This long-term study investigated the ruminal and duodenal microbiome and metabolites during calving as an individual challenge and a lipopolysaccharide-induced systemic inflammation as a standardized challenge. Strong inter- and intra-individual microbiome changes were noted during the entire trial period of 168\u2006days and between the 12 sampling time points.<jats:italic>Bifidobacterium<\/jats:italic>increased significantly at 3 days after calving. Both challenges increased the intestinal abundance of fiber-associated taxa, e.g.,<jats:italic>Butyrivibrio<\/jats:italic>and unclassified<jats:italic>Ruminococcaceae<\/jats:italic>. NMR analyses of rumen and duodenum samples identified up to 60 metabolites out of which fatty and amino acids, amines, and urea varied in concentrations triggered by the two challenges. Correlation analyses between these parameters indicated a close connection and dependency of the microbiome with its host. It turns out that the combination of phylogenetic with metabolite information supports the understanding of the true scenario in the forestomach system. The individual stages of the production cycle in dairy cows reveal specific criteria for the interaction pattern between microbial functions and host responses.<\/jats:p>","DOI":"10.3389\/fmicb.2022.1000750","type":"journal-article","created":{"date-parts":[[2022,11,16]],"date-time":"2022-11-16T05:25:02Z","timestamp":1668576302000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":10,"title":["Cow\u2019s microbiome from antepartum to postpartum: A long-term study covering two physiological challenges"],"prefix":"10.3389","volume":"13","author":[{"given":"Johanna","family":"Tr\u00f6scher-Mu\u00dfotter","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simon","family":"Deusch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Borda-Molina","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jana","family":"Frahm","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sven","family":"D\u00e4nicke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Am\u00e9lia","family":"Camarinha-Silva","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Korinna","family":"Huber","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jana","family":"Seifert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,11,16]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"2359","DOI":"10.1039\/C6MB00217J","article-title":"The bovine milk microbiota: insights and perspectives from-omics studies","volume":"12","author":"Addis","year":"2016","journal-title":"Mol.
