Abstract

A 5-year study evaluated the effects of protein supplementation to beef cows grazing cornstalks in late gestation on both cow and calf weight, and the reproductive performance of heifer progeny. Supplementation improved cow BCS at the end of cornstalk grazing. Calf weight, cow pregnancy rates, and reproductive traits of subsequent heifer progeny were not impacted by supplementation. Supplementing mid- to late-gestation beef cows grazing cornstalks has minimal impact on cow performance or fetal programming of heifer progeny.
