The Callicrate WEE bander has been developed for safe, and 100% reliable, castration of small animals - calves, lambs, kids etc. This system is a step up from regular rubber-ring castration, where a more reliable and humane system is required. The WEE device allows a wider applicatior opening, and then a more consistent tension when released. The extra tension is critical in stopping all blood supply to the testicles. Trials on lambs using traditional and Callicrate castration showed much less pain and stress in the Callicrate group.
