Problem statement: As the intestinal function is intimately affected by fed diets, many kinds of natural substances and probiotics have been supplemented to broilers to raise poultry productivity due to activating intestinal function. Besides, the intestinal histology is clearly altered by intestinal functions. The aim of this study was to investigate whether Sugar Cane Extract (SCE) and commercial probiotic (SPB), either alone or in combination, could improve growth performance and how intestinal histological alterations would be observed in these birds. Approach: A total of 64, 7-d-old male broiler chicks were randomly assigned to 4 treatment groups, consisting of 4 replicates of 4 birds each. Commercial mash starter and finisher diets were supplemented with 0.05% SCE, 0.4% SPB, or a mixture of 0.05% SCE and 0.4% SPB (SCE + SPB). Results: Body weight gain was better in all the experimental groups than the control. The greatest improvement was observed in the SCE + SPB group. Most values of villus height, villus area, cell area and cell mitosis in all intestinal segments were higher (p<0.05) in the experimental groups than in the control group. Most epithelial cells on the villus apical surface of the experimental groups were composed of protuberant cells. In addition, cell clusters composed of these cells were observed in the duodenum of the SCE + SPB group and in the jejunum of the SCE group. In the ileum, the SCE + SPB group had the most protuberant cells. Conclusion: The present results of enhanced light microscopic parameters and protuberant epithelial cells in SCE and SPB groups suggest that the intestinal villi and epithelial cells might be hypertrophied by SCE and SPB. The fact that a synergistic effect was observed with regard to growth performance and intestinal histology in the SCE + SPB group suggests that SCE is a good supplement to probiotics.
