MGA Pellet

Withdrawal periods of 3 to 5 days should be avoided to prevent the possibility that heifers may come into estrus (heat) at loading time. Not effective in steers and spayed heifers. Heifers intended for reproduction: Do not exceed 24 days of feeding. 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 estrus are expected to have normal conception rates.
