Correlations between the Composition of the Bovine Microbiota and Vitamin B₁₂ Abundance.

ABSTRACT: Vitamin B₁₂ is synthesized by prokaryotes in the rumens of dairy cows-and this has implications in human nutrition since humans rely on consumption of dairy products for vitamin B₁₂ acquisition. However, the concentration of vitamin B₁₂ in milk is highly variable, and there is interest in determining what causes vitamin B₁₂ variability. We collected 92 temporally linked rumen, fecal, blood, and milk sample sets from Holstein cows at various stages of lactation fitted with rumen cannula and attempted to define which bacterial genera correlated well with vitamin B₁₂ abundance. The level of vitamin B₁₂ present in each sample was measured, and the bacterial population of each rumen, fecal, and milk sample (n = 263) was an
