Comparative analysis of ruminal and fecal microbiomes in Holstein, Jersey, and Jeju Black cattle using multiple taxonomic classifiers.

ABSTRACT: The gastrointestinal microbiome is pivotal to nutrient utilization and productivity in dairy cattle. This study compared the ruminal and fecal microbiomes of Holstein, Jersey, and Jeju Black cattle using 16S rRNA gene sequencing and three taxonomic classification databases to identify microbial differences across breeds. A total of 25 samples were analysed to evaluate microbial composition, diversity, functional phenotypes, and interactions. Jeju Black cattle exhibited significantly higher ruminal diversity (p < 0.001), whereas Holstein and Jersey cows had more diverse fecal microbiomes. Prevotella, Ruminococcus and Succinivibrio dominated the rumen of commercial breeds, while Methanobrevibacter and Desulfovibrio were enriched in Jeju Black cattle.
