“…These effects are interpreted to indicate increased stability of the microbiota (Bhandari et al, 2008;Opapeju et al, 2009), although no association with clinical responses appeared in this experiment. The source and amount of fiber in the diet can change the intestinal microbial communities (Pieper et al, 2008;Reilly et al, 2010) because fiber is an important substrate to support the microbial activity, mainly through fiber fermentation. In the present study, all of the effects of DDgS in bacterial communities occurred in the ceca, where most fiber fermentation occurs.…”

Chicks were used to determine whether dietary corn distillers dried grains with solubles (DDGS) may prevent or ameliorate Eimeria acervulina (EA) infection. The experiment had a completely randomized design with a factorial arrangement of 3 diets (inclusion of 0, 10, or 20% DDGS) × 2 challenge treatments: inoculation with distilled water or with 10(6) sporulated EA oocysts. Each treatment was replicated with 8 pens of 5 chicks each. Experimental diets were fed from 7 to 21 d of age. Inoculation occurred on d 10 of age, considered postinoculation (PI) d 0. Feed intake and BW were measured on PI d 0, 7, and 14. Excreta samples were collected on PI d 0, 5 to 10, 12, and 14 to detect oocysts. On PI d 14, mucosal samples were collected for the analysis of bacterial populations by denaturing gradient gel electrophoresis, using the V3 region of bacterial 16S ribosome. The EA challenge reduced (P < 0.001) ADG by 17%, ADFI by 12%, and G:F by 6% from PI d 0 to 7, and by smaller percentages from PI d 7 to 14. Diet and challenge treatments did not interact in the chick performance, so dietary DDGS did not alleviate EA infection. Oocysts in excreta were detected PI only in EA chicks and no dietary effects were found. Cecal bacterial population was changed (P < 0.05) by effect of dietary DDGS and EA infection. The cecal bacterial diversity among chicks within treatments and homogeneity among chicks within treatments were reduced by EA infection (P = 0.02 to 0.001) and increased by feeding 10% DDGS (diet quadratic, P < 0.001). In summary, feeding up to 20% DDGS to young chicks did not prevent or ameliorate EA infection. Changes in cecal microbiota of chicks fed 10% DDGS can be interpreted as beneficial for intestinal health.

Soaking the cereal fraction of a liquid diet prior to feeding (C soak), and/or carbohydrase enzyme supplementation (ENZ) are likely to modulate both feed and intestinal microbial populations and improve feed efficiency (FE) in pigs. To test this hypothesis, a total of 392 grow-finisher pigs (~33.4 kg, 7 pigs/pen) were randomly allocated to 4 treatments in a 2 × 2 factorial arrangement for 70 days as follows: (1) fresh liquid feed (Fresh); (2) Cereal soaked liquid feed (Soak); (3) Fresh + ENZ and (4) Soak + ENZ. An interaction between ENZ and C soak was found for average daily gain (ADG) during the growing phase (day 0 to 21; P < 0.05) where pigs fed the Soak + ENZ diet had higher ADG than pigs fed the Fresh + ENZ diet. No treatment effect was found for ADG thereafter. Enzyme supplementation increased total tract nutrient digestibility (P < 0.05) and reduced caecal VFA concentrations (P < 0.05) but did not improve pig growth or FE. Both C soak and ENZ modulated intestinal microbiota composition; increasing abundance of bacterial taxa that were negatively correlated with pig growth and reducing abundance of taxa positively correlated with pig growth and caecal butyrate concentration. In conclusion, both strategies (C soak and ENZ) improved nutrient digestibility in pigs and modulated intestinal microbiota composition.

“…Production of SCFA also prevents growth of potential pathogens [11] . Many researchers reported that β-glucan has positive effects on probiotic bacteria such as lactobacilli and bifidobacteria in gut microflora by animal experiments [12][13][14] . But there is not enough research about impact of β-glucan to intestinal microflora such as Lactobacillus, coliform, Enterobacteriaceae, enterococci.…”

In this study we aimed to evaluate the effect of orally administered β-glucan and/or dietary restriction on Lactobacillus spp., coliforms, Enterobacteriaceae and enterococci counts in rat faeces. For this aim, rats were divided into three experimental groups: i) first group animals received normal diet for 6 months and administrated orally with β-glucan (20 mg/kg for bodyweigth) over the last 14 day of experiment, ii) second group was dietary restricted animals for 6 months and receiving β-glucan as those of first group animals, iii) last group was the control group rats receiving only ad libitum feed. Compared to control group, numeric increase was observed in the number of coliforms, Enterobacriaceae and lactobacillus counts in first group but this was not statistically important. The increase in coliforms and Enterobacteriaceae counts was nearly 2 log while this was 1 log for lactobacillus counts. Interestingly, dietary restriction + β-glucan administration had no significant influence on the increase of defined bacterial groups. The results of the present study showed that orally administration of the β-glucan, widely used as prebiotic, has the potential to modify faeces microbiota in rat model. Oral Yolla Uygulanan β-glukan ve Diyet Kısıtlamasının Ratların Fekal Mikroflorasına Etkisi Özet Bu çalışmanın amacı oral yolla verilen β-glukan ve/veya diyet kısıtlamasının rat feçesindeki Lactobacillus spp., koliform, Enterobacteriaceae ve enterokok sayıları üzerine etkisini ortaya koymaktır. Bu amaçla ratlar üç deneysel gruba ayrıldı: i) birinci grup 6 ay süresince normal diyetle beslenen ve son 14 gün oral yolla β-glukan (20 mg/kg, canlı ağırlığa) verilen hayvanlar ii) ikinci grup 6 ay boyunca diyet kısıtlaması uygulanan ve ilk grupla aynı şekilde β-glukan verilen hayvanlar iii) yalnızca ad libitum beslenen kontrol grubu ratlardan oluşmaktadır. Kontrol grubu ile karşılaştırıldığında, ilk grupta koliform, Enterobacteriaceae ve laktobasil sayılarında artış gözlendi, fakat bu artış istatistiksel olarak önemli değildi. Koliform ve Enterobacteriaceae sayılarındaki artış yaklaşık 2 log iken, laktobasil sayılarında bu artış 1 log idi. İlginç olarak diyet kısıtlaması ile birlikte β-glukan uygulaması adı geçen bakterilerin artışında önemli bir etki oluşturmadı. Mevcut çalışmanın sonuçları, prebiyotik olarak geniş kullanım alanı bulunan β-glukan'ın oral yolla takviyesinin rat modelinde dışkıdaki mikroorganizmaları modifiye etme potansiyeline sahip olduğunu gösterdi.
