Two important components of livestock rations in the United States are co-products from grain processing: soybean meal (SBM) from soybean crushing, and distillers grains and solubles (DGS) from corn ethanol production. In response to interest in low-carbon beef production, this study estimates the likely carbon intensity (CI) scores of these two co-product feeds, using two life-cycle emissions packages available for use by producers and others. For feedstuffs produced in the Northern Plains we find expected CI estimates of 0.196\u20130.385\u2009kg CO\u2082e kg\u22121 of dry matter for DGS and 0.330\u20130.456\u2009kg CO\u2082e kg\u22121 of dry matter for SBM. The analysis reveals that expected co-product CIs for a given product and model vary by 15%\u201319% across subregions in which the crop was grown, and that CI of co-products from irrigated crops in this region are about 10% lower than those from non-irrigated crops. These results suggest that beef producers may find opportunities to reduce their product CI by choosing among available supplies of distillers grains and soybean meal.<\/jats:p>","DOI":"10.1093\/tas\/txag137","type":"journal-article","created":{"date-parts":[[2026,9,17]],"date-time":"2026-09-17T19:32:14Z","timestamp":1789673534000},"source":"Crossref","is-referenced-by-count":0,"title":["The carbon intensity (CI) of co-products fed to beef cattle in the Northern Plains"],"prefix":"10.1093","volume":"10","author":[{"given":"Felipe","family":"Almeida","sequence":"first","affiliation":[{"name":"Department of Agricultural Economics, University of Nebraska , Lincoln, NE 68583,","place":["United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9739-8753","authenticated-orcid":false,"given":"Richard K","family":"Perrin","sequence":"additional","affiliation":[{"name":"Department of Agricultural Economics, University of Nebraska , Lincoln, NE 68583,","place":["United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lilyan E","family":"Fulginiti","sequence":"additional","affiliation":[{"name":"Department of Agricultural Economics, University of Nebraska , Lincoln, NE 68583,","place":["United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elliott","family":"Dennis","sequence":"additional","affiliation":[{"name":"Department of Agricultural Economics, University of Nebraska , Lincoln, NE 68583,","place":["United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,9,18]]},"reference":[{"key":"2026092923065359100_txag137-B1","doi-asserted-by":"publisher","first-page":"520","DOI":"10.1007\/s11367-012-0386-y","article-title":"Regional carbon footprint analysis of dairy feeds for milk production in the USA","volume":"17","author":"Adom","year":"2012","journal-title":"Int.
