“…In this study, a combination of XB was used because they target arabinoxylans, which are abundant in most of grains and co-products, followed by cellulose and β-glucans (De Vries et al, 2012;Jakobsen et al, 2015). Analyzed chemical composition of experimental diets is shown in Table 2.…”

“…Liquid feeding systems allow feedstuffs to be soaked in water, which provides a favorable environment for endogenous enzymes present in feed ingredients and added exogenous enzymes to be activated for short or prolonged periods allowing enzymatic digestion prior to feeding. Improved nutrient digestibility and volatile fatty acid (VFA) production have been reported in pigs fed liquid fermented feed with supplemental enzymes (Jakobsen et al, 2015). Optimally fermented liquid feed can improve gastrointestinal health by reducing the number of pathogens as reduced pH from fermentation prevents growth of harmful microorganism such as Escherichia coli and Salmonella (Brooks et al, 2001;Canibe and Jensen, 2012), improving growth performance (Missotten et al, 2010;Wiseman et al, 2017).…”

Fermenting high fiber ingredients such as distillers dried grains with solubles (DDGS) with feed enzymes may improve their feeding value. We investigated the effects of fermenting corn DDGS with a blend of β-glucanase and xylanases (XB) on growth performance, gut parameters, and apparent total tract digestibility (ATTD) of nutrients and energy in growing pigs. Dietary treatments were: (1) corn soybean meal-based diet + 30% DDGS (control), (2) control + XB without fermentation (XBNS), and (3) control + DDGS fermented with XB (16% DM) for 3 to 10 d at 40 °C (XBS). Target activities in XB were 1,050 and 5,500 U/g of DDGS for XB, respectively. Diets contained phytase at 750 FTU/kg. Feed samples were taken during fermentation and at feeding for analysis of pH and organic acids. A total of 144 pigs (25 ± 1.0 kg BW) were assigned to pens (three barrows and three gilts) and allocated to the three diets in a two-phase feeding program (3 wk/phase). Diets were fed on ad libitum and were delivered by a computer-controlled liquid feeding system at a feed to water ratio of 1:4, four times per day. Pigs had free access to water. Fecal samples were taken in the final 3 d of phase 2 to determine ATTD using TiO2 marker method and one pig per pen was euthanized for gastrointestinal (GIT) measurements. The pH of diets at feeding time was lower (P < 0.01) for XBS (4.72) compared with control (5.45) and XBNS (5.45). Pigs fed XBNS had higher (P = 0.04) ADG than control in phase 1. In phase 2 and the overall (weeks 0 to 6), ADG and final BW were higher (P = 0.01) for XBNS than XBS but were not different (P > 0.05) from control. There were no diet effects (P > 0.05) on ADFI. Feed to gain (FCR) for XBNS (1.68) and XBS pigs (1.69) was better (P < 0.01) than for control pigs (1.78) in phase 1. There were no diet effects (P > 0.05) on FCR in phase 2 or in the overall. Pigs fed XBNS had lower (P < 0.01) ATTD of CP than control and XBS-fed pigs. Although not different (P > 0.05) from control, pigs fed XBNS had lower (P < 0.05) jejunal crypt depth and ATTD of gross energy than pigs fed XBS. In conclusion, treating corn DDGS with XB with or without liquid fermentation improved feed efficiency in phase 1, suggesting degradation of dietary fibrous components that may limit nutrient utilization in younger pigs. However, these benefits were not observed in phase 2.

“…Fermented feed has also been reported to reduce the counts of Enterobacteriaceae along the entire gastrointestinal tract (Canibe and Jensen 2003). The fermentation of DDGS by probiotics can degrade the crude fiber component and non-starch polysaccharides in distillers' grains (Jakobsen et al 2015). Organic acids, such as lactic acid, are produced by probiotics during the process of fermentation and a low-pH environment can also mitigate the mold production in DDGS.…”

The objective of this study was to investigate pig fed by Bacillus coagulans-fermented distillers' dried grains with solubles (DDGS) on the faecal microbial composition and diversity using 454 pyrosequencing. Healthy crossbred (Duroc×York-shire×Landrace) growing and fattening pigs (n=48), with an average initial body weight of 65 kg, were divided into two groups (24 replicates per group; four pens per group; six pigs per pen), and given either DDGS feed as the control, or B. coagulans-fermented DDGS feed as the treatment. Faecal samples were collected on day 0, 7, 14, 21, and 28. DNA was extracted, and the V3-V6 region of the 16S rRNA gene was amplified. The fermented DDGS feed affected the relative abundance of bacteria populations at the phylum, genus, and species levels. At the genus level, the consumption of fermented DDGS feed led to higher relative abundances of faecal Prevotella, Lactobacillus, Clostridium, Bifidobacterium, Roseburia, and Bacillus, and lower relative abundances of faecal Escherichia, Ruminococcus, Dialister, unclassified Lachnospiraceae, unclassified Ruminococcaceae, and unclassified Enterobacteriaceae than in the control. At the species level, the consumption of fermented DDGS feed led to higher relative abundances of faecal Prevotella sp., Lactobacillus johnsonii, Lactobacillus fermentum, Lactobacillus mucosae, Lactobacillus reuteri, Clostridium butyricum, Bifidobacterium sp., and Roseburia sp., and lower relative abundances of faecal Prevotella copri, Escherichia coli, Ruminococcus gnavus, Ruminococcus flavefaciens, and Dialister sp. than in the control. Principal coordinates analysis indicated a distinct separation in the faecal microbial communities of pigs that were fed the fermented and unfermented DDGS feed. Fermented DDGS feed significantly increased the average daily gain (ADG) of pigs, and significantly decreased the average daily feed intake (ADFI) of feed and feed/gain (F/G). Thus, our results demonstrate a beneficial shift in the faecal microbiota of pigs consuming fermented DDGS feed, with potential applications in livestock production.

“…Dried distillers grains with solubles of wheat origin (DDGS) was used as NSP source, because of the high NSP content and the expected high NSP digestibility. In pigs relatively high NSP digestibility of DGGS are reported (Jakobsen et al, 2015;Tanghe et al, 2015) The NSP diet was a mixture of 70% of the starch diet with 30% DGGS (Table 5.1). In order to keep crude protein and fat content similar between diets and based on the predicted protein and fat content of DDGS, the starch diet was formulated to have the same protein and fat content as NSP diet.…”
