21 CFR Part 558


New Animal Drugs For Use In Animal Feeds; Bambermycins

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule.

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

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to reflect approval of a supplemental new animal drug 
application (NADA) filed by Hoechst-Roussel Agri-Vet Co. The supplement 
provides for using liquid bambermycins Type B medicated feeds to make 
Type C medicated feeds for cattle fed in confinement for slaughter for 
increased rate of weight gain and improved feed efficiency.

EFFECTIVE DATE: February 25, 1997.

FOR FURTHER INFORMATION CONTACT: Russell G. Arnold, Center for 
Veterinary Medicine (HFV-142), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-594-1674.

SUPPLEMENTARY INFORMATION: Hoechst-Roussel Agri-Vet Co., Route 202-206, 
P.O. Box 2500, Somerville, NJ 08876-1258, filed supplemental NADA 141-
034 that provides for using 10-gram per pound (g/lb) 
Flavomycin<Register> (bambermycins) Type A medicated articles to make 
40 to 800 g/ton liquid Type B medicated feeds, the liquid Type B feeds 
used to make dry Type C medicated feeds. The Type C feeds containing 1 
to 4 g/ton bambermycins are for cattle fed in confinement for slaughter 
to provide 10 to 20 milligrams bambermycins per head per day for 
increased rate of weight gain and improved feed efficiency. The 
regulations are amended in Sec. 558.95 (21 CFR 558.95) by adding new 
paragraph (a)(5), by redesignating paragraph (b) as paragraph (d), and 
by revising newly redesignated paragraph (d)(4)(i)(b) to reflect the 
approval.
    Furthermore, use of liquid Type B feeds to make Type C feeds 
requires publication of specifications and expiration information. New 
Sec. 558.95(b) is established to reflect the Type B feed specifications 
and expiration information. In the interest of issuing uniform 
regulations in the future, new Sec. 558.95(c) is also established at 
this time and reserved for future use.
    Approval of this supplement did not require submission of 
additional safety or efficacy data. A freedom of information (FOI) 
summary as in 21 CFR part 20 and 514.11(e)(2)(ii) is not required. An 
FOI summary submitted to support approval of the original application 
may be seen in the Dockets Management Branch (HFA-305), Food and Drug 
Administration, 12420 Parklawn Dr., rm. 1-23, Rockville, MD 20857, from 
9 a.m. to 4 p.m., Monday through Friday.
    Under section 512(c)(2)(F)(iii) of the Federal Food, Drug, and 
Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(iii)), this approval for food 
producing animals does not qualify for marketing exclusivity because 
the supplement does not contain substantial evidence of effectiveness 
of the drug involved, any studies of animal safety or human food safety 
studies (other than bioequivalence or residue studies) required for 
approval of the supplement and conducted or sponsored by the applicant.
    The agency has determined under 21 CFR 25.24(d)(1)(iii) that this 
action is of a type that does not individually or cumulatively have a 
significant effect on the human environment. Therefore, neither an 
environmental assessment nor an environmental impact statement is 
required.
