This tool developed in USA is for the purpose of ensuring bulls can achieve the fastest possible growth rates, without need of artificial hormonal growth promotants. (Proven 15% improvements.) They are then easily and humanely castrated at the latest appropriate stage. The Callicrate Bander can be used on larger animals to quickly, cleanly, non-surgically and most important humanely remove the testicles. Bull management can be modified to castrate nearer maturity maximising the growth induced by natural testosterone.?The procedure is based on the use of a strong rubber cord inserted into a patented application device. The cord is stretched over the scrotum before being tightened by a ratchet mechanism and then locked firmly into position using a metal clip. With a little practice the procedure is both faster and safer than using a knife or other castration instruments. Loop prices above are each.?* The Bander kit includes Bander tool, loop cutter, 5 loops and demonstration video, all supplied in a sturdy kit box.
