I just saw this video on YouTube that really surprised me. There was an orphaned foal whose mom sadly died at birth. The foal was introduced to another mare—who wasn’t pregnant and hadn’t foaled in a long time—and amazingly, the mare not only accepted the foal but also started producing milk for her!
I had no idea this was even possible. Apparently, mares can sometimes start lactating without being pregnant, even if they’re virgins or it’s been years since their last foal, as long as they bond with and accept the orphan. The suckling stimulates milk production, and combined with the mare’s maternal instincts, she can actually feed the foal.
From what I learned, it seems that if an orphaned foal is introduced carefully and the mare bonds with it, the mare can eventually lactate even without being pregnant. The presence of the foal and the stimulation from suckling can trigger milk production, sometimes even in virgin mares or mares who haven’t foaled for years.
I thought this was incredible — I didn’t realize horses had this kind of flexibility.
