“…The beneficial effects of WB on nutrient digestibility may be attributed to the effects of WB on gastrointestinal development and the concomitant increase in digestive enzyme secretion [ 3 ]. Similar results were also reported by Donadelli et al [ 6 ], in which birds fed fiber containing diet (30 g/kg cellulose, beet pulp, or miscanthus grass) had greater ATTD of DM, OM and GE in broilers compared with those fed the no fiber dietary treatment. In contrast, the negative effects of DF on nutrient digestibility were also observed in previous studies [ 21 , 22 ].…”

“…However, DF has attracted increasing attention due to various beneficial effects on gut health [ 4 ]. However, further studies demonstrated that there is a lack of consistency with regard to the effects of DF, suggesting that the effects of DF depend on their physicochemical characteristics [ 5 , 6 ]. Soluble dietary fiber (SDF) generally has a viscous structure, thus increasing digesta viscosity and reduces passage rate, and eventually reduces nutrient utilization [ 3 ].…”

“…Soluble dietary fiber (SDF) generally has a viscous structure, thus increasing digesta viscosity and reduces passage rate, and eventually reduces nutrient utilization [ 3 ]. In contrast, insoluble dietary fiber (IDF) has a nonviscous structural component, and recent studies in poultry have demonstrated that moderate amounts (20–30 g/kg) of IDF to be beneficial to nutrient utilization by improving gastrointestinal development and enzyme secretion [ 6 , 7 ]. Therefore, supplementing insoluble dietary fiber to broiler diets may be a feasible method to improve feed efficiency.…”

There is increasing evidence showing that moderate amounts of insoluble dietary fiber can improve nutrient utilization by positively influencing the physiology of the gastrointestinal tract. The present study was conducted to investigate the effects of wheat bran as a source of insoluble fiber on nutrient digestibility, serum antioxidant status, gastrointestinal development, digestive enzyme activities and intestinal morphology in broiler chickens. A total of 96 one-day-old male Arbor Acre broiler chickens were assigned to two treatments with six replicate cages per treatment and eight birds per replicate for 42 d. Dietary treatments consisted of the control group (CON, control diet) and wheat bran group (WB, 30 g/kg wheat bran). Inclusion of WB increased (p < 0.05) the digestibility of dry matter, organic matter, gross energy and crude protein on Day 42. Birds fed WB had lower (p < 0.05) serum total cholesterol concentration on Day 21, and lower (p < 0.05) serum concentrations of low-density lipoprotein, total cholesterol and total triglyceride on Day 42. Inclusion of WB increased (p < 0.05) serum glutathione peroxidase activity on Day 21 and superoxide dismutase activity on Day 42, but tended (p = 0.07) to decrease serum malondialdehyde concentration on Day 21, and significantly decreased (p < 0.05) serum malondialdehyde concentration on Day 42. Birds fed WB had a greater (p < 0.05) relative weight of gizzard on both Day 21 and 42. Inclusion of WB increased (p < 0.05) activities of amylase and trypsin in pancreas and jejunal mucosa on Day 21, and increased (p < 0.05) amylase activity in pancreas and jejunal mucosa. Birds fed WB had greater (p < 0.05) villus height and villus height to crypt depth ratio in jejunum and ileum on Day 42. In conclusion, supplementation of 30 g/kg WB enhanced nutrient digestibility by improving antioxidant status, gizzard development, intestinal digestive enzyme activities and morphology of broilers.

“…Maintaining gut health is essential to improve growth performance and the overall health of animals, implying that DF may be a potential alternative to antibiotics in poultry diets ( Jha et al., 2019 ). However, results regarding the effects of DF on poultry have been inconsistent, probably due to its different physicochemical properties ( He et al., 2015 ; Donadelli et al., 2019 ). Soluble dietary fiber ( SDF ) generally increases digesta viscosity, delays gastric emptying, and thereby reduces nutrient digestibility and feed consumption, eventually resulting in growth inhibition ( Mateos et al., 2012 ).…”

