What is Caslicks operation?

  • This procedure was named after a French veterinary surgeon in the 1930s, Dr Caslick, who identified the importance of the preconditions in relation to genital infection in thoroughbred mares. It is a minor veterinary surgical procedure carried out under local anaesthetic by the treating veterinary surgeon, where part of the mare’s vulva is stitched to a specific level to prevent intake of air bacteria resulting in contamination/infection getting into the reproductive tract. This results in infertility in the mare.
