Rumen Microbiota Predicts Feed Efficiency of Primiparous Nordic Red Dairy Cows

ABSTRACT: Efficient feed utilization in dairy cows is crucial for economic and environmental reasons. The rumen microbiota plays a significant role in feed efficiency, but studies utilizing microbial data to predict host phenotype are limited. In this study, 87 primiparous Nordic Red dairy cows were ranked for feed efficiency during their early lactation based on residual energy intake, and the rumen liquid microbial ecosystem was subsequently evaluated using 16S rRNA amplicon and metagenome sequencing. The study used amplicon data to build an extreme gradient boosting model, demonstrating that taxonomic microbial variation can predict efficiency (rtest = 0.55). Prediction interpreters and microbial network revealed that predictions were based on microbial consortia and the efficient animals had mor
