Emissions were estimated using the IPCC Tier 2 methodology during peak lactation, the full lactation cycle, and the dry period in two commercial groups with distinct productivity. Group A (38\u201340 kg milk\/day) showed higher peak dry matter intake and fiber content than Group B (32\u201335 kg milk\/day), which had greater ether extract (EE) levels. Peak-lactation CH4 emissions were significantly higher in Group A (P\u2009&amp;lt;\u20090.05), while dry-period values did not differ (P\u2009&amp;gt;\u20090.05). Dietary EE was inversely associated with CH4 output, suggesting a potential mitigation pathway. Phase-specific regression models (adjusted R2 = 0.88\u20130.93) confirmed diet composition and physiological stage as major drivers of emissions. Digital twin simulations based on these models offer a non-invasive, reproducible tool for predicting emission scenarios, which is particularly valuable in farms where direct measurements are impractical. These findings highlight the feasibility of integrating diet optimization and predictive modeling into herd management strategies, enabling substantial reductions in CH4 emissions while sustaining milk yield and overall productivity in intensive dairy systems.<\/jats:p>","DOI":"10.1093\/jas\/skaf329","type":"journal-article","created":{"date-parts":[[2025,9,22]],"date-time":"2025-09-22T11:26:53Z","timestamp":1758540413000},"source":"Crossref","is-referenced-by-count":1,"title":["Bridging research and practice using digital twin modeling to mitigate methane emissions across dairy production stages"],"prefix":"10.1093","volume":"103","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2467-6406","authenticated-orcid":false,"given":"Cristina","family":"Castillo","sequence":"first","affiliation":[{"name":"Department of Animal Pathology, IBADER, Faculty of Veterinary Medicine, Campus Terra, University of Santiago de Compostela , Lugo,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9518-808X","authenticated-orcid":false,"given":"Rodrigo","family":"Mui\u00f1o","sequence":"additional","affiliation":[{"name":"Department of Animal Pathology, IBADER, Faculty of Veterinary Medicine, Campus Terra, University of Santiago de Compostela , Lugo,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0862-1672","authenticated-orcid":false,"given":"Jose Luis","family":"Benedito","sequence":"additional","affiliation":[{"name":"Department of Animal Pathology, IBADER, Faculty of Veterinary Medicine, Campus Terra, University of Santiago de Compostela , Lugo,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-6275-7007","authenticated-orcid":false,"given":"Elena Niceas","family":"Martinez","sequence":"additional","affiliation":[{"name":"Department of Animal Pathology, IBADER, Faculty of Veterinary Medicine, Campus Terra, University of Santiago de Compostela , Lugo,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5254-7791","authenticated-orcid":false,"given":"Oscar","family":"Lopez","sequence":"additional","affiliation":[{"name":"Higher Polytechnic Engineering School, University of Santiago de Compostela, Santiago de Compostela , A Coru\u00f1a,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6668-3946","authenticated-orcid":false,"given":"Gregorio","family":"Salcedo","sequence":"additional","affiliation":[{"name":"CIFP La Granja , Heras, Cantabria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2588-0089","authenticated-orcid":false,"given":"Joaquin","family":"Hernandez","sequence":"additional","affiliation":[{"name":"Department of Animal Pathology, IBADER, Faculty of Veterinary Medicine, Campus Terra, University of Santiago de Compostela , Lugo,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2025,10,10]]},"reference":[{"key":"2026010517565222300_skaf329-B2","doi-asserted-by":"publisher","first-page":"54","DOI":"10.3390\/ani6090054","article-title":"Modelling the effect of diet composition on enteric methane emissions across sheep, beef cattle and dairy cows","volume":"6","author":"Bell","year":"2016","journal-title":"Animals"},{"key":"2026010517565222300_skaf329-B3","doi-asserted-by":"publisher","first-page":"9666","DOI":"10.3168\/jds.2021-21650","article-title":"Predicting dry matter intake in mid-lactation Holstein cows using point-in-time data streams available on dairy farms","volume":"105","author":"Brown","year":"2022","journal-title":"J.
