Abstract

Cows grazed winter range (WR) or corn residue (CR) during late gestation and received protein supplement (PS) of 1 lb/day 28% CP cubes or no supplement (NS). Pre-calving and pre-breeding body weight (BW) and body condition score (BCS) were greater for PS and CR cows. Pregnancy rate was not affected by treatments. Calf weaning BW was greater for PS cows that grazed WR. Final BW and 12th rib fat tended to be greater for steers from cows on CR. Steers from PS cows graded a higher proportion USDA Choice or greater. More heifers were pubertal before breed¬ing from dams receiving PS on WR. Dam treatment did not affect heifer pregnancy rate.
