“…The physical and chemical location of polysaccharides in the plant cell wall have a large influence on the physico-chemical properties of cell wall polysaccharides and consequently their action in the gastrointestinal tract (Bach-Knudsen, 2001). According to Urriola et al (2013), the main physico-chemical properties that impact animal nutrition include: solubility, water holding capacity, viscosity and fermentability.…”

“…Water holding capacity reflects the ability of a fiber source to incorporate water within its matrix (Bach-Knudsen, 2001). The morphological structure and composition of the fiber have a main effect in the strength of binding and the amount of water bound to the fiber 7 (Urriola et. al, 2013).…”

“…The bacterial population in the large intestine is responsible for the fermentation of dietary residues that escape digestion in the small intestine ( Figure 1). The products of fermentation of DF are short chain fatty acids (SCFA), which are absorbed into the portal 10 vein by passive diffusion (Urriola et al, 2013) and used as substrate for intestinal cell growth and renewal, or excreted in feces. According to Anguita et al (2006), energy absorbed as SCFA account for 67% to 74% of the total energy absorbed in the hindgut of pigs fed high fiber diets and the contribution of absorbed SCFA to the total available energy in pigs ranges from 7.1% to 17.6%.…”

This study evaluated the effect of xylanase supplementation (with or without), feeding method (dry or liquid), and feedstuff (corn distiller's dried grains with solubles [DDGS] or wheat middlings) on apparent total tract digestibility (ATTD) and apparent ileal digestibility (AID) of GE and nutrients, intestinal morphology, ileal and cecal pH, and VFA concentrations. Sixty-four growing pigs (25.87 ± 0.38kg initial BW) were blocked by BW and sex and randomly assigned to 8 dietary treatments. Within each feedstuff, diets were fed either liquid or dry, without or with xylanase (24,000 birch xylan units/kg feed), for 16 d. Diets contained 3.32 and 3.19 Mcal/kg ME for DDGS- and wheat middlings-based diets, respectively. Pigs were fed restricted at 3 times maintenance ME requirements. Liquid diets were prepared by steeping DDGS or wheat middlings with water (1:3, wt/vol) with or without xylanase for 24 h followed by mixing with a basal ingredient mixture and water to achieve a final ratio of 1:2.5 (wt/vol). During steeping of wheat middlings, some fiber degradation occurred. When xylanase was added in dry wheat middlings diets, AID of GE ( < 0.10) and NDF ( < 0.05) increased compared with dry wheat middlings diets without xylanase (64.50 vs. 54.67% and 52.88 vs. 31.69%, respectively), but supplementation of xylanase did not impact AID of GE and NDF when liquid wheat middlings diets were fed. Xylanase in liquid DDGS diets increased ( < 0.05) the AID of NDF compared with liquid DDGS diets without xylanase, but xylanase did not affect AID of NDF in dry DDGS diets. Xylanase in wheat middlings diets improved ( < 0.05) ATTD of GE and N compared with wheat middlings diets without xylanase (80.37 vs. 78.07% and 80.23 vs. 77.94%, respectively). However, there was no effect of xylanase in DDGS diets. Pigs fed DDGS diets had greater concentrations of butyrate in the cecum ( = 0.001) than pigs fed wheat middlings diets (27.6 vs. 20.4 mmol/L). Pigs fed DDGS diets with xylanase had deeper crypts ( < 0.05) in the jejunum than pigs fed DDGS diets without xylanase (98.20 vs. 86.16 μm), but xylanase had no effect in pigs fed wheat middlings diets. Results suggest that liquid feeding and xylanase supplementation had limited potential to enhance nutrient digestibility in pigs fed DDGS-based diets. However, xylanase supplementation in dry wheat middlings-based diets improved the AID of NDF and ATTD of GE and N, but liquid feeding as pretreatment did not further enhance the nutritional value of wheat middlings-based diets.

“…As an adaptation to dietary variation, pigs change their gastrointestinal structure, and enzyme and microbiology activity (Urriola et al 2013). In the same way, González et al (2003) reported heavier gastrointestinal tracts in pigs fed SP leaves.…”

“…Sundrum (2005) has reported that certain diets may increase the IMF of pork without affecting carcass BFT. Lower dietary CP and lysine concentrations have been associated with higher IMF in pork (Sundrum et al 2011;Apple 2013;Urriola et al 2013;Maeda et al 2014). Wu (1980) reported that N and ash concentrations of meat from pigs fed basal diets supplemented with sweet potato chips (0, 1% and 2% of BW) decreased, while ether extract and energy did not change.…”

The partial replacement of a commercial concentrate at 10-20% and 15-30% (the first percentage of each dietary treatment corresponded to weeks 1-3 and the second to weeks 4-7 of the experiment, respectively) by sweet potato meal (SPM; 70% foliage: 30% roots) was evaluated for growth performance, carcass yield, instrumental and sensory pork quality using 36 commercial crossbred pigs (56.8 ± 1.3 kg initial body weight). Three dietary treatments were compared in a randomized complete block design. Most growth, carcass traits and pork quality variables were not affected by the SPM inclusion. Growth performance averaged 868 g/day and feed efficiency 0.24 kg/kg. However, feed intake increased 2.2% (P = 0.04) in pigs fed the 10-20% SPM diets, in a similar order of magnitude as the decrease in dietary energy. Despite an increase in gastrointestinal tract as a percent of hot carcass weight (+14.7%) (P = 0.03) with SPM inclusion, carcass yield averaged 69.4%. Conversely, decreases in loin yield (-4.2%) (P = 0.05), backfat thickness (-6.0%) (P < 0.01) and pork tenderness (-13%) (P = 0.02) were observed with 15-30% SPM inclusion. Results suggest that up to 20% SPM inclusion is a viable feed strategy for finishing pigs, easily replicable in small farm settings. © 2016 Japanese Society of Animal Science.
