Many broodmares are currently in the latter half of gestation, a crucial period for foal development in the mare’s uterus, as recognized by the Nutrient Requirements of Horses, Sixth Edition. Starting from the 6th month of gestation, the mare’s nutrient requirements begin to increase, earlier than previously understood.
During the final three months of gestation, foals may gain an average of one pound per day. Managing pregnant mares involves maintaining an appropriate body condition score, ensuring adequate protein and amino acid intake for placental and fetal development, and providing sufficient minerals and trace minerals for both foal development and immune support. Vaccination and deworming programs should be implemented in collaboration with a veterinarian to protect both mare and foal.
While good quality pasture or forage may suffice for energy needs late in gestation, it may lack essential amino acids and minerals. Therefore, introducing a well-designed ration balancer product from the 5th to 10th or 11th month of gestation can bridge nutritional gaps. Transitioning to a broodmare and foal feed prior to foaling ensures a smooth dietary transition and provides necessary nutrients for lactation and foal growth. Access to fresh water and salt should be available at all times.
Properly feeding the broodmare reduces the risk of developmental issues in the foal and facilitates timely rebreeding for future foals if desired.
