Large reductions in the use of medically important antibiotics for broilers and turkeys have been taking place in the United States over the past five years.
A study released by Mindwalk Consulting Group, which looked at datasets representing up to 93% of the annual US broiler crop and 82% of turkey production, found a substantial usage reduction between 2013 and 2017. The report documents substantial reductions in the use of most medically important antimicrobials in broiler production, regardless of route of administration. The reductions are likely to be the result of tougher guidelines from the US Food and Drug Administration and changes to the veterinary feed directive.
