Abstract
The present study determined the effects of dietary xylo-oligosaccharides (XOS) supplementation on the morphology of jejunum and ileum epithelium, fecal microbiota composition, metabolic activity, and expression of genes related to colon barrier function. A total of 150 piglets were randomly assigned to one of five groups: a blank control group (receiving a basal diet), three XOS groups (receiving the basal diet supplemented with 100, 250, and 500 g/t XOS, respectively), as well as a positive control group, used as a matter of comparison, that received the basal diet supplemented with 0.04 kg/t virginiamycin, 0.2 kg/t colistin, and 3,000 mg/kg ZnO. The trial was carried out for 56 days. The results showed that the lowest dose tested (100 g/t XOS) increased (P < 0.05) the ileal villus height, the relative amount of Lactobacillus and Bifidobacterium spp., and the concentration of acetic acid and short-chain fatty acid in feces when compared with the blank control group. In conclusion, dietary 100 g/t XOS supplementation modifies the intestinal ecosystem in weaned piglets in an apparently overall beneficial way.

Dietary supplementation with Bacillus subtilis and xylo-oligosaccharides improves growth performance and intestinal morphology and alters intestinal microbiota and metabolites in weaned piglets.

Abstract
The present study was conducted to investigate the effects of dietary supplementation with Bacillus subtilis (BS) and xylo-oligosaccharides (XOS) on growth performance, intestinal morphology, intestinal microbial community, and metabolites of weaned piglets. One hundred and twenty-eight piglets were randomly allocated to one of four groups, including a control group (basal diet), BS group (basal diet + 500 g t-1 BS), XOS group (basal diet + 250 g t-1 XOS), and BS + XOS group (basal diet + 500 g t-1 BS + 250 g t-1 XOS). Dietary BS and XOS were mixed with the basal diet. All groups had eight replicates with four piglets per replicate. The experiment lasted for 42 days. The results showed that dietary XOS supplementation increased the ADFI and ADG, while decreasing the F/G. Dietary BS or XOS supplementation improved the intestinal morphology of weaned piglets by increasing the villus height and the ratio of villus height to crypt depth in the ileum. In addition, dietary XOS supplementation increased the concentrations of butyrate in the ileum and tryptamine and spermidine in the colon, while decreasing the concentration of indole in the colon compared with the control group. Dietary BS supplementation increased the colonic concentrations of butyrate, tryptamine, and cadaverine, while decreasing the concentration of skatole compared with the control group. The LEfSe analysis identified 16 biomarkers in the ileum of the BS group. The intestinal microbiota alterations of weaned piglets indicated that dietary BS or XOS supplementation could improve intestinal health by increasing the gut microbial diversity and altering the relative abundances of different bacterial species. Moreover, Spearman's correlation analysis revealed the potential link between gut microbiota alterations and metabolite changes of weaned piglets. These findings suggest that dietary XOS supplementation could alone improve the growth performance, while dietary BS or XOS and BS with XOS supplementation could influence intestinal health by altering the intestinal morphology, microbial community, and metabolites of weaned piglets. Meanwhile, there were interactions between BS and XOS in intestinal metabolites.

Abstract
Gut microbiota positively contribute to livestock nutrition and metabolism. The manipulation of these microbes may improve animal health. Some feed additives improve livestock health and metabolism by regulating gut microbiota composition and activity. We fed hybrid pigs diets supplemented with 0% (control), 5% (treat 1), 10% (treat 2), or 15% (treat 3) fermented Mao-tai lees (FML) for 90 days. Short-chain fatty acids (SCFAs), bioamines, and microbial communities found in colonic contents were analyzed to investigate microbiota composition and metabolic profiles. Concentrations of straight-chain fatty acids (e.g., acetate, propionate, and butyrate) and tyramine increased with FML supplementation content. Contrary to the minor effects of 5% and 10% FML on gut microbiota, 15% FML influenced beta diversity (Jaccard or Bray-Curtis dissimilarity) but not alpha diversity (number of operational taxonomic units and Shannon diversity) of pig gut microbial communities compared to the control group. Notably, 15% FML animals were characterized by a higher abundance of potentially beneficial bacteria (Lactobacillus and Akkermansia) but lower abundances of potential pathogens (Escherichia). Numerous genes associated with metabolism (e.g., starch, sucrose, and sulfur-compounds metabolism) showed a higher relative abundance in the 15% FML than in the control group. Additionally, most Phascolarctobacterium, Treponema, Prevotella, and Faecalibacterium bacterial markers in the 15% FML group were positively correlated with straight-chain fatty acid concentrations, suggesting that these bacteria are likely associated with SCFA production. Taken together, our findings demonstrate the beneficial effects of 15% FML on fermentation of undigested compounds and gut microbiota composition in the colon. Thus, 15% FML supplementation in pig feed may possibly represent a way to optimize pig colon health for livestock farming.

