Five experimental diets were obtained by supplementing a basal diet with 6% of P (P6), 6% of SA (SA6), 4% of P + 2% SA (P4-SA2), 2% of P + 4% of SA (P2-SA4) and 6% of S (S6). A total of 480 one-d-old female broiler chickens (Ross 308) were housed in metabolic cages (6 cages\/treatment, with 16 birds\/cage). Replacing P with SA improved fat absorption at 11 and 35 d (p &lt; 0.05), but not feed AME values and saturated FA (SFA) digestibility at 11 d. As age increased, the absorption of SFA and free fatty acids (FFA) improved, and the contribution of the upper ileum to FA absorption increased (p &lt; 0.05). At 35 d, SA6 (56% FFA) and P2-SA4 (40% FFA, 2.6 unsaturated-to-saturated FA ratio) could replace S6 without impairing fat utilization. The replacement of P with SA represents a suitable strategy to use this by-product.<\/jats:p>","DOI":"10.3390\/ani11092586","type":"journal-article","created":{"date-parts":[[2021,9,6]],"date-time":"2021-09-06T10:59:12Z","timestamp":1630925952000},"page":"2586","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Replacement of Palm Oil with Soybean Acid Oil in Broiler Chicken Diet: Fat Digestibility and Lipid Class Content along the Intestinal Tract"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6613-3370","authenticated-orcid":false,"given":"Beatriz","family":"Jimenez-Moya","sequence":"first","affiliation":[{"name":"Animal Nutrition and Welfare Service (SNiBA), Animal and Food Science Department, Faculty of Veterinary, Universitat Aut\u00f2noma de Barcelona, Edifici V, Travessera dels Turons, 08193 Bellaterra, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana C.","family":"Barroeta","sequence":"additional","affiliation":[{"name":"Animal Nutrition and Welfare Service (SNiBA), Animal and Food Science Department, Faculty of Veterinary, Universitat Aut\u00f2noma de Barcelona, Edifici V, Travessera dels Turons, 08193 Bellaterra, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8624-8749","authenticated-orcid":false,"given":"Francesc","family":"Guardiola","sequence":"additional","affiliation":[{"name":"Libifood Research Group, Departament de Nutrici\u00f3, Ci\u00e8ncies de l\u2019Alimentaci\u00f3 i Gastronomia, INSA-UB, XIA, Campus de l\u2019Alimentaci\u00f3 Torribera, Facultat de Farm\u00e0cia i Ci\u00e8ncies de l\u2019Alimentaci\u00f3, Universitat de Barcelona, Av Prat de la Riba, 171, 08921 Santa Coloma de Gramenet, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3840-197X","authenticated-orcid":false,"given":"Mar\u00eda Dolores","family":"Soler","sequence":"additional","affiliation":[{"name":"AviFeed Science, Department of Animal Production and Health Public Veterinary Health and Food Science and Technology, Facultad de Veterinaria, Universidad Cardenal Herrera-CEU, CEU Universities, Calle Tirant lo Blanch 7, 46115 Alfara del Patriarca, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raquel","family":"Rodriguez-Sanchez","sequence":"additional","affiliation":[{"name":"AgResearch Ltd., Ruakura Research Centre, 10 Bisley Road, Private Bag 3123, Hamilton 3214, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0797-5025","authenticated-orcid":false,"given":"Roser","family":"Sala","sequence":"additional","affiliation":[{"name":"Animal Nutrition and Welfare Service (SNiBA), Animal and Food Science Department, Faculty of Veterinary, Universitat Aut\u00f2noma de Barcelona, Edifici V, Travessera dels Turons, 08193 Bellaterra, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,3]]},"reference":[{"key":"ref_1","unstructured":"(2021, March 23).
