Maternal nutrition during gestation profoundly influences fetal growth, organogenesis, and long-term offspring performance through developmental programming. Among the molecular mechanisms responsive to maternal nutrient availability, one-carbon metabolism plays a central role by integrating folate, methionine, choline, and vitamin B12 pathways that regulate methylation, nucleotide synthesis, and antioxidant defense. These processes link maternal nutritional status to epigenetic remodeling, cellular proliferation, and redox balance during fetal development. Mitochondria act as nutrient sensors that translate maternal metabolic cues into bioenergetic and oxidative signals, shaping tissue differentiation and metabolic flexibility. Variations in maternal diet have been associated with shifts in fetal amino acid, lipid, and energy metabolism, suggesting adaptive responses to constrained intrauterine environments. This review focuses on the molecular interplay between one-carbon metabolism, mitochondrial function, and metabolomic adaptation in developmental programming of ruminant livestock. Understanding these mechanisms offers opportunities to design precision nutritional strategies that enhance fetal growth, offspring productivity, and long-term resilience in livestock production systems.
