SUPPLEMENTARY INFORMATION: Hoffmann-La Roche, Inc., 340 Kingsland Rd., 
Nutley, NJ 07110-1199, is the sponsor of NADA 96-298, which currently 
provides for the use of a Type A medicated article containing 20 
percent (90.7 grams (g) per pound) of lasalocid sodium activity in 
making a 68- to 113-g per ton (g/t) Type C medicated feed for broiler 
or fryer chickens and growing turkeys, and a 113-g/t Type C medicated 
feed for chukar partridges, for prevention of coccidiosis. The firm has 
filed a supplemental NADA that expands the use of the Type A medicated 
article for use in making a 113-g/t Type C medicated feed for rabbits 
for the prevention of coccidiosis caused by Eimeria stiedae. Approval 
is based in part on data and information in Public Master File (PMF) 
5042 established under the National Research Support Project (NRSP) 7 
(formerly the Interregional Research Project No. 4 (IR-4)), Southern 
Region, University of Florida, Gainesville, FL 32610.
    The supplemental NADA is approved as of October 20, 1995, and the 
regulations are amended in 21 CFR 558.311 to reflect the approval. The 
basis for approval is discussed in the freedom of information summary.
    In accordance with the freedom of information provisions of part 20 
(21 CFR part 20) and Sec. 514.11(e)(2)(ii) (21 CFR 514.11(e)(2)(ii)), a 
summary of safety and effectiveness data and information submitted to 
support approval of this application may be seen in the Dockets 
Management Branch (HFA-305), Food and Drug Administration, rm. 1-23, 
12420 Parklawn Dr., Rockville, MD 20857, between 9 a.m. and 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 does not 
qualify for marketing exclusivity because no new clinical or field 
investigations (other than bioequivalence or residue studies) and no 
new human food safety studies (other than bioequivalence or residue 
studies) essential to approval of the supplement were conducted or 
sponsored by the applicant.
    The agency has carefully considered the potential environmental 
effects of this action. FDA has concluded that the action will not have 
a significant impact on the human environment, and that an 
environmental impact statement is not required. The agency's finding of 
no significant impact and the evidence supporting that finding, 
contained in an environmental assessment, may be seen in the Dockets 
Management Branch (address above) between 9 a.m. and 4 p.m., Monday 
through Friday.
