The aim of this work was to evaluate the microscopic changes in the small intestine of rats after administration of the pollen addition in diet. Experimental groups A, B and C (10 rats each) were given the addition of pollen in concentration of 0.2%, 0.5% and 0.75%, respectively for 90 days in food. Using the quantitative morphometrical methods, statistically significant increase of intestinal villi length (p<0.0001) and Lieberkühn crypts depth (p<0.0001) in jejunum in the experimental groups A and B were found when compared to control without the pollen addition. In experimental group C we have found only statistically significant increase of intestinal villi length (p<0.0001) but statistically significant decrease of Lieberkühn crypts depth (p<0.0001) compared to control group. The results of our work show that the addition of pollen in the diet affects the structure of the small intestine mucosa of rats. The increased length of intestinal villi could modify the absorption rate in the digestive system.
