foetus plus the membranes and fluids, to the extent that it tears. The muscles themselves may

tear or the prepubic tendon which attaches them to the front of the pelvis can partially or
VetBooks.ir completely rupture. The signs include an area of oedema (swelling) up to 10–15 cm (4–6 in)
thick, extending along the ventral midline in front of the udder (Figure 19.21). The mare is

often uncomfortable; she may show colicky signs and resent the area being touched. The
udder may appear to have moved forwards.

The treatment is restricted exercise and non-steroidal anti-inflammatory drugs. A well-

padded abdominal support bandage may be applied. Some mares are able to foal unassisted,
but the abdominal wall is often too weak to push the foal out. An assisted delivery or
caesarean section may be required, so the birth should be supervised. It may be possible to

repair the defect surgically but this can be very difficult. Further pregnancy puts the welfare
of the mare at risk.

MARE RUNNING MILK

If the mare runs milk prior to foaling, an alternate source of colostrum must be available (see
page 640).
