摘要

Replacement heifer management has a large influence on the reproductive success of beef herds. Overall herd productivity increases when a high percentage of heifers become pregnant early in the first breeding season and a high percentage of first-calf heifers conceive early in the breeding season for a second pregnancy. In order to become pregnant early in the breeding season as a heifer (nulliparous), deliver a live calf, and become pregnant early in the breeding season as a first-calf cow, management of heifer development must optimize nutrition, heifer maturity at the onset of breeding, bull fertility, and overall reproductive success.
