Abstract

A two-year study was conducted with crossbred beef cows to determine whether supplementation with fat from whole corn germ either pre- or postpartum influenced ovarian activity before the breeding season, pregnancy rates, calving interval, calf performance, or serum leptin concentration. Supplements were fed for approximately 45 days before or 45 days after calving. Cows supplemented prepartum with fat from whole corn germ had shorter calving intervals. Ovarian activity before the breeding season, pregnancy rate, calf growth, and serum leptin were not different between groups.
