You may be aware that starting January 1, 2017, you can no longer stop by a feed store and buy medicated feed containing certain types of antibiotics that were previously classified as over-the-counter (OTC) drugs.  As of January 1, 2017 the FDA requires that clients have a VFD to be able to purchase animal feeds containing these anitbiotics.  For more information please click the following link and read the OSU Extension Veterinary Feed Directive (VFD) Fact Sheet for 4-H Youth Livestock Producers and Families .
