Wondering if your mare is ever going to foal? Horses have one of the broader normal ranges for a full term pregnancy. The normal range can be anywhere from 330 days post ovulation to 360 with 340 days being the average. Foals typically need to be born after 320 days of gestation to be viable. Some foals can even go over 400 days in gestation with a viable fetus. If you are concerned about your mare's pregnancy, we always recommend scheduling an appointment with your reproductive veterinarian to make sure all is well with your foal.
