Birds were randomly allocated in a completely randomized design by strain into two dietary groups: a control group (corn\u2013soybean meal) and a treatment group in which 7.5% of soybean meal (SBM) was replaced with fermented soybean meal (FSBM). Each group included 175 birds, distributed across seven replicates (pens) with 25 birds per pen. Birds were weighed at the start of the trial and at the end of each rearing phase (starter (1\u201314 days of age), and grower phases (15\u201335 days of age)). Mortality was monitored daily throughout the experiment. Weekly feed intake was recorded for each pen. On day 35, 14 birds were randomly selected from each treatment\u2013strain combination for carcass and meat quality evaluation. Data were analyzed with linear models; strain, diet, and their interaction were the investigated effects. No strain\u2013diet interaction was detected for growth performance, carcass and meat quality, and intestinal morphology traits (p &gt; 0.05). Significant interaction effect on crude protein digestibility is found (p &lt; 0.001). The FSBM improved crude protein digestibility for the Indian River broiler strain, while the opposite occurred in the Ross 308 strain. Fermented soybean meal supplementation did not significantly affect body weight gain, feed conversion ratio (FCR), or feed intake during the study period (p &gt; 0.05). The Ross strain exhibited a higher dressing percentage (p = 0.04) and greater cooking loss (p = 0.01), whereas the Indian River strain showed higher abdominal fat percentage (p = 0.04) and shear force (p = 0.003). The dressing percentage, pH, color parameters, cooking loss, water-holding capacity, and breast fillet yield for FSBM and control groups did not differ (p &gt; 0.05). Ileum villus length and width were significantly higher (p &lt; 0.05) in the FSBM group compared to the control group. In conclusion, Fermented soybean meal can enhance intestinal morphology and crude protein digestibility in a strain-specific manner; however, its impact on growth and carcass attributes is limited at this inclusion level.<\/jats:p>","DOI":"10.3390\/ani15182659","type":"journal-article","created":{"date-parts":[[2025,9,11]],"date-time":"2025-09-11T08:55:02Z","timestamp":1757580902000},"page":"2659","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Effects of Fermented Soybean Meal Supplementation on Growth, Carcass Quality, and Intestinal Morphology in Ross 308 and Indian River Broilers"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8508-755X","authenticated-orcid":false,"given":"Mohammad D.","family":"Obeidat","sequence":"first","affiliation":[{"name":"Department of Animal Production, Faculty of Agriculture, Jordan University of Science and Technology (JUST), Irbid 22110, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sadeh Q.","family":"Alzoubi","sequence":"additional","affiliation":[{"name":"Department of Animal Production, Faculty of Agriculture, Jordan University of Science and Technology (JUST), Irbid 22110, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3195-2488","authenticated-orcid":false,"given":"Basheer M.","family":"Nusairat","sequence":"additional","affiliation":[{"name":"Department of Animal Production, Faculty of Agriculture, Jordan University of Science and Technology (JUST), Irbid 22110, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0315-4032","authenticated-orcid":false,"given":"Belal S.","family":"Obeidat","sequence":"additional","affiliation":[{"name":"Department of Animal Production, Faculty of Agriculture, Jordan University of Science and Technology (JUST), Irbid 22110, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2353-7823","authenticated-orcid":false,"given":"David G.","family":"Riley","sequence":"additional","affiliation":[{"name":"Department of Animal Science, College of Agriculture and life Sciences, Texas A&M University, College Station, TX 77843, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"102133","DOI":"10.1016\/j.psj.2022.102133","article-title":"Effects of Early Post-Hatch Feeding on the Growth Performance, Hormone Secretion, Intestinal Morphology, and Intestinal Microbiota Structure in Broilers","volume":"101","author":"Li","year":"2022","journal-title":"Poult.
