  Improvement of the immune system response along with increase in performance and growth factors are important goals of the modern poultry industry. The aim of this study was to determine the effect of combination of probiotic, lactase enzyme and special antibodies on improving the small intestinal histomorphology and growth factors in broiler chickens. For this purpose, 96 broilers (Ross 308) were distributed randomly into two groups of 48 with 4 replicates of 12 chicks. In the experimental group, two grams of the test compound was used in water for 42 days. All birds were weighed at the end of each week in order to investigate their growth factors. For histomorphological characterization, two broilers from each replicate were selected and the entire small intestine was removed and sent to the histology lab. The results indicated a significant difference in growth factors between the two groups from the third to the sixth week (p<0.01). Crypt depth, villi height, thickness of muscular and mucosal layers  and the number of goblet cells in different parts of the intestine was significantly different between the two groups (p<0.01). The results showed that this compound can improve intestinal histomorphology and increase nutrient absorption and efficiency of food and improve growth factors therefore it seems that its use can improve the standard of growth in the poultry industry.