“…Soluble dietary fiber ( SDF ) generally increases digesta viscosity, delays gastric emptying, and thereby reduces nutrient digestibility and feed consumption, eventually resulting in growth inhibition ( Mateos et al., 2012 ). In contrast, insoluble dietary fiber ( IDF ) at moderate levels (2–3%) has been shown to stimulate gizzard development and digestive enzyme secretions, resulting in better nutrient utilization and growth ( Donadelli et al., 2019 ; Jiménez-Moreno et al., 2019 ). Therefore, it may be useful to supplement moderate levels of IDF rather than SDF in poultry diets.…”

This experiment was conducted to evaluate the effects of wheat bran ( WB ) and antibiotics on growth performance, intestinal immunity, barrier function, and microbial composition in broiler chickens. A total of 168 one-day-old male Arbor Acre chicks were allocated to 3 treatments consisting of 7 replicates with 8 birds per replicate. The 3 treatments were: an antibiotic-free control diet (control, CON), CON + 75 mg/kg chlortetracycline as an antibiotic growth promoter ( AGP ), and CON + 3% WB. Birds fed AGP and WB had greater ( P < 0.05) ADG during days 1 to 21 and lower ( P < 0.05) feed-to-gain ratio during each phase than those fed CON. The WB supplementation reduced ( P < 0.05) serum concentrations of tumor necrosis factor-α and diamine oxidase activity compared with CON on both day 21 and 42. The AGP and WB supplementation decreased ( P < 0.05) interleukin-1β concentration in jejunal mucosa on day 21 and increased ( P < 0.05) secretory immunoglobulin A concentration in jejunal mucosa on day 21 and 42. The relative expression of occludin in jejunal mucosa was upregulated ( P < 0.05) in WB than in CON on day 21. Moreover, both AGP and WB supplementation upregulated ( P < 0.05) the relative expression of zonula occludens-1 in jejunal mucosa on day 21 and 42. The WB supplementation enhanced the α-diversity of cecal microbiota, as evidenced by the increased Shannon index ( P < 0.05). At the phylum level, the phylum Firmicutes was enriched ( P < 0.05) in WB. At the genus level, the WB supplementation enriched ( P < 0.05) Lachnoclostridium and Butyricicoccus . The WB supplementation increased ( P < 0.05) cecal total short chain fatty acids concentrations on day 21 and 42, and butyric acid concentrations on day 42 compared with CON. Collectively, supplementation of 3% WB could promote growth by improving intestinal immunity, barrier function, and microbial composition in broilers. Thus, WB may have a role in replacing antibiotics for improved growth performance and intestinal health in broilers.

Adding insoluble fiber to diet of broilers has been reported to improve intestinal health and promote growth performance. Bamboo powder is a cheap raw material with rich insoluble fiber. This study aims to explore the effects of feeding micronized bamboo powder (MBP) on growth performance, serum biochemical indexes, intestinal microflora, and metabolism of broilers. A total of 1440 1-day-old slow-growing Ephedra chickens were randomly divided into three groups considering gender and body weight: (1) Group D: feeding with basal diet without antibiotics; (2) Group E: feeding with basal diet supplemented with 5% rice bran (RB); (3) Group F: feeding with basal diet supplemented with 1% MBP. Each group involved 8 replicates feeding for 22 days, with 60 chickens per replicate. Various indexes were detected. For the growth performance, the weight gain and feed consumption ratio (G: F) of Group F supplemented with MBP is 0.57 ± 0.04, which is significantly higher than that of E group supplemented with RB (0.52 ± 0.01, P < 0.05). For the serum biochemical indexes, the glutathione peroxidase activity in Group F is significantly higher than that of Group D, while the malondialdehyde content is significantly lower than that of Group D and Group E (P < 0.05 for all). The fresh cecal chyme is taken for determination. In Group F, the α diversity index Faith_pd is significantly lower in Group F than that of Group D. The microorganism species in cecal chyme of Group F and Group E are also different. The metabolic pathways of Group F, mainly in fatty acid metabolism, amino acid metabolism and intestinal immune IgA production, were different from those of Group D and Group E. Adding 1% MBP to broiler diet can enhance the anti-oxidant capacity, improve chyme microflora, regulate the metabolism pathways responsible for intestinal fatty acids, amino acids, and immunity.
