dc.description.abstract The percentage of heifers conceiving to artificial insemination (AI) following melengestrol acetate/prostaglandin F2"(MGA®/PG) estrous synchronization can be increased by mass insemination of all heifers not showing estrus by 72 h after PG. Inseminating at 12 h after estrus detection all heifers showing estrus within 72 h after PG; then inseminating those not detected in estrus by 72 h after PG as a group increased the proportion of heifers conceiving to AI by 10.8%. en_US
