本研究旨在探讨饲粮中添加不同水平大豆异黄酮（ ISO ）对固始鸡小肠形态结构的影响。将80只1日龄固始鸡雏鸡随机分成4组：对照组（饲喂基础饲粮）、3 mg/kg大豆异黄酮组、6 mg/kg大豆异黄酮组、9 mg/kg大豆异黄酮组，每组20只鸡。结果表明：1）大豆异黄酮对固始鸡体重和小肠长度没有显著影响（ P＞0．05）；2）大豆异黄酮显著影响了空肠和回肠绒毛高度、隐窝深度和绒毛高度/隐窝深度（ V/C）值（ P＜0．05）；3）大豆异黄酮对固始鸡35日龄十二指肠和21、35日龄回肠杯状细胞的数量具有显著影响（ P＜0．05）；4）除35日龄空肠外，大豆异黄酮对固始鸡肠道肥大细胞的数量具有显著影响（ P＜0．05）。综上，在本试验条件下，固始鸡饲粮大豆异黄酮的最适添加水平为6 mg/kg。

This study was conducted to investigate the effects of different adding levels of soybean isoflavones ( ISO) on the morphological structure of the small intestinal of Gushi chickens. Eighty 1-day-old Gushi chick-ens were randomly divided into four groups ( with 20 chickens per group) as control group ( feeding with basal diet) , 3 mg/kg ISO group, 6 mg/kg ISO group and 9 mg/kg ISO group. The results showed as follows:1) ISO had no significant effect on body weight and length of the small intestine of Gushi chickens ( P>0.05) . 2) ISO had significantly effect on villus height, crypt depth and the ratio of villus height to crypt depth of jejunum and ileum ( P<0.05) . 3) ISO had significantly effect on the number of goblet cells of duodenum at 35 days of age and ileum at 21 and 35 days of age ( P<0.05) . 4) Expected jejunum at 35 days of age, ISO had signifi-cantly effect on the number of mast cells of small intestine ( P<0.05) . The results indicate that 6 mg/kg is the optimal add level of the ISO of Gushi chickens under the condition of this study.
