Abstract

Two field trials were conducted to evaluate various dosage levels of Depo-MGA® for preventing pregnancy in grazing heifers. Injecting Depo-formulated MGA subcutaneously in the ear at dosages of 60, 90 or 120 mg effectively prevented pregnancy for up to 135 days. There was no effect on average daily gain.
