Abstract

Steers in two, 2-year experiments (n = 409) were either given an implant at feedlot arrival or implanted 30 days after feedlot entry. In Experiment 1, steer calves were not implanted at branding and in Experiment 2 calves were implanted at branding. There was no difference in feedlot performance for either experiment. However, in Experiment 1 there was a year by treatment interaction for marbling score suggesting that delaying implant in calves may affect quality grade.
