White Leghorn chickens were divided into the control, low-carbohydrate (CHO), and CHO-free groups to investigate dietary CHO's significance on histological features of chicken ileal mucosa. Paraffin sections of distal ileum from each chicken were stained by periodic acid-Schiff reaction and subjected to morphometrical analysis. Most villi in the control group had a fingerlike shape but those of the experimental groups showed irregular shapes. Villus height, crypt depth and the number of mitotic cells per crypt were significantly lower in the CHO-free group than in the control group. The density of goblet cells also showed a significant decreasing trend with a reduction in dietary CHO level. In conclusion, dietary CHO positively affects the proliferation of epithelial cells in the chicken ileum.
将白来航鸡分为对照组、低碳水化合物（CHO）组和无CHO组，以研究日粮中CHO对鸡回肠黏膜组织学特征的重要性。对每只鸡的回肠远端石蜡切片进行过碘酸-希夫反应染色，并进行形态计量分析。对照组的大多数绒毛呈指状，但实验组的绒毛形状不规则。无CHO组的绒毛高度、隐窝深度和每个隐窝有丝分裂细胞数均显著低于对照组。随着日粮CHO水平的降低，杯状细胞密度也呈现出显著下降趋势。总之，日粮CHO对鸡回肠上皮细胞的增殖有积极影响。
