In Experiment 1, 139 steers (440.4 \u00b1 31.0 kg) were randomly assigned to one of 16 pens with pen randomly assigned to one of two treatments: 1) Control (CON, bunks managed to be devoid of feed prior to feeding), or 2) Over-fed (OVF, bunks managed to have minimum of 2.54 cm of feed remaining each morning) during adaptation. Following adaptation all steers in Experiment 1 were transitioned to CON bunks and followed to finishing. In Experiment 2, 126 steers (445.4 \u00b1 40.63 kg) were randomly assigned to one of 16 pens. Treatments in Experiment 2 were arranged in a 2 \u00d7 2 factorial and include the two bunk management strategies utilized in Experiment 1 (OVF or CON) and either 25% MDGS or 50% MDGS (DM basis). Ruminal H2S was measured via rumenocentesis during dietary adaptation. There were no differences (P \u2265 0.13) observed in either experiment for growth performance due to bunk management. In Experiment 1, OVF steers had greater (P = 0.001) DMI during adaptation; however, overall DMI was not different (P = 0.14) between treatments. In Experiment 2, DMI (d 0 to 104) tended to decrease (P = 0.09) with greater MDGS inclusion. Hot carcass weight, ribeye area, marbling score, and quality grade were not affected (P \u2265 0.48) by either bunk management or MDGS inclusion. In Experiment 2, back fat (1.30 vs. 1.17 \u00b1 0.042 cm) and yield grade (3.2 vs. 3.0 \u00b1 0.11) were greater (P = 0.03) for CON steers compared with OVF but were not affected (P = 0.59) by MDGS inclusion. In Experiment 1, H2S tended (P = 0.07) to be greater in steers on OVF compared with CON. In Experiment 2, bunk management strategy did not impact (P = 0.82) H2S concentrations. There was a MDGS inclusion \u00d7 day interaction for H2S with steers fed 50% MDGS having greater (P &amp;lt; 0.01) H2S concentrations compared with steers fed 25% MDGS on d 28 and 35. Bunk management strategy during adaptation did not impact growth performance but did reduce intake in Experiment 1. Yield grade decreased when OVF bunk management was applied throughout Experiment 2. Response of H2S concentrations in the rumen were variable and likely influenced by inconsistencies in bunk management and resulting DMI during the early portions of the feedlot study.<\/jats:p>","DOI":"10.1093\/tas\/txab194","type":"journal-article","created":{"date-parts":[[2021,10,6]],"date-time":"2021-10-06T12:05:56Z","timestamp":1633521956000},"source":"Crossref","is-referenced-by-count":0,"title":["Impacts of bunk management on steer performance and ruminal hydrogen sulfide concentrations in steers fed modified distillers grains with solubles"],"prefix":"10.1093","volume":"5","author":[{"given":"Bryan W","family":"Neville","sequence":"first","affiliation":[{"name":"Carrington Research Extension Center, North Dakota State University, Carrington, ND 58421, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leslie A","family":"Lekatz","sequence":"additional","affiliation":[{"name":"Department of Agriculture and Natural Resources, University of Minnesota Crookston, Crookston, MN 56716, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rebecca L","family":"Moore","sequence":"additional","affiliation":[{"name":"Carrington Research Extension Center, North Dakota State University, Carrington, ND 58421, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wayde J","family":"Pickinpaugh","sequence":"additional","affiliation":[{"name":"Carrington Research Extension Center, North Dakota State University, Carrington, ND 58421, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cierrah J","family":"Kassetas","sequence":"additional","affiliation":[{"name":"Department of Animal Sciences, North Dakota State University, Fargo, ND 58102, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2021,10,6]]},"reference":[{"key":"2021103114473077600_CIT0001","volume-title":"Official methods of analysis","author":"AOAC","year":"2010","edition":"18"},{"key":"2021103114473077600_CIT0002","doi-asserted-by":"crossref","first-page":"3763","DOI":"10.2527\/jas.2013-7242","article-title":"High-sulfur in beef cattle diets: a review","volume":"92","author":"Drewnoski","year":"2014","journal-title":"J.