Fermentation of xylo-oligosaccharides by Bifidobacterium adolescentis DSMZ 18350: kinetics, metabolism, and β-xylosidase activities. Appl Microbiol Biotechnol 2012; 97:3109-17. [PMID: 23099913 DOI: 10.1007/s00253-012-4509-y] [Citation(s) in RCA: 39] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2012] [Revised: 10/04/2012] [Accepted: 10/09/2012] [Indexed: 12/21/2022]
Abstract
Xylo-oligosaccharides (XOS) are sugar oligomers of β-1,4-linked xylopyranosyl moieties which exert bifidogenic effect and are increasingly used as prebiotics. The kinetics and the metabolism of Bifidobacterium adolescentis DSMZ 18350 growing on XOS and xylose were investigated. The growth rate was higher on XOS, but greater biomass yield was attained on xylose. Unlike other prebiotics, XOS oligomers were utilized simultaneously, regardless of their chain length. Throughout XOS utilization, xylose concentration slightly increased, being not neatly consumed and remaining unfermented. During growth on XOS, β-xylosidase activity was present in the cytosol, but it occurred in the supernatant as well. A β-1,4-xylolytic enzyme was purified from the supernatant of XOS cultures. The enzyme, a homotetramer of a 39-kDa single protein, was capable of complete XOS hydrolysis and exhibited maximum activity at pH 6.0 and 55 °C. Based on the molecular weight, the protein can be ascribable to the product of the gene BAD_1527, the activity of which has been inferred as an endo-β-1,4-xylanase, but has not been characterized so far. This β-1,4-xylolytic enzyme, found to be active in the cultural supernatant, gives a reason for the never explained accumulation of the monosaccharides in the media of bifidobacterial cultures growing on XOS, without excluding the major role of the intracellular hydrolysis of the imported oligomers.

Abstract
The effect of prebiotic xylooligosaccharides (XOS) on the growth performance and digestive enzyme activities of the allogynogenetic crucian carp, Carassius auratus gibelio, was investigated. XOS was added to fish basal semi-purified diets at three concentrations by dry feed weight: diet 1, 50 mg kg(-1); diet 2, 100 mg kg(-1); diet 3, 200 mg kg(-1), respectively. Twelve aquaria (n = 20) with three replicates for each treatment group (diets 1-3) and control treated without XOS were used. Weights of all collected carp from each aquarium were determined at the initial phase and at the end of the experiment, and the carp survival was also determined by counting the individuals in each aquarium. After 45 days, there were significant differences (P < 0.05) in the relative gain rate (RGR), and daily weight gain (DWG) of diets 1-3 were compared with the control. However, the survival rate was not affected (P > 0.05) by the dietary treatments. For enzymatic analysis, dissection produced a crude mixture of intestine and hepatopancreas of each segment to measure. The protease activity in the intestine and hepatopancreas content of fish in diet 2 (487.37 +/- 20.58 U g(-1) and 20.52 +/- 1.93 U g(-1)) were significantly different (P < 0.05) from that in the control (428.13 +/- 23.26 U g(-1) and 12.81 +/- 1.52 U g(-1)) and diet 3 (428.00 +/- 23.78 U g(-1) and 14.04 +/- 1.59 U g(-1)). Amylase activity in the intestine was significantly higher for diet 2 compared to diet 1 and the control. As for amylase in the hepatopancreas, assays showed higher activity in diet 2 (P < 0.05) compared to the rest.

Abstract
Enterobacterial repetitive intergenic consensus-PCR (ERIC-PCR) is a molecular biological technology that can be used to study microbial community diversity and dynamics. In many reports, investigations of microbial diversity from environmental samples were based on the agarose gel electrophoresis (AGE) patterns of ERIC-PCR amplified products. This is not a sound practice, since bands with identical positions can contain different sequences; thus, this practice could possibly exaggerate the similarities or diversities among samples. To mitigate this issue, we employed a denaturing gradient gel electrophoresis (DGGE) strategy to explore DNA bands with the same size, between ERIC-PCR profiles of samples. DPS software was used with Shannon-Wiener diversity index (H') to analyze ERIC-PCR fingerprint profiles. H' revealed that the microbial community diversity at DGGE was higher than with AGE. The results of this study suggest that the ERIC-PCR assays with DGGE can provide a better assessment of electrophoresis pattern with regards to the structure of an intestinal microbial community.
