Spring has sprung, which means foaling season is in full swing! Here is some great information about mare wax and foaling from our friends at Idaho Equine Hospital:
"🐴 Mares Wax: A Key Sign Foaling is Near
If you’re monitoring a pregnant mare, one of the most talked-about signs of impending foaling is “waxing.” But what does it actually mean?
Mares wax when small, bead-like droplets of colostrum (first milk) appear on the ends of the teats. This happens as the udder fills and the body prepares for birth.
✨What to know:
- Waxing usually occurs 12–48 hours before foaling, though timing can vary.
- Not all mares will wax—so don’t rely on this sign alone.
- The presence of wax indicates that colostrum production is underway, which is essential for the foal’s immune protection.
⚠️ Important tips:
- Once waxing appears, increase monitoring—foaling could happen at any time.
- If the mare drips significant milk before foaling, consult your vet. This can mean loss of valuable colostrum.
- Combine waxing with other signs like relaxation of the tail head, softening of the muscles, and behavioral changes.
Being attentive during these final stages helps ensure a safe delivery and a healthy foal.
We would love to see pictures of your mares that are due or even foals that have already hit the ground! Happy Foaling Season!"
