(a)A feed manufacturing facility must possess a medicated feed mill license in order to manufacture a Type B or Type C medicated feed from a Category II, Type A medicated article.

(b)The manufacture of the following types of feed are exempt from the required license, unless otherwise specified:

(1)Type B or Type C medicated feed using Category I, Type A medicated articles or Category I, Type B or Type C medicated feeds; and

(2)Type B or Type C medicated feed using Category II, Type B or Type C medicated feeds.

(c)The use of Type B and Type C medicated feeds shall also conform to the conditions of use provided for in subpart B of this part.

(d)This paragraph identifies each drug by category, the maximum level of drug in Type B medicated feeds, and the assay limits for the drug in Type A medicated articles and Type B and Type C medicated feeds, as follows: Category I Drug Assay limits percent 1 Type A Type B maximum

For those drugs that have two range limits, the first set is for a Type B medicated feed and the second set is for a Type C medicated feed. These values (ranges) have been assigned in order to provide for the possibility of dilution of a Type B medicated feed with lower assay limits to make Type C medicated feed.
