Some cattle feeds and blocks contain drugs.
They are called medicated feeds or blocks and as such must be labeled and stored properly. One common reason for drug residues occurring is mistakenly feeding a medicated feed or block intended for use in calves or replacement heifers to the lactating herd. All medicated feeds or blocks should be segregated from non-medicated feeds or blocks. Medicated feeds or blocks intended for non-lactating cattle must be stored inaccessible to lactating dairy cattle. Feed or feed blocks may not contain drugs or other feed additives not specifically labeled for that use.
