Abstract
BACKGROUND Barley contains a relatively high concentration of the mixed-linkage (1 → 3) (1 → 4) β-glucan, which has been reported to be a functional food with prebiotic potential. In the current study we compared the properties of two neutral barley β-glucans, obtained from raw barley: raw barley β-glucan (RBG) and Lactobacillus plantarum dy-1-fermented barley (FBG). RESULTS Molecular characteristics revealed that the molecular weight of barley β-glucan decreased from 1.13 × 105 D to 6.35 × 104 D after fermentation. Fermentation also improved the water / oil holding capacity, solubility, and swelling capacity of barley β-glucan. Both RBG and FBG significantly improved the locomotive behavior of nematodes, thereby increasing their energy consumption and reducing fat deposition - the effect was more significant with FBG. These effects could potentially depend on nhr-49, TGF-daf-7 mediated pathways and so on, in which nhr-49 factor is particularly required. CONCLUSION These results suggested that fermentation may enhance in vitro physiological activities of barley β-glucan, thereby altering the effects on the lipid metabolism in vivo. © 2020 Society of Chemical Industry.

Abstract
The aim of this study was to evaluate the effects of oat beta-glucan supplementation on metabolic, physiological, immunological and nutritional variables in adult dogs. Fourteen dogs were fed a control diet or a diet supplemented with 1% beta-glucan during 71 days. Serum concentrations of glucose, total cholesterol and lipoprotein fractions, as well as plasma concentrations of peptide YY and ghrelin, were determined. In addition, coefficient of total tract apparent macronutrient digestibility (CTTAD), food intake and fecal output, score, and pH were evaluated. For evaluation of immunological variables, serum concentrations of interleukin-4 and interferon gamma were determined on days 0, 57 and 71, which corresponded to blood collection prior to beta-glucan supplementation, and at 7 and 14 days post first and second dose of vaccination (Pneumodog®, Merial, Campinas, Brazil), respectively. Animals fed the supplemented diet showed (P<0.05) lower serum concentrations of total cholesterol and low and very low density lipoproteins, lower coefficients of total tract apparent digestibility of dry matter, organic matter, mineral matter and ether extract, higher fecal output and lower fecal consistency, as well as a tendency (P = 0.07) of decreasing the coefficient of total tract apparent digestibility of crude protein. Moreover, the supplemented diet resulted in lower number of red blood cells, hematocrit percentage and hemoglobin concentration 21 days post-vaccination as well as lower serum concentration of interleukin-4 seven days post-vaccination (P<0.05). It is concluded that oat beta-glucan extract can be used as a dietary supplement for dogs at a dose of 10 g/kg of food, being effective in reducing blood concentrations of total cholesterol, LDL-c and VLDL-c as well as CTTAD of nutrients, demonstrating a potential to be used in the feeding of obese animals. In addition, by reducing the predominance of a Th2 response, oat beta-glucan can positively modulate the vaccine response of animals.

Abstract
This study investigates the effect of dietary supplementation of a β-glucanase and β-xylanase enzyme mix to barley based diets, at two different chemical compositions achieved through different agronomical conditions on growth performance, coefficient of apparent total tract digestibility (CATTD) of nutrients, selected faecal microbial populations and faecal scores in piglets. Sixty-four piglets (11.7 kg (SD 0.96)) housed in pens of two were assigned to one of four dietary treatments (n = 8). The dietary treatments were as follows: (T1) low quality barley diet, (T2) low quality barley diet containing a β-glucanase and β-xylanase enzyme supplement, (T3) high quality barley diet and (T4) high quality barley diet containing a β-glucanase and β-xylanase enzyme supplement. Piglets offered the low quality barley-based diet had a higher (p < .05) average daily gain (ADG) (0.73 vs. 0.69 kg, SEM 0.001), gain:feed (G:F) ratio (0.61 vs. 0.58 kg, SEM 0.011) and a higher CATTD (p < .001) of dry matter (DM), organic matter (OM), nitrogen (N), ash, gross energy (GE) and neutral detergent fibre (NDF) compared with piglets offered the high quality barley diet. Piglets offered the high quality barley-based diet had reduced faecal scores compared to piglets offered the low quality barley-based diet (2.44 vs. 2.57, SEM 0.036) (p < .05). There was a higher population of Lactobacillus spp. (11.6 vs. 10.5 log gene copy number/g faeces, SEM 0.177) (p < .001) and total volatile fatty acid (VFA) concentration (185 vs. 165 mmol/g faeces, SEM 5.658) (p < .001) in the faeces of piglets offered the high quality barley-based diet compared to piglets offered the low quality barley-based diet. The inclusion of a β-glucanase and β-xylanase enzyme complex had no effect on any variable measured. In conclusion, the higher quality barley-based diet showed beneficial effects on the faecal Lactobacillus spp. population and faecal scores of the piglets; however, the higher level of β-glucans in the diet decreased nutrient digestibility and subsequently decreased the performance.

Abstract
Cereal β-glucan may be detrimental in pig production because of negative effects on nutrient digestibility, but they may act as functional ingredients by stimulating the intestinal microbiota. This study primarily aimed to investigate relations between dietary β-glucan and nutrient digestibility, intestinal fermentation, and manure NH3 emission in weaned, growing, and finishing pigs. Effects of dietary xylose, NDF, and CP, and pig BW on animal responses were also evaluated. A meta-analytical approach, accounting for inter- and intraexperiment variations, was used to compute prediction models. Data from 26 studies including 107 different dietary treatments with appropriate dietary and physiological measurements were used to parameterize these models. Dietary β-glucan inclusion ranged from 0 to 6.7%. Increasing dietary β-glucan reduced apparent ileal (AID) and total tract digestibility (ATTD) of CP and energy (R(2) = 0.12 to 0.29; P < 0.05), whereas the ATTD of DM was reduced by 10% up to a threshold β-glucan of 3.5%, above which the response became asymptotic (R(2) = 0.34; P < 0.01). Increasing dietary NDF content decreased ATTD of DM and energy, and increasing xylose concentration reduced ATTD of energy and CP (R(2) = 0.24 to 0.85; P < 0.05). Broken-line model indicated that cecal total VFA and butyrate concentrations increased up to a threshold of 2.5 and 1.4% β-glucan in the diet, respectively, above which these responses became asymptotic (R(2) = 0.77 to 0.96; P < 0.05). Ileal butyrate was negatively and colonic iso-butyrate was positively linked to increasing β-glucan concentration (R(2) = 0.17 to 0.41; P < 0.05). Greater β-glucan concentration were negatively related (R(2) = 0.86; P < 0.01) to NH3 emission, indicating a reduction in NH3 emission by one-half with 6% β-glucan. Backward elimination analysis indicated that greater BW of pigs counteracted (P < 0.05) the negative effect of β-glucan on AID of CP and energy and ATTD of DM and CP. Pig BW also enhanced effects of β-glucan on cecal total VFA, colonic iso-butyrate, ileal butyrate, and NH3 emission (P < 0.05). Dietary CP potentiated (P < 0.01) the β-glucan effects on cecal total VFA, cecal butyrate, and colonic iso-butyrate. In conclusion, this study indicates that β-glucan can stimulate cecal butyrate and ameliorate manure NH3 emission, thereby decreasing nutrient digestibility. Because greater BW ameliorates β-glucan effects, finishing diets may be formulated to contain more β-glucan than weaner diets.
