What term on a feed label indicates the presence of drugs in the feed?

The term "Medicated" on a feed label specifically refers to the presence of drugs incorporated into the feed formulation. This label indicates that the feed contains substances intended to treat or prevent disease in animals, thereby promoting animal health and productivity. Such medicated feeds are regulated by governmental agencies to ensure that they are used safely and effectively.

The other terms listed do not indicate the presence of drugs. "Organic" refers to feed that is produced without synthetic fertilizers or pesticides and is subject to specific agricultural practices. "Supplemented" suggests that additional nutrients or additives are provided to enhance the diet but does not necessarily involve medication. "Enriched" typically indicates that certain nutrients have been added to improve the nutritional profile of the feed but again does not imply the inclusion of drugs. Thus, "Medicated" is the accurate term to identify feed that contains drugs.
