Heifers Fed in Confinement for Slaughter:
For increased rate of Weight Gain, Improved Feed Efficiency and Suppression of Estrus (Heat).
Heifers Intended for Breeding:
For Suppression of Estrus (Heat).
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. Averagedaily 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.
WARNINGS: Not for human use. Restricted Drug (California) — Use Only As Directed
Not effective in steers and spayed heifers.
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.
MIXING DIRECTIONS:
Liquid Type B and C medicated feeds containing melengestrol acetate must have a pH of 4.0 to 8.0 and their labels must bear
appropriate mixing directions. Mixing directions for liquid Type B or C feeds stored in recirculation tank systems are: "Recirculate
immediately prior to use for no 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 directed in this paragraph even when the Type B (or C) feed is not used." Mixing
directions for liquid Type B and C feeds stored in mechanical, air or other agitation-type tank systems are: "Agitate immediately
prior to use for not less than 10 minutes, creating a turbulence at the bottom of the tank that is visible at the top. Agitate daily, as
directed in this paragraph, even when the Type B (or C) feed is not used."
Intermediate medicated feeds should not be made from CycleGuard 500 except as a part of a continuous mixing operation to make
a complete liquid Type B or Type C medicated feed.
Thoroughly mix 0.5 to 4 pounds of CycleGuard 500 per ton of a non-medicated feed to prepare a Type C medicated feed containing 0.25 to 2.0 grams of melengestrol acetate per ton. The following Table may be used as a guide in determining the amount of Cycleguard 500 to be added to prepare a ton of Type C medicated feed.

CYCLEGUARD® 500 (melengestrol acetate Type A liquid medicated article): Not effective in steers or spayed heifers. 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. When used in heifers intended for breeding, do not exceed 24 days. A reduced conception rate can be expected within 1 to 12 days after the withdrawal of melengestrol acetate. Heifers bred on subsequent observed estruses will have normal conception rates. To report adverse effects, access medical information, or obtain additional product information, call 1-877-426-7765.
