Acacia gum with medium-to-high fermentability and low viscosity was increasingly included in diets to investigate its effect on apparent ileal digestibility (AID) and apparent total tract digestibility (ATTD) of nutrients, gross energy (GE), and standardized total tract digestibility (STTD) of P in growing pigs. A control diet (49% cornstarch; 18% bovine plasma protein) was formulated to measure basal EPL. Three additional diets were formulated to include 2.5%, 5.0%, or 7.5% acacia gum at the expense of cornstarch. Diets contained 16.1% to 17.4% CP and 0.31% to 0.33% total P (DM-basis). The four diets were fed to eight ileal-cannulated barrows (initial BW, 54.6 kg) for four 9 d periods in a double 4 \u00d7 4 Latin square. Apparent hindgut fermentation (AHF) was calculated as ATTD minus AID. Feeding increasing acacia gum quadratically affected (P &amp;lt; 0.05) AID of DM, GE, linearly decreased (P &amp;lt; 0.05) ATTD of DM, crude protein (CP), GE, digestible (DE) and predicted net energy (NE) value of diets, and linearly increased (P &amp;lt; 0.001) AHF of DM and GE. Increasing acacia gum did not affect AID and standardized ileal digestibility (SID) of CP and AA. Basal EPL was 377 mg\/kg DM intake (DMI) and increasing acacia gum linearly increased (P &amp;lt; 0.05) total tract EPL. Increasing acacia gum linearly decreased (P &amp;lt; 0.05) diet ATTD of P, and STTD of P based on either the calculated EPL or NRC (2012) recommended value (190 mg P\/kg DMI). Increasing acacia gum did not affect AID and ATTD of Ca of diets. In conclusion, feeding increasing dietary fermentable, low-viscous acacia gum decreased diet AID and ATTD of DM and GE, but did not affect AID or SID of CP and AA. Increasing acacia gum decreased ATTD of P, which might have been due to increased specific endogenous losses of P in the total tract of growing pigs.<\/jats:p>","DOI":"10.1093\/jas\/skad204","type":"journal-article","created":{"date-parts":[[2023,6,19]],"date-time":"2023-06-19T19:00:09Z","timestamp":1687201209000},"source":"Crossref","is-referenced-by-count":1,"title":["Effect of increasing dietary fermentable fiber on diet nutrient digestibility and estimation of endogenous phosphorus losses in growing pigs"],"prefix":"10.1093","volume":"101","author":[{"given":"Charlotte M E","family":"Heyer","sequence":"first","affiliation":[{"name":"Department of Agricultural, Food and Nutritional Science, University of Alberta , Edmonton AB T6G 2P5 , Canada"},{"name":"Institute of Animal Science, University of Hohenheim , 70599 Stuttgart , Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li Fang","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Agricultural, Food and Nutritional Science, University of Alberta , Edmonton AB T6G 2P5 , Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3332-2765","authenticated-orcid":false,"given":"Eduardo","family":"Beltranena","sequence":"additional","affiliation":[{"name":"Department of Agricultural, Food and Nutritional Science, University of Alberta , Edmonton AB T6G 2P5 , Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3156-7889","authenticated-orcid":false,"given":"Markus","family":"Rodehutscord","sequence":"additional","affiliation":[{"name":"Institute of Animal Science, University of Hohenheim , 70599 Stuttgart , Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1875-8453","authenticated-orcid":false,"given":"Ruurd T","family":"Zijlstra","sequence":"additional","affiliation":[{"name":"Department of Agricultural, Food and Nutritional Science, University of Alberta , Edmonton AB T6G 2P5 , Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2023,6,19]]},"reference":[{"key":"2023070515135547900_CIT0001","first-page":"903","article-title":"Digestion and balance techniques in pigs.","volume-title":"Swine nutrition","author":"Adeola","year":"2001"},{"key":"2023070515135547900_CIT0002","doi-asserted-by":"crossref","first-page":"2968","DOI":"10.2527\/jas.2009-2285","article-title":"Performance and phosphorus balance of pigs fed diets formulated on the basis of values for standardized total tract digestibility of phosphorus","volume":"88","author":"Almeida","year":"2010","journal-title":"J.
