VFD cutting down on use of CTC
Tri State Livestock News
Chlorotetracycline or CTC seems to be one of the most widely used feed antibiotic products that now require a VFD. "A big concern clients have brought to me is the hand-fed vs. free choice issue with CTC," said Geis. "Since CTC is only approved for anaplasmosis as a free choice feed, it becomes a big issue if a producer had been using it in creep feed for calves on pasture. However, most of our clients were previously using CTC as it was labeled, so the change hasn’t been an earth-shaking issue at this time."
