Group Ⅰfed with tap water was the control, while group Ⅱ, group Ⅲ and group Ⅳ were fed with 0.5, 1.0, 2.0 g·L-1 doses of ex- tracts from Codonopsis, respectively. Sixteen partridge chickens on empty stomach in the morning were randomly taken at the age of 28, 35, 42, 49 and 56 days, and jejunum and ileum were taken out, which were fixed for 24 hours with Bouin at room temperature, After
