“…In addition, broilers fed WB had similar growth performance compared to those fed AGP, indicating that WB may be an effective alternative to antibiotics in poultry diets. Similar beneficial effects of DF on broiler performance were also reported in previous studies ( Adibmoradi et al., 2016 ; Jiménez-Moreno et al., 2016 ). However, there are also some conflicting findings suggesting that DF had no effects or negative effects on the growth performance in broilers ( Sacranie et al., 2012 ; Walugembe et al., 2014 ).…”

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.

“…Dietary fiber supplementation had no remarkable effect on the performance of broiler chickens. Although there are studies reporting positive effect of SF- and IF-containing diets on the growth performance of broilers ( González-Alvarado et al., 2007 , González-Alvarado et al., 2010 , Jiménez-Moreno et al., 2009 , Jiménez-Moreno et al., 2010 , Jiménez-Moreno et al., 2016 , Adibmoradi et al., 2016 ), declined performance were observed in some other experiments on broilers ( Janssen and Carré, 1985 ) and turkey ( Sklan et al., 2003 ). These contradictory results may depend upon many factors such as dietary fiber source or supplemental fiber level and also health status of experimental animals.…”

This experiment was designed to investigate the effects of a dietary organic acid (OA) mixture and 2 fiber sources on performance, intestinal morphology, immune responses and gut microflora in broilers. A total of 390 one-day-old broiler chicks (Ross 308) were allocated to 6 dietary treatments with 5 replicate pens and 13 chicks each based on a factorial arrangement (2 × 3) in a completely randomized design. The experiment lasted 42 d. The following experimental diets and as well as their interaction were considered: a basal diet supplemented with or without OA (0 or 1 g/kg) and 2 fiber sources (sugar beet pulp [soluble fiber] or rice hull [insoluble fiber]; 0 or 30 g/kg). Dietary supplementation of OA increased daily weight gains of broilers across the entire rearing period ( P < 0.05). The dietary fibrous materials did not affect the performance of broilers. Antibody titer against influenza disease virus was higher in birds fed diets containing rice hull compared with other experimental groups ( P < 0.05). The population of Lactobacillus bacteria was greater in birds fed OA-added diets without or with 30 g/kg rice hull supplementation compared with other experimental groups ( P < 0.05). In conclusion, dietary supplemental OA improved performance of broilers, and dietary supplemental OA with rice hull enhanced humoral immune responses.

“…Considering that a significant portion of nutrient absorption in the small intestine takes place in the jejunum, the shorter villus height in the jejunum due to choline deficiency could be a factor in lower feed intake and growth rate in chickens (Adibmoradi et al 2016). The effect of garlic powder in increasing the VH seems a remarkable finding, and suggests an offsetting effect of garlic on the negative effect of choline deficiency through improved absorption in the small intestine.…”

An experiment with two dietary choline levels (recommended level or 75% of the recommended level) and three dietary garlic powders (0, 5 or 10 g/kg) was conducted on broiler chickens. Three hundred thirty mixed sex 1-day-old Ross 308 broiler chickens were randomly assigned to six dietary treatments, each housed in four replicate pens with 14 birds per pen. Dietary garlic increased the finisher phase's feed intake. Dietary 10 g/kg of garlic powder and recommended choline level improved body weight gain. Choline deficiency increased feed conversion ratio (FCR). The jejunum villi height was decreased in birds consuming the choline deficient diets; however, villi height was increased by garlic powder. In the duodenum and ileum, 10 g/kg diet garlic powder significantly increased crypt depth compared to those of the treatments with no garlic. This study showed that reducing dietary choline to 75% of the recommended level reduced the growth rate of broilers that could be compensated by dietary garlic. This effect was partly due to higher finisher phase feed intake.
