Topic:Gestation

Gestation in horses refers to the period during which a mare carries a developing fetus, typically lasting around 11 months, or approximately 340 days. This process involves a series of physiological and hormonal changes that support fetal development and prepare the mare for parturition. Key stages of equine gestation include fertilization, embryonic development, and fetal growth, each characterized by specific developmental milestones. Monitoring the health and progress of gestation is essential for ensuring the well-being of both the mare and the foal. This page compiles peer-reviewed research studies and scholarly articles that explore the various aspects of equine gestation, including hormonal regulation, fetal development, and factors influencing gestational length and outcomes.

DARLINGTON RW, RANDALL CC.Equine abortion virus was purified from the plasma of infected golden Syrian hamsters by differential centrifugation and nuclease treatment. The preparations were essentially free of nonviral elements on electron microscopic examination, and sedimentation in sucrose and potassium tartrate density gradients resulted in a single visible band. Electron microscopy of this band showed it to be composed of viral particles, and injection into hamsters resulted in infection and death of the animals. The viral particles had a sedimentation coefficient of approximately 2200 S and a hydrated density of 1...

The estrogens of the pregnant mare.

Endocrinology March 1, 1961 Volume 68 411-416 doi: 10.1210/endo-68-3-411

SAVARD K.The urinary ketonic estrogens were studied at monthly intervals in five pregnant mares. Estrone and equilin appear to be the principal components and equilenin a minor constituent of the mares’ estrogens. The levels of equilin rise from the 4–5th months to equal and in some instances exceed those of estrone in the late months of pregnancy. A partition chromatographic method for the separation of the ketonic phenolic steroids of pregnant mares’ urine is described.

SAVARD K, THOMPSON HG, GUT M, DORFMAN RI.The biosynthetic origins of the ring-B unsaturated estrogens, equilin and cquilcnin have been the subject of considerable speculation. Girard and associates (1,2) first iso- lated these compounds, in addition to estrone, from the urine of pregnant marcs, and observed that their proportions increased during the latter months of pregnancy, at a time when the total estrogen (estrone) content of the urine diminished (2,3). Heard and associates (4) reported that estrone-C14 administered to a pregnant marc was not trans- formed to equilin nor equilenin (5). We have explored in the mare the pos...
