This intricate consortium of bacteria, archaea, protozoa, and fungi plays a central role in the degradation and fermentation of fibrous plant material, ultimately converting it into absorbable nutrients and energy for the host. Beyond its fundamental role in nutrient metabolism, the rumen microbiota exerts profound effects on animal health, immunity, productivity, and environmental sustainability. Understanding its structure and function is therefore critical not only for improving livestock production but also for advancing sustainable agricultural systems in the face of global challenges such as climate change and food security...2025http://zaguan.unizar.es/record/16839710.3389/fmicb.2025.1720795http://zaguan.unizar.es/record/168397oai:zaguan.unizar.es:168397info:eu-repo/grantAgreement/ES/AEI/CNS2024-154467info:eu-repo/grantAgreement/ES/AEI/PID2021-127949OB-I00info:eu-repo/grantAgreement/ES/AEI/MICNN/PID2021-123206OB-I00info:eu-repo/grantAgreement/ES/MICINN/RYC2019-027764-I/AEI/10.13039/501100011033Frontiers in Microbiology 16 (2025), 1720795 [3 pp.]byhttps://creativecommons.org/licenses/by/4.0/deed.esinfo:eu-repo/semantics/openAccess
