Caslick's Procedure in Broodmares

Caslick's Procedure in Broodmares - The need to know facts

When it comes to equine reproduction, keeping our mares comfortable and healthy is a high priority. One way we can support this is by performing a Caslick's procedure on selected mares during the breeding season.

What is a "Caslick"?

A "Caslick" or "vulvoplasty", is a straight-forward surgical procedure, performed under local anaesthetic, where the upper portion of the vulva is carefully sutured closed. This helps protect the reproductive tract from air and faecal contamination.

Why do we do it?

1. Some mares have poor perineal conformation, where the vulva doesn't form a tight seal. This can be influended by age, genetics, poor body condition or previous foaling trauma
2. Prevents air and faeces from being drawn into the vagina, therefore reducing the risk of uterine (womb) infections
3. Creates a cleaner, more stable environment for pregnancy

When is it appropriate?

A Caslick's procedure is commonly recommended for:

1. Older mares
2. Mares with a tilted or recessed vulva
3. Mares who have had a difficult foaling previously
4. Mares who repeatedly develop fluid or infections during breeding

When is it removed?

Our vet team will re-open the vulva (under local anaeshetic) before the mare foals, to ensure she can safely deliver. This is a quick and simple procedure done close to her due date.

If you have a broodmare and are unsure whether she would benefit from a "Caslick", reach out to our Equine team for advice or to book an assessment.
