I'm preparing to purchase a Callicrate bander and would appreciate input from anyone who uses one. I've read that delaying castration improves weight gain and that banded calves are typically 20 lbs heavier at weaning than surgically castrated calves. I've also read that bulls typically gain 15% faster and convert feed 20% more efficiently than castrated steers, due to testosterone. Reportedly, castration at five months should be done if the calves are left with open cows, and eight months if they are weaned or running with bred cows. Anyone have experience with these numbers? Many producers castrate when preconditioning shots are given, but I've heard that some producers are allowing their bulls to get very heavy before castrating, but not too close to finish age. Can this work? I'd always thought that delaying castration would adversely impact on meat quality. What's been your experience?
