dc.descriptionABSTRACT. Diet influences ruminal methane emissions by modulating the compositionand activity of the rumen microbiome. However, how diet shapes the functional capacityof the rumen microbiome in Nelore cattle (Bos indicus), a key tropical beef breed, remainsunclear. This study used metatranscriptomics to investigate how dietary supplementation with agro-industrial by-products affects the active rumen microbiome and itsassociation with residual methane emissions. Rumen samples from 50 Nelore cattle fedeither a conventional or by-product-based diet revealed that the active microbiome wasdominated by bacteria (88.4% ± 3.16%) and archaea (11.6% ± 3.16%), with no significanttaxonomic differences between diets. Despite this, functional profiling identified genesfrom 193 pathways and 3,512 gene families, with distinct metabolic signatures betweendiets. Specifically, six pathways and 87 gene families were unique to the conventionaldiet, while seven pathways and 210 gene families were unique to the by-product diet.The associations between gene families enriched under each diet with residual methaneemission revealed that the expression of two gene families exhibited negative correlations, while five were positively correlated with methane emission under conventionaldiet. In the by-product diet, we identified five gene families positively associated withmethane emissions and 14 negatively associated. These results demonstrate that dietalters rumen microbial functions with methane mitigation potential, without affectingtaxonomic composition.
