Studies were undertaken to evaluate bloodless castration (B) based on growth and carcass traits. During the first 28 d, bloodless and surgical (S) castrates showed a 51–53% and 68–73% reduction in average daily gain, respectively, compared with intact bulls (I) (P < 0.05) in two trials. Bulls grew faster than steers overall. Carcass traits and grade were similar for B, S and I (P > 0.05).
