Multi-omics reveals that the rumen microbiome and its metabolome together with the host metabolome contribute to individualized dairy cow performance

Short summary

High milk protein yield in dairy cows is linked to specific rumen microbes like Prevotella, which enhance branched-chain amino acid production and reduce methane. Host metabolism also plays a significant role, with rumen microbial composition and metabolites accounting for over 69% of performance variation.
