The aim of this experiment was to study the effect of bee propolis added to the balanced diet on growth performance、intestinal development and blood characteristics of the White Roman geese. The experiment were divided into four treatment groups；G1group(G1): the control group which were no antibiotic used; G200 group(G200) which were added 200ppm bee propolis to the balanced diet; G400 group(G400) which were added 400ppm bee propolis to the balanced diet; G800 group(G800) which were added 800ppm bee propolis to the balanced diet. The final weight of four groups at twelve week age were 4.80、4.74、4.78、and 4.87kg, respectively. There were no significant among groups (p>0.05). The evaluation of intestinal morphalogy at 12 week age of White Roman geese were included villus height、villus width、villus circumference、villus area、and crypt depth of duodenum, jejunum, and ileum. The results were shown that in the duodenum there were no significant among groups (p>0.05); in the jejunum the villus area of G800 and crypt depth of G400 were significant among groups (p<0.05); in the ileum the villus height and crypt depth of G400 were significant among groups (p<0.05). So the high dosage bee propolis added to the diets the intestinal development could get the better growth in geese. As for the blood characteristics the cholesterol value of G200、G400 and G800 were lower than that of control group at the 12 week. Hence bee propolis added to the diets could improve the development of small intestine. But there were no improvement the growth performance in the White Roman geese.
