Active Drug Ingredient: Zilpaterol hydrochloride 21.77 g/lb (48 g/kg)

Inert Ingredients: Ground corncobs, surfactant and binder

PERMITTED CLAIMS AND LIMITATIONS:

MIXING DIRECTIONS (COMPLETE FEED):

Dilute Zilmax Type A medicated article in a suitable carrier before addition to the final feed. A dilution of 1 part Zilmax Type A medicated article and 9 parts carrier (0.68 g zilpaterol/lb) is the suggested working pre-blend. Thoroughly mix the working pre-blend with feed to ensure complete and uniform distribution of the Zilmax Type A medicated article. Zilmax Type A medicated article and working pre-blend addition rates for complete feeds of varying dry matter are in the following table.

Type B medicated feed may also be used after diluting Zilmax Type A medicated article before addition to the final feed. Thoroughly mix Zilmax Type A medicated article into appropriate feed ingredients to make a ton of Type B medicated feed (or Type B medicated liquid feed) according to the table below to obtain the proper concentration in Type C medicated complete feed (6.8 g/ton).

MIXING DIRECTIONS (COMPONENT FEED):

Thoroughly mix Zilmax Type A medicated article into appropriate feed ingredients to make one ton of Type B medicated feed (see above). To obtain the proper concentration of zilpaterol in Type C medicated feed (from a range of 6.8 to 24 g/ton), the following table gives examples of how some Type C medicated component feed concentrations can be prepared from Type B medicated feed.

MIXING DIRECTIONS FOR ALL TYPE B MEDICATED LIQUID FEED USED TO PREPARE TYPE C MEDICATED FEEDS (COMPLETE AND COMPONENT):

• Type B medicated liquid feed should be in a pH range of 3.8 to 7.5
• Type B medicated liquid feed should be recirculated or agitated daily and prior to use for 10 to 20 minutes
• Type B medicated liquid feed can be manufactured containing 68 to 680 g zilpaterol hydrochloride/ton
• Type B medicated liquid feed must be thoroughly mixed with other feed ingredients to make a Type C medicated feed before feeding.

For Type B medicated liquid feed stored in recirculating tank systems: Recirculate immediately prior to use for not less than 10 minutes, moving not less than 1 percent of the tank contents per minute from the bottom of the tank to the top. Recirculate daily as described even when not used.

For liquid feeds stored in mechanical, air, or other agitation-type tank systems: Agitate immediately prior to use for not less than 10 minutes, creating turbulence at the bottom of the tank that is visible at the top. Agitate daily as described even when not used.

MIXING DIRECTIONS (COMPLETE FEED FROM TYPE B MEDICATED LIQUID FEED):

Directions to prepare a Type B medicated liquid feed are identical to directions for dry Type B medicated feed. See MIXING DIRECTIONS (COMPLETE FEED) for dry Type B medicated feed.

MIXING DIRECTIONS (COMPONENT FEED FROM TYPE B MEDICATED LIQUID FEED):

Directions to prepare a Type B medicated liquid feed are identical to directions for dry Type B medicated feed. See MIXING DIRECTIONS (COMPONENT FEED) for dry Type B medicated feed.

FEEDING DIRECTIONS (COMPLETE FEED):

Feed continuously to cattle during the last 20 to 40 days on feed as the sole ration, containing 6.8 g/ton zilpaterol (7.5 ppm on 90% dry matter basis), to provide 60 to 90 mg zilpaterol hydrochloride per head per day. The amount of zilpaterol hydrochloride consumed daily by cattle will depend on the consumption rate of the Type C medicated feed. Zilpaterol hydrochloride consumption will range between 60 and 90 mg per head per day based on the Type C medicated feed consumption rates in the table below.

FEEDING DIRECTIONS (COMPONENT FEED):

Feed continuously to cattle during the last 20 to 40 days on feed, in a feed containing no less than 6.8 g/ton and no more than 24 g/ton zilpaterol (90% dry matter basis), to provide 60 mg zilpaterol hydrochloride per head per day.

WITHDRAWAL PERIOD: 3 days

CAUTION: Not for use in animals intended for breeding. Do not allow horses or other equines access to feed containing zilpaterol. Do not use in veal calves. Not to be fed to cattle in excess of 90 mg zilpaterol/head/day in complete feed. If pen consumption of complete feed exceeds 26.5 lb/head/day (90% dry matter basis), zilpaterol should not be fed in complete feed.

YOU MAY NOTICE:

Animals receiving zilpaterol hydrochloride may exhibit increased respiratory rate as well as elevated levels of creatine phosphokinase (CPK) and creatinine.
