Social interaction is important in a young foal’s development and the trauma caused by early weaning could offset any benefits of an early weaning program. Deworming helps to ensure health of foals and should begin early in a foal’s life. Many veterinarians suggest starting at 30 days of age and deworming every 30 days until the foals are 1 year old. By four months of age, however, the foal should be eating feed, and is less dependent on its dam for protection and emotional sup-port.
