Abstract

This article focuses on the effects of dietary restriction and one-carbon metabolite (OCM) supplementation on the maternal gut and vaginal microbiota in beef heifers during early gestation. In a controlled study with 32 beef heifers, dietary restriction significantly altered the ruminal and vaginal microbial community structures, increasing microbial richness and shifting the abundance of specific bacterial phyla and genera by day 63 of gestation. In contrast, OCM supplementation, which included ruminal-protected methionine, choline, folate, and vitamin B12, had minimal impact on the composition and diversity of these microbial communities. These findings highlight that maternal nutrient intake during early pregnancy influences the maternal microbiome, with potential implications for maternal and fetal health.
