What is the difference between a Foal Alert and a Caslicks?
Foal Alert Transmitter is a device that is sutured into both sides of the vulvar lips of a mare prior to foaling. Once a mare begins to foal, the activating pin is pulled from the device as the foal’s legs pass through the birth canal separating the vulvar lips. The removal of the pin alerts a transmitter that emits a loud beeping sound. It can also be attached to a dialer, and the phone line, where the Foal Alert can actually call the foaling attendant.
A caslicks is minor surgical procedure used to suture together the upper portion of a mare’s vulvar lips. After a thorough cleaning, the upper portion of the vulvar lips are blocked with lidocaine and a thin line of tissue is removed from both sides. The incised tissue from both sides is then sutured together and allowed to heal. After healing, the sutures are removed and the upper portion of the vulvar lips will have grown together. This procedure reduces the size of the vulvar opening. The caslicks procedure is beneficial for mares with poor vulvar conformation to help prevent them from developing uterine infections and pneumovagina. This procedure also helps prevent placentitis when used in pregnant mares.
