The Claim

Enrichment of the rumen microbial taxa Succiniclasticum, Lactobacillus, Prevotellaceae NK3B31_group, and Muribaculaceae_unclassified during nighttime is associated with higher milk fat levels in dairy cows, suggesting a potential role of these microbes in circadian-regulated milk synthesis.

In plain English

When certain gut bacteria in cows are more active at night, it might help them make milk with more fat — kind of like how our body uses food differently depending on the time of day.

See the scientific wording

The rumen microbial taxa Succiniclasticum, Lactobacillus, Prevotellaceae NK3B31_group, and Muribaculaceae_unclassified are associated with higher milk fat levels in dairy cows when enriched during nighttime, indicating a potential microbial contribution to circadian-regulated milk synthesis.

What the research says

1 study
  1. Study: Circadian Rhythm Enhances mTORC1/AMPK Pathway-Mediated Milk Fat Synthesis in Dairy Cows via the Microbial Metabolite Acetic Acid.

    The study found that certain gut microbes in cows are more active at night and help produce more milk fat by releasing a substance that gets into the bloodstream and boosts fat-making in the udder.
