The Callicrate WEE bander has been developedfor safe, and 100% reliable, castration of smallanimals - calves, lambs, kids etc. This system is astep up from regular rubber-ring castration, where amore reliable and humane system is required. TheWEE device allows a wider applicatior opening, andthen a more consistent tension when released. Theextra tension is critical in stopping all blood supplyto the testicles. Trials on lambs using traditionaland Callicrate castration showed much less painand stress in the Callicrate group.
