Topic:Fetal Development

Fetal development in horses refers to the progression of growth and differentiation that occurs from conception until birth. This process involves a series of complex stages, beginning with fertilization and continuing through embryonic and fetal stages. Key developmental milestones include organogenesis, skeletal formation, and maturation of physiological systems. The equine gestation period averages around 340 days, during which the fetus undergoes significant anatomical and functional changes. Understanding fetal development in horses is essential for optimizing breeding practices and ensuring the health of both mare and foal. This page compiles peer-reviewed research studies and scholarly articles that explore the stages, mechanisms, and factors influencing fetal development in equines.

Bhavnani BR, Short RV, Solomon S.A mixture of 14C-sodium acetate and 3H-cholesterol was injected into the umbilical circulation of a pregnant mare in the 3OOth day of gestation. The abdomen was closed and urine was collected for 3.5 days. The mare delivered a normal live foal 23 days later. Steroid conjugates present in the maternal urine were hydrolyzed and separated into neutral and phenolic fractions. From the phenolic “sulfate” fraction estrone, 17α-estradiol, equilin, equilenin, and 17α-dihydroequilenin were isolated. Only estrone and 17α-estradiol contained both 3H and 14C, while the ring-B unsaturated estrogens ...
