Steers were allocated to 1 of 32 pens [n\u2005=\u2005200\/pen] within 16 total blocks, and assigned to 1 of 2 dietary treatments; no probiotic (CON) or 2 g*steer-1*d-1 of Lactobacillus acidophilus, Enterococcus faecium, Pediococcus pentosaceus, Lactobacillus brevis and Lactobacillus plantarum providing a total of 1 billion CFU (10-G). At harvest, subiliac lymph nodes were randomly obtained from 40 animals from each pen for blocks 1 through 10. Data were analyzed as a randomized complete block design, and pen served as the experimental unit. No differences (P\u2005\u2265\u20050.26) were observed between treatments for DMI, final BW, average daily gain, or feed efficiency. When evaluating carcass characteristics, there were no differences (P\u2005\u2265\u20050.15) for hot carcass weight or liver abscess prevalence. However, dressed carcass yield differed (P\u2005=\u20050.02) between treatments (CON\u2005=\u200564.74%, 10-G\u2005=\u200564.52%). No differences (P\u2005\u2265\u20050.12) were observed for marbling score, longissimus muscle area, 12th rib s.c. fat depth, or USDA quality grade outcomes. Lower frequency (P\u2005&amp;lt;\u20050.01; CON\u2005=\u200536.95%, 10-G\u2005=\u200523.60%) of Salmonella positive subiliac lymph nodes was observed for cattle supplemented dietary 10-G, whereas concentration of Salmonella quantifiable samples did not differ (P\u2005=\u20050.23) between treatments (CON\u2005=\u20050.84 Log10CFU\/g, 10-G\u2005=\u20050.63 Log10CFU\/g). In conclusion, the supplementation of 10-G direct fed microbial did not influence live or carcass performance within this trial; however, prevalence of Salmonella positive subiliac lymph nodes was reduced.<\/jats:p>","DOI":"10.1093\/tas\/txaf050","type":"journal-article","created":{"date-parts":[[2025,4,14]],"date-time":"2025-04-14T05:30:01Z","timestamp":1744608601000},"source":"Crossref","is-referenced-by-count":2,"title":["Effects of feeding 10-G direct-fed microbial on feedlot performance, carcass characteristics, and prevalence of <i>Salmonella<\/i> in subiliac lymph nodes of feedlot steers"],"prefix":"10.1093","volume":"9","author":[{"given":"Aubrey C","family":"Thompson","sequence":"first","affiliation":[{"name":"Beef Carcass Research Center, Department of Agricultural Sciences, West Texas A&M University , Canyon, TX 79016 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tony C","family":"Bryant","sequence":"additional","affiliation":[{"name":"Five Rivers Cattle Feeding , Johnstown, CO 80534 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jenny S","family":"Jennings","sequence":"additional","affiliation":[{"name":"Five Rivers Cattle Feeding , Johnstown, CO 80534 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kevin","family":"Martens","sequence":"additional","affiliation":[{"name":"Life Products Inc , Norfolk, NE 68701 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Loni W","family":"Lucherk","sequence":"additional","affiliation":[{"name":"Beef Carcass Research Center, Department of Agricultural Sciences, West Texas A&M University , Canyon, TX 79016 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Travis C","family":"Tennant","sequence":"additional","affiliation":[{"name":"Beef Carcass Research Center, Department of Agricultural Sciences, West Texas A&M University , Canyon, TX 79016 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7088-5455","authenticated-orcid":false,"given":"Ty E","family":"Lawrence","sequence":"additional","affiliation":[{"name":"Beef Carcass Research Center, Department of Agricultural Sciences, West Texas A&M University , Canyon, TX 79016 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2025,4,14]]},"reference":[{"key":"2025073108114773300_CIT0001","doi-asserted-by":"publisher","first-page":"1752","DOI":"10.4315\/0362-028x-71.9.1752","article-title":"Source tracking of Escherichia coli O157:H7 and Salmonella contmaination in the lairage environment at commercial U.S. beef processing plants and identification of an effective intervention","volume":"71","author":"Arthur","year":"2008","journal-title":"J.
