How long does the mother horses suckle the baby or babies?

Mother horses, or mares, typically allow their foals to suckle for about 4 to 6 months. During this time, the foals receive essential nutrients and antibodies from the mare's milk. After this period, foals gradually start to eat solid food and wean off the milk, though they may continue to nurse occasionally for a few more months. Full weaning usually occurs by 6 to 7 months of age.
