AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is withdrawing approval 
of a new animal drug application (NADA) held by American Cyanamid Co. 
The NADA provides for the use of maduramicin ammonium in combination 
with chlortetracycline in the feed of broiler chickens for prevention 
of coccidiosis and as an aid in the reduction of mortality due to 
Escherichia coli infections. The firm requested the withdrawal of the 
approval of the NADA. In a final rule published elsewhere in this issue 
of the Federal Register, FDA is amending the regulations by removing 
the portion of the regulation which reflects approval of the NADA.

EFFECTIVE DATE: February 28, 1994.

chlortetracycline in the feed of broiler chickens for the prevention of 
coccidiosis and as an aid in the reduction of mortality due to E. coli

Register, FDA is amending 21 CFR 558.128(c)(5)(xiii) and 558.340(c)(2) 
to reflect withdrawal of the approval.
