Summary To evaluate the effect of dietary dried fermented ginger (DFG) on intestinal villous histological alteration and growth performance, 64 Marshall Chunky male broilers were divided into four groups, each with four replicates of four chickens. Birds were fed the basal commercial mash diet supplemented with DFG at 0 (control), 5, 10 and 20 g/kg for 42 days. With increasing dietary DFG levels, feed intake tended to decrease and significantly decreased in the 20 g/kg DFG group (p < 0.05). Weight gain was higher in all the DFG groups, with the highest in the 10 g/kg DFG group (p < 0.05), resulting in an improved feed efficiency in all the DFG groups. Intestinal villus height, villus area, cell area and cell mitosis in all the intestinal segments were higher in all the DFG groups than in the control group. Protuberated cells and cell clusters were found in all the DFG groups, suggesting that the intestinal villi and cells might be hypertrophied. The present results indicate that dietary DFG can be used as a natural feed additive to induce broiler growth performance as a result of stimulation of morphological maturation and in consequence intestinal function.
