(a) Dipping and treatment of livestock; general. All
dipping and treatment prescribed in this section must be done under
the supervision of a representative authorized by the commission.
The commission will authorize for use in dipping only those dips that
have been approved by the Animal and Plant Health Inspection Service
of the United States Department of Agriculture and the Texas Animal
Health Commission for use in official dipping to rid animals of the
tick. The concentration of the dipping chemical used must be maintained
in the percentage specified for official use by means of the approved
vat management techniques established for the use of the agent; or,
if applicable, by an officially approved vat side test or field test
of the commission. The owner or caretaker of the livestock is responsible
for presenting the livestock to the dipping vat, dipping the livestock,
and removing the livestock, and will provide such labor as is necessary
to perform all required functions. If the commission requires livestock
to be dipped, the livestock shall be submerged in a vat. A spray-dip
machine may be used in areas where a vat is not reasonably available.
Careful hand spraying may be used for easily restrained horses and
show cattle, and when specifically authorized, certain zoo or domestic
animals. Livestock unable to go through a dipping vat because of size
or physical condition may be hand sprayed. The treatment must be paint
marked so that it can be identified for at least 17 days. The commission
may specifically authorize other treatment methods for free-ranging
wildlife or exotic species.

the premise in accordance with these regulations, except as provided
in paragraph (3)(B) of this subsection.
(B) The 14-day interval may be extended due to circumstances
beyond the control of the owner upon approval by an authorized representative

livestock, the cattle may be treated with injectable doramectin in
lieu of systematic dipping. The owner or caretaker of cattle on an

and treated with injectable doramectin every 25-28 days until the
livestock are moved from the premises in accordance with these regulations,
except as provided in paragraph (3)(B) of this subsection.
(B) Treatment of doramectin shall by administered by
subcutaneous injection by a representative of the commission.

P.O. Box 12966, Austin, Texas 78711.
(C) A dip or treatment is not official unless 100%
of the livestock within the premise affected are dipped or treated
(D) Free-ranging wildlife or exotic livestock that
are found on infested or exposed premises, and which are capable of
hosting fever ticks will be treated by methods approved by the commission
and for the length of time specified by the commission.
(i) Ivermectin medicated corn may be administered to
free-ranging wildlife or exotic livestock by a representative of the
commission following the close of the hunting season, provided that
treatment is terminated at least 60 days prior to the beginning of
the next hunting season to comply with the required withdrawal period.
(ii) Permethrin impregnated roller devices may be used
for topical treatment of free-ranging wildlife or exotic livestock
during periods when ivermectin medicated corn is not administered.
