estrous synchronization, heifers, mga, prostaglandins
total of 315 yearling heifers were exposed to an estrous synchronization program which consisted of feeding MGA for 14 consecutive days (.5 mg per head per day), followed by a prostaglandin injection 17 days after the last day of MGA feeding. Two hundred forty-seven (78%) of the heifers were detected in heat and artifically inseminated within 5 days after the prostagllandin injection. Response rate ranged from 75 to 84% between ranches and years.
