What Lactation period of a horse?

The lactation period of a horse typically lasts about 4 to 6 months. During this time, the mare produces milk to nourish her foal, which gradually begins to eat solid food around 2 to 3 months of age. As the foal matures, the mare's milk production decreases, and the foal becomes more independent. After weaning, which usually occurs between 4 to 6 months, the foal is fully transitioned to a diet of forage and grain.
