From: Dietary fiber in poultry nutrition and their effects on nutrient utilization, performance, gut health, and on the environment: a review

Source Inclusion level Species Response Reference
SBM/Oat hull 3%, 5% Broiler Increased gizzard weight and reduced it’s pH [4]
SBP/Pea hull 7.5% Broiler Increased abrasion of the mucosal surface of the small intestine, shortened the villus, and increased mucus output [24]
Pea hull 2.5% Broiler Increased VH:CD ratio [24]
SFM 40–45 g/kg Pullet Increased VH, villus weight, the VH:CD ratio and surface area [25]
SFM 47 g/kg Layer Increased VH, villus weight, the VH:CD ratio and surface area [26]
SFM 97 g/kg Layer Decreased VH, villus weight, the VH:CD ratio and surface area [26]
Soyabean hull 40 g/Kg Broiler Decreased negative effects of coccidiosis on VH:CD [55]
Rice hull 40 g/Kg Broiler Decreased negative effects of coccidiosis on duodenal villus height [55]
Wheat bran 30 g/Kg Broiler Increased VH and VH:CD ratio [56]
Chitooligosaccharide 5 mg/egg (in ovo injection) Broiler Increased beneficial gut bacteria [62]
Soybean hull 7% Broiler increased acetic, propionic, isobutyric and butyric acid, lactic and succinic acid in cecal contents and depressed formic acid production [76]
Alfalfa extract 0.06% Broiler Increased thymus, spleen and bursa weight; Proliferation of T and B lymphocytes; Increased anti-NDV serum; Enhanced overall immunity [19]
Algae-derived polysaccharides 2500 mg/kg Broiler Increased VH of jejunum and ileum [85]
Algae derived polysaccharides 4000 mg/kg Broiler Increased the VH of duodenum and ileum [85]
Yeast derived β-glucans 0, 0.02%, or 0.1% Broiler Altered the cytokine-chemokine balance [86]
Raffinose 1.5, 3.0, and 4.5 mg in 0.2 mL of an aqueous diluents Broiler Increased VH and VH:CH ratio; improved immunity and gut health [92]
Yeast cell 2.5 g/kg Broiler Enhanced antibody titers, IgM and IgA concentration, serum lysozyme and better gut morphology [97]
Yeast culture 20 g/t Turkey Reduced transport stress [103]
Wheat based diet (arabinoxylans) 0.1% (wt/wt) Broiler Increased production of cecal SCFA [106]
Arabinoxylooligosaccharides 0.4% or 0.2% Broiler Maintained gut health [107]
Barley-derived arabinoxylans 200 mg/kg body weight or 300 mg/kg body weight Broiler Enhanced macrophage activity [109]
Fructooligosaccharide 0.5% Broiler Upregulated interferon-γ and IL-10 expression in ileum [124]
