Abstract: Thirtytwo DurocLandraceYorkshire piglets of 28dayold were randomly divided into two groups. Control group fed with basal diets and experimental group fed with basal diets supplemented with 0.25% the culture of Acrermonium terricola.The experiment was carried out for 30 d. Compared with the control group the body weight gain of experimental group increased significantly（P<0.05），feed efficiency was improved，the rate of diarrhea decreased distinctly. Level of immune antibody of hog cholera was also increased significantly（P<0.01）. These results showed that the culture of Acrermonium terricola could accelerate the body weight gain and improved the immune function of piglets.

Key words: culture of Acrermonium terricola; piglets; weight gain; antibody
