Indications & Usage



DIRECTIONS FOR USE:
Heifers Fed in Confinement for Slaughter:
CycleGuard 500 (melengestrol acetate Type A liquid medicated article) should be thoroughly
mixed in liquid Type C medicated feed which must be fed at 0.5 to 2.0 pounds per head daily
to provide 0.25 to 0.5 mg of melengestrol acetate per head per day. Average daily intakes
approximating the middle of this range provide the most optimal and economical improvements
in rate of gain and feed utilization. Constant daily intakes of 0.35 to 0.50 mg per head per
day give a high degree of estrus suppression. Levels of 0.25 to 0.35 mg provide a lower but
still effective degree of estrus suppression.
Heifers Intended for Breeding:
CycleGuard 500 should be thoroughly mixed in the supplement to provide 0.5 mg of melengestrol
acetate per head per day.

Heifers Fed in Confinement for Slaughter:
Withdrawal periods of three to five days or more should be avoided to prevent the
possibility that the heifers may come into estrus (heat) at loading time.
Heifers Intended for Breeding:
Do not exceed 24 days of feeding of melengestrol acetate to heifers intended for
breeding. A reduced conception rate can be expected if heifers are bred at estruses
observed within 1 to 12 days after withdrawal of melengestrol acetate, whereas heifers
bred at subsequent observed estruses are expected to have normal conception rates.


Warnings And Precautions



WARNINGS: Not for human use. Restricted Drug (California)—Use Only As Directed
PRECAUTIONS: Not effective in steers and spayed heifers.


Dosage & Administration



Type B medicated feed containing 4 to 10 grams melengestrol acetate per ton may
