How long is a horse pregnant? The period of gestation is the time starting when a baby is conceived in the womb until it is born. A horses' gestation period is roughly 11 months (or 340 days).

Main article: Horse reproduction. A mare may be 4 to 10 days in heat and about 14 days in diestrus. Thus a cycle may be short, e.g., 3 weeks. Horses mate in spring and summer, autumn is a transition time, and anestrus rules the winter. A feature of the fertility cycle of horses and other large herd animals is that it is usually affected by the seasons.
