What is the earliest a mare can foal?
Foals are born after 11 months gestation (time in the mare’s womb). Thoroughbred breeders work on an average gestation length of 340 days to work out their ‘due dates’. Some mares foal earlier and some later. Foals are not usually viable if born before 290-300 days.
How can I tell when my mare is close to foaling?
The visual signs of a mare’s readiness to foal are:
- Udder distension begins 2-6 weeks prior to foaling.
- Relaxation of the muscles of the croup 7-19 days prior to foaling; relaxation around the tail head, buttocks, and lips of the vulva.
- Teat nipples fill 4-6 days prior to foaling.
- Waxing of the teats 2-4 days before.
