“…1,16,17 The intake of high dietary ber has been reported to inuence energy metabolism, nutrient utilization, and subsequently results in a reduction in the performance of monogastric animals, especially pigs. [18][19][20] Recent ndings indicated that dietary ber can prevent intestinal diseases such as constipation, diarrhea, bowel diseases, and improve intestinal health in both humans and animal subjects. 10,21,22 Different dietary ber has benecial roles in gut microbial composition and function.…”

“…Studies in pig nutrition have indicated the significant role played by diets in changing the histological appearance of the gut [42]. The findings of this study showed that high fibre RBN diet had beneficial effects on gut mucosa with longer ileal villi compared to pigs offered the basal diet.…”

“…In growing pigs, strategic co-product feeding primarily involves targeting maximal fermentable fibre (Anguita et al, 2006;Gutierrez et al, 2013;Iyayi & Odeola, 2015) to offset fibre-induced nutrient and digestive metabolic energy wastage (Noblet & Le Goff., 2001). Emerging evidence supports the consideration of dietary polysaccharides that promote gut health (Aumiller et al, 2015;Agyekum & Nyachoti, 2017;Celi et al, 2018). Prebiotic fibre includes resistant starch, galacto and fructo oligosaccharides, mixedlinked β-glucans and soluble arabinoxylans (Aumiller et al, 2015).…”

“…In monogastrics, exogenous polysaccharide degrading enzymes potentially improve the nutritional efficacy of complexly fibrous diets through substrate-dependent iNSP depolymerization to randomly polydisperse oligosaccharides (Choct et al, 2006). However, in pigs, current enzymes seem impotent, particularly on maize-soybean diets (Willamil et al, 2012;Agyekum & Nyachoti, 2017), more so when the diets contain substantial co-product fibre (Kerr & Shurson, 2013).…”

“…Mature sow rectal faecal microbiota inoculum are employed in batch fermentation of washed fibrous extracts from pepsin (gastric) + pancreatin (small intestinal) feed digestion (Bindelle et al, 2007), from which total SCFA and cumulative gas jointly predict insoluble fibre fermentability (Bindelle et al, 2007;Jonathan et al, 2012). Endpoint SCFA and microbiota (Verbeke et al, 2015;Agyekum & Nyachoti, 2017) and the gas production kinetics (France et al, 1993;Groot et al, 1996) provide important insights into gut functionality. With wider testing, the approach might provide a practical evaluative tool for optimal co-product feeding.…”

The study examined the effects of botanical factors and fermentation-based, high-level dilution of coproduct feeds in maize-soybean growing-pig diets on enzymatic insoluble fibre hydrolysis and fermentation. Feed insoluble fibre residues that were recovered after pepsin-pancreatin digestion were subjected to Roxazyme ® G2 (Roxazyme) versus Viscozyme L ® V2010 (control) hydrolysis, and to 64-hour fermentation using pig faecal inoculum. The control diet was a 13 MJ metabolizable energy, 141 g total dietary fibre/kg dry matter maize-meal/hominy chop-soybean diet, which was diluted with maize cob, soybean hulls, barley brewer's grains, lucerne hay or wheat bran in 12 MJ metabolizable energy, 246 g total dietary fibre/kg dry matter iso-nutrient, single co-product test diets. Fermentable insoluble fibre was employed in a computerized iterative selection of ingredients in two iso-nutrient 11 MJ metabolizable energy 319 total dietary fibre/kg dry matter mixed fibre test diets for maximal contrast (high (HF) versus low (LF)) in fermentability. Insoluble fibre extractive pepsin-pancreatin digestibility differed between feed ingredients, and the single co-product test diets, and between the HF and LF mixed co-product diets. Fibre digestibility depended on both the origin and enzyme, with interaction, whereby carbohydrases expressed similar low (0.04-0.05) insoluble fibre digestibility for maize cob, moderate (0.12) digestibility for wheat bran and brewer's grain, with inferior Roxazyme G2 digestibility for maize hominy chop (0.02 vs 0.10) and meal (0.04 vs 0.16), dehulled soybean meal (0.02 vs 0.17), lucerne hay (0.08 vs 0.18), and soybean hulls (0.05 vs 0.33). Co-product-enzyme affinities were expressed in single fibre diets. Low Roxazyme-basal fibre affinity limited its comparative single co-product (0.03-0.07 vs 0.16-0.22) HF (0.07 vs 0.17) and LF (0.4 vs 0.20) dietary fibre digestibility. Screening for HF/LF did not affect enzymatic digestion, though enzyme combination increased HF, but not LF digestibility. Gas and short chain fatty acid production predicted fermentability proportionately in the declining order of dehulled soybean ≥ maize ≥ soy hulls ≥ maize hominy chop > wheat bran >lucerne hay ≥ brewer's grain = maize cob. Induced HF and LF contrast was significant. Co-product fibre enrichment decreased fermentability for all except the soy hull and HF diets. Cereal fibre yielded proportionately less acetate, with more propionate and butyrate, and a greater butyrate shift for maize fibre. The HF fibre induced more ACE and less butyrate. Biomarkers of deleterious proteolytic fermentation were high for lucerne (isobutyrate) and soy hulls (iso-valerate). In conclusion, high-level and fermentation based co-product feed dilution into maize-soybean growing pig diets altered enzymatic insoluble fibre hydrolysis and fermentation in relation to botanical origin. Roxazyme expressed weak hydrolytic potency on maize and soybean insoluble fibre.
