Nebraska Beef Cattle Reports

A two-year study tested the hypothesis that growth rate interacts with bull exposure to influence age at puberty in heifers. Heifers exposed to sterile bulls and fed to achieve a high growth rate (1.8 lb/day) attained puberty 73 days earlier than heifers not exposed to bulls and fed to a moderate growth rate (1.3 lb/day). Heifers exposed to bulls and fed to achieve a moderate growth rate attained puberty at ages similar to heifers not exposed to bulls and fed to a high growth rate. Furthermore. heifers receiving these two treatments attained puberty 23 days earlier than heifers not exposed …
