Two hundred forty male Avian Farms broiler chicks, 1 d of age, were randomly allocated to four treatments, each of which had five pens of 12 chicks per pen. The chicks were used to investigate the effects of fructooligosaccharide (FOS) on digestive enzyme activities and intestinal microflora and morphology. The chicks received the same basal diet based on corn-soybean meal, and FOS was added to the basal diet at 0, 2.0, 4.0, and 8.0 g/kg diet at the expense of corn. Addition of 4.0 g/kg FOS to the basal diet significantly increased average daily gain of broilers. The feed-to-gain ratios were significantly decreased for the birds fed diets with 2.0 and 4.0 g/kg FOS versus the control. Addition of 4.0 g/kg FOS enhanced the growth of Bifidobacterium and Lactobacillus, but inhibited Escherichia coli in the small intestinal and cecal digesta. Supplementation of 2.0 or 4.0 g/kg FOS to chicks significantly improved the activities of amylase compared to the control (12.80 or 14.75 vs. 8.42 Somogyi units). A significant increase in the activities of total protease was observed in 4.0 g/kg FOS-treated birds versus controls (83.91 vs. 65.97 units). Morphology data for the duodenum, jejunum, and ileum showed no significant differences for villus height, crypt depth, or microvillus height at the duodenum. By contrast, addition of 4.0 g/kg FOS significantly increased ileal villus height, jejunal and ileal microvillus height, and villus-height-to-crypt-depth ratios at the jejunum and ileum and decreased crypt depth at the jejunum and ileum. However, addition of 8.0 g/kg FOS had no significant effect on growth performance, digestive enzyme activities, intestinal microflora, or morphology.

(2009, background): “A shortening of the villi and deeper crypts may lead to poor nutrient absorption, increased secretion in the gastrointestinal tract, and lower performance (Xu et al., 2003).”
- Effects of the lactoferrin (LF) on the growth performance, intestinal microflora and morphology of weanling pigs (2007, methodology): “Changes in intestinal morphology such as shorter villus and deeper crypts have been associated with the presence of toxins (Xu et al., 2003).”
- Probiotics and prebiotics in animal feeding for safe food production. (2010, background): “Xu et al. (2003) found a dose-dependent effect of fructooligosaccharides (FOS) on average daily gain; whereas Juskiewicz et al. (2006) reported no impact on the performance or productivity of turkeys after feeding for eight weeks with different amounts of FOS.”
- The effect of inulin on broiler chicken intestinal microflora, gut morphology, and performance (2012, background): “…information exists regarding the effects of inulin on the histology of the small intestine, although a few reports are available showing that the villus height of the small intestine is increased in broilers supplemented with fermentable carbohydrates like fructooligosaccharides (Xu et al., 2003).”
- Effect of Formic Acid and Plant Extracts on Growth, Nutrient Digestibility, Intestine Mucosa Morphology, and Meat Yield of Broilers (2007, background): “Antimicrobial agents are known to reduce the intestinal microbial load, which in turn reduces the presence of toxins at this level that are associated with changes in intestinal morphology, such as shorter villi and deeper crypts [44].”
