Multi-omics analysis reveals Oscillibacter valericigenes gavage increases fetal and placental weights and is associated with altered estrogen-related metabolism and valerate production in mice.
BACKGROUND Our prior work associated Oscillibacter valericigenes and valerate-related features with offspring birth weight in Landrace × Yorkshire sows, but functional evidence was limited. OBJECTIVES To test whether O. valericigenes or valerate increases late-gestation fetal weight and characterize maternal metaboli...
