BACKGROUND: Population growth and the need for food, especially proteins, have increased the interest in using inexpensive and available supplements to increase protein production. ObjectiveS: The aim of this study was to evaluate the effect of Qom region zeolite as a supplement to the histological and histochemical structure of broiler chicken intestine and to compare it with commercial zeolite. Methods: In this experimental study a total of 200 broiler chicks were purchased from Qom poultry and randomly divided into five groups including the control group; the experimental group of Qom zeolite which was subsequently subdivided into three different doses including (Z1 = 0.5 %, Z2 = 1%, Z3 =1,5%); and finally the anzymite group which received the commercial zeolite. 42 days later, 10 samples were selected from each group and after tissue preparation, the slides were stained with hematoxylin-eosin, PAS period, and toluidine blue; then microscopic assays were applied using the Image-j 1.49f software. Data analysis was done with SPSS 20 and One-way ANOVA and Tukey’s post hoc test. PResults: The height of the epithelial cells decreased in the anzymite group but the number of mucosal glands and goblet cells increased significantly (P<0.05). Except for Z1 group in other Qom zeolite treatment groups (Z2 and Z3), the number of goblet cells increased significantly (P<0.05). Therefore, the effect of zeolite higher than 1.5% may be comparable with anzymite. Conclusions: Our results showed that zeolite does not have any effect on increasing the absorption rate of the small intestine, but could stimulate the function of goblet cells and intestinal glands, so Qom zeolite with higher percentage could have the same effect as anzymite
