Nutraceuticals are not only nutritionally beneficial for animals, but also their use as feed supplements may reduce environmental contamination. The effect of fermented defatted ‘alperujo’, an olive oil by-product, supplementation on the intestinal health of broiler chickens was assessed by analyzing the intestinal mucosal morphology of the duodenum and the cecum. The microbiota of the cecum was also characterized by analyzing the V3-V4 region of the 16S rRNA gene on days 7, 14, 21, 28, 35 and 42. Supplemented broilers from 14 to 35 days old showed an increase in villus height in the duodenum. This increase likely improved digestibility and absorption capacity during growth, leading to the observed increase in body weight at the day 35 of life. A progressive increase in crypt depth in both the duodenum and the cecum was also observed. This modification likely enhanced epithelial renewal, thus safeguarding the turnover capacity of the intestinal mucosa. Our molecular analysis of cecal microbiota suggests that this dietary supplement may favor the growth of certain bacteria and may control the spread of pathogenic bacteria by means of competitive exclusion
