Abstract

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 chickens 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 significantly 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.
