DIRECTIONS FOR USE:
Heifers Fed in Confinement for Slaughter: MGA 200 (melengestrol acetate Type A medicated article) should be thoroughly mixed in the supplement to provide 0.25 to 0.50 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: MGA 200 should be thoroughly mixed in the supplement to provide 0.5 mg of melengestrol acetate per head per day.
NOT FOR HUMAN USE.
CAUTION: 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.

Labeling for such Type B feeds shall contain directions for manufacturing Type C medicated feeds containing 0.25 to 2.0 grams melengestrol acetate per ton (0.125–1.0 mg/lb). The Type C medicated feed, containing melengestrol acetate, must be top dressed on grain or roughage or mixed with a complete ration at the rate of 0.5 to 2.0 pounds per head per day.
Good manufacturing practice regulations must be adhered to in manufacturing feeds containing MGA 200.
