The average mare has a pregnancy of about 335 days, but normal pregnancies occasionally last over 365 days. The defining aspect of the last part of the equine pregnancy is that the fetus gains size and weight most rapidly during this time, doubling in size and weight during the last 4 to 6 weeks.he mare uses more energy â and requires more nutrition â from the last 6 weeks of pregnancy through the first 6 weeks after foaling than she does at any other time. For a mare that enters the last months of pregnancy in poor condition, it can be very difficult to feed enough to improve her condition.
Since income is generated from selling offspring, yearly foal production is critical to offset maintenance and breeding expenses incurred by the mare owner. With an average gestational length of 333 to 345 days, mares must become pregnant within one month post partum to continue producing foals each year. Mating mares on the first postpartum estrus is one method used to improve the chance of maintaining yearly foal production.
