Twenty gilts with an initial body weight of 30.6\u2005\u00b1\u20050.2 kg (n\u2005=\u20055 per dietary treatment) were fitted with t-cannulae in the medial jejunum and terminal ileum, housed individually, and randomly assigned to one of four dietary treatments: low-fiber control (LF) with 10.4% total dietary fiber (TDF), 30% corn bran high-fiber control (HF; 26.4% TDF), HF\u2005+\u2005100 mg xylanase\/kg (XY; Econase XT 25P; AB Vista, Marlborough, UK), and HF\u2005+\u200550 mg arabinoxylan-oligosaccharide\/kg (AX). Gilts were limit fed for three 17 d periods (P1, P2, P3); each included 5 d adaptation, 2 d fecal collection, 3 d ileal collection, 3 d jejunal collection, and 4 d related rate of passage study. Data were analyzed as repeated measures using a linear mixed model with surgery date as a random effect, and dietary treatment, period, and their interaction as fixed effects. Jejunal and ileal digesta viscosity did not differ among dietary treatments or periods (P\u2005&amp;gt;\u20050.10). There was a dietary treatment \u00d7 period interaction for the apparent jejunal digestibility (AJD) of dry matter (DM), gross energy (GE), insoluble dietary fiber (IDF), neutral detergent fiber (NDF), total arabinoxylan (T-AX), total non-starch polysaccharide (T-NSP), and TDF (P\u2264 0.05). In P1, LF had the greatest AJD of DM (15.5%), and relative to HF and AX, XY decreased it (9.3%, 10.1 %, and 6.3%, respectively). In P2, the AJD of DM in XY was greater than HF (11.7% vs. 9.1%) but did not differ from AX (10.5%). Relative to HF, in P3, XY increased AJD of DM (11.7 vs 15.3%), and AX decreased it (7.2%). For the AJD of NDF, AX performed intermediately in P1; in P2, relative to HF, XY, and AX increased the AJD of NDF (8.4%, 13.1%, and 11.7%, respectively), and in P3, XY, and LF did not differ (13.6 vs. 14.4%). A similar response was observed for the AJD of IDF and TDF, except for XY having the greatest AJD of IDF, T-AX, T-NSP, and TDF in P3 (P\u2005&amp;lt;\u20050.05). Compared to LF, irrespective of period, HF decreased the apparent ileal digestibility (AID) and apparent total tract digestibility (ATTD) of IDF, TDF, and NDF (P\u2005&amp;lt;\u20050.05). Relative to HF, XY partially mitigated this effect, improving the AID and ATTD of TDF, IDF, and NDF (P\u2005&amp;lt;\u20050.05). Increased corn-based fiber decreased nutrient digestibility, but XY partially mitigated that effect in the small intestine through enhanced fiber digestibility when given sufficient adaptation time.<\/jats:p>","DOI":"10.1093\/jas\/skad378","type":"journal-article","created":{"date-parts":[[2023,11,22]],"date-time":"2023-11-22T17:26:17Z","timestamp":1700673977000},"source":"Crossref","is-referenced-by-count":8,"title":["Unveiling the influence of adaptation time on xylanase and arabinoxylan-oligosaccharide efficacy: a study on nutrient digestibility, viscosity, and scanning electron microscopy in the small and large intestine of growing pigs fed insoluble fiber"],"prefix":"10.1093","volume":"102","author":[{"given":"Amy L","family":"Petry","sequence":"first","affiliation":[{"name":"Department of Animal Science, Iowa State University , Ames, IA 50011 , USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nichole F","family":"Huntley","sequence":"additional","affiliation":[{"name":"Department of Animal Science, Iowa State University , Ames, IA 50011 , USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael R","family":"Bedford","sequence":"additional","affiliation":[{"name":"AB Vista Feed Ingredients , Marlborough, Wiltshire SN8 4AN , United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1672-5116","authenticated-orcid":false,"given":"John F","family":"Patience","sequence":"additional","affiliation":[{"name":"Department of Animal Science, Iowa State University , Ames, IA 50011 , USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2023,11,22]]},"reference":[{"key":"2024011116165682700_CIT0001","doi-asserted-by":"crossref","first-page":"338","DOI":"10.1093\/jas\/sky403","article-title":"Degradation of dietary fiber in the stomach, small intestine, and large intestine of growing pigs fed corn-or wheat-based diets without or with microbial xylanase","volume":"97","author":"Abelilla","year":"2019","journal-title":"J.
