摘　　要：该试验以翘嘴鲌(Culter ablurnus)为试验对象,将相同浓度的抗应激饲料添加到基础饲料中,研究抗应激饲料作为饲料添加剂喂养不同时长(0、7、14、21、28和35 d),分为6组(S0、S1、S2、S3、S4、S5)对翘嘴鲌肠道组织结构的影响。结果表明,肌层厚度方面,总体呈现随着时间的增加逐渐增厚。同对照组相比,S1、S2与S3无明显差异,S4、S5有统计学意义差异(P<0.05)。褶皱高度方面,总体呈现随着时间的增加逐渐增厚。同对照组相比,S1、S2、S3差异不具统计学意义,S4、S5出现极具统计学意义差异(P<0.05)。褶皱宽度方面,总体呈现随着时间的增加逐渐增大。同对照组相比,S1、S2、S3和S4差异均不具统计学意义,S5与对照组有具统计学意义差异(P<0.05)。横截面积方面,总体呈现随着时间的增加逐渐变大。同对照组相比,每组差异均具统计学意义(P<0.05),S1组和S3组增长最为明显。In this experiment, same concentration of anti stress feed was added to C. ablurnus basic feed to research the influence on C. ablurnus intestinal structure with different feeding day(0 days, 7 days, 14 days, 21 days,28 days, 35 days). The results showed that the thickness of muscle layer increased gradually and the fold height showed gradually thickening as time gone on. Compared with the control group, S1, S2 and S3 were not significantly different, S4, S5 showed a very significant difference(P<0.05) as time prolonged. The fold width showed a gradually increasing with the increase of time. Compared with the control group, S1, S2, S3 and S4 were not significantly different, S5 and control group had significant differences(P<0.05). On cross sectional area, it became more and more larger with the increase of time. Compared with the control group, the difference in each group was highly significant(P<0.05).
