Equine Parturition
Average gestational length for a horse is 335 to 342 days, but can
go as long as 360 days.
Prior to foaling we recommend that if the mare is to give birth in a
stall that the stall is no smaller than 14’ by 14’ and is cleaned
and bedded with straw. If preparing to foal in the pasture we
recommend the mare be placed in a dry paddock or pasture with
appropriate fencing so that the foal cannot accidentally become
separated from the dam.
Stages of Parturition
Stage 1:
Duration: Approximately 30 minutes to 4 hours
Signs: Mare appears restless and may exhibit signs of similar
to colic such as looking at her side, sweating, and lie down and get
up repeatedly.
At this time you may elect to wrap the mare’s tail and the perineal
area and udder may be cleaned.
The chorioallantois will rupture (water breaking) releasing the
allantoic fluid.
Stage 2:
Duration: Approximately 30 minutes
What you should expect to see: A white transparent membrane (amnion)
and the foal should be positioned with the feet pointed down and
should be in a foot-nose-foot position during birth.
Stage 3:
Duration: 1-4 hours
Expulsion of the placenta (afterbirth). We recommend tying the
placenta in several knots if the placenta is not expelled directly
after giving birth to prevent the mare or foal from stepping on it.
When to call the veterinarian
Premature Placental Separation (Red Bagging): During stage one
if the chorioallantois does not rupture and the red surface of this
is observed at the vulva this is an emergency. You must break
this open as the foal’s ability to receive oxygen has been
compromised. Break open first then call the veterinarian.
Passage of the foal: If stage two does not progress with
expulsion of the foal within 10-15 minutes call a veterinarian.
If the foal’s presentation appears to be anything other than hooves
down, front feet first in a diving position call a veterinarian.
Umbilical Cord: Never cut the cord. The umbilical cord will often
break when the foal or mare gets up. If the umbilical cord
does not break it can be removed approximately 1 inch from the
foal’s abdomen in a twisting fashion. Contact a veterinarian
prior to attempting to remove the cord.
Passage of the Placenta: Call if the placenta has not been passed
within 3-4 hours. We prefer that the placenta be kept once it
has been passed in a cool area preferably in a covered bucket with
water until the scheduled new foal exam appointment to determine
that there are no abnormalities associated with the placenta and
that it has been passed intact.
Call if the foal:
We recommend scheduling an appointment between the first 12 and
24 hours following birth to evaluate the health of the foal and the
mare.
