When is a placenta classified as retained?

The placenta must be passed within three hours of foaling. If the mare has not passed the placenta after three hours, this is classified as retained and it is recommended that you obtain veterinary advice.

Your equine placenta examination checklist:

  • Check the placenta from top to tail that both horns are present, and the full tip of the non-pregnant horn is intact.
  • Check that the placenta is the same colour all over and there are no areas that are particularly light or particularly dark.
  • Turn the placenta over and check both sides, and the inside as well.

    • This does not take the place of a new foal check. A vet should still come out and check the foal within the first 36 hours.
