January is an extremely important "checkpoint" in spring heifer development programs. The key to proper heifer development lies in understanding the factors that influence conception in yearling heifers.
One key factor regulating heifer fertility is age at puberty. Most producers do not consider age at puberty of their heifers to be a major problem, yet few know how many heifers are actually cyclic at the beginning of the breeding season.
