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

    Thorn Bioscience LLC, 1044 East Chestnut St., Louisville, KY 40204 
has informed FDA that it has transferred ownership of, and all rights 
and interest in, NADA 141-319 for SUCROMATE Equine (deslorelin acetate 
injection) to Dechra, Ltd., Snaygill Industrial Estate, Keighley Rd., 
Skipton, North Yorkshire, BD23 2RW, United Kingdom.
    As provided in the regulatory text, the animal drug regulations are 
amended to reflect these changes of sponsorship.

III. Technical Amendments

    FDA is making the following amendments to improve the accuracy of 
the animal drug regulations:
     21 CFR 510.600 is amended to add Jaguar Animal Health and 
remove Thorn Bioscience LLC from the list of sponsors of approved 
applications.
     21 CFR 520.88h is amended to correct indications for use 
in cats of an oral suspension containing amoxicillin and clavulanate.
     21 CFR 520.2455 is amended to correct a spelling error in 
the limitations for use of tiamulin in drinking water of swine.
     21 CFR 522.230 is amended to add the caution that 
buprenorphine injectable solution is a Schedule III opioid under the 
Controlled Substances Act.
     21 CFR 522.690 is amended to reflect revised indications 
for use of dinoprost tromethamine injectable solution in mares.
     21 CFR 522.1940 is amended to reflect the approved classes 
of cattle and limitations for use of progesterone and estradiol 
benzoate ear implants.
     21 CFR 522.2343 is amended to reflect the approved classes 
of cattle and limitations for use of testosterone propionate and 
estradiol benzoate ear implants.
     21 CFR 556.240 is amended to reflect the use of revised 
food consumption values in establishing permitted concentrations of 
residues of estradiol and related esters in edible tissues of cattle. 
The basis for this action is explained in the FOI Summary for 
supplemental NADA 141-348, approved October 29, 2021. The section is 
also amended to reflect a cross reference for testosterone propionate 
and estradiol benzoate implants, recently redesignated as 21 CFR 
522.2343.
     21 CFR 558.254 is amended to reflect the approved 
conditions of use for famphur in feed.
     21 CFR 558.355 is amended to reflect use of medicated 
feeds containing monensin alone or in combination with bacitracin 
methylenedisalicylate in revised classes of chickens.
     21 CFR 558.555 is amended to correct a spelling error in 
the permitted combination use of semduramicin in medicated feed.
     21 CFR 558.633 is amended to revise expiration dates for 
use of pelleted or crumbled tylvalosin medicated swine feeds.
     21 CFR 558.680 is amended to reflect the correct sponsor 
of an application for use of Type C medicated turkey feeds containing 
zoalene.

IV. Legal Authority

    This final rule is issued under section 512(i) of the Federal Food, 
Drug, and Cosmetic Act (FD&C Act) (21 U.S.C.360b(i)), which requires 
Federal Register publication of ``notice[s] . . . effective as a 
regulation,'' of the conditions of use of approved new animal drugs. 
This rule sets forth

[[Page 17944]]

technical amendments to the regulations to codify recent actions on 
approved new animal drug applications and corrections to improve the 
accuracy of the regulations, and as such does not impose any burden on 
regulated entities.
    Although denominated a rule pursuant to the FD&C Act, this document 
does not meet the definition of ``rule'' in 5 U.S.C. 804(3)(A) because 
it is a ``rule of particular applicability.'' Therefore, it is not 
subject to the congressional review requirements in 5 U.S.C. 801-808. 
Likewise, this is not a rule subject to Executive Order 12866, which 
defines a rule as ``an agency statement of general applicability and 
future effect, which the agency intends to have the force and effect of 
law, that is designed to implement, interpret, or prescribe law or 
policy or to describe the procedure or practice requirements of an 
agency.''
