Forty-four Dorper\u2005\u00d7\u2005Santa In\u00eas male lambs [initial body weight (BW)\u2005=\u200524.2\u2005\u00b1\u20051.0 kg and age\u2005=\u200582.1\u2005\u00b1\u20051.0 d] were assigned to a randomized complete block design. Treatments were arranged in a 2\u2005\u00d7\u20052 factorial design, in which factor 1 was 52 (52peNDF-F) or 104 g\/kg of peNDF-F (104peNDF-F), and factor 2 was diets with (N13) or without (N0) inclusion of 13 mg of narasin\/kg of dry matter (DM) (Zimprova; Elanco Animal Health, S\u00e3o Paulo, SP, Brazil). The experimental period lasted 112 d, and lambs were slaughtered on day 116. The data was analyzed using the MIXED Procedure of SAS, using lambs as experimental units. No peNDF-F\u2005\u00d7\u2005narasin inclusion interactions were detected (P\u2005\u2265\u20050.12) for any performance and carcass parameters evaluated herein. Lambs fed 104peNDF-F diets had greater (P\u2005\u2264\u20050.05) DM, organic matter, crude protein, NDF, ADF, and ether extract intake compared with lambs fed 52peNDF-F diets. This improvement in intake did not result in changes (P\u2005\u2265\u20050.51) in average daily gain and final BW between peNDF-F levels. Lambs fed 52peNDF-F had greater (P\u2005&amp;lt;\u20050.01) feed efficiency compared with lambs fed 104peNDF-F diets. Lambs fed 52peNDF-F diets had greater (P\u2005\u2264\u20050.03) body wall thickness and perirenal fat than lambs fed 104peNDF-F. Narasin inclusion did not impact (P\u2005\u2265\u20050.20) any performance parameters or intake. The inclusion of N13 in 52peNDF-F or 104peNDF-F diets tended to reduce (P\u2005&amp;lt;\u20050.01) the molar proportion of ruminal acetate and the acetate:propionate (Ac:Pr) ratio compared to N0, while increasing (P\u2005&amp;lt;\u20050.01) ruminal propionate. Lambs fed N13 diets had greater (P\u2005=\u20050.02) cecal propionate and lower (P\u2005\u2264\u20050.05) isobutyrate and Ac:Pr ratio compared to N0. Lambs fed 104peNDF-F diets exhibited an increased (P\u2005=\u20050.04) number of papillae per cm\u00b2 and reduced (P\u2005=\u20050.05) thickness of the keratinized layer of ruminal papillae compared to those fed 52peNDF-F diets. Including N13 increased (P\u2005\u2264\u20050.04) papillae height, surface area, and absorptive surface area per cm\u00b2 compared to lambs fed N0 diets. Overall, reducing peNDF-F altered digestive dynamics, while narasin promoted a shift in short-chain fatty acids profiles, and rumen papillae development in feedlot lambs fed high-concentrate diets.<\/jats:p>","DOI":"10.1093\/jas\/skaf235","type":"journal-article","created":{"date-parts":[[2025,7,17]],"date-time":"2025-07-17T10:05:15Z","timestamp":1752746715000},"source":"Crossref","is-referenced-by-count":2,"title":["Levels of physically effective neutral detergent fiber from forage and narasin inclusion: performance, carcass traits, meat quality, gastrointestinal fermentation, and rumen histology in feedlot lambs"],"prefix":"10.1093","volume":"103","author":[{"given":"Lairana Aline","family":"Sardinha","sequence":"first","affiliation":[{"name":"Department of Nutrition and Animal Production, University of S\u00e3o Paulo, FMVZ , Pirassununga, SP, 13635-000,","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4590-2898","authenticated-orcid":false,"given":"Rodrigo S","family":"Marques","sequence":"additional","affiliation":[{"name":"School of Animal Sciences, Virginia Polytechnic Institute and State University , Blacksburg, VA, 24061,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arnaldo Cintra","family":"Limede","sequence":"additional","affiliation":[{"name":"School of Animal Sciences, Virginia Polytechnic Institute and State University , Blacksburg, VA, 24061,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Let\u00edcia Carolina Bortolanza","family":"Soares","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Animal Production, University of S\u00e3o Paulo, FMVZ , Pirassununga, SP, 13635-000,","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fernando A A","family":"Cidrini","sequence":"additional","affiliation":[{"name":"School of Animal Sciences, Virginia Polytechnic Institute and State University , Blacksburg, VA, 24061,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ariany Faria","family":"de Toledo","sequence":"additional","affiliation":[{"name":"Department of Animal Science, \u201cLuiz de Queiroz\u201d College of Agriculture, University of S\u00e3o Paulo , Piracicaba, SP, 13418-900,","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer M","family":"Gasparina","sequence":"additional","affiliation":[{"name":"Department of Animal Science, \u201cLuiz de Queiroz\u201d College of Agriculture, University of S\u00e3o Paulo , Piracicaba, SP, 13418-900,","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rhaissa G","family":"de Assis","sequence":"additional","affiliation":[{"name":"Department of Animal Science, \u201cLuiz de Queiroz\u201d College of Agriculture, University of S\u00e3o Paulo , Piracicaba, SP, 13418-900,","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4961-3866","authenticated-orcid":false,"given":"Rodrigo Silva","family":"Goulart","sequence":"additional","affiliation":[{"name":"Animal Science Department, College of Animal Science and Food Engineering - University of Sao Paulo , Pirassununga, SP, 13635-900,","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Evandro Maia","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Department of Animal Science, \u201cLuiz de Queiroz\u201d College of Agriculture, University of S\u00e3o Paulo , Piracicaba, SP, 13418-900,","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandre Vaz","family":"Pires","sequence":"additional","affiliation":[{"name":"Department of Animal Science, \u201cLuiz de Queiroz\u201d College of Agriculture, University of S\u00e3o Paulo , Piracicaba, SP, 13418-900,","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel Montanher","family":"Polizel","sequence":"additional","affiliation":[{"name":"Department of Biology and Animal Science, S\u00e3o Paulo State University \u201cJulio de Mesquita Filho\u201d , Ilha Solteira, SP, 15385-000,","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2025,7,18]]},"reference":[{"key":"2025082505312401000_CIT0001","doi-asserted-by":"publisher","first-page":"269","DOI":"10.1016\/s0003-9861(63)80012-0","article-title":"Biosynthesis of branched-chain amino acids from branched-chain fatty acids by rumen bacteria","volume":"101","author":"Allison","year":"1963","journal-title":"Arch.
