Ruminant livestock are essential for global food production, and understanding sex-specific rumen fermentation microbial differences is key to improving production efficiency meat quality. This study explored variations in backfat thickness, eye muscle area, fermentation, microbiota Qinchuan cattle. The results revealed that heifers exhibited higher butyrate concentrations, acetate/propionate ratio, whereas bulls had larger areas propionate concentrations. Volatile fatty acids (VFAs) transport-related genes (CA4, DRA, NHE1) were more highly expressed bulls. Heifers showed greater diversity with distinct community structures. Bulls a abundance of Prevotella, while butyrate-producing bacteria like Butyrivibrio Pseudobutyrivibrio abundant heifers. Functional predictions enriched glycan biosynthesis amino acid metabolism pathways, enhanced lipid pathways. Correlation analyses thickness was positively correlated acetate but negatively Veillonellaceae_UCG-001. Eye area isobutyrate the Elusimicrobium Anaeroplasma, Lachnospiraceae_NK3A20_group. Redundancy analysis (RDA) identified as drivers differences. Random Forest model predictors including parameters, taxa, metabolic explaining 28% variation. However, not well predicted by current parameters. These findings enhance our profiles, offering potential strategies optimizing management breeding programs.
