## Abstract

The Food and Drug Administration (FDA) is amending the animal drug regulations to remove those portions reflecting approval of the two new animal drug applications (NADA's) held by Land O'Lakes, Inc., (one for use of tylosin and one for tylosin/sulfamethazine Type A medicated articles), and three NADA's held by ADM Animal Health and Nutrition Div. (one for use of pyrantel tartrate, one for hygromycin B, and one for tylosin/sulfamethazine Type A medicated articles). In a notice published elsewhere in this issue of the Federal Register, FDA is withdrawing approval of these NADA's. The sponsors requested the withdrawal of approval of the NADA's.
