Abstract:

To study the effect of soybean isoflavones on the distribution of lymphocyte in small intestine mucosal of ducks. 200 KaJi-Cambel ducks were randomized into 2 groups, the control group and the experiment group. Each group has 100. The control was fed basal diet. Soybean isoflavones was supplemented in basal diets of experiment group by 0.04%. The experiment stage was 40 days. the experiment ducks were slaughtered at the end of experiments.The sample of small intestine of every group ducks were sampled. The samples were fixed in the Bouin liquid, produced the paraffin slice and H?E dyeing. The slice was observed and photograph under the microscope of OlympuCH-30. The result reveals that the intramucosal lymphocyte in small intestine of experiment group ducks were increased than the control group.Immune function of small intestine mucosal was promoted by the soybean isoflavones.
