1. A method for synchronizing time of insemination in a gilt, the method comprising the steps of:
administering to the gilt a hormone for synchronizing estrus;
monitoring estrus on the fifth day after the last daily administration of the hormone for synchronizing estrus, and then, if the gilt is in estrus, administering to the gilt a single dose of a gonadotropin-releasing hormone, without administration of any other hormone for synchronizing ovulation, and
inseminating the gilt on the fifth day after the last daily administration of the hormone for synchronizing estrus; and
inseminating the gilt on the sixth day after the last daily administration of the hormone for synchronizing estrus wherein estrus is not monitored on the sixth day after the last daily administration of the hormone for synchronizing estrus.
