight, the ratio of body weight to viscera and
the ratio of viscera to liver of the young T. sinensis were calculated. The contents of catalase in whole blood, the lysozyme,
alkaline phosphatase, acid phosphatase, superoxide dismutase activity and malondialdehyde in serum were determined. 【Result】 There were no significant differences in increased weight, ratio of body weight to viscera and ratio of viscera to liver
in the tested groups. The Lysozyme activity (LYZ) in the serum of G1000 group was significantly higher than that of the control
group and G200 group while the difference between the G200 group and the control group was not significant. The alkaline
phosphatase(AKP) activity in the G200 group and G1000 group was increased significantly compared with the control group.
The superoxide dismutase(SOD) activity of the G200 group was significantly higher than that of the control group and the G1000
group. No significant difference in acid phosphatase(ACP), catalase (CAT) activity and malondialdehyde(MDA) was observed
in all groups(P >0.05).【Conclusion】 The addition of a proper amount of β-glucan in feed could help to improve the nonspecific immune function and antioxidant level of the young T. sinensis without affecting its growth performance. |
