“…In this study, the addition of xylanase improved ADG and G:F in pigs fed a diet high in insoluble corn-based fiber, but these improvements were not detectable until between days 14 and 27 of supplementation and were even greater after day 27. This is in agreement with Lan et al (2017) who reported that xylanase improved the ADG of nursery pigs fed a corn–soybean meal-based diet from 15 to 28 d of supplementation and improved ADG and G:F from day 29 to 42, and with Myers and Patience (2014) who reported a tendency for xylanase to improve ADG in nursery pigs fed corn-based diets from day 23 to 28 of supplementation. Likewise, Fang et al (2007 ) reported improvements in final BW, ADG, and feed efficiency of growing pigs fed a corn–soybean–rapeseed meal-based diet for 49 d. However, there is a paucity of studies that report improved pig performance when xylanase is supplemented in diets containing corn DDGS, and this has been largely attributed to the level of NDF within the diet, and the composition of corn arabinoxylan ( Jacela et al, 2010 ; Kerr et al, 2013 ).…”

The experimental objective was to investigate the impact of xylanase on the bioavailability of energy, oxidative status, and gut function of growing pigs fed a diet high in insoluble fiber and given a longer adaptation time than typically reported. Three replicates of 20 gilts with an initial body weight (BW) of 25.43 ± 0.88 kg were blocked by BW, individually housed, and randomly assigned to 1 of 4 dietary treatments: a low-fiber control (LF) with 7.5% neutral detergent fiber (NDF), a 30% corn bran without solubles high-fiber control (HF; 21.9% NDF), HF + 100 mg/kg xylanase (HF+XY; Econase XT 25P), and HF + 50 mg/kg arabinoxylan-oligosaccharide (HF+AX). Gilts were fed ad libitum for 36 d across 2 dietary phases. Pigs and feeders were weighed on d 0, 14, 27 and 36. On d 36, pigs were housed in metabolism crates for a 10-d period, limit fed (80% of average ad libitum intake) and feces and urine were collected the last 72 h to determine digestible energy (DE) and metabolizable energy (ME). On d 46, serum and ileal and colonic tissue were collected. Data were analyzed as a linear mixed model with block and replication as random effects, and treatment, time, and treatment × time as fixed effects. There was a significant treatment × time interaction for BW, average daily gain (ADG), and gain to feed (G:F; P<0.001). By design, BW at d 0 did not differ, at d 14 pigs fed LF were 3.5% heavier, and pigs fed HF+XY, when compared to HF, were 4% and 4.2% heavier at d 27 and d 36, respectively (P <0.001). From d 14 to 27 and d 27 to 36, when compared to HF, HF+XY improved ADG by 12.4% and 10.7% and G:F by 13.8% and 8.8%, respectively (P<0.05). Compared to LF, HF decreased DE and ME by 0.51 and 0.42 Mcal/kg, respectively, but xylanase partially mitigated that effect increasing DE and ME by 0.15 and 0.12 Mcal/kg, over HF, respectively (P<0.05). Pigs fed HF+XY had increased total antioxidant capacity in the serum and ileum (P<0.05) and tended to have less circulating malondialdehyde (P=0.098). Pigs fed LF had increased ileal villus height, and HF+XY and HF+AX had shallower intestinal crypts (P<0.001). Pigs fed HF+XY had increased ileal messenger ribonucleic acid abundance of claudin 4 and occludin (P<0.05). Xylanase, but not AX, improved the growth performance of pigs fed insoluble corn-based fiber. This was likely a result of the observed increase in ME, improved antioxidant capacity and enhanced gut barrier integrity, but it may require increased adaptation time to elicit this response.

“…This implies that CE can promote protein deposition in piglets when protein metabolises while maintaining decomposition levels across treatments. Urea is the main N-containing bi-product of amino acid catabolism and has a strong linear relationship to the PUN concentration [26]. Compared with CON, piglets fed with CE had increases in urea circulating AA in the plasma and also had the highest urea content.…”

The purpose of this study was to investigate the effects of citrus extract (CE) on plasma free amino acids, intestinal morphology and enzymes activity, fecal nitrogen and phosphorus emissions in piglets. The experiment was performed on 144 weaned piglets (Duroc × Landrace × Large White) divided into three groups. Control (CON), fed a basic diet; Antibiotic (ANTI), fed a basic diet supplemented with 75 g/t chlortetracycline; Citrus extract (CE), fed a basic diet supplemented with 300 mL/t CE. The albumin content of the CE group was significantly higher than the CON group. Compared with the CON and ANTI groups, the CE group had increased concentrations of plasma total essential amino acids and threonine. Compared with the CON group, CE increased the α-aminoadipic acid concentration, while compared with ANTI group, it increased the 3-methylhistidine concentration. Compared with the CON group, the crypt depth of duodenum, jejunum and ileum decreased, and the ratio of villus height to crypt depth of ileum increased in the ANTI and CE groups. CE increased the activity of alkaline phosphatase and lipase in duodenum, and the activity of alkaline phosphatase and trypsin in jejunum. In brief, CE improved the absorption and utilization of nitrogen, intestinal morphology and digestive enzymes activity.

Soaking the cereal fraction of a liquid diet prior to feeding (C soak), and/or carbohydrase enzyme supplementation (ENZ) are likely to modulate both feed and intestinal microbial populations and improve feed efficiency (FE) in pigs. To test this hypothesis, a total of 392 grow-finisher pigs (~33.4 kg, 7 pigs/pen) were randomly allocated to 4 treatments in a 2 × 2 factorial arrangement for 70 days as follows: (1) fresh liquid feed (Fresh); (2) Cereal soaked liquid feed (Soak); (3) Fresh + ENZ and (4) Soak + ENZ. An interaction between ENZ and C soak was found for average daily gain (ADG) during the growing phase (day 0 to 21; P < 0.05) where pigs fed the Soak + ENZ diet had higher ADG than pigs fed the Fresh + ENZ diet. No treatment effect was found for ADG thereafter. Enzyme supplementation increased total tract nutrient digestibility (P < 0.05) and reduced caecal VFA concentrations (P < 0.05) but did not improve pig growth or FE. Both C soak and ENZ modulated intestinal microbiota composition; increasing abundance of bacterial taxa that were negatively correlated with pig growth and reducing abundance of taxa positively correlated with pig growth and caecal butyrate concentration. In conclusion, both strategies (C soak and ENZ) improved nutrient digestibility in pigs and modulated intestinal microbiota composition.
