Two thousand steers [50% beef, 25% Holstein, 25% Jersey genetics; initial shrunk body weight (SBW)\u2005=\u2005288.2\u2005\u00b1\u20058.0 kg] were blocked by arrival date and randomly assigned to receive 1 of 2 treatments: 1) SCFP supplied in the starter diet at 12\u00a0g per steer daily and then 9\u00a0g per steer daily in the finishing diet (NS; NaturSafe\u2122, Diamond V, Cedar Rapids, IA) or 2) DFM fed at 50\u00a0mg per steer daily throughout the feeding period (BD; Bovamine Defend, Chr. Hansen, Milwaukee, WI). Pen served as the experimental unit (200 steers\/pen), with 5 pens per treatment. Data were analyzed as a randomized complete block design in R 4.2.2. with the main effect of treatment and random effect of block included in the model. Results were reported on a deads-in basis unless otherwise stated. Cattle were fed for a total of 275\u2005\u00b1\u20056.2 d. Initial and final SBW did not differ (P\u2005\u2265\u20050.84) by treatment. Initial treatment pulls were observed more frequently for NS compared to BD cattle (29.43% vs. 21.67%; P\u2005&amp;lt;\u20050.01). However, NS cattle had a lesser rate of repulls as a proportion of initial pulls (10.08% vs. 16.61%; P\u2005=\u20050.03). Fewer (P\u2005&amp;lt;\u20050.01) bullers were reported amongst NS cattle. Cattle supplemented with NS had a lower case fatality rate (6.08% vs. 11.96%; P\u2005&amp;lt;\u20050.01) and tended to have a lower total mortality rate (1.60% vs. 2.70%; P\u2005=\u20050.09) than BD. With deads included, average daily gain (ADG) tended (P\u2005=\u20050.06) to be greater for NS cattle. Dry matter intake did not differ (P\u2005=\u20050.99) by treatment; however, NS cattle had a numeric advantage in feed efficiency (G:F) nearing a tendency (0.132 vs. 0.130; P\u2005=\u20050.11). On a deads-out basis, ADG and G:F were similar (P\u2005\u2265\u20050.85). Dressing percentage tended (P\u2005\u2264\u20050.10) to be greater for NS carcasses. Cattle fed BD had a greater (P\u2005=\u20050.03) proportion of USDA Prime carcasses. While treatment had no impact on liver abscess severity or total abscess occurrence, NS cattle tended to have less A- abscesses (1.72% vs. 3.87%; P\u2005=\u20050.10). In this large-pen comparison, SCFP supplementation improved feedlot cattle health and positively influenced performance compared to a DFM.<\/jats:p>","DOI":"10.1093\/tas\/txaf098","type":"journal-article","created":{"date-parts":[[2025,7,24]],"date-time":"2025-07-24T06:04:03Z","timestamp":1753337043000},"source":"Crossref","is-referenced-by-count":1,"title":["Effects of feeding a <i>Saccharomyces cerevisiae<\/i> fermentation product compared to a direct-fed microbial in finishing diets of beef \u00d7 dairy crossbred steers fed in the Pacific Northwest"],"prefix":"10.1093","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-0906-5367","authenticated-orcid":false,"given":"Sydney M","family":"Bowman-Schnug","sequence":"first","affiliation":[{"name":"Department of Animal and Food Sciences, Texas Tech University , Lubbock, TX 79409 ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bradley J","family":"Johnson","sequence":"additional","affiliation":[{"name":"Department of Animal and Food Sciences, Texas Tech University , Lubbock, TX 79409 ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"O Abe","family":"Turgeon","sequence":"additional","affiliation":[{"name":"Turgeon Consulting Service, LLC , Amarillo, TX 79118 ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joaquin","family":"Figueroa","sequence":"additional","affiliation":[{"name":"Beef Northwest Research , Pendleton, OR 97801 ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Craig R","family":"Belknap","sequence":"additional","affiliation":[{"name":"Diamond V , Cedar Rapids, IA 52404 ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zebadiah T L","family":"Gray","sequence":"additional","affiliation":[{"name":"Diamond V , Cedar Rapids, IA 52404 ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas S","family":"Edrington","sequence":"additional","affiliation":[{"name":"Diamond V , Cedar Rapids, IA 52404 ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2025,7,22]]},"reference":[{"key":"2025080105570406400_CIT0001","first-page":"31","article-title":"Non-genetic factors that affect quality grade of fed cattle","author":"Anderson","year":"2007"},{"key":"2025080105570406400_CIT0002","doi-asserted-by":"publisher","first-page":"1","DOI":"10.18637\/jss.v067.i01","article-title":"Fitting linear mixed-effects models using lme4","volume":"67","author":"Bates","year":"2015","journal-title":"J.
